Outcomes Following Modified Broström for Chronic Lateral Ankle Instability With and Without Peroneal Tendon...

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Ankle Instability Research

Background:

• The impact of peroneal tendon exploration during modified Broström procedures for lateral ankle instability is not well-established.
• This study investigates whether concurrent peroneal exploration affects outcomes compared to the modified Broström procedure alone.

Purpose of the Study:

• To compare the functional outcomes and military retention rates of patients undergoing modified Broström procedure with and without peroneal tendon exploration.
• To determine if peroneal exploration influences patient satisfaction after surgical treatment for lateral ankle instability.

Main Methods:

• Retrospective analysis of patients who underwent modified Broström procedure, with a comparison between those who also had peroneal exploration and those who did not.
• Evaluation of Foot and Ankle Outcome Scores (FAOS) and military retention data, including return to duty and medical discharge rates.

Main Results:

• No significant differences were observed in overall FAOS or any subcategory between the two groups (P = .541).
• Military retention rates (47% vs. 33%, P = .518) and medical discharge rates (1 vs. 6, P = .109) showed no significant difference.
• Patient satisfaction was comparable, with 71% in the modified Broström only group and 79% in the peroneal exploration group reporting satisfaction (P = .529).

Conclusions:

• Peroneal tendon exploration at the time of modified Broström surgery for lateral ankle instability does not yield significantly different outcomes compared to the modified Broström procedure alone.
• The addition of peroneal exploration did not impact functional scores, return to duty, medical discharge, or patient satisfaction.
