Eleven dogs underwent transection of the anterior cruciate ligament at the femoral origin of the stifle (knee) joint. The anterior cruciate ligaments were repaired in a conventional manner and augmented by transferring the medial one-third of the patellar tendon and inserting it into the lateral femoral condyle. The repairs were evaluated either 4 or 8 months postoperatively. All repaired and augmented anterior cruciate legaments in this series healed satisfactorily to provide clinical and functional stability to the knee joints. Instron testing of the repaired and augmented anterior cruciate ligaments showed maximum strength at 4 months of 46.2 +/- 10.9 kgf and at 8 months of 64.3 +/- 14.3 kgf as compared to the control of 122.7 +/- 11.6 kgf. Histologic evaluation showed that by 8 months the repaired and augmented anterior cruciate ligaments had healed by bony ingrowth. Thus, interstitial failure occurred during Instron testing. The transferred patellar tendon provided additonal blood supply, splinted the anterior cruciate ligament to allow healing, and increased the strength of the repaired complex.
11只狗在膝关节股骨髁间窝处进行前交叉韧带切断术。前交叉韧带采用传统方式修复，并通过转移髌腱内侧三分之一并将其插入股骨外侧髁进行加强。术后4个月或8个月对修复情况进行评估。该系列中所有修复并加强的前交叉韧带均愈合良好，为膝关节提供了临床和功能稳定性。对修复并加强的前交叉韧带进行英斯特朗测试（材料试验机测试），结果显示4个月时最大强度为46.2±10.9千克力，8个月时为64.3±14.3千克力，而对照组为122.7±11.6千克力。组织学评估显示，到8个月时，修复并加强的前交叉韧带已通过骨长入实现愈合。因此，在英斯特朗测试期间发生了间质破坏。转移的髌腱提供了额外的血液供应，固定了前交叉韧带以促进愈合，并增加了修复复合体的强度。
