Total Joint Replacement

Results of a matched cohort comparison of 45 patients with medial meniscal root tears who underwent either nonsurgical management, partial meniscectomy or repair showed significant differences among the groups for progression to knee arthroplasty, with the meniscus root repair group having significantly less arthritic progression based on changes in Kellgren-Lawrence grade.

Use of a medially stabilized implant system in patients undergoing total knee arthroplasty yielded superior clinical outcomes compared with a posterior-stabilized implant system, according to results.

Published results showed variation in total inpatient cost between different subspecialties of arthroplasty, with implant cost found to be the main driver of cost variation.

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.

Among 40 patients who underwent total knee arthroplasty for osteoarthritis, results of a prospective cohort study showed next-generation sequencing identified at least one positive organism that was native to the patient’s knee in 12 patients. Furthermore, 4.6 organisms were identified, on average, in patients with positive next-generation sequencing results.

Surgeon charges and payments are not increasing at the same rate as hospital charges and payments for total hip arthroplasty, even with stable patient comorbidity rates and a decreasing length of stay, 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.

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.

Use of a quality improvement initiative effectively decreased blood transfusions and kept transfusions within the American Association of Blood Banks guidelines in patients undergoing hip and knee arthroplasty, according to results.
