Arthroscopic resection of recurrent wrist ganglions - A retrospective study of 17 patients.

BACKGROUND: Arthroscopic resection has become a favorable alternative for wrist ganglions. However, for recurrent wrist ganglions, arthroscopic resection is relatively contraindicated. The purpose of this study was to evaluate the clinical outcomes of arthroscopic resection for recurrent wrist ganglions and to identify their safety and efficacy. METHODS: From June 2011 to February 2017, 17 patients with recurrent wrist ganglion were treated with arthroscopic resection. We evaluated the visual analog scale, modified Mayo wrist score, and Disabilities of Arm, Shoulder and Hand Outcome Measure preoperatively and at the final follow-up. Patients were questioned for pain reduction, pain during pushups, and any difficulty in returning to work. Recurrence and complications were also assessed at each follow-up visit. RESULTS: We enrolled 17 patients and median follow-up was 58 months. The reduction in pain was significant. Only 2 of the 17 patients had residual pain after arthroscopic resection. One female patient showed recurrences 3 years later. Although 2 cases of stiffness were noted after the operation, no significant complication was present 3 months postoperatively. Most patients had good recovery and could resume work; however, 2 patients reported fair recovery. CONCLUSION: The results of this study confirmed that arthroscopic excision could be an effective and safe treatment for recurrent ganglions; therefore, should not be contraindicated for treating recurrent wrist ganglions. Nevertheless, further prospective studies with larger patient numbers are needed to establish a stronger evidence for arthroscopic resection of recurrent wrist ganglions.
