Improved hip kinematics and bone preservation have been reported after resurfacing total hip replacement (THRS). On the other hand, hip kinematics with standard total hip replacement (THR) is optimized with large diameter femoral heads (BFH-THR). The purpose of this study is to evaluate the functional outcomes of THRS and BFH-THR and correlate these results to bone preservation or the large femoral heads. Thirty-one patients were included in the study. Gait speed, postural balance, proprioception and overall performance. Our results demonstrated a non-statistically significant improvement in gait, postural balance and proprioception in the THRS confronting to BFH-THR group. THRS provide identical outcomes to traditional BFH-THR. The THRS choice as bone preserving procedure in younger patients is still to be evaluated.

Patient Reported

Patient-reported outcome and satisfaction scores have become increasingly important in evaluating successful surgery. This case-matched control study compared patient-reported outcome and satisfaction data following hip resurfacing and total hip arthroplasty. Thirty-three consecutive patients selected for hip resurfacing were compared with 99 patients undergoing cemented total hip replacement (THR), matched for age, sex and pathology. Participants completed a Short-Form 12 Health Survey (SF-12) and Oxford Hip Score questionnaire preoperatively and 6 months post operatively with an additional patient satisfaction questionnaire. There was no difference in length of hospital stay. While both groups reported improved outcome scores, multivariate regression analysis did not demonstrate any significant benefit for one group over the other. Both groups reported high levels of satisfaction, which tended to be better in patients undergoing hip resurfacing.

Joint Prostheses

The UHMWPE acetabular cups are the most popular joints for joint prostheses after Charnley introduced UHMWPE for the acetabular component in 1962. It has been demonstrated that polyethylene wear remains the main source of particles in the THR and therefore requires particular attention. The paper presents a series of theoretical and practical aspects regarding the wear of acetabular cups (made of UHMWPE) from the total hip prosthesis component. At the same time, the other tribological phenomena that occur in these MoP (metal on polyethylene) combinations are treated, such as lubrication and friction. Total Hip Replacement & Hip Resurfacing A hip replacement involves replacing the hip joint with a mechanical bearing system which is comprised of a femoral component and an acetabular component. During a hip replacement the acetabulum is reamed and the acetabular component is fitted into the cavity and the femoral component can either be placed over a reamed femoral head, in a procedure referred to as hip resurfacing, or positioned inside the femoral shaft during a total hip replacement [1].
