Patient Reported Outcomes and Self-Assessed Function after Lateral Ankle

Given the high prevalence of lateral ankle sprains (LAS) and recurrent injuries it is critical to identify patients at elevated risk for recurrent LAS. The purpose of this study is to determine the ability of patient reported outcomes (PROs) and rehabilitation experiences to predict recurrent LAS. Participants will be separated into groups based on whether or not they received clinician supervised rehabilitation, and if they experienced a recurrent LAS within 12 months of return to pre-injury activity. PROs will be assessed in the acute stages of LAS recovery, after return to pre-injury activity, and at 6 and 12 month follow-ups. A chi-square analysis will determine differences in PROs between those who do and do not participate in clinician-supervised rehabilitation and those that do and do not sustain a recurrent LAS. A logistic regression analysis will determine the ability of PROs and rehabilitation experiences to predict recurrent LAS risk within 12 months of return to pre-injury activity. We expect that participants that perform clinician-supervised rehabilitation, and those that do not sustain a recurrent LAS will have better PRO scores. Additionally, we hypothesize that decreased PRO scores and a lack of clinician-supervised rehabilitation will be associated with increased estimated odds of recurrent LAS.
