The dislocation rate in total hip replacement is sometimes as high as 5 percent for primary procedures and 10 percent for revisions. Impingement in total hip arthroplasty (THA), along with subluxation, is also an appreciable problem with large societal and financial costs. “Although instability now stands as the single most common reason for revision surgery, the biomechanical factors responsible for impingement, subluxation, and dislocation remain underinvestigated relative to their burden of morbidity,” said Thomas D. Brown, PhD, of the University of Iowa.
