Effect of Physical Therapy and Rehabilitation Timing on Rotator Cuff Repair Revisions and Capsulitis

Abstract

Introduction: One variable that could potentially affect failure of a rotator cuff repair (RCR) is the timing of beginning physical therapy (PT) after the procedure. Although many studies have demonstrated decreased stiffness with beginning PT early, studies have also demonstrated that early PT increases repair failure. The goal of this study was to identify revision surgery and capsulitis rates after RCRs from an available database and determine whether an association was present with the timing of PT post-RCR. Methods: Medicare patients within the PearlDiver database who underwent RCR were stratified based on the timing of their first PT session postoperatively, and revision surgery and capsulitis rates were determined among the groups for both open and arthroscopic RCR. Demographics and comorbidities of the cohort were also used to formulate a multivariate analysis for revision surgery rate. Results: The cohort consisted of 64,842 patients who underwent RCR and started PT within 13 weeks of surgery. Starting PT within 1 week postoperatively resulted in a significantly higher revision surgery rate compared with starting PT in weeks 2 to 5, 6 to 9, or 10 to 13 (6.9% vs. 3.6% among all other groups, P = ,0.001). The multivariate analysis for revision surgery further demonstrated that starting PT within 1 week postoperatively was associated with a significantly higher rate of revision surgery compared with beginning PT after 1 week (OR = 2.086, P , 0.001). No association was found between timing of beginning PT and capsulitis rates. Conclusion: In the Medicare patient cohort, beginning PT within 1 week postoperatively was associated with a significantly higher revision surgery rate; however, no associated benefit was noted in capsulitis rates for beginning PT early. This calls into question the use of an early passive range of motion protocol for older patient cohort; however, further studies should be completed to conclusively determine the most efficacious time to begin rehabilitation post-RCR.
