In contrast to this, Deutsch et al 7 reported on 70 patients who had a single row arthroscopic rotator cuff repair with simple suture configuration randomized to one of two physical therapy protocols that were different only in that the "Standard" protocol began passive forward elevation on postoperative day 7 (N=37), whereas the "Delayed" protocol began passive forward elevation after 4 weeks (N=33). At 6 months range of motion was not different, however ultrasound examination demonstrated 19% of the repairs failed in the "Standard" group, whereas only 9% failed in the "Delayed" group (p<0.05).
