Summary

This study evaluated cementless hip resurfacing, finding no revisions or loosening in short-term follow-up. Elevated chromium and cobalt levels were observed, suggesting further investigation for future hip resurfacing device generations.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Medical Device Engineering

Background:

  • Current hip arthroplasty standards utilize metal-on-metal bearings with cemented femoral components and cementless acetabular fixation.
  • Concerns regarding the long-term survivorship of cemented stems in conventional hip arthroplasty necessitate exploring cementless fixation for the femoral side in surface replacement arthroplasty (RSA).

Purpose of the Study:

  • To evaluate clinical and radiological data from published cementless RSA series.
  • To assess preliminary clinical outcomes, complication rates, survivorship, and metallic ion levels in Conserve Plus cementless devices.

Main Methods:

  • A literature search was conducted using PubMed with keywords related to cementless hip resurfacing.
  • Clinical outcomes, complication rates, survivorship, and metallic ion levels were measured in 94 cementless Conserve Plus devices in 90 patients.

  • Mean follow-up was 13.1 months.

    • Main Results:

    • No revisions were performed during the observed follow-up period.
    • No radiological signs of loosening or significant femoral neck narrowing were detected.
    • Whole blood chromium and cobalt levels increased, with chromium rising from 0.53 μg/l to 1.7 μg/l and cobalt from 0.54 μg/l to 1.98 μg/l.

    Conclusions:

    • Cementless "fit and fill" femoral-side fixation shows promise for future hip resurfacing device generations.
    • The design and fixation method appear to be critical factors for improved outcomes in cementless hip resurfacing.
