Rehabilitation Variability After Elbow Ulnar Collateral Ligament Reconstruction.

backgroundInvestigations specifically delineating the safest and most efficacious components of physical therapy after ulnar collateral ligament (UCL) reconstruction of the elbow are lacking. As such, while a number of recommendations regarding postoperative therapy have been published, no validated rehabilitation guidelines currently exist. PURPOSE: To assess the variability of rehabilitation protocols utilized by orthopaedic residency programs in the United States (US) and those described in the scientific literature. STUDY

designCross-sectional study.

methodsOnline UCL reconstruction rehabilitation protocols from US orthopaedic programs and from the scientific literature were reviewed. A comprehensive scoring rubric was developed to assess each protocol for the presence of various rehabilitation components as well as the timing of their introduction.

resultsOverall, 22 protocols (14%) from 155 US Electronic Residency Application Service (ERAS) orthopaedic programs and 8 protocols published in the scientific literature detailing UCL reconstruction postoperative rehabilitation were identified and reviewed. After reconstruction, the majority of ERAS and review article protocols (77% and 88%, respectively) advised immediate splinting at 90° of elbow flexion. The mean time to splint discontinuation across all protocols was 2.0 weeks (range, 1-3 weeks). There was considerable variability in elbow range of motion recommendations; however, most protocols detailed goals for full extension and full flexion (>130°) at a mean 5.3 weeks (range, 4-6 weeks) and 5.5 weeks (range, 4-6 weeks), respectively. Significant diversity in the inclusion and timing of strengthening, proprioceptive, and throwing exercises was also apparent. Thirteen ERAS (59%) and 7 review article (88%) protocols specifically mentioned return to competition as an endpoint. ERAS protocols permitted return to competition significantly earlier than review article protocols (29.6 vs 39.0 weeks, respectively;

conclusionThere is notable variability in both the composition and timing of rehabilitation components across a small number of protocols available online. While our understanding of postoperative rehabilitation for UCL reconstruction evolves, outcome-based studies focused on identifying clinically beneficial modalities and metrics are necessary to enable meaningful standardization.
