Comparison of functional results of hip resurfacing and total hip replacement: a review of the literature.

Total hip arthroplasty (THA) results in good outcomes in function and risk for revision in older patients. However, in young, active patients, it results in an increased rate of revision and poorer outcomes. Modern metal-on-metal hip resurfacing arthroplasty (HRA) is described as an appropriate treatment of hip osteoarthritis in young, active patients. The selection of an appropriate prosthesis is critical for this patient demographic. This review compares the functional results of THA and HRA and focuses on range of motion, activity level, groin pain, patient satisfaction, restoration of normal hip anatomy, and gait. Crown
