For patients with osteonecrosis, primary total hip arthroplasty with highly cross-linked polyethylene liner has shown excellent implant survivorship and functional effects, according to study results.

For patients with advanced hip osteoarthritis, intra-articular hip corticosteroid injections will not provide a long-term solution for pain or prolong the time to total hip arthroplasty, according to study results.

Published results showed MRI may be an accurate tool in measuring hip labral width in patients with femoroacetabular impingement, with strong agreement between radiologic and arthroscopic measurements, as well as no significant differences between MRI modalities.

In a retrospective review, researchers found use of bipolar and press-fit implants in hemiarthroplasty for treatment of hip fractures increased construct costs and had little evidence of improved outcomes compared with the use of cemented monopolar implants.

The alpha-defensin lateral-flow test showed a high sensitivity and specificity in detecting periprosthetic joint infection prior to revision total joint arthroplasty, according to recent study results.

The American Association of Hip and Knee Surgeons announced C. Lowry Barnes, MD, as president during its board of directors meeting, which was held on video conference due to the cancellation of the American Academy of Orthopaedic Surgeons Annual Meeting.

A popular bearing surface from the 1990s to the mid-2000s, published literature estimated more than 1 million metal-on-metal total hip arthroplasties were performed since the design’s introduction, with 80% remaining in situ. However, metal-on-metal hip implant use decreased 10 years after its peak due to revisions related to adverse reaction to metal debris, infection and aseptic loosening.

For high-level athletes with bilateral femoroacetabular impingement and labral tears, staged bilateral hip arthroscopy performed 4 to six weeks apart is a safe and effective treatment option, according to a study by researchers in the department of orthopedics at Mayo Clinic Arizona.
