Risk factors of thigh pain following total hip arthroplasty with short, tapered-wedge stem.

Risk factors of pain following THA with short, tapered-wedge stem were high activity level, Dorr type C femoral bone shape, and stem tip contacting the distal bone surface. Moreover, post-operative cortical hypertrophy at the distal stem tip significantly increased the incidence of thigh pain. Therefore, we must pay attention to the aforementioned factors to avoid post-operative thigh pain when using a short, tapered-wedge stem.
