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.

Level of evidence: Therapeutic study, Level III.
