Soft-Tissue Sources of Extra-articular Pain Following Total Hip Arthroplasty: A Comprehensive Review.

Hip pain after a total hip arthroplasty is a prevalent condition. Once aseptic loosening and infection have been ruled out, the possible entities are vast. Accurate diagnosis in this patient population is challenging because they might present in different stages of their recovery process and the potential overlap of some conditions. Given the high expectations clinicians and patients have from hip arthroplasty, a multifaceted patient-specific approach is crucial to clinical decision making. Advances have been made to better stratify patients into the spectrum of management, which includes nonsurgical treatment, injections, such as orthobiologics, arthroscopic hip surgery, open surgery, and, in rare cases, revision total hip arthroplasty.
