Comparing Hip Resurfacing Arthroplasty (Hra) And Total Hip Arthroplasty (Tha)

The comparison of hip resurfacing arthroplasty (HRA) with total hip arthroplasty (THA) seems straightforward since both procedures are performed to treat diseases of the hip joint. However, besides biomechanical distinctions, differences in indications, treatment timing, surgical experience and technique have been demonstrated. This chapter compares the outcomes of HRA and THA from a clinical, radiographic and survivorship point of view focusing especially on the group of young and/or active patients for whom HRA was primarily developed. Objective, multi-factorial weighing of the current knowledge leads to the conclusion that hip resurfacing is the better reconstructive option for specific patient groups such as young and active males with osteoarthritis. Other patient groups such as females or patients with anatomic deformities should be assessed thoroughly and considered as HRA candidates with certain reservations.
