BACKGROUND Physical activity and regular participation in recreational sports gain importance in patients' lifestyle after knee arthroplasty. Cementless unicompartimental Knee replacement with the Oxford System has been introduced into clinical routine. Currently there is no data reporting on the physical activity, return to sports rate and quality of live after medial cementless Oxford Unicomp...

To assess revision rates after knee arthroplasty we compared cumulative results from world wide clinical studies and arthroplasty registers from the 1960 up to now in one of the largest reviews ever [1]. We found, the overall revision rate at ten years was 6% for total knee arthroplasty (TKA) and17%for unicondylar protheses (UKA). Literature from non-register studies are biased regarding UKA [2...

BACKGROUND Approximately 10% of patients with osteoarthritis (OA) of the knee have unicompartmental OA confined to the patellofemoral joint (PFJ). The main surgical options are total knee replacement (TKR) and PFJ replacement (PFJR). PFJR has a number of advantages over TKR, including being less invasive, preserving the unaffected parts of the knee, allowing faster recovery and better range of ...

Unicondylar knee replacement is a relatively common elective orthopedic procedure but is not often seen in the Emergency Department setting. Familiarity with normal clinical and radiological appearances is difficult to gain. Dislocation of the mobile bearing component "spacer" is a known complication of unicondylar knee replacements, and these patients will initially present to the accident and...

Twenty patients underwent simultaneous bilateral medial unicompartmental knee arthroplasty. Pre-operative hip-knee-ankle alignment and valgus stress radiographs were used to plan the desired post-operative alignment of the limb in accordance with established principles for unicompartmental arthroplasty. In each patient the planned alignment was the same for both knees. Overall, the mean planned...

TECHNIQUE The Lyon Schuss view (an anteroposterior weight-bearing radiograph taken with the knee in 20–30 degrees flexion) offers greater accuracy in determining moderate to severe loss of joint space compared with the standard weight-bearing view with the knee fully extended3,4. This is particularly so in lateral compartment arthritis where the pattern of disease is different, ie the posterior...

Improved prosthetic design and application of strict criteria in selection of patients have resulted in wide use of unicompartmental knee arthroplasty (UKA) in surgical treatment of damaged joints. Here, we review the contemporary indications, outcomes, and complications of procedures such as lateral and medial UKA and total knee arthroplasty (TKA), and compare the severity of these complicatio...

Our aim was to determine the pre-operative sporting profiles of patients undergoing primary joint replacement and to establish if they were able to return to sport after surgery. A postal survey was completed by 2085 patients between one and three years after operation. They had undergone one of five operations, namely total hip replacement, hip resurfacing, total knee replacement, unicompartme...
