Abstract:Objective To explore the short-term results of arthroscopic Brostr?m-Gould for chronic lateral ankle instability.Methods Retrospective analysis the clinical data of 23 patients with chronic ankle instability treated with arthroscopic Brostr?m-Gould from March 2017 to January 2019, of which 14 were male and 9 were female, with an average age of 24.7 years (range: 19~48 years old). Preoperative MRI scans and stress radiographs were taken. The ankle joint was fixed in neutral position with U-cast after operation, functional boots were replaced 2 weeks later and functional exercise began, and full weight bearing with orthosis started in 6 weeks postoperatively. Functional evaluation carried out according to the hind-foot score by American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS).Results All the patients were followed up for 13 to 28 months (an average of 19.5 months). The AOFAS scores increased from (52.8 ± 14.3) (range 27~65) preoperation to (91.2 ± 6.4) at the last follow-up (range 78~100) (P < 0.01); The preoperative VAS score (6.9 ± 1.7), which was significantly higher than (1.4 ± 0.8) at the last follow-up (P < 0.01). There was no wound infection in any of the cases, and one patient developed symptoms of superficial peroneal nerve injury. After 10 weeks of oral mecobalamin capsules and physical therapy, she recovered after 3 months. No patients experienced any recurrent episodes of ankle instability.Conclusion Arthroscopic brostrom-gould for chronic lateral ankle instability is an effectice treatment in the short-term follow-up.
