Physical Therapy Timing Matters After Rotator Cuff Repair

NEW YORK (Reuters Health) – Following rotator cuff repair (RCR), it might be best to delay the start of physical therapy (PT) by at least one week, a new study hints.

“Although many studies have demonstrated decreased stiffness with beginning PT early, studies have also demonstrated that early PT increases repair failure,” researchers note in the Journal of the American Academy of Orthopaedic Surgeons.

They looked at the effect of PT and rehabilitation timing on revision surgery and capsulitis rates after RCR in 64,842 Medicare patients who underwent RCR and started PT within 13 weeks of surgery.

They found that starting PT within one week after surgery was associated with a significantly higher revision-surgery rate compared with starting PT in weeks two to five, six to nine, or 10 to 13 (6.9% vs. 3.6% among all other groups, P=0.001).

In multivariate analysis, starting PT within one week of surgery was associated with a significantly higher rate of revision surgery compared with starting PT after one week (odds ratio, 2.1; P<0.001).

No association was found between timing of beginning PT and capsulitis rates in multivariate analysis.

This study, which is the largest to date on the topic of rehabilitation timing for RCR, “calls into question the use of an early passive range of motion protocol for older patient cohort,” write Quinn Stillson and colleagues at the University of Chicago.

They say further studies are needed to “conclusively determine the most efficacious time to begin rehabilitation post-RCR.”
