From 1973 to 1987, 28 patients seen at our institution sustained isolated posterior cruciate ligament tears. Of these 28 patients, 25 were reevaluated at an average followup of 7 years and 1 month after secondary reconstruction of the posterior cruciate ligament using the semitendinosus and gracilis tendons alone or with an extraarticular procedure. Subjectively, 22 of 25 patients related no restrictions regarding activities of daily living, with 14 of 25 patients being able to return to their previous competitive level in sports. Objective evaluation after reconstruction revealed no change in the preoperative and postoperative posterior drawer examination in 13 of 25 patients, a finding confirmed by KT-1000 arthrometer measurements. Radiographic evaluation revealed degenerative changes predominantly involving the medial and patellofemoral compartments in 15 of 25 patients. Despite optimistic subjective reporting, this long-term retrospective study reveals that this procedure inconsistently limits posterior instability and therefore cannot be recommended.
1973年至1987年期间，我院收治了28例单纯后交叉韧带撕裂患者。在这28例患者中，25例在单独使用半腱肌和股薄肌腱或联合关节外手术对后交叉韧带进行二期重建后，平均随访7年零1个月时接受了再次评估。主观上，25例患者中有22例表示日常生活活动没有受限，25例患者中有14例能够恢复到之前的运动竞技水平。重建后的客观评估显示，25例患者中有13例术前和术后的后抽屉试验结果无变化，这一结果经KT - 1000关节测压仪测量得到证实。影像学评估显示，25例患者中有15例出现了主要累及内侧和髌股关节间隙的退行性改变。尽管主观报告较为乐观，但这项长期回顾性研究表明，该手术对限制后向不稳的效果并不一致，因此不推荐使用。
