Accurate positioning of the total ankle arthroplasty implant components with the absence of any hindfoot deformity does not preclude the development of bony impingement. In cases of ankle stiffness after total ankle arthroplasty, the usual limitation is in dorsiflexion. If triceps surae contracture is excluded or persistent restriction remains in ankle dorsiflexion after gastrocnemius recession or tendo-Achilles lengthening, posterior ankle capsulectomy, debridement of posterior ankle gutter, and release of the deep posterior deltoid ligament and the posterior talofibular ligament are indicated. In this Technical Note, the technical details of endoscopic posterior ankle decompression and release after total ankle arthroplasty are described.
在没有任何后足畸形的情况下，全踝关节置换植入部件的精确放置并不能排除骨撞击的发生。在全踝关节置换术后踝关节僵硬的病例中，通常的限制在于背屈。如果排除了小腿三头肌挛缩，或者在腓肠肌松解或跟腱延长后踝关节背屈仍持续受限，则需要进行后踝关节囊切除术、后踝关节沟清创术，以及松解深层三角韧带后束和距腓后韧带。在本技术说明中，描述了全踝关节置换术后内镜下后踝关节减压与松解的技术细节。
