Our 20‑year implant survivorship of 97.6% with the M2a‑38 bearing surpassed registry benchmarksfor THA. This large‑bearing (38 mm), full hemisphere coverage metal‑on‑metal system had no bearing wear failures,one failure of instability, one failure of fixation, and three trunnion failures, perhaps suggesting an optimum balancebetween stability of the joint and the trunnion.

The primary advantages of hip resurfacing are stability, functionality, durability, and bone preservation. Over the past 15 years, technology has changed dramatically allowing surgeons to perform hip resurfacing with minimal blood loss and good pain control.

We investigate the efficacy of a modified acetabular bone-preparation technique in reducing the incidence of two clinical problems (lack of bone ingrowth and cup shift) identified in hip resurfacing arthroplasty.

The purpose of this study was to compare the clinical outcomes of osteonecrosis (ON) and osteoarthritis (OA) patients after metal-on-metal hip resurfacing arthroplasty (HRA).

Background: The optimal surgical treatment for osteonecrosis of the femoral head has yet to be 20 elucidated. To evaluate the role of femoral fixation techniques in hip resurfacing, we present a 21 comparison of the results for two consecutive groups: Group 1 (75 hips) received hybrid hip 22 resurfacing implants with a cemented femoral component; Group 2 (103 hips) received 23 uncemented femoral components. Both groups received uncemented acetabular components. Conclusions: This study demonstrates a superior outcome for cases of osteonecrosis with 36 uncemented hip resurfacings compared to cases employing hybrid devices.
