The aim is to evaluate the effectiveness of pericardium patch as a tendon augmentation graft in the repair of massive rotator cuff tear. This is prospective study analysis of a consecutive series of 60 patients who underwent open repair of a massive rotator cuff tear with patch between 1999 and 2007. The inclusion criteria were: symptomatic with pain, deficit of elevation, not responsive to the physiotherapy, tear size (massive: 2 or more tendons), minimum follow-up of 2 years since surgery, active and motivated patients. All were assessed preoperatively with plain radiographs (anteroposterior and axillary views), ultrasound and NMR of the shoulder. The study group consistent of 60 patients (39 men and 21 women) with the mean age of was 66 years (range, 46–81). The mean duration of symptoms before repair was 18 months (range 3–48). Patients were assessed with UCLA score, visual analog scale (Vas scale) and ultrasound preoperatively, at 1 year, and at 3 years. The change in UCLA scores, Vas scale were analyzed with the paired Student's test, assuming a normal distribution of the total score. Satisfactory results were achieved in 49 patients: mean preoperative UCLA score improved from 9.3 to 16.9 at final follow-up.

For pain, the mean preoperative value of Vas scale was 9,1, postoperative mean value was 4.9. Range of motion and abduction power improved not significantly after surgery, although patients satisfaction levels were high. Imaging studies identified intact patch in 15 patients and patch detachment in 45. No adverse side effects (infection, rejection, allergy) were reported during the study period.

The results of our study suggest that patients (appropriately selected) with a massive full-thickness rotator cuff tear can be expected to have a pain relief after repair, but not a significantly improved of functional outcome.
