Review of Variability in Rehabilitation Protocols after Lateral Ankle Ligament Surgery

CATEGORY: Ankle; Sports INTRODUCTION/PURPOSE: Ankle sprains are one of the most common athletic injuries. If a patient fails to improve through conservative management, surgery is an option to restore ankle stability. The purpose of this study is to analyze the variability across rehabilitation for patients undergoing lateral ankle ligament repair, reconstruction, or suture tape augmentation. METHODS: 26 protocols were found. Inclusion criteria was protocols for ankle ligament surgery. Protocols for nonoperative care were excluded. A rubric was created to analyze weightbearing, range of motion (ROM), immobilization, single leg exercises, return to running, and return to sport (RTS). RESULTS: There was variability especially in recommendations for immobilizing brace, partial and full weigh bearing, specific ROM movements of the ankle, and return to single leg exercise and running. For repair and reconstruction, none of these categories had greater than 60% agreement. 100% (12/12) of repair and 86% (12/14) of reconstruction protocols recommended no ROM postoperatively, and 86% (6/7) repair and 78% (11/14) reconstruction recommended no weightbearing postoperatively, making postoperative ROM and weightbearing status the most consistent aspects across protocols. Suture tape augmentation protocols generally allowed rehabilitation on a quicker timeline with full weightbearing by week 4-6 in 100% (3/3) of protocols and full ROM by week 8-10 in 66% (2/3). RTS was consistent in repair protocols (100% at week 12-16). CONCLUSION: ROM was variable across protocols and did not always match up with supporting literature. Return to sport was likely to correlate between protocols and the literature. Weightbearing was consistent between protocols. The variability between programs demonstrated the need for standardization of rehabilitation.
