Fixed versus mobile weight-bearing prosthesis in total knee arthroplasty

This report has been verified by one or more authors of the original publication.

300 patients undergoing primary total knee arthroplasty (TKA) were randomized and received either fixed weight-bearing or mobile weight-bearing prostheses to assess the rate of recovery. Despite both groups showing significant improvements in their health, there was no statistical difference in Knee Society Scores, SF-36 scores and patellofemoral joint function scores between the groups at the five-year follow-up assessment. Hence, there was no clear advantage in terms of clinical, radiological, or general health outcomes between fixed or mobile weight-bearing prostheses.
