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.
Quadriceps Tendon Rupture and Contralateral Patella Tendon Avulsion Post Primary Bilateral Total Knee Arthroplasty: A Case Report
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 ...
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. ...
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.
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
MODEL RELEASED. Total knee replacement surgery. Image 11 of 14. Close-up of surgeons performing an operation to completely replace the worn knee joint (centre) of a patient suffering from severe osteoarthritis of the knee. Osteoarthritis causes the cartilage surface of the bones to wear down. This means that the bones of the joint rub against each other causing them to become rough and painful. This surgery is replacing the worn knee with a Zimmer Nexgen Legacy Posterior Stabilized (LPS) prosthetic knee (silver, centre). There isnt usually this much blood during surgical procedures but the patient has arterial disease, so the usual tourniquet couldnt be used to stop the bleeding. - Stock Image C001/4650

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.
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, ...
The purpose of this study is to compare two different surgical approaches for total knee replacement surgery.

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

By the end of 1995,1,135 of 14,772 primary unicompartmental knee arthroplasties UKA for localized, mainly medial arthrosis had been revised. The Marmor/Richards and St. Georg sledge/Endo-Link prostheses were used in 65%. Mean age...
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. ...

Patient had a unicompartmental knee arthroplasty a couple years ago. Now we are doing a total knee revision arthroplasty (femur, tibia and patella). D
Recently, unicondylar knee arthroplasty (UKA) has seen a resurgence in clinical popularity, due to its increased success rate, improvement in implant designs, and more efficient surgical techniques. However, it continues to be a more technically demanding procedure and less forgiving compared to TKA [14,16-19]. The early reported failures due to the malalignment errors during surgery remain areas of concern clinically and experimentally [41-44,46]. In addition, the difference in the compliance between the UKA implant materials (metal-polymer) and the soft tissues in the un-operated comparted could also affect the load distribution on the knee joint. Advancement in medical technology and improvement in surgical techniques, such as computer navigation and robotic guidance, have allowed significant improvement in the accuracy of UKA compared to its preoperative plan. However, the real impact of the improved implant placement accuracy has yet to be demonstrated. Therefore, a more quantitative assessment of
A partial knee replacement is surgery to replace only one part of a damaged knee. Unicompartmental knee arthroplasty is performed by Dr. Elzaim in Mission, Edinburg and McAllen.

In agreement with previous observations,9 there were no differences in perioperative time course of plasma concentration of TNF-α and IL-10 between groups (table 2), although a small postoperative increase in IL-10 after USB has been reported in TKR patients.14 However, in accordance with previous studies using this ex vivo model of whole blood cultures,15,16 we found that the anesthetic-surgical procedure decreases lipopolysaccharide-stimulated cytokine release. This effect might be driven by the sustained IL-6 secretion,9 which down-regulates the proinflammatory response by inhibiting the expression of TNF-α and IL-1β17 and results in a shift of the Th1/Th2 ratio toward a Th2-dominated cytokine pattern.1 As previously reported, reinfusion of leukodepleted USB did not modify perioperative cytokine levels in TKR patients.9 In addition, from postoperative days 1 through 7, we found that reinfusion of USB did not modify lipopolysaccharide-stimulated cytokine release by peripheral mononuclear ...
Knee replacement is considered an important achievement in orthopaedic surgery. The development of the total knee replacement procedure began back in 1860 when a German surgeon surgically implanted the first primitive hinge joint made of ivory, giving the patient a greater quality of life and restoring the function of the knee joint. The introduction of the acrylic Walldius hinge joint in 1951 was followed by the development of the knee arthroplasty in 1960 based on the John Charnleys cemented metal-on-polyethylene total hip replacement. The surgical outcome has been improved due to changes in the designs of the implants and the development of new and better instrumentation. The modern arthroplasty is a procedure with long-lasting results and functional improvement. About 3.48 million total knee replacements have been estimated to be performed annually in the USA by 2030. Nowadays, it is considered a safe surgical procedure with positive patients outcomes. Its main purpose is to improve the ...

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 ...
