Contralateral Lateral Femoral Condyle Allografts Provide anAcceptable Surface Match for Simulated Classic Osteochondritis Dissecans Lesionsof the Medial Femoral Condyle

摘要

Objectives:The purpose of this study was to determine whether contralateral lateral femoral condyle (LFC) allografts can provide an acceptable surface topography match for classic osteochondritis dessicans (OCD) lesions of the medial femoral condyle (MFC). Achievement of an acceptable donor-recipient articular surface match (1 mm deviation) has been associated with physiological joint stresses and predictably positive clinical outcomes. It was hypothesized that LFC and MFC allografts would show no differences in step-off height or surface deviation in all four quadrants of the graft.
