Differences in the Radius of Curvature Between Femoral Condyles: Implications for Osteochondral Allograft Matching

Purpose: Is there a linear correlation between the radius of curvature and anterior-posterior length of a condyle? Would the radius of curvature and anterior-posterior length differ significantly between the medial femoral condyle and the lateral femoral condyle, and would a donor graft from the lateral femoral condyle would be suitable for an medial femoral condyle defect?

Summary: Matching the radius of curvature or anterior-posterior length would not be necessary for potential medial-to-medial or lateral-to-lateral allograft transplants within this patient group. Implantation of Lateral Femoral Condyle donor allograft into an MFC defect is also supported by these findings.
