Does physical therapy work to fix hip labral tears? How effective is surgery for hip labral tears? This hip labrum tear research study claims that arthroscopic surgery is more effective for hip labrum tears than physical therapy, but the study is plagued with problems. It had a very high crossover rate, a terrible physical therapy protocol for hip pain, and massive problems with bias in how the study was constructed. Even so, the study still showed that surgery for hip labrum tears is largely ineffective.
