Patient compliance with post-surgical sling use was recently examined in a study published in the Journal of Shoulder and Elbow Surgery.
Fifty patients who had undergone rotator cuff repair were followed and surveyed. An abduction sling was prescribed for six weeks following the procedure. Eighty-eight percent of participants reported wearing it as directed.
Why the Study’s Conclusions Should Be Read Carefully
No major differences in clinical outcome were identified between compliant and non-compliant patients. However, two significant limitations are worth noting before drawing broad conclusions.
First, the sample size was too small to be statistically meaningful. Only 12% of patients — roughly six individuals — did not follow sling instructions. That group is far too small for a fair comparison.
Second, compliance was self-reported by patients. Prior research has shown that patients tend to overestimate how consistently they follow post-operative instructions. In the future, sensor technology — such as a temperature sensor built into the sling — could offer a far more accurate picture of actual wear time.
What This Means for Surgeons
A more rigorous study design is needed before firm conclusions can be drawn. Randomly assigning post-operative patients to a no-sling group is not considered ethical, as clinical equipoise does not exist for this question.
Larger patient populations and objective compliance monitoring would be needed for meaningful results.

The Bottom Line for Patients
The short answer: a sling is still required after rotator cuff repair surgery.
That said, not all shoulder procedures carry the same recovery requirements. A distinction is made between repair and debridement. A repair reconnects torn tissue to bone and demands a period of immobilization to allow proper healing. A debridement — or “clean-out” — simply smooths damaged tissue edges. Procedures such as acromioplasty, distal clavicle excision, and bicep tenotomy generally do not require the same extended sling use as a full rotator cuff repair.
Every recovery plan is individualized based on the procedure performed and the patient’s specific anatomy and activity goals.
