对犬膝关节前交叉韧带和内侧副韧带修复术后早期活动、石膏固定6周和石膏固定4周后关节内的变化进行了研究。术后12周处死动物，按Mankin等人描述的系统对骨关节病变进行分级。活动组膝关节骨关节炎改变明显少于固定组和铸型支架组。大多数动物的内侧副韧带愈合良好；然而，早期无限制运动的动物前十字韧带愈合较差。术后制动超过6周会对关节软骨造成相当大的损伤，而早期的无限制运动似乎会影响前十字韧带的愈合。
The intra-articular changes in dog knees were studied following repair of the anterior cruciate and medial collateral ligaments under various postoperative managements: early mobilization, immobilization for 6 weeks in a plaster cast, and limited mobilization for 4 weeks in a cast-brace. The animals were sacrificed at 12 weeks after operation and osteoarthritic changes were graded according to the system described by Mankin et al. The osteoarthritic changes of the knee joints in the mobilized group were significantly less than those in the immobilized and in the cast-brace groups. Medial collateral ligaments were found well healed in most animals; however, anterior cruciate ligaments showed poor healing in the animals treated with early unlimited motion. Postoperative immobilization for more than 6 weeks causes considerable damage to the articular cartilage while early unlimited motion appears to compromise healing of the anterior cruciate ligaments.
