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.
Clinical diagnosis of lateral ankle pain and instability Beighton score ≥4 Age with 18 to 60 years
Patients with an acute or subacute ankle injury (within 3 months) Injury of the deltoid ligament Alignment of lower extremity greater than 5 degrees Fractures of the lower extremity Stage III or IV osteoarthritis Patients who refused to participate in the study
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.

Karlsson-Peterson score
This score is a primary scale for lateral ankle instability, with a maximum value of 100 and minimum value of 0. Larger Karlsson-Peterson score represents better ankle functional outcomes.
