Gender Differences in Outcome After Modified Broström Procedure for Chronic Lateral Ankle Instability

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Anatomy

Background:

• Chronic lateral ankle instability is frequently treated with the modified Broström procedure.
• Previous studies have not investigated gender-based differences in outcomes following this procedure.
• This study aimed to compare the outcomes of the modified Broström procedure between men and women.

Purpose of the Study:

• To compare the clinical and radiographic outcomes of the modified Broström procedure in male and female patients.
• To determine if gender influences the effectiveness of the modified Broström procedure for chronic lateral ankle instability.

Main Methods:

• A retrospective comparative cohort study included 155 patients (155 ankles) undergoing the modified Broström procedure.
• Patients were divided into a men's group (94 ankles) and a women's group (61 ankles).
• Outcomes were assessed using the Karlsson score, American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, talar tilt, and anterior talar translation, with a mean follow-up of 42.8 months.

Main Results:

• Both men and women showed significant improvements in Karlsson and AOFAS scores post-surgery.
• Radiographic measures, including talar tilt and anterior talar translation, also demonstrated significant improvement in both groups.
• No statistically significant differences were observed between men and women in any of the evaluated clinical or radiographic outcomes.

Conclusions:

• The modified Broström procedure demonstrates comparable and favorable functional and radiographic outcomes in both male and female patients.
• Gender does not appear to be a significant factor affecting the success of the modified Broström procedure for chronic lateral ankle instability.
• The procedure is deemed effective and reliable for treating chronic lateral ankle instability across genders.
