32 patients with old anterior cruciate ligament injuries were operated on with patellar tendon-prepatellar tissue-quadriceps tendon graft over the top without and with augmentation (Kennedy-LAD). The anteroposterior (AP) laxity was assessed preoperatively, and at 6, 12, and 24 months after the operation with roentgen stereophotogrammetry. 6 months postoperatively the instability had decreased 5.4 mm in the nonaugmented and 1.9 mm in the augmented group, but not to normal values. During the following 18 months the AP laxity increased and returned to the preoperative level. At 2 years, 28 of the 32 patients were considered good or excellent, according to the Lysholm score. There was a lack of correlation between AP laxity and functional tests.
32例陈旧性前交叉韧带损伤患者接受了髌腱-髌前组织-股四头肌肌腱经骨隧道双束重建术，其中部分患者采用Kennedy韧带增强装置（Kennedy-LAD）进行加强。术前及术后6、12和24个月采用X线立体摄影测量法评估前后向（AP）松弛度。术后6个月，未增强组的不稳定度降低了5.4 mm，增强组降低了1.9 mm，但均未恢复至正常水平。在接下来的18个月中，AP松弛度增加并恢复到术前水平。根据Lysholm评分，2年后32例患者中有28例被评为良好或优秀。AP松弛度与功能测试之间缺乏相关性。
