收集46例骨关节炎单室关节置换术中切除的胫骨内侧平台并拍照。所有关节前交叉韧带完整。在每个病例中，软骨和骨侵蚀都集中在平台前部，后部软骨完好无损。损伤部位和十字韧带的完好状态一起解释了为什么内翻畸形只在伸直膝关节中观察到，以及为什么畸形是可以矫正的，而不是固定的。前交叉韧带的破坏可使糜烂向后方延伸，产生固定内翻畸形并导致外侧筋室退变。前内侧骨关节炎是一种独特的临床病理实体；其放射学特征使其能够从侧位x线片诊断；其解剖特点使其适合于单室关节置换术治疗。
Medial tibial plateaux excised during 46 unicompartmental arthroplasties for osteoarthritis were collected and photographed. The anterior cruciate ligament was intact in all joints. In every case the cartilage and bone erosion was centred anteriorly on the plateau and the posterior cartilage was intact. The site of the lesion and the intact state of the cruciate ligaments taken together explain why varus deformity was observed only in the extended knee, and why the deformity was correctable and had not become fixed.Failure of the anterior cruciate ligament may allow the erosion to extend posteriorly, producing fixed varus deformity and leading to degeneration of the lateral compartment.Anteromedial osteoarthritis is a distinct clinicopathological entity; its radiographic features enable it to be diagnosed from lateral radiographs; its anatomical features render it suitable for treatment by unicompartmental arthroplasty.
