The Effects of Lesion Size and Location on Subchondral Bone Contact in Experimental Knee Articular Cartilage Defects in a Bovine Model

Current algorithms use size as a primary factor in management of chondral defects of the knee. Although the consequences of subchondral bone contact on femoral condyle articular cartilage defect progression are unknown, the results of this study supplement current algorithms and suggest consideration of defect location, in addition to size, in the management of chondral defects of the knee.
