Comparison of MBR + Suture Tape, MBR, and Anatomic Reconstruction for CLAI in GJL Cases: A Prospective Cohort Study

Peking University Third Hospital114 enrolled

Overview

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.

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.

Medical Language ↔ Plain English

Inclusion Criteria: * Clinical diagnosis of lateral ankle pain and instability Beighton score ≥4 Age with 18 to 60 years Exclusion Criteria: * 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

Outcomes

Primary Outcomes

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.

Time frame: postoperative Karlsson score at 1 year

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.

Time frame: postoperative Karlsson score at 2 years

Secondary Outcomes

Anterior displacement and talar tilt angle in stress radiography

The outcomes are common indicators for evaluation the lateral stability of ankle

Time frame: postoperative radiographic measures at 2 years
