Publicly Accessible Rehabilitation Protocols for Acromioclavicular Joint Reconstruction Are Widely Variable

PURPOSE: The purpose of this study was to assess the availability and variability of publicly accessible acromioclavicular (AC) joint reconstruction rehabilitation protocols. METHODS: Protocols were identified by searching the websites of orthopedic surgery residency programs in the United States located from the Fellowship and Residency Electronic Interactive Database Access System. Private practice groups with publicly available protocols were also included. RESULTS: Twenty-one protocols were included for review. Four of 14 (29%) protocols suggested starting passive range of motion (ROM) at postoperative week 2. Six of 20 (30%) protocols recommended initiation of full ROM at 6 weeks. Active ROM beginning at 6 weeks was recommended by 6 of 20 (30%) protocols. Six of 16 (38%) protocols recommended initiating active assisted ROM at 6 weeks. Sling immobilization for 6 weeks was recommended by 8 of 18 (44%) protocols. Shoulder isometric exercise initiated at 4 weeks was recommended by 4 of 13 (31%) protocols. Seven of 21 (33%) protocols recommended initiating shoulder strengthening at 12 weeks postoperatively. Return to sport time was included in 17 (81%) protocols with a range of 12 to 48 weeks (mean, 22 weeks). CONCLUSIONS: There was substantial variability in publicly accessible AC joint rehabilitation protocols, including a wide range in the recommendations for appropriate time to return to sport. Although strengthening exercises, active ROM, and active assisted ROM were recommended by most protocols, there were considerable differences in recommendations for when to initiate these rehabilitation components. CLINICAL RELEVANCE: Rehabilitation is important for outcomes of AC joint reconstruction. This study shows the variability present in rehabilitation recommendations among online-accessible AC joint reconstruction rehabilitation protocols.
