Clinical outcome after mosaicplasty of knee articular cartilage defects of patellofemoral joint versus tibiofemoral joint

Abstract

Background The purpose was to investigate survival of cartilage repair in the knee joint by osteochondral autograft transfer stratified by location of the lesion; patellofemoral joint (N = 26) versus the medial or lateral femoral condyles (N = 58). Methods For survival analyses, “failure” was defined as the event of a patient reporting a poor Lysholm score (below 65 points) or undergoing a knee replacement procedure. Results The survival distribution was not significantly different between the patellofemoral joint and the tibiofemoral joint groups. Conclusions The current study suggest that similar long-term outcome can be expected after OAT procedures for the patellofemoral or tibiofemoral joint
