Cam impingement of the posterior femoral condyle in unicompartmental knee arthroplasty

Abstract

There has been much emphasis on the importance of cam impingement, which is a cause of pain and knee hyperflexion restriction in unicompartmental knee arthroplasty (UKA). This study aimed to correlate cam impingement in the posterior femoral condyle with an alpha-angle showing the severity of the impingement.
