Question In patients with rotator cuff tears, what is the relative efficacy of primary tendon repair and physiotherapy with optional secondary tendon repair for long-term outcomes?

Shoulder and Elbow Surgeons self-report score, Short-Form 36 Health Survey physical score, and strength. Patient follow-up: 98% (intention-to-treat analysis).

Main results

Methods Design: Randomized controlled trial. ClinicalTrials.gov NCT00852657.

24% of patients in the physiotherapy group had secondary tendon repair at 2 years. The main results are in the Table.

Conclusion

Allocation: Concealed.*

In patients with rotator cuff tears, primary tendon repair improved pain and some measures of function at 5 years compared with physiotherapy and optional secondary tendon repair.

Blinding: Blinded* (outcome assessors). Follow-up period: 5 years. Setting: Secondary care center in Norway. Patients: 103 patients ≥ 18 years of age (mean age 60 y, 71% men) who were referred for treatment of rotator cuff tears and had lateral shoulder pain at rest or exercise, painful motion arc, passive shoulder motion ≥ 140° for abduction and flexion, positive impingement sign, and a full-thickness tear with muscle atrophy ≤ stage 2 on magnetic resonance imaging and size ≤ 3 cm on ultrasonography. Exclusion criteria included tears > 25% of subscapularis tendon width, previous surgery on affected shoulder, or local or systemic diseases that affect shoulder function. Intervention: Primary tendon repair using an open or miniopen approach and a modified Mason-Allen technique, followed by postoperative passive range-of-motion exercises and referral for supervised physiotherapy and home exercises after discharge (n = 52); or individually tailored, outpatient physiotherapy, based on a set of 52 exercises given in 40-minute sessions twice weekly for 12 weeks and less frequently for the next 6 to 12 weeks, plus patient education and optional secondary tendon repair if the condition persisted after ≥ 15 physiotherapy sessions (n = 51). Outcomes: Primary outcome was the Constant score. Other outcomes included pain, pain-free shoulder mobility, American Primary tendon repair vs physiotherapy in patients with rotator cuff tears† Outcomes

Commentary The role of surgery in management of rotator cuff tears has become increasingly uncertain (1), and the trial by Moosmayer and colleagues adds further fuel to the debate. The study had appropriate randomization and allocation concealment, blinded outcome assessors, intention-to-treat analysis, 98% follow-up at 5 years, and adherence to the CONSORT guidelines for reporting trial results. Patients treated conservatively and those treated with either open or mini-open rotator cuff repair did not differ for final functional outcome as assessed by the Constant score. However, several issues deserve attention. First, this was a “pragmatic trial.” Although it tries to imitate real life, the lack of intervention standardization allows for confounding of treatment effect by surgical or physiotherapy techniques. Second, 24% of the physiotherapy patients were not satisfied and had surgery within the first 2 years, so the results may underestimate the true benefit of surgery. Comparing as-treated groups, patients treated surgically did slightly better at 5 years, but early vs late surgery did not differ for Constant scores. Finally, ultrasound assessment of rotator cuff integrity at 5 years showed that tear sizes increased by 5 to 24 mm in 37% of patients in the physiotherapy-only group, and these patients had worse outcomes than those with tears that remained relatively stable in size. Although Moosmayer and colleagues found no difference in Constant scores after early surgical cuff repair compared with physiotherapy, it is unclear how best to apply these results to clinical practice because of the number of crossover patients and the observed deterioration of some tears treated nonoperatively. Nonetheless, the results will allow surgeons to better educate their patients on the potential course of surgical or nonsurgical management.
