The excised fragments of six osteochondritis dissecans lesions of the lateral aspect of the medial femoral condyle were found to be composed of viable hyaline articular cartilage over-lying a totally cellular, metabolically active ossific nucleus, which in turn rested in a bed of fibrocartilage. At the interface between the fibrocartilage and the bone, enchondral ossification was seen histologically and verified by microradiographic evidence of bone formation and resorption. The present authors propose that this classical dissecans lesion is a reparative process and, in most cases, will proceed to complete union of the ossific nucleus with the remainder of the bone of the femoral condyle.
在股骨内侧髁外侧的六个剥脱性骨软骨炎病变的切除碎片中，发现其由覆盖在完全细胞化、代谢活跃的骨化核上的存活透明关节软骨组成，而该骨化核又位于纤维软骨床上。在纤维软骨与骨之间的界面处，组织学上可见软骨内成骨，并通过骨形成和吸收的显微放射学证据得到证实。本文作者提出，这种典型的剥脱性病变是一个修复过程，并且在大多数情况下，将导致骨化核与股骨髁其余部分的骨头完全愈合。
