BACKGROUND Prosthetic impingement due to poor positioning can limit the range of motion of the hip after total hip arthroplasty. In this study, a computer model was used to determine the effects of the positions of the acetabular and femoral components and of varying head-neck ratios on impingement and range of motion. METHODS A three-dimensional generic(More)
A total of 108 consecutive Press-Fit Condylar total knee arthroplasties were performed in 94 patients. All patients had implantation with a cemented posterior cruciate-retaining design, which included resurfacing of the patella. Mean age at surgery was 70 years (range, 35-87 years). Patients were followed for a mean of 9 years (range, 8-10 years) with(More)
One hundred ninety-nine patients who underwent primary total hip arthroplasty and used in hospital pneumatic compression stockings and aspirin as thromboembolic prophylaxis were screened for deep venous thrombosis using duplex ultrasonography on the fourth postoperative day. Of the initial 98 patients, 21 underwent noncemented arthroplasty, maintained(More)
This article describes a technique to aid in removal of polymethylmethacrylate during total hip arthroplasty revision. The technique is a modification of prior windowing techniques and requires no specialized instruments, offers substantial flexibility regarding cement removal and femoral prosthetic choice, and minimizes the amount and duration of stress on(More)
