Radiolucent lines and component stability in knee arthroplasty. Standard versus fluoroscopically-assisted radiographs. (1/937)

The radiolucent lines and the stability of the components of 66 knee arthroplasties were assessed by six orthopaedic surgeons on conventional anteroposterior and lateral radiographs and on fluoroscopic views which had been taken on the same day. The examiners were blinded as to the patients and clinical results. The interpretation of the radiographs was repeated after five months. On fluoroscopically-assisted radiographs four of the six examiners identified significantly more radiolucent lines for the femoral component (p < 0.05) and one significantly more for the tibial implant. Five examiners rated more femoral components as radiologically loose on fluoroscopically-assisted radiographs (p = 0.0008 to 0.0154), but none did so for the tibial components. The mean intra- and interobserver kappa values were higher for fluoroscopically-assisted radiographs for both components. We have shown that fluoroscopically-assisted radiographs allow more reproducible, and therefore reliable, detection of radiolucent lines in total knee arthroplasty. Assessment of the stability of the components is significantly influenced by the radiological technique used. Conventional radiographs are not adequate for evaluation of the stability of total knee arthroplasty and should be replaced by fluoroscopically-assisted films.  (+info)

Manipulation of total knee replacements. Is the flexion gained retained? (2/937)

As part of a prospective study of 476 total knee replacements (TKR), we evaluated the use of manipulation under anaesthesia in 47 knees. Manipulation was considered when intensive physiotherapy failed to increase flexion to more than 80 degrees. The mean time from arthroplasty to manipulation was 11.3 weeks (median 9, range 2 to 41). The mean active flexion before manipulation was 62 degrees (35 to 80). One year later the mean gain was 33 degrees (Wilcoxon signed-rank test, range -5 to 70, 95% CI 28.5 to 38.5). Definite sustained gains in flexion were achieved even when manipulation was performed four or more months after arthroplasty (paired t-test, p < 0.01, CI 8.4 to 31.4). A further 21 patients who met our criteria for manipulation declined the procedure. Despite continued physiotherapy, there was no significant increase in flexion in their knees. Six weeks to one year after TKR, the mean change was 3.1 degrees (paired t-test, p = 0.23, CI -8.1 to +2).  (+info)

The tourniquet in total knee arthroplasty. A prospective, randomised study. (3/937)

We assessed the influence of the use of a tourniquet in total knee arthroplasty in a prospective, randomised study. After satisfying exclusion criteria, we divided 77 patients into two groups, one to undergo surgery with a tourniquet and one without. Both groups were well matched. The mean change in knee flexion in the group that had surgery without a tourniquet was significantly better at one week (p = 0.03) than in the other group, but movement was similar at six weeks and at four months. There was no significant difference in the surgical time, postoperative pain, need for analgesia, the volume collected in the drains, postoperative swelling, and the incidence of wound complications or of deep-venous thrombosis. We conclude that the use of a tourniquet is safe and that current practice can be continued.  (+info)

Primary hip and knee replacement surgery: Ontario criteria for case selection and surgical priority. (4/937)

OBJECTIVES: To develop, from simple clinical factors, criteria to identify appropriate patients for referral to a surgeon for consideration for arthroplasty, and to rank them in the queue once surgery is agreed. DESIGN: Delphi process, with a panel including orthopaedic surgeons, rheumatologists, general practitioners, epidemiologists, and physiotherapists, who rated 120 case scenarios for appropriateness and 42 for waiting list priority. Scenarios incorporated combinations of relevant clinical factors. It was assumed that queues should be organised not simply by chronology but by clinical and social impact of delayed surgery. The panel focused on information obtained from clinical histories, to ensure the utility of the guidelines in practice. Relevant high quality research evidence was limited. SETTING: Ontario, Canada. MAIN MEASURES: Appropriateness ratings on a 7-point scale, and urgency rankings on a 4-point scale keyed to specific waiting times. RESULTS: Despite incomplete evidence panellists agreed on ratings in 92.5% of appropriateness and 73.8% of urgency scenarios versus 15% and 18% agreement expected by chance, respectively. Statistically validated algorithms in decision tree form, which should permit rapid estimation of urgency or appropriateness in practice, were compiled by recursive partitioning. Rating patterns and algorithms were also used to make brief written guidelines on how clinical factors affect appropriateness and urgency of surgery. A summary score was provided for each case scenario; scenarios could then be matched to chart audit results, with scoring for quality management. CONCLUSIONS: These algorithms and criteria can be used by managers or practitioners to assess appropriateness of referral for hip or knee replacement and relative rankings of patients in the queue for surgery.  (+info)

Limb salvage surgery in bone tumour with modular endoprosthesis. (5/937)

Thirty-three patients with bone tumours were treated by resection of the growth and reconstruction with a Kotz modular endoprosthesis. The average follow-up was for 50 months, ranging from 14 to 79 months. At the last review, 12 patients (36%) had died due to the tumour and 9 others (27%) had metastases. All 4 patients with proximal tibial reconstruction had poor functional results, due to an extension lag or to knee stiffness. Four of the six tumours of the proximal femur were complicated by local recurrence or dislocation of the hip, and had poor or fair functional results. Of the patients with distal femoral reconstruction, 17 out of 22 had excellent or good functional results. Reconstruction with a modular prosthesis after resection of a tumour gives excellent or good functional results in more than three-fourths of the cases of distal femur reconstruction, but it should be used with caution in the proximal tibia and proximal femur.  (+info)

Soft tissue cover for the exposed knee prosthesis. (6/937)

This study assess the use of muscle flaps to cover exposed knee prostheses and emphasises the need for early plastic surgery consultation. In five of the six patients studied the wound was successfully covered and the knee prosthesis salvaged with a reasonable functional outcome.  (+info)

Survivorship analysis of the "Performance" total knee replacement--7-year follow-up. (7/937)

We present the results of a prospective study in which 32 "Performance" total knee replacements were implanted with a mean follow-up period of 6.5 years. Survival analysis showed 89% survival at 7 years. Of those knees that survived to follow-up 80% were pain free or had mild pain when climbing stairs and only 1 knee was unable to flex beyond 100 degrees. Eighty-six percent of patients were able to walk unlimited distances and all knees had a statistically significant improvement in the knee evaluation scores at follow-up. There was no evidence of loosening or migration in the surviving knees.  (+info)

The results at ten years of the Insall-Burstein II total knee replacement. Clinical, radiological and survivorship studies. (8/937)

We reviewed the outcome of 146 Insall-Burstein II total knee replacements carried out in 121 patients over a period of nearly four years in a general orthopaedic unit. At a mean follow-up of ten years, 94 knees in 78 patients were available for review. Six patients (7 knees) were lost to follow-up and 37 (45 knees) had died. The clinical outcome using the scoring system of the Hospital for Special Surgery (HSS) was excellent or good in 79% of patients, fair in 14% and poor in 7%. The mean preoperative HSS score was 31, improving to 79 at the latest review. Using the newer rating system of the Knee Society, the mean score at ten years was 87 and the mean functional score 56. The arc of flexion improved from a mean preoperative value of 88 degrees to 100 degrees. The 18 patients who had had a previous high tibial osteotomy were analysed separately and were found to have benefited equally from the operation. Nine prostheses were revised, giving a cumulative survival rate of 92.3% at ten years. Radiological evaluation of 104 radiographs showed radiolucent lines around ten tibial components, none of which required revision. Anterior knee pain was a significant problem.  (+info)

Simultaneous in vitro measurement of patellofemoral kinematics and forces following Oxford medial unicompartmental knee...Simultaneous in vitro measurement of patellofemoral kinematics and forces following Oxford medial unicompartmental knee...
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

As part of the step-wise validation of a new prosthesis (TMK), we previously published the 1 year results of a randomised controlled trial in patients undergoing bilateral knee replacement [Price A., Rees J., Beard D., Juszczak E. et al. A mobile-bearing total knee prosthesis compared with a fixed-bearing prosthesis. JBJS B 2003;85-B-1:62-7.]. Forty patients had the new mobile-bearing prosthesis implanted in one knee and an established fixed-bearing device in the other (AGC). We now report the 3 year status of these patients and, in addition, review a separate multi-centre cohort of 172 patients who had undergone unilateral arthroplasty with the TMK. No significant differences were found in outcome (American Knee Society Score and Oxford Knee Score) between the two prostheses. The greater incidence of clicking in the mobile-bearing knee, reported in the previous review, persisted (TMK=48%, AGC=30%). The presence of this mechanical noise was found to have no relationship with outcome in either of the
Bicompartmental knee arthroplasty of the patellofemoral and medial compartments. - Surgical Intervention Trials UnitBicompartmental knee arthroplasty of the patellofemoral and medial compartments. - Surgical Intervention Trials Unit
PURPOSE: Studies have shown that after total knee arthroplasty neither normal biomechanics nor function is obtained. Selective resurfacing of diseased compartments could be a solution. A narrative review of the available literature on bicompartmental arthroplasty is presented. METHODS: A literature review of all peer reviewed published articles on bicompartmental arthroplasty of the knee was performed. Bicompartmental arthroplasty is by definition the replacement of the tibiofemoral and the patellofemoral joint. It can be performed with a modular unlinked or a monolithic femoral component. RESULTS: Bicompartmental arthroplasty performed with modular components obtains good to excellent results at ± 10 years follow-up. Function and biomechanics are superior to total knee arthroplasty. Modern monolithic femoral components are reported to give early failure and high revision rates and should be avoided. CONCLUSION: Modular bicompartmental arthroplasty is an excellent alternative to treat bicompartmental

Background - Limited previous findings have detailed biomechanical advantages following implantation with mobile bearing (MB) prostheses after total knee replacement (TKR) surgery during walking. The aim of this study was to compare three dimensional spatiotemporal, kinematic, and kinetic parameters during walking to examine whether MBs offer functional advantages over fixed bearing (FB) designs.. Methods - Sixteen patients undergoing primary unilateral TKR surgery were randomised to receive either a FB (n = 8) or MB (n = 8) total knee prosthesis. Eight age and gender matched controls underwent the same protocol on one occasion. A 12 camera Vicon system integrated with four force plates was used. Patients were tested pre-surgery and nine months post-surgery.. Results - No significant differences between FB and MB groups were found at any time point in the spatiotemporal parameters. The MB group was found to have a significantly reduced frontal plane knee range of motion (ROM) at pre-surgery than ...

Satisfactory selection criteria are essential for the successful outcome of unicompartmental knee arthroplasty (UCA). We report the frequency of revision of the Oxford medial unicompartmental arthroplasty in knees previously treated for anteromedial osteoarthritis by high tibial osteotomy (HTO). The combined results from three sources were used to allow statistical analysis of this uncommon subgroup. In the combined series of 631 knees (507 patients) which had medial unicompartmental replacement, 613 were primary procedures and 18 were for a failed HTO. The mean follow-up times of the two groups were similar (5.8 years and 5.4 years, respectively). At review, 19 (3.1%) of the primary procedures and five (27.8%) of those undertaken for a failed HTO had been revised to total knee replacement. Survival analysis revealed the ten-year cumulative survivals to be 96% and 66%, respectively. The log-rank comparison of these survivals revealed a highly significant difference (p | 0.0001). We recommend that the
Increase in the Tibial Slope Reduces Wear after Medial Unicompartmental Fixed-Bearing Arthroplasty of the KneeIncrease in the Tibial Slope Reduces Wear after Medial Unicompartmental Fixed-Bearing Arthroplasty of the Knee
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) ...

With medial unicompartmental osteoarthritis (OA) there is occasionally a full-thickness ulcer of the cartilage on the medial side of the lateral femoral condyle. It is not clear whether this should be considered a contraindication to unicompartmental knee replacement (UKR). The aim of this study was to determine why these ulcers occur, and whether they compromise the outcome of UKR. Case studies of knees with medial OA suggest that cartilage lesions on the medial side of the lateral condyle are caused by impingement on the lateral tibial spine as a result of the varus deformity and tibial subluxation. Following UKR the varus and the subluxation are corrected, so that impingement is prevented and the damaged part of the lateral femoral condyle is not transmitting load. An illustrative case report is presented. Out of 769 knees with OA of the medial compartment treated with the Oxford UKR, 59 (7.7%) had partial-thickness cartilage loss and 20 (2.6%) had a full-thickness cartilage deficit on the medial

These total knee prostheses permit flexion and extension and allow for a limited rotation. The linked total knee prostheses, however, prevent movements to both sides (abduction and adduction) of the knee joint. That is their purpose: to provide the total knee with intrinsic side stability.. The limited amount of rotation, that these prostheses allow, improves gait and decreases stresses on the bone -skeleton interface created by walk and other activities. Thus, in contrast to the old true hinged total knees, the linked total knee prostheses have lover rates of complications. (more…). Read More ...

A radiological review was carried out to establish if dislocation was related to surgical technique. The postoperative radiographs of 46 lateral unicompartmental arthroplasties were analysed. Five variables which related to the position and alignment of the components were measured. Dislocations occurred in six knees. Only one of the five variables, the proximal tibial varus angle, had a statistically significant relationship to dislocation. This variable quantifies the height of the lateral joint line. The mean proximal tibial varus angle for knees the bearings of which had dislocated was 9 degrees and for those which had not it was 5 degrees. In both groups it was greater than would be expected in the normal knee (3 degrees). Our study suggests that a high proximal tibial varus angle is associated with dislocation. The surgical technique should be modified to

Total Knee Prosthesis after Knee Joint Distraction Treatment | JSSRTotal Knee Prosthesis after Knee Joint Distraction Treatment | JSSR
Background and purpose: During knee joint distraction (KJD) treatment, using an external fixation-frame, pin-tract infections frequently occur. These local skin infections, although treated successfully with oral antibiotics, might lead to latent infections. This raises concern about subsequent placement of a total knee prosthesis (TKP). This study evaluates the first five cases in which patients had to be treated with TKO after KJD failure.. Patients and methods: An overall survival analysis of the first 26 patients treated with KJD revealed five failures, because of declining efficacy over time. These patients were treated with TKP. Complications of these TKPs are described and all cases were compared with age and gender matched primary-TKP-controls. WOMAC and VAS pain scores were assessed before and after TKP treatment.. Results: The mean survival time of the five KJD before TKP was 61 ± 15 months (range 45-84 months). No peri-operative complications were registered and none of the patients ...

Histology of the bone-cement interface in retrieved Oxford unicompartmental knee replacements - CoxaProHistology of the bone-cement interface in retrieved Oxford unicompartmental knee replacements - CoxaPro
Pre-revision radiographs showed the presence of both full and partial RLL. On contact radiographs of 5 mm thick sections of the interface the total percentage of radiolucency ranged from 0 to 90% between patients. There was no consistent pattern for the distribution of radiolucency. Histological assessment demonstrated that under every tibial component there were areas where there was direct contact and interdigitation between bone and cement. The amount of direct bone-cement contact was between 19% and 95% of the tibial tray surface area. The remaining tissue was mainly fibrocartilage but there was also fibrous tissue. The presence of radiolucency was strongly inversely correlated with the percentage of cement-bone contact ...
Effect of femoral to tibial varus mismatch on the contact area of unicondylar knee prostheses - Zurich Open Repository and...Effect of femoral to tibial varus mismatch on the contact area of unicondylar knee prostheses - Zurich Open Repository and...
In unicondylar knee prostheses, the relative angle and congruency of the femoral against the tibial component is not mechanically constrained and may vary with the surgical implantation technique. The contact area between both components was measured with increasing varus (0-20 degrees) and flexion angles (-20 degrees to 90 degrees) in five prosthesis models in the laboratory. The contact area varied with the relative position of the components and was critically reduced up to 70% at a varus range between ,5 degrees and ,25 degrees. The importance of relative malpositioning of the femoral and tibial components may be underestimated and reduces the contact area of unicondylar prostheses decisively, independent from the limb axis. This increases local pressure and may thus importantly contribute to increased wear and early loosening. ...

A knee prosthesis comprises (i) a femoral component having a medial condyle and a lateral condyle and (ii) a tibial component. The rolling surface of the medial condyle is part-spherical and the tibial component has a complementary part-spherical depression in its upper surface to receive the medial condyle. The bearing surface of the lateral condyle includes a posterior part which has a curvature in a substantially sagittal plane about a first point on a transverse axis that passes through the center of curvature of the rolling surface of the medial condyle and an anterior part which has a curvature in the same plane about a point that lies on a second transverse axis parallel to, and anterior to, the first transverse axis. The tibial component has an arcuate groove to receive the lateral condyle and to permit, in flexion of the knee after implantation, limited anterior/posterior movement of the lateral side of the tibia relative to the femur. In flexion of the knee the posterior part of the rolling

What Makes Axis Knee System unique? - News & Events - Orthopaedic International, Inc.What Makes Axis Knee System unique? - News & Events - Orthopaedic International, Inc.
There are numerous Total Knee Arthroplasty systems in the market with each system having different sets of instrumentation and different techniques that accompany each set. There are several things that make the surgical technique of Axis Knee System unique.. The goal of any Total Knee Arthroplasty surgery is to align the lower limb. This alignment is guided by three points namely the center of the femoral head, the center of the knee and the center of the ankle. It is relatively easy to get the center of the knee and the center of the ankle because they are accessible during surgery. The femoral head is deep in the hip and is outside the surgical field. Most systems will use guide rods inserted in the femoral canal and reference off of that, getting an average value in degrees that they assume will point to the femoral head. Some use preoperative x-rays to locate the femoral head and put a physical marker that the surgeon can palpate during surgery. More modern systems use expensive computer ...

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

We did an in vivo fluoroscopic study comparing the sagittal plane kinematics of mobile-bearing and fixed-bearing total knee arthroplasties in a unique group of patients. These patients were part of a larger bilateral randomized controlled outcome trial with each patient having received both types of total knee arthroplasties. Invited patients did three exercises with each of their different knee replacements; extension against gravity, flexion against gravity, and a step-up. These exercises were recorded using video fluoroscopy, and a series of still digital images over the flexion range were retrieved. The relationship of patella tendon angle to knee flexion angle for each patient was derived. The patella tendon angle to knee flexion angle of the mobile-bearing knee behaved in a linear manner more closely replicating the normal knee, whereas the fixed-bearing knee behaved in a nonlinear, more variable manner. This pattern of results was similar for all three exercises with each patient having one knee
Early failure of unicompartmental knee arthroplasty leading to revision. - Semantic ScholarEarly failure of unicompartmental knee arthroplasty leading to revision. - Semantic Scholar
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.

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 ...

Revision Total Knee Arthroplasty: Exposure and Component RemovalRevision Total Knee Arthroplasty: Exposure and Component Removal
|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

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 ...

Backgroud: There is uncertainty around whether to use unicompartmental knee replacement (UKR) or total knee replacement (TKR) for individuals with osteoarthritis confined to a single compartment of the knee. We aimed to emulate the design of the Total or Partial Knee Arthroplasty Trial (TOPKAT) using routinely collected data to assess whether the efficacy results reported in the trial translate into effectiveness in routine practice, and to assess comparative safety.. Methods: We did a population-based network study using data from four US and one UK health-care database, part of the Observational Health Data Sciences and Informatics network. The inclusion criteria were the same as those for TOPKAT; briefly, we identified patients aged at least 40 years with osteoarthritis who had undergone UKR or TKR and who had available data for at least one year prior to surgery. Patients were excluded if they had evidence of previous ...

N2 - Obesity has a negative influence on surgical times in total knee arthroplasty (TKA). Our purpose in this multicenter study was to compare surgical times between high- (HV) and nonhigh-volume (NHV) surgeons and clarify the important factors affecting longer surgical times in primary TKA for obese patients. A total of 798 knees, average age 75.1 years, were enrolled. All TKAs were done using the same measured resection technique by 25 surgeons at 12 facilities and were divided into three groups based on body mass index (kg/m 2 ) of the patients (Group A: ,24.9, Group B: 25-29.9, Group C: ≥30).

Excessive polyethylene wear is recognized as one of the most important factors affecting the durability of total knee arthroplasty; however, bearing surface wear is a multifactorial problem. The purpose of this study was to identify factors for polyethylene wear and failure in primary posterior cruciate-retaining (PCR) total knee arthroplasty (TKA) in two disparate cohorts (American and Japanese). Seventy-three total knee arthroplasty operations were performed on 48 Japanese patients, and 76 on 63 American patients with noninflammatory arthritides. All patients were evaluated clinically and radiographically using a total joint arthroplasty database. Age, weight, diagnosis, Knee Society patient category, prosthesis size, insert thickness, alignment, polyethylene wear, osteolysis, Knee Society knee score, Knee Society pain score, and radiographic and clinical survivorship were evaluated. Seventy-three Japanese TKAs were followed for a mean of 6.6 years (range, 2.0-10.6). Three (4.1%) Japanese ...

The aim of this study was to assess the outcome after IDCR when combined with chronic antibiotic suppression. We also evaluated survivorship free from subsequent infection, removal of the components, and death, as well as the risk factors for failure. Patients and Methods: This was a single-centre retrospective review of 134 infected primary TKAs that were treated with IDCR. Infections within four weeks of the procedure were defined as acute postoperative infections, and those occurring more than four weeks after the ...
The Effect of Sagittal Femoral Bowing on the Femoral Component Position in Total Knee ArthroplastyThe Effect of Sagittal Femoral Bowing on the Femoral Component Position in Total Knee Arthroplasty
Background: In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment ofthe femoral component in total knee arthroplasty (TKA).Methods: There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittalfemoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cortical line(DACL) were measured. Finally, the correlation of component alignment and SFB was examined.Results: Mean SFB was 7±2.7 degrees. The component was in flexion position in relation to mechanical axis and DACL as8.4±2.9 degrees and 1.7±0.9 degrees, respectively. The flexion alignment of the component was significantly correlatedwith SFB.Conclusion: Mechanical alignment of the limb in both coronal and sagittal axes should be preserved in TKA. SFB cansignificantly increased the flexion alignment of the femoral component.

TY - JOUR. T1 - Current strategies in anesthesia and analgesia for total knee arthroplasty. AU - Moucha, Calin Stefan. AU - Weiser, Mitchell C.. AU - Levin, Emily J.. PY - 2016/2/1. Y1 - 2016/2/1. N2 - Total knee arthroplasty is associated with substantial postoperative pain that may impair mobility, reduce the ability to participate in rehabilitation, lead to chronic pain, and reduce patient satisfaction. Traditional general anesthesia with postoperative epidural and patient-controlled opioid analgesia is associated with an undesirable adverse-effect profile, including postoperative nausea and vomiting, hypotension, urinary retention, respiratory depression, delirium, and an increased infection rate. Multimodal anesthesia - incorporating elements of preemptive analgesia, neuraxial perioperative anesthesia, peripheral nerve blockade, periarticular injections, and multimodal oral opioid and nonopioid medications during the perioperative and postoperative periods - can provide superior pain ...

Femur4
  • The tibial component has an arcuate groove to receive the lateral condyle and to permit, in flexion of the knee after implantation, limited anterior/posterior movement of the lateral side of the tibia relative to the femur. (justia.com)
  • In this way anterior/posterior movement of the lateral side of the tibia relative to the femur is hindered in the straightened condition of the knee. (justia.com)
  • The natural knee joint is complemented by two collateral ligaments, one on the lateral side of the joint and the other on the medial side thereof, each attached both to the tibia and to the femur. (justia.com)
  • The points of attachment of the collateral ligaments to the femur are approximately on the axis of the arc along which the other end of the tibia moves and the knee flexes. (justia.com)
Fixation5
  • During knee joint distraction (KJD) treatment, using an external fixation-frame, pin-tract infections frequently occur. (peertechz.com)
  • The subject's bone stock is compromised by disease or infection and cannot provide adequate support and/or fixation to the prosthesis. (clinicaltrials.gov)
  • Excessive motion at the bone-prosthesis interface is known to inhibit bone ingrowth and thereby cause failure of the fixation. (booksc.org)
  • In the present study, relative displacements between the host bone and the tibia1 component of total knee implants were evaluated, and the effect of the method on the immediate post-operative fixation was assessed using a three-dimensional friction-contact finite element model of the tibia-prosthesis unit and ADINA. (booksc.org)
  • However, regardless of the nature of the initial fixation, when load is transferred across an interface between materials with very dissimilar moduli, as is the case in a bone-metal prosthesis interface, relative displacement necessarily occurs at the interface. (booksc.org)
Joint Prostheses2
  • Often, surgical revision is required to address the significant health issues associated with defects in knee and other joint prostheses. (njatty.com)

Implants1
Femoral component1
  • A knee prosthesis comprises (i) a femoral component having a medial condyle and a lateral condyle and (ii) a tibial component. (justia.com)
Implantation1
Unicompartmental knee prosthesis1
  • 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). (uni-muenchen.de)
Posterior3
  • The posterior cruciate ligament may also be removed depending on the prosthesis used. (hirslanden.ch)
  • In flexion of the knee the posterior part of the rolling surface of the lateral condyle is received in this arcuate groove but, as the knee straightens and approaches its straightened condition, the anterior part of this rolling surface bears on the anterior end of the groove and thereby forces the lateral side of the tibial component to move anteriorly relative to the lateral condyle by a camming action. (justia.com)
  • The Rotating Platform device configuration is indicated for use in knees whose anterior and posterior cruciate ligaments are absent or are in such condition as to justify their sacrifice. (depuysynthes.com)
Surgery3
  • The total knee surgery is turned into something akin to an instrumented landing of an aircraft. (orthoped.org)
  • In practice, the computer systems used just now in total knee surgery are more simple. (orthoped.org)
  • The porous coated Keeled and Non Keeled M.B.T. (Mobile Bearing Tibial) Tray configurations of the LCS Total Knee System are indicated for noncemented use in skeletally mature individuals undergoing primary surgery for reconstructing knees damaged as a result of noninflammatory degenerative joint disease (NIDJD) or either of its composite diagnoses of osteoarthritis and post-traumatic arthritis pathologies.

  • During your hospital stay, the fit of the prosthesis is checked again using x-ray images and you will be instructed about exercises to regain mobility. (hirslanden.ch)
  • The prototype black metal knee joint may look like some kind of automobile part, but the biomedical engineer hopes the simple device will give the gift of mobility to untold numbers of people in developing countries who have lost a leg to amputation. (reddeeradvocate.com)
  • Knee arthritis refers to damage of the joint surface leading to progressive loss of normal joint function leading to pain, stiffness and limitation of mobility. (eliteorthoindia.com)
