Background:
Only a few studies have analyzed functional predictive factors for inferior outcomes after modified Broström procedure (MBP). The aim of the current study is to identify the influence of the preoperative dynamic reach deficit on the surgical outcomes of MBP.
Methods:
Sixty-one patients with lateral ankle instability who underwent MBP were included in the current study and followed up for a median of 24 months. The Karlsson scores and the reaches of the Star Excursion Balance Test (SEBT) were evaluated before surgery and during the last follow-up. A total of 19 prognostic factors were analyzed. The relationship between the variables and inferior outcomes (Karlsson score < 90) in the bivariate analysis was tested through the Mann-Whitney U test or the Fisher exact test. A multivariate logistic regression model was developed to investigate the influence of the selected factors on inferior outcomes.
Results:
Thirty-two of the patients had superior outcomes, and the rest had inferior outcomes. The age, gender, and body mass index of the groups with superior and inferior outcomes did not differ. Preoperative dynamic reach deficit (P = .032), osteochondral lesion of the talus (P = .004), and decreased preoperative Karlsson score (P = .004) were independent predictors of inferior outcomes.
Conclusion:
Patients with preoperative dynamic reach deficit, osteochondral lesion of the talus, or decreased preoperative Karlsson score have inferior outcomes after MBP.
Level Of Evidence:
Level III, case-control study.
