"About 80 to 90% of the rotator cuff repairs I perform now are arthroscopic," says Mark Schwartz, MD, a Virtua Health orthopedic surgeon. He notes that with arthroscopy: "There is much better cosmesis and patients report significantly less pain in the first six to eight weeks post-op because there has been less trauma to the associated areas, especially the deltoid muscle." Unlike open surgery, adds Dr. Schwartz: "With arthroscopic repair, we can begin rehabilitating patients within the first week."
