We present a comparison of the results of the Oxford unicompartmental knee arthroplasty in patients younger and older than 60 years of age. The ten-year all-cause survival of the | 60 years of age group (52) was 91% (95% confidence interval (CI) 12), while in the | or = 60 years of age group (512), the figure was 96% (95% CI 3). For the younger group, the mean Hospital for Special Surgery score at ten-year follow-up (n = 21) was 94 of 100, compared with a mean of 86 of 100 for the older group (n = 135). The results show that the Oxford unicompartmental arthroplasty can achieve ten-year results that are comparable to total knee arthroplasty in patients | 60 years of age. We conclude that for patients aged over 50, age should not be considered a contraindication for this procedure.

BACKGROUND: The role of unicompartmental arthroplasty in managing osteoarthritis of the knee remains controversial. The Oxford medial unicompartmental arthroplasty employs a fully congruent mobile bearing intended to reduce wear and increase the lifespan of the implant. Long-term second decade results are required to establish if the design aim can be met. QUESTIONS/PURPOSES: We report the (1) 20-year survivorship for the Oxford mobile bearing medial unicompartmental knee arthroplasty; (2) reasons for the revisions; and (3) time to revision. METHODS: We reviewed a series of 543 patients who underwent 682 medial Oxford meniscal bearing unicompartmental knee arthroplasties performed between 1983 and January 2005. The mean age at implantation was 69.7 years (range, 48-94 years). The median followup was 5.9 years (range, 0.5 to 22 years). One hundred and forty-one patients (172 knees) died. None were lost to followup. The primary outcome was 20-year survival, a key variable in assessing the longevity of

N2 - Purpose: Preoperative range of motion (ROM) has been regarded as one of the most important factors in predicting postoperative ROM following total knee arthroplasty (TKA). Mobile-bearing TKA designs have been suggested to possibly improve the knee kinematics compared to fixed-bearing designs. The purpose of this study was to examine the difference in postoperative flexion as a function of preoperative flexion in a consecutive series of TKAs done using a posterior-stabilized rotating-platform prosthesis. Methods: ROM was assessed in 153 consecutive TKAs done using a rotating-platform posterior cruciate-substituting design. Patients were divided into two groups based on their preoperative ROM (Group 1 , 95°, Group 2 , 95°). The Knee Society Score ...

The aim of this to study was to compare the previously unreported long-term survival outcome of the Oxford medial unicompartmental knee arthroplasty (UKA) performed by trainee surgeons and consultants.We therefore identified a previously unreported cohort of 1084 knees in 947 patients who had a UKA inserted for anteromedial knee arthritis by consultants and surgeons in training, at a tertiary arthroplasty centre and performed survival analysis on the group with revision as the endpoint.The ten-year cumulative survival rate for revision or exchange of any part of the prosthetic components was 93.2% (95% confidence interval (CI) 86.1 to 100, number at risk 45). Consultant surgeons had a nine-year cumulative survival rate of 93.9% (95% CI 90.2 to 97.6, number at risk 16). Trainee surgeons had a cumulative nine-year survival rate of 93.0% (95% CI 90.3 to 95.7, number at risk 35). Although there was no differences in implant survival between consultants and trainees (p = 0.30), there was a difference in

Total knee arthroplasty is regarded as the most effective treatment for severe knee osteoarthritis. The influential factors of blood loss in total knee arthroplasty remain controversial. The study aims to explore the influential factors of blood loss in total knee arthroplasty comprehensively. Three hundred and four osteoarthritis patients undergoing unilateral primary total knee arthroplasty were enrolled. Demographic characteristics, laboratory results, surgical protocol, and hemostatic and anticoagulation drugs were collected. Estimation of blood loss was calculated using the Gross equation. Multivariable stepwise linear regression analysis was performed to find out the influential factors. Total blood loss reached the biggest volume (1346 ± 671 mL) in the post-operative third day. Hidden blood loss reached 465 ± 358 mL. Gender, tranexamic acid, prosthesis type, and drainage were proven to be positively correlated with the total blood loss (all P | 0.05). Male appeared to suffer more surgical blood

High procedure volume and dedication to unicompartmental knee arthroplasty (UKA) has been suggested to improve revision rates. This study aimed to quantify the annual hospital volume effect on revision risk in Oxfordu nicompartmental knee arthroplasty in the Nordic countries. 14,496 cases of cemented medial Oxford III UKA were identified in 126 hospitals in the four countries included in the Nordic Arthroplasty Register Association (NARA) database from 2000 to 2012. Hospitals were divided by quartiles into 4 annual procedure volume groups (≤11, 12-23, 24-43 and ≥44). The outcome was revision risk after 2 and 10 years calculated using Kaplan Meier method. Multivariate Cox regression analysis was used to assess the Hazard Ratio (HR) of any revision due to specific reasons with 95% confidence intervals (CI). The implant survival was 80% at 10 years in the volume group ≤11 procedures per year compared to 83% in other volume groups. The HR adjusted for age category, sex, year of surgery and

With total knee replacement being such a successful treatment for arthritis of the knee, can it be improved? Survival rates for total knee replacement at 20 years are now reaching 80%. 10 year survival is in the region of 95%.. In the past Surgeons have looked at survival rates, range of movement and x-ray findings following knee replacements. More recently interest has been shown in patient recorded outcome measures particularly with regard to patient satisfaction. In the UK we now have National Joint Registry which has been recording data on hip and knee replacements since 2004. A recent survey of 8,000 total knee replacements from this survey showed that the satisfaction rate following total knee replacement was 82%. Similar research in Scandinavia, North America has shown comparable satisfaction rates for this surgery. When one looks at total hip replacement the satisfaction rates are in the mid to high 90s. So why are patients not so satisfied after knee replacement surgery compared to hip ...

Published in Anesth Analg. 2014 Jun;118(6):1370-7. Authors: Hanson NA et al. BACKGROUND:. Adductor canal blocks have shown promise in reducing postoperative pain in total knee arthroplasty patients. No randomized, controlled studies, however, evaluate the opioid-sparing benefits of a continuous 0.2% ropivacaine infusion at the adductor canal. We hypothesized that a continuous adductor canal block would decrease postoperative opioid consumption.. METHODS:. Eighty subjects presenting for primary unilateral total knee arthroplasty were randomized to receive either a continuous ultrasound-guided adductor canal block with 0.2% ropivacaine or a sham catheter. All subjects received a preoperative single-injection femoral nerve block with spinal anesthesia as is standard of care at our institution. Cumulative IV morphine consumption 48 hours after surgery was evaluated with analysis of covariance, adjusted for baseline characteristics. Secondary outcomes included resting pain scores (numeric rating ...

Stability of the knee is a complex issue and involves ligaments that behave differently on the medial and lateral side. Correct positioning of the components and adequate soft-tissue balancing are critical steps in successful total knee arthroplasty1. A total knee prosthesis that is implanted too tightly may cause limited range of motion and compromise patient satisfaction. A total knee replacement that is implanted too loosely will be unstable2. Medial-lateral instability is the most common type of instability and may result from incompetent collateral ligaments, incomplete correction of a preoperative deformity, or incorrect bone cuts3. Separate studies have identified instability as a leading cause of early clinical failure of a primary total knee replacement, resulting in revision within three to five years4,5. ...

PY - 1999/4/1. Y1 - 1999/4/1. N2 - The charts of 21 patients (22 knees) with significant radiographic changes of the patella after total knee arthroplasty were reviewed. The average patient age was 73 years, and average follow-up after arthroplasty was 7.3 years. Lateral release, fat pad excision, quadriceps tendon release, and previous surgery were implicated in the etiology of fracture of the patella. Five cases had type 1 pattern (sclerosis, fragmentation, and no fracture), 5 cases had type 2 pattern (undisplaced fracture and fragmentation), and 12 cases had type 3 pattern (displaced fracture and fragmentation). Type 1 and 2 patterns required no surgical treatment and were rated good to excellent according to the Hospital for Special Surgery Disability Score Sheet. Patients with a type 3 pattern who did not ...

This study compares in vivo sagittal plane kinematics of the Oxford mobile-bearing unicompartmental knee arthroplasty (UKA) at 1 and 10 years postsurgery (10 knees) with a fixed-bearing total knee arthroplasty (TKA) (5 knees) and the normal knee (5 knees), using dynamic fluoroscopic measurement of the patellar tendon angle. The Oxford UKA preserved normal changes in patellar tendon angle with flexion, and this was maintained at 10 years. In contrast, an abnormal pattern was seen with the TKA. The results suggest that a normal pattern of sagittal plane knee kinematics exists following Oxford medial UKA and imply that anterior cruciate ligament function is maintained in the long term.

Background and purpose - The population of the Nordic countries is aging and the number of elderly patients undergoing total knee arthroplasty (TKA) is also expected to increase. Reliable fixation methods are essential to avoid revisions. We compared the survival of different TKA fixation concepts with cemented fixation as the gold standard. Patients and methods - We used data from the Nordic Arthroplasty Register Association (NARA) database of 265,877 unconstrained TKAs performed for patients aged ≥ 65 years with primary knee osteoarthritis between 2000 and 2016. Kaplan-Meier (KM) survival analysis with 95% confidence intervals (CI) and the Cox multiple-regression model were used to compare the revision risk of the fixation methods. Results - Cemented fixation was used in 243,166 cases, uncemented in 8,000, hybrid (uncemented femur with cemented tibia) in 14,248, and inverse hybrid (cemented femur with uncemented tibia) fixation in 463 cases. The 10-year KM survivorship (95% CI) of cemented ...

The most common reasons for revision of unicompartmental knee arthroplasty (UKA) are loosening and pain. Cementless components may reduce the revision rate. The aim of this study was to compare the fixation and clinical outcome of cementless and cemented Oxford UKAs. A total of 43 patients were randomised to receive either a cemented or a cementless Oxford UKA and were followed for two years with radiostereometric analysis (RSA), radiographs aligned with the bone-implant interfaces and clinical scores. The femoral components migrated significantly during the first year (mean 0.2 mm) but not during the second. There was no significant difference in the extent of migration between cemented and cementless femoral components in either the first or the second year. In the first year the cementless tibial components subsided significantly more than the cemented components (mean 0.28 mm (sd 0.17) vs. 0.09 mm (sd 0.19 mm)). In the second year, although there was a small amount of subsidence (mean 0.05 mm) there

Aim. The need to resurface or not the patella during total knee arthroplasty is still an open problem. Some surgeons always recommend to replace the patella, others suggest to not replace routinely the patella and others to replace it only in selected cases. The purpose of this study was to compare clinical results of knee prosthesis with or without patella replacement in a series of 30 patients treated for bilateral knee arthritis using a medial pivot prosthesis (Advance Wright, Arlington TN ...

No data are available to describe six-degree-of-freedom (6-DOF) knee-joint kinematics for one complete cycle of overground walking following total knee arthroplasty (TKA). The aims of this study were firstly, to measure 6-DOF knee-joint kinematics and condylar motion for overground walking following TKA; and secondly, to determine whether such data differed between overground and treadmill gait when participants walked at the same speed during both tasks. A unique mobile biplane X-ray imaging system enabled accurate measurement of 6-DOF TKA knee kinematics during overground walking by simultaneously tracking and imaging the joint. The largest rotations occurred for flexion-extension and internal-external rotation whereas the largest translations were associated with joint distraction and anterior-posterior drawer. Strong associations were found between flexion-extension and adduction-abduction (R2 = 0.92), joint distraction (R2 = 1.00), and anterior-posterior translation (R2 = 0.77), providing

Knee replacement surgery (knee arthroplasty) is when damaged knee joint surfaces are replaced to restore function and relieve pain and disability.

The most common previously reported modes of failure of unicompartmental knee arthroplasty (UKA) in the first and second decades are polyethylene wear, progression of arthritis, and component loosening. The purpose of this study is to describe an early mechanism of failure of the medial UKA. Thirty-two consecutive revisions from UKA to total knee arthroplasty were retrospectively reviewed. The predominant mode of failure observed in 15 (47%) of 32 knees was medial tibial collapse. Of these, 87% were an all-polyethylene design, and 7 of 15 failed in less than 16 months and required more complex reconstruction with stems, augments, and screws and cement. Increased tibial slope was associated with posterior tibial collapse. In our series, knees that failed by medial tibial collapse had more significant bone defects and required more complex reconstructions than is currently reported in the literature.

|p|The incidence of revision total knee arthroplasty (TKA) has increased steadily in the United States over the last decade. A 2010 study of the Nationwide Implant Sample Database found that the most common type (35.2%) revision TKA involved the removal of both the femoral and tibial components. For most orthopaedic surgeons, undertaking such a case is no small task, as it requires rigorous preoperative planning and thorough knowledge of knee anatomy. In light of the increasing incidence of revision TKA, we have created this video to demonstrate the key steps in exposing a previously operated knee and removing well-fixed components. We begin by reviewing the vascular supply to the anterior knee and how surgeons should choose a surgical incision to utilize. We then introduce our approach to systematically exposing the knee in a step-wise fashion: clearing the medial and lateral gutters, performing an anteromedial tibial release, and mobilizing the extensor mechanism. We also describe advanced techniques

A new study reveals that number of total knee replacement surgeries more than tripled and the number of total hip replacements doubled between 1993 and 2009.

Measured resection and gap balancing are two distinct methods for proper femoral component alignment in total knee arthroplasty. Decision-making between the two techniques is controversial. The aim of this systematic review and meta-analysis was to compare measured resection and gap balancing with regard to the radiological and clinical benefits, and to examine whether this change the conclusions from previous trails. A systematic literature search of the medical literature from January 1990 to February 2015 was performed. We selected six randomized controlled trials and five prospective cohort studies comparing gap balancing and measured resection in patients undergoing primary total knee arthroplasty. Data from included studies were pooled with use of fixed-effects and random-effects models with standard mean differences and risk ratios for continuous and dichotomous variables, respectively. Heterogeneity across studies was assessed with calculation of the I2 statistic. A total of 857 knees from 11

AU - Scully, Sean P.. PY - 2006/5. Y1 - 2006/5. N2 - Revision total knee arthroplasty can be considerably more difficult in cases involving severe bone loss, complete absence of collateral ligaments, and persistent periprosthetic supracondylar femoral fractures. Modular segmental endoprosthetic distal femur replacement is a limb salvage option when other surgical options are unfeasible. The clinical performance of rotating hinge knee prostheses has greatly improved with the evolution of second and third generation designs. The increased freedom of rotation decreases the prosthetic bone stresses and the longevity. While designs have improved, the prostheses still do not match the function and longevity of condylar components with approximately a 90% survivorship at 20 years. The modular endoprosthesis ...

BACKGROUND: Aspirin is being used for primary and secondary cardiovascular prevention. It has been proposed that aspirin should be discontinued 5 to 7 days before surgery. However, discontinuation might increase the risk of cardiac and thrombo-embolic co-morbidity. Aspirin also increases the risk of bleeding during and after total knee arthroplasty. This study evaluated if the intra-articular use of a haemostatic matrix (Floseal®) might decrease blood loss in total knee arthroplasty performed under continued aspirin use. MATERIALS AND METHODS: We retrospectively compared matched pairs in two groups (80 patients in each group). Patients in both groups were taking aspirin: one group was managed with conventional haemostasis (with bovie electrocoagulation), while the other group was treated with an intra-articular haemostatic matrix as an adjunct to electrocoagulation. The outcomes compared were haemoglobin and haematocrit levels at days 2 and 4 after surgery as surrogates for blood loss, ...

Ultrasound-guided percutaneous peripheral nerve stimulation for analgesia following total knee arthroplasty: a prospective feasibility study.

Formal rehabilitation programs are often assumed to be required after total knee arthroplasty to optimize patient recovery. Inpatient rehabilitation is a costly rehabilitation option after total knee arthroplasty and, in Australia, is utilized most frequently for privately insured patients. With the exception of comparisons with domiciliary services, no randomized trial has compared inpatient rehabilitation to any outpatient based program. The Hospital Inpatient versus HOme (HIHO) study primarily aims to determine whether 10 days of post-acute inpatient rehabilitation followed by a hybrid home program provides superior recovery of functional mobility on the 6-minute walk test (6MWT) compared to a hybrid home program alone following total knee arthroplasty. Secondarily, the trial aims to determine whether inpatient rehabilitation yields superior recovery in patient-reported function. This is a two-arm parallel randomized controlled trial (RCT), with a third, non-randomized, observational group. One

Both unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) produce satisfactory outcomes in the management of unicompartmental knee osteoarthritis (OA). The purpose of this study is to compare UKA and HTO practice patterns in a large US private payer insurance database. Utilization data for UKA and HTO were captured from the database between 2007 and 2011. Chi square analysis, parametric testing and Poisson regressions were performed where appropriate. Between 2007 and 2011, the compound annual growth rate in utilization of UKA was +4.7%, while that for HTO was −3.9%. Utilization of UKA and HTO were inversely correlated (P = 0.001). UKA utilization is increasing, while HTO utilization is decreasing in the management of OA. More work is required to understand specific indications and outcomes.. ...

Introduction: Diabetes mellitus is an established modifiable risk factor for periprosthetic joint infection (PJI). Haemoglobin A1c (HbA1c) is a glycaemic marker that correlates with diabetic complications and PJI. As diabetes and pre-diabetes are frequently asymptomatic and increasing evidence to suggest linkage with osteoarthritis, it is reasonable to provide HbA1c screening before total knee arthroplasty (TKA). With HbA1c screening, we aimed to investigate the prevalence of undiagnosed dysglycaemia in TKA patients, and whether such practice can reduce PJI. Methods: All TKAs from March 2017 to May 2019 had HbA1c screening were reviewed. Pre-diabetes and diabetes were defined according to the American Diabetes Association. Patients with HbA1c ≥7.5% were referred to an endocrinologist for optimisation before TKA. The PJI rates were compared with histological control with no HbA1c screening. All PJIs were defined according to the Musculoskeletal Infection Society working group in 2011. Results: ...

Many patients report postoperative pain, limited improvement in physical function and poor quality of life (QOL) after knee replacement surgery. Our study uses baseline predictors of change to investigate the QOL of patients with knee osteoarthritis 3-months after knee replacement surgery. A prospective observational study was designed to evaluate patients (n = 132) scheduled for uni-compartmental or total knee replacement surgery who were assessed at baseline (preoperatively) and 3-months after. Physical and mental endpoints based on the component scores of the SF-12 and on the Western Ontario and McMaster Universities Arthritis (WOMAC) index were used to investigate patients QOL. Generalised estimating equation methodology was used to assess patients baseline characteristics (age, sex, education, body mass index (BMI), comorbidity, depressive symptoms, cognitive impairment, smoking/alcohol and type of surgery), the study endpoints and their changes over a 3-month post-surgery period. Stratified

PURPOSE: Current clinical practice guidelines sometimes still recommend stopping aspirin five to seven days before knee arthroplasty surgery. Literature regarding multimodal blood management and continuation of anti-platelet therapy in this type of surgery is scant. The study hypothesis was that knee arthroplasty under low-dose aspirin mono-therapy continuation does not cause more total blood loss than knee arthroplasty performed without aspirin. Blood loss would be measured by haemoglobin (Hb) and haematocrit (HTC) levels drop at day 2 or day 4 for patients who benefit from multimodal bleeding control measures. METHODS: A database of all patients undergoing knee arthroplasty between 2006 and 2014 was analysed. Demographic, surgical and complete blood workup data were collected. A retrospective comparison study analysed both groups in terms of blood loss, by mean calculated blood loss as haemoglobin or haematocrit drop between the preoperative Nadir value and the postoperative day 2 and 4 value. ...

The Oxford medial unicompartmental knee replacement was designed to reproduce normal mobility and forces in the knee, but its detailed effect on the patellofemoral joint has not been studied previously. We have examined the effect on patellofemoral mechanics of the knee by simultaneously measuring patellofemoral kinematics and forces in 11 cadaver knee specimens in a supine leg-extension rig. Comparison was made between the intact normal knee and sequential unicompartmental and total knee replacement. Following medial mobile-bearing unicompartmental replacement in 11 knees, patellofemoral kinematics and forces did not change significantly from those in the intact knee across any measured parameter. In contrast, following posterior cruciate ligament retaining total knee replacement in eight knees, there were significant changes in patellofemoral movement and forces. The Oxford device appears to produce near-normal patellofemoral mechanics, which may partly explain the low incidence of complications with

Acupuncture for the Knee. Acupuncture was applied to patients with total knee arthroplasty starting at day 7 following knee replacement surgery. Acupuncture was administered three times per week until day 21 when the treatment regime was discontinued. Range of motion improved, swelling measurably decreased and pain levels were significantly lower in the acupuncture study group than in the group that did not receive acupuncture therapy. As a result of these findings, the researchers conclude that acupuncture is effective in the post-acute phase of knee rehabilitation following total knee replacement surgery.. This study builds on earlier findings that acupuncture benefits the knee. In other recent research, investigators discovered that acupuncture reduces knee pain and increases range of motion for patients with osteoarthritis. An interesting study, it compared sham acupuncture with modern acupuncture and classical acupuncture techniques. The sham acupuncture, a form of simulated placebo ...

TY - JOUR. T1 - Results of total knee arthroplasty after failed proximal tibial osteotomy for osteoarthritis. AU - Katz, M. M.. AU - Hungerford, D. S.. AU - Krackow, K. A.. AU - Lennox, D. W.. PY - 1987/1/1. Y1 - 1987/1/1. N2 - The cases of twenty-one consecutive patients who had a minimally constrained total knee arthroplasty (six of whom had a cemented and fifteen, an uncemented prosthesis) after a failed proximal tibial osteotomy for osteoarthritis were compared with those of a non-consecutive group of twenty-one patients who had had a primary total knee arthroplasty for osteoarthritis. The groups were matched according to age and sex of the patient, type of prosthesis and fixation, and length of follow-up. At an average length of follow-up of 2.9 years, a good or excellent result was obtained in 81 per cent of the patients who had had a previous osteotomy. At an average length of follow-up of 2.8 years, a good or excellent result was obtained in 100 per cent of the patients who had had a ...

Background: Proximal tibial fractures in elderly patients with osteoporosis or knee osteoarthritis (OA) are challengingcases. In the current study, we present our experience with uncommon acute primary total knee arthroplasty (PTKA)in this patient population.Methods: PTKAs were performed following proximal tibial fractures in 30 consecutive patients over 60 years of agewith osteoporosis or knee OA between 2005 and 2009. Three constrained condylar knees (CCK) and no hinged kneeprosthesis were used. Patients were followed up for 4.5±1.1 years.Results: Patients were discharged after 4.6±1.2 days. The postoperative Tegner activity scale (3.5±1.3) was improvedsignificantly compared to the preoperative scale (2.5±1.2) (P|0.001). The knee flexion range was significantly greaterin the operated side (106±13 degrees) compared to the uninjured knee (120±8 degrees) (P|0.001). The two sectionsof knee society knee score (knee and function section) averaged 90.7±6.5 and 69.6±8.8, respectively. All

Knee osteoarthritis is a highly prevalent condition that can result in disability and reduced quality of life. The evidence suggests that total knee replacement surgery (TKR) is an effective intervention for patients with severe knee problems, but there is also an unmet need for this treatment in the UK. To help understand the reason for this unmet need, the aim of this study was to explore the factors that influence the decision-making process of TKR surgery by synthesising the available evidence from qualitative research on this topic. A meta-synthesis was undertaken. This involved sevens steps: getting started, deciding what is relevant to the initial interest, reading the studies, determining how the studies are related, translating the studies into one another, synthesising translations, and finally, expressing the synthesis. Second-order and third-order interpretations regarding decision-making in TKR surgery were drawn from the literature. Ten qualitative studies were found and are included in

Objective: Examine the efficacy of continuous passive motion (CPM) in postoperative treatment of total knee arthroplasty (TKA) patients, in regards to patient range of motion and length of healing. Introduction: With increasing demands for TKA, it is important to determine the most beneficial therapeutic protocols to improve overall outcomes. CPM is a common adjunct therapy that is utilized in post-operative care of TKA. It is thought to increase the total range of motion (ROM), and function patients obtain following TKA. Great controversy exists in its use, as studies have shown both benefits and no effect in its use. Method: Searches were done in PubMed, Ebsco Host, using the limits: 2004-2014, humans, MEDLINE, academic search premier, Cochrane central register of controlled trials, and CINAHL. This yielded 32 articles in Ebsco Host. Results: Prolonged use of CPM, early flexion CPM and CPM utilized in those with poor ROM showed short-term improvement ROM vs. standard physical therapy (PT) ...

TY - JOUR. T1 - Jig prototype for computer-assisted total knee replacement and its flow simulation. AU - Sulong, Abu Bakar. AU - Arifin, Amir. AU - Harun, Zambri. PY - 2016. Y1 - 2016. N2 - This paper discusses the design and development of a prototype of a knee surgery cutting jig, the jig holder, and the jig injection mold by Rapid Prototyping (RP). The aim of this study is to design a jig and a jig holder that allow surgeons to correctly, precisely, and consistently perform knee replacement surgery. The design concept for the surgery jig and jig holder was selected using the Pugh method with medical-grade 316L stainless steel for material fabrication. A rapid prototype model was built directly from its CAD model in stereo lithography (STL) format by using the Fused Deposition Method (FDM). MasterCAM and Moldflow simulation were performed to generated G-codes and a possibility of jig fabrication using Metal Injection Molding (MIM), respectively. The Moldflow result provided an enhanced ...

TY - JOUR. T1 - Percutaneous neuromodulation pain therapy following knee replacement.. AU - Wanich, Tony. AU - Gelber, Jonathan. AU - Rodeo, Scott. AU - Windsor, Russell. PY - 2011/9. Y1 - 2011/9. N2 - A new device (Deepwave) utilizing percutaneous neuromodulation technology has been developed with preliminary studies demonstrating superior pain inhibition compared with transcutaneous electrical nerve stimulation. We hypothesize that the use of Deepwave is efficacious in reducing the severity of acute pain and opioid use in patients following total knee replacement (TKR) surgery. We conducted a randomized controlled trial on 23 patients who underwent primary TKR. The patients were categorized into two groups--experimental or control group. Following TKR, patients underwent either Deepwave or sham treatments. A Brief Pain Inventory questionnaire and the amount of all pain medications taken were recorded. There was a significant reduction in patients subjective rating of pain and Visual Analog ...

Total knee replacement, also called total knee arthroplasty. Knee surgeon, Dr Matthew Wilkinson in Lenah Valley, South Hobart and Hobart TAS treats knee deformity, knee pain and arthritis.

A case of recurrent hemarthrosis of the knee after a mobile-bearing unicompartmental knee arthroplasty (UKA; Oxford UKA) is described. A 58-year-old man met with a road traffic accident 10 months after UKA. He developed anteromedial pain and hemarthrosis of the knee joint 1 month after the accident, which required multiple aspirations. Physical examination showed no instability. Plain radiograph revealed no signs of loosening. All laboratory data, including bleeding and coagulation times, were within normal limits. Diagnostic arthroscopy demonstrated loosening of the femoral component. Any intraarticular pathology other than nonspecific synovitis was ruled out. The loose femoral component and polyethylene meniscal bearing were revised. Since then, hemarthrosis has not recurred.

AU - Miles, Anthony. AU - Clift, Sally. PY - 2015/9. Y1 - 2015/9. N2 - Background: Finite element (FE) models are frequently used in biomechanics to predict the behaviour of new implant designs.To increase the stability after severe bone loss tibial components with long stems are used in revision total knee replacements(TKR). A clinically reported complication after revision surgery is the occurrence of pain in the stem-end region. The aim ofthis analysis was the development of a validated FE-model of a fully cemented implant and to evaluate the effect of differenttibial stem orientations.Methods: A scanned 4th generation synthetic left tibia (Sawbones) was used to develop the FE-model with a virtually implantedfully cemented tibial component. The 500 N load was applied with medial:lateral compartment ...

Introduction. Unicompartmental arthroplasty of the knee in patients with isolated medial osteoarthritis gives good results, but survival is inferior to that of total knee prosthesis. Knees may fail because positioning of the prosthesis has been suboptimal. The aim of this study was to investigate the influence of the tibial slope on the rate of wear of amedial fixed-bearing unicompartmental knee arthroplasty. Materials and Methods. We simulated wear on a medial fixed-bearing unicompartmental knee prosthesis (Univation) in vitro with a customised, four-station, and servohydraulic knee wear simulator, which exactly reproduced the walking cycle (International Organisation for Standardisation (ISO) 14243-1: 2002(E)). The medial prostheses were inserted with 3 different posterior tibial slopes: 0 degrees, 4 degrees, and 8 degrees (n = 3 in each group). Results. The wear rate decreased significantly between 0 degrees and 4 degrees slope from 10.4 (SD 0.62) mg/million cycles to 3.22 (SD 1.71) ...

Total knee arthroplasty has evolved into a very successful procedure to relieve pain and restore function in the arthritic knee with advanced structural da

In my previous blog, I discussed the need for Total knee replacement (TKR), primarily when the joint needs to be resurfaced and realigned to address knee pain and disability due to angular deformity and the loss of cartilage.. TKR surgery is the most common joint replacement procedure being preformed. During TKR, an arthritic joint is resurfaced, any angular deformity is corrected and the soft tissues, which support the knee, are re-balanced. This reliably relieves pain and allows the patient to become very active again. Osteoarthritis is by far the most common diagnosis that leads to the need for TKR surgery. Although there are many reasons why people develop degenerative osteoarthritis in the knee, the common result is the breakdown of the normal hyaline cartilage that covers the bones that make up the knee: the lower end of the femur bone, the upper end of the tibia and the underneath surface of the knee cap (the patella). The knee is much more than a large hinge joint. In a normal, ...

Methods: Fifty patients undergoing total knee arthroplasty were randomly assigned to receive ultrasound-guided CFNB either with the catheter parallel to the nerve technique (parallel group, n = 25) or with the catheter perpendicular to the nerve technique (perpendicular group, n = 25). Patient-controlled morphine analgesia pumps were available to all the patients after surgery. The time of catheter insertion, failure rates, pain scores, morphine consumption, nausea and vomiting, and maximal degree of knee flexion were recorded. ...

TY - JOUR. T1 - Gigantic Popliteal Synovial Cyst Caused by Wear Particles after Total Knee Arthroplasty. AU - Niki, Yasuo. AU - Matsumoto, Hideo. AU - Otani, Toshiro. AU - Yoshimine, Fumihiro. AU - Inokuchi, Wataru. AU - Morisue, Hikaru. PY - 2003/12. Y1 - 2003/12. N2 - We present a case exhibiting persistent joint effusion and formation of a gigantic popliteal synovial cyst 8 years after total knee joint arthroplasty. Assessment using flow cytometry revealed that both joint and cyst fluid contained abundant macrophage-phagocytosing wear particles. This finding indicates that wear particles participated in formation of the cyst through the communication between the joint cavity and cyst. Intraoperatively, prominent villous synovial proliferation was observed in both the joint and cyst, and delamination failure of the polyethylene insert was identified. Because no evidence of prosthetic loosening was found, only polyethylene insert revision and synovectomy were undertaken, resulting in a ...

Surgical fixation of tibial plateau fracture in elderly patients with open reduction and internal fixation (ORIF) provides inferior outcomes compared with younger patients. Primary total knee arthroplasty (TKA) may be of benefit in elderly patients with a combination of osteoporotic bone and metaphyseal comminution. However, there continues to be conflicting evidence on the use of TKA for primary treatment of tibial plateau fracture. This systematic review was performed to quantify the outcomes and perioperative complication rates of TKA for primary treatment of tibial plateau fracture. A comprehensive search of MEDLINE, Embase, and PubMed databases from inception through March 2018 was performed in accordance with PRISMA guidelines. Two reviewers independently screened papers for inclusion and identified studies featuring perioperative complications and outcomes of primary TKA for tibial plateau fracture. Weighted means and standard deviations are presented for each outcome. Seven articles (105

In patients who have primary unilateral knee arthroplasty, as rehabilitation visits increased there was a direct association to improved interlimb weight-bearing symmetry when squatting to 60 degrees, say authors of an article in American Journal of Physical Medicine & Rehabilitation. For this study, the percentage of body weight placed over both limbs during stand and 30- and 60-degree squats in 38 patients (25 women and 13 men) who had primary unilateral knee arthroplasty was determined. An asymmetry index was used as a marker that could discriminate between patients who perceived at least moderate difficulty with functional tasks and those who perceived only slight or no difficulty with functional activities based on the physical function dimension of the Western Ontario McMaster Universities Osteoarthritis index approximately 1 week after surgery. Stepwise regression was conducted to determine whether clinical characteristics predicted weight-bearing asymmetry at discharge.. At initial visit ...

Unicompartmental knee replacement is a minimally invasive surgery in which only the damaged compartment of the knee is replaced with an implant. It is also called a partial knee replacement. The knee can be divided into three compartments: patellofemoral, the compartment in front of the knee between the knee cap and thigh bone, medial compartment, on the inside portion of the knee, and lateral compartment which is the area on the outside portion of the knee joint.. Traditionally, total knee replacement was commonly indicated for severe osteoarthritis of the knee. In total knee replacement all worn out or damaged surfaces of the knee joint are removed and replaced with new artificial parts. Partial knee replacement is a surgical option if your arthritis is confined to a single compartment of your knee.. Disease Overview. Arthritis is inflammation of a joint causing pain, swelling (inflammation), and stiffness.. Osteoarthritis is the most common form of knee arthritis in which the joint cartilage ...
