Modern perceptions and expectations regarding total knee arthroplasty.

It is established that patients and surgeons share different perceptions regarding total knee replacement (TKA). This study's objective was to determine patient perceptions regarding TKA as well as the influence of the various information sources in shaping these perceptions. All patients presenting with knee pain for evaluation of TKA were offered a questionnaire.

Evaluation of limb alignment, component positioning, and function in primary total knee arthroplasty using a pinless navigation technique compared with conventional methods.

The purpose of this study was to examine component positioning, limb alignment, and the early functional range of motion of a pinless image-free computer-assisted navigation system, and compare it to conventional intramedullary component alignment methods. A total of 72 patients underwent cemented total knee arthroplasty. The pinless navigation group consisted of 40 knees in 39 patients, while the conventional group comprised 33 knees in 33 patients.

The effect of retropatellar fat pad excision on patellar tendon contracture and functional outcomes after total knee arthroplasty.

Excision of the fat pad is common in total knee arthroplasty to enhance surgical exposure. However, the effect of this has not been clearly established. A retrospective review of 1055 primary total knee arthroplasties was preformed in 720 patients from 1997 to 1998.

Is there a functional benefit to obtaining high flexion after total knee arthroplasty?

Clinical evidence is lacking to support the functional benefit of high flexion after total knee arthroplasty (TKA). A retrospective review of 511 TKAs in 370 patients was performed. The mean follow-up was 3.
