Abstract

We present a case of a chondral lesion after anterior cruciate ligament (ACL) reconstruction caused by femoral cross-pin breakage and intra-articular migration of the fragment. A 20-year-old man initially underwent ACL reconstruction using a hamstring autograft. The RigidFix bioabsorbable cross-pin (DePuy Mitek) was used for the femoral fixation. The patient returned to a pre-injury level of activity (professional soccer player) 6 months postoperatively. However, 20 months postoperatively, the patient presented with effusion and lateral joint-line pain after practice, without signs of instability in clinical examination. Conservative treatment failed and at re-arthroscopy a chondral lesion of the lateral femoral and tibial condyle was found, which had been caused by the broken femoral cross-pin. The fragment was removed and the symptoms resolved. Orthopaedic surgeons should be aware of this complication when using a bioabsorbable cross-pin for femoral fixation in ACL reconstruction.

摘要

我们报告一例前交叉韧带（ACL）重建术后因股骨交叉销断裂及碎片关节内移位导致的软骨损伤病例。一名20岁男性最初采用自体腘绳肌肌腱进行ACL重建。股骨固定使用RigidFix生物可吸收交叉销（DePuy Mitek公司）。患者术后6个月恢复到受伤前的活动水平（职业足球运动员）。然而，术后20个月，患者在训练后出现关节积液和外侧关节线疼痛，临床检查无不稳定迹象。保守治疗无效，再次关节镜检查时发现股骨外侧髁和胫骨髁有软骨损伤，系股骨交叉销断裂所致。取出碎片后症状缓解。骨科医生在ACL重建术中使用生物可吸收交叉销进行股骨固定时应注意这种并发症。
