A new technique is described for arthroscopic reduction and internal fixation (ARIF) of avulsion fractures involving the insertion of the anterior cruciate ligament (ACL). Conventional methods of treatment of ACL avulsion in adults may lead to suboptimal results owing to stiffness from either prolonged immobilization or the morbidity of arthrotomy. Contemporary techniques of arthroscopic reduction and percutaneous pinning do not achieve rigid fixation and thus still require cast immobilization. The placement of cannulated screws through the anteromedial arthroscopic portal provides rigid fixation while avoiding arthrotomy, allowing early mobilization and return to activity. The possibility of interstitial damage to the ACL and implications regarding tensioning of the ligament are considered A typical case illustrates ARIF of ACL avulsion. The technique minimizes morbidity and optimizes function.
本文描述了一种用于关节镜下复位和内固定（ARIF）涉及前交叉韧带（ACL）附着点撕脱骨折的新技术。由于长时间固定导致的僵硬或关节切开术的并发症，成人ACL撕脱的传统治疗方法可能导致效果不理想。当代关节镜下复位和经皮穿针技术无法实现牢固固定，因此仍需要石膏固定。通过关节镜前内侧入路置入空心螺钉可提供牢固固定，同时避免关节切开术，允许早期活动并恢复运动。考虑到对ACL的间隙损伤可能性以及韧带张紧的影响。一个典型病例说明了ACL撕脱的ARIF。该技术可将并发症降至最低并优化功能。
