Young women with obesity have a higher areal bone mineral density, better hip structure and higher volumetric BMD in all femoral compartments compared with women with normal weight, according to a study published in Bone.

Use of the Exeter Universal cemented stem during total hip arthroplasty in young patients had “excellent survivorship” at 20 years, according to published results.

Multiplex polymerase chain reaction, which uses polymerase chain reaction to simultaneously amplify several different next-generation DNA sequences, had 25.6% sensitivity when performed using Musculoskeletal Infection Society criteria for aspirate or tissue samples collected during 93 revision primary total joint arthroplasties and 77 primary total joint arthroplasties, according to study results.

Among patients with hip or knee osteoarthritis, treatment with 5-mg doses of tanezumab statistically significantly improved pain, physical function and Patient’s Global Assessment of OA scores, while 2.5-mg doses achieved just two endpoints, according to data published in the Annals of the Rheumatic Diseases.

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.
