The arthroscopic management of frozen ankle.

PURPOSE: The purpose of this study was to evaluate a combined anterior and posterior arthroscopic approach in the treatment of frozen ankle. TYPE OF STUDY: Retrospective case series. METHODS: Five patients with post-traumatic frozen ankle were evaluated. RESULTS: After an average follow-up of 32.6 months (range, 24 to 42 months), the average American Orthopaedic Foot and Ankle Society hindfoot-ankle score was improved from 63.8 point (range, 55-74) to 88.6 point (range, 81-100). The average ankle dorsiflexion improved from 1 degrees (range, 0 degrees to 5 degrees) to 19 degrees (range, 15 degrees to 25 degrees). The average ankle plantarflexion improved from 16 degrees (range 10 degrees to 20 degrees) to 39 degrees (range, 30 degrees to 45 degrees). CONCLUSIONS: Combined posterior ankle endoscopy and anterior ankle arthroscopy is effective in the treatment of post-traumatic frozen ankle. LEVEL OF EVIDENCE: Level 4.

Tendoscopic debridement for stage I posterior tibial tendon dysfunction.

Our objective is to assess whether the tendoscopic synovectomy is effective to control the stage I posterior tibial tendon dysfunction. Our study is a retrospective one. The participants, six patients with stage I posterior tibial tendon dysfunction, were treated with tendoscopy with synovectomy for the past 3 years. The results show that this is a safe procedure and we could achieve similar effectiveness as the traditional open procedure. There was no complication found. None of our patients have progressed to stage II or above posterior tibial tendon dysfunction. In conclusion, tendoscopic debridement is a minimal invasive surgery. It is effective to control the stage I posterior tibial tendon dysfunction. In addition, it had the advantages of smaller scars, less wound pain and a short hospital stay.

Arthroscopic Lapidus arthrodesis.

Lapidus arthrodesis is the surgical treatment of choice for symptomatic hypermobility of the medial cuneiform metatarsal joint that is not responding to conservative treatment. The open procedure was criticized for its prolonged healing, high nonunion rate, and the tendency for dorsal angulation of the first metatarsal. We describe an arthroscopic approach that has the advantage of more thorough preparation of the fusion site with minimal bone removal and better control of the arthrodesis position and with less chance of malunion.
