采用新鲜同种异体骨软骨移植修复92例膝关节创伤后骨关节缺损。移植时，通过胫骨上段或股骨髁上截骨术矫正内翻或外翻畸形。进行了生存率分析，失败定义为需要翻修手术或术前症状持续存在，5年成功率为75%，10年为64%，14年为63%。双极移植物的失败率高于单极移植物，60岁以上患者的结果较差。结果不取决于患者的性别，膝关节内侧和外侧间室的同种异体移植物的结果相似。仔细选择患者，通过截骨术矫正关节对线不良，以及移植物的刚性固定都是成功的必要条件。我们推荐这种方法用于治疗相对年轻和活跃患者的膝关节创伤后骨软骨缺损。
Fresh osteochondral allografts were used to repair post-traumatic osteoarticular defects in 92 knees. At the time of grafting, varus or valgus deformities were corrected by upper tibial or supracondylar femoral osteotomies. A survivorship analysis was performed in which failure was defined as the need for a revision operation or the persistence of the pre-operative symptoms.There was a 75% success rate at five years, 64% at ten years and 63% at 14 years. The failure rate was higher for bipolar grafts than for unipolar and the results in patients over the age of 60 years were poor. The outcome did not depend on the sex of the patient and the results of allografts in the medial and lateral compartments of the knee were similar. Careful patient selection, correction of joint malalignment by osteotomy, and rigid fixation of the graft are all mandatory requirements for success.We recommend this method for the treatment of post-traumatic osteochondral defects in the knees of relatively young and active patients.
