Modified Broström Repair With and Without Augmentation Using Suture Tape for Chronic Lateral Ankle Instability

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Ankle Instability Research

Background:

• Chronic lateral ankle instability often requires surgical intervention.
• The modified Broström repair is a common surgical technique.
• Augmentation techniques aim to improve repair durability and patient outcomes.

Purpose of the Study:

• To compare clinical and radiological outcomes of modified Broström repair with suture tape augmentation (MBA) versus standard modified Broström repair (MB).
• To evaluate the effectiveness of MBA in treating chronic lateral ankle instability.

Main Methods:

• Retrospective study of 53 patients with chronic lateral ankle instability.
• Comparison between 25 patients treated with MBA and 28 patients treated with MB.
• Evaluation using AOFAS, FAAM, ROM, VAS, talar tilt angle (TTA), and anterior talar translation (ATT) at 2-year follow-up.

Main Results:

• Both MBA and MB groups showed significant improvements post-surgery.
• The MBA group demonstrated superior outcomes in FAAM Sport and total scores at final follow-up (P < 0.05).
• No significant differences were observed in other clinical or radiological outcomes between the groups.

Conclusions:

• Modified Broström repair with suture tape augmentation (MBA) shows promising results for chronic lateral ankle instability.
• MBA may offer advantages in functional scores compared to standard MB.
• Further investigation is warranted to validate these findings and explore long-term efficacy.
