The aim of the investigation was to examine and describe the osteoarthrotic changes that chronic, partial or complete lateral ligament compartment (LAT) insufficiency causes to the knee joint. Eleven patients with partial and 10 with complete, isolated rupture of the LAT had a clinical and radiological reexamination of the knee on an average eight years after the injury. In both groups the changes occurred frequently on the lateral side of the knee. The most characteristic findings were osteophytes and subchondral sclerosis of femoral and tibial lateral condyles, tibial eminence and patella, subchondral cysts as well as narrowing of lateral joint space. None of the patients in the group with partial, but 5 (50%) of those with complete insufficiency of the LAT suffered from a clear posttraumatic osteoarthrosis of the injured knee. In complete tears the total extent of these pathological changes per patient was fivefold compared to the patients with partial tear.
该研究的目的是检查并描述慢性、部分或完全外侧韧带隔室（LAT）功能不全对膝关节造成的骨关节炎变化。11例部分LAT断裂患者和10例完全孤立性LAT断裂患者在受伤后平均八年接受了膝关节的临床和放射学复查。两组患者的变化均频繁出现在膝关节外侧。最典型的表现为股骨和胫骨外侧髁、胫骨髁间隆起和髌骨的骨赘形成、软骨下硬化、软骨下囊肿以及外侧关节间隙变窄。部分LAT功能不全组患者中无人出现受伤膝关节明显的创伤后骨关节炎，但完全LAT功能不全组中有5例（50%）出现。在完全撕裂患者中，每位患者这些病理变化的总程度是部分撕裂患者的五倍。
