Observational model: COHORT
Time perspective: PROSPECTIVE
Sampling method: PROBABILITY_SAMPLE
Study population: The patients who go to visit a doctor for persistent lateral ankle pain and instability over three months and invalid conservative treatment, with the age of 18- 60 years. If the Beighton score of the patient is ≥4 and the exclusion criteria are met, he or she is going to be advised to participate in this study.

Brief summary: GJL is a risk factor for postoperative recurrent instability following an MBR for CLAI. BPR with suture tape augmentation and anatomic reconstruction may provide more strength and stability. However, BPR with suture tape augmentation may lead to rejection of the suture tape, while anatomic reconstruction may be associated with more trauma. In addition, the outcomes between the BPR with suture tape augmentation and anatomic reconstruction were unknown.

Detailed description: Generalized joint laxity (GJL) is a risk factor for postoperative recurrent instability following an open modified Broström repair (MBR) for chronic lateral ankle instability (CLAI). MBR with suture tape augmentation and anatomic reconstruction may provide more strength and stability. However, BPR with suture tape augmentation may lead to rejection of the suture tape, while anatomic reconstruction may be associated with more trauma. In addition, the outcomes between the BPR with suture tape augmentation and anatomic reconstruction were unknown.

Eligibility criteria: Inclusion Criteria:
