Hip Manipulation Under Anesthesia for Post-Hip Arthroscopy Pericapsular Scarring: Indications and Techniques.

Hip arthroscopy has become an increasingly common procedure with expanding indications over the last several decades. With the increase in number of procedures performed a complication profile has emerged, although there is yet to be a formal classification system for complications. The most cited complications include lateral femoral cutaneous nerve neuropraxia, other sensory deficits, chondral or labral iatrogenic damage, superficial infection and deep vein thrombosis. One complication that has not yet been well documented in the literature is pericapsular scarring/adhesions resulting in decreased hip range of motion and function. If this complication is noted to persist after adequate impingement resection and a rigorous post-operative physical therapy regimen, the senior author has addressed this with a hip manipulation under anesthesia. Therefore, this techniques paper aims to describe pericapsular scarring as a post hip-arthroscopy condition which may cause pain and demonstrate our technique to address this diagnosis through hip manipulation under anesthesia.
