Troponin Levels Following Surgery

A study published in the HSS Journal this week found that “patients with higher postoperative cTnI levels were more likely to have cardiac complications during hip or knee replacement surgery and spinal fusions.” Researchers recommend a simple blood test to measure troponin to help identify patients who are at greater risk of a cardiac event following surgery.

Study Shows Good Outcomes for Obese TJR Patients

A study published in the Journal of Bone & Joint Surgery this week concludes that overweight patients who undergo hip or knee replacement surgery experience pain relief and functional gain similar to other patients. Researchers at the University of Massachusetts, who include several AAHKS members, “concluded that while obesity is associated with a greater risk of early complications,… Read More

VTE Prevention Review Published by HHS

The research review, “Venous Thromboembolism (VTE) Prophylaxis in Major Orthopedic Surgery: Systematic Review Update,” was published by the U.S. Department of Health & Human Services Agency for Healthcare Research and Quality last month. AAHKS made comments on the draft report. Several members served as technical experts and peer reviewers for the systematic review that provides comprehensive, scientific-based information… Read More

British Researchers Conducting Joint Infection Trial

The University of Bristol in England has started a randomized trial to investigate why some patients develop infections after their hip or knee replacement surgery, and which type of surgical revision treatment is best. According to Medical Xpress, members of the public are being asked to take part in the trial. “The NIHR-funded INFORM (Infection – Orthopaedic Management)… Read More

Participate in the AAHKS Research Consortium

The AAHKS Research Committee plans to convene a consortium of centers that have interest in conducting research related to hip and knee arthroplasty. Centers that participate in the AAHKS Research Consortium (AAHKS-RC) will be part of multi-center studies that may be funded through the Foundation for Arthroplasty Research and Education or other sources. If you would like your… Read More

Study Published on TJR Cost Effectiveness

Researchers published a study in Central Musculoskeletal Disorders concluding that “THA and TKA are cost-effective and should be recommended for the management of patients with end stage/severe knee and hip OA.” Orthopedics Today breaks down the research in four key points of the most cost-effective measures: 1) surgery without delay, 2) high-volume hospitals, 3) THA vs. non-operative strategies,… Read More
