Summary
Preoperative dynamic reach deficit, osteochondral lesions, and low Karlsson scores predict poor outcomes after modified Broström procedure (MBP) for ankle instability. Addressing these factors may improve surgical results.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Ankle biomechanics
Background:
- Limited research exists on functional predictors of poor outcomes following the modified Broström procedure (MBP).
- Identifying preoperative factors is crucial for optimizing surgical success in treating lateral ankle instability.
Purpose of the Study:
- To investigate the influence of preoperative dynamic reach deficit on surgical outcomes after MBP.
- To identify key prognostic factors associated with inferior outcomes post-MBP.
Main Methods:
- A cohort of 61 patients undergoing MBP for lateral ankle instability was analyzed.
- Preoperative and follow-up Karlsson scores and Star Excursion Balance Test (SEBT) reach were assessed.
- Bivariate and multivariate logistic regression identified predictors of inferior outcomes (Karlsson score < 90).
Main Results:
- Thirty-two patients achieved superior outcomes, while 29 had inferior outcomes.
- Preoperative dynamic reach deficit (P=.032), osteochondral talus lesions (P=.004), and lower preoperative Karlsson scores (P=.004) were significant predictors.
- Age, gender, and BMI did not differ between outcome groups.
Conclusions:
- Preoperative dynamic reach deficit, osteochondral lesions of the talus, and decreased preoperative Karlsson scores are associated with inferior outcomes after MBP.
- These findings highlight the importance of preoperative assessment of dynamic balance and joint integrity for predicting MBP success.
