title: Lengthening of anterior cruciate ligament graft. Roentgen stereophotogrammetry of 32 cases 2 years after repair.
abstract: 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.
