Anterior knee pain is an important cause of persistent pain after total knee arthroplasty. Lateral retinacular release has been proposed as a procedure to prevent anterior knee pain syndrome, based on the reduction of lateral tension and improving patellar tracking.~However, its effect on anterior knee pain after total knee arthroplasty is not clear when it is not strictly needed to correct maltracking.~The purpose of this trial is to evaluate the effect of systematic lateral retinaculare release on anterior knee pain, peformed during a total knee arthroplasty with patellar resurfacing.
The aim of this study is to assess the effect of systematic lateral retinacular release on anterior knee pain, as well as its impact on the functional and radiological outcomes after total knee arthroplasty with patellar resurfacing.
