Study: Amount of Limb Lengthening in THA Is Associated with Postoperative Hip Flexion ROM
A larger amount of limb lengthening during total hip arthroplasty (THA) was associated with decreased hip flexion range of motion (ROM) at one year follow-up, according to a retrospective study published in the March 15 issue of the Journal of the AAOS ®. In total, 120 patients who underwent unilateral THA were assessed. Male sex was also associated with smaller postoperative hip flexion ROM. Cup inclination and anteversion were not significantly associated with decreased one-year hip flexion ROM.
A study published online in the Journal of Shoulder and Elbow Surgery reported durable outcomes of all-arthroscopic rotator cuff repair at a minimum follow-up of 15 years. Preoperative functional scores were collected from 193 patients, 60 of whom were available for mean follow-up of 16.5 years. At long-term follow-up, there were significant improvements in American Shoulder and Elbow Surgeons and pain scores compared to baseline levels. Seven patients (11.67 percent) required revision. Older age and female sex were associated with patient-reported outcome scores.
Systematic Review Compares Accuracy of Clinical Tests for ACL Tear
A systematic review published online in Knee Surgery, Sports Traumatology, Arthroscopy found that the Lever sign test and the pivot shift test demonstrated the highest diagnostic accuracy for ACL tears compared with the Lachman Test and the anterior drawer test. Pooled estimates from studies reporting specificity and/or sensitivity, respectively, reported the following levels: anterior drawer, 83 percent and 85 percent; Lachman test, 81 percent and 85 percent; pivot shift, 55 percent and 94 percent; Lever sign, 83 percent and 91 percent.
Study: Improving Adherence to Exercise Regimen in Patients with Lower Limb OA
A systematic review published online in BMC Musculoskeletal Disorders found that booster sessions and telephone communications may improve adherence to physiotherapy exercise regimens in patients with lower limb osteoarthritis (OA). Five studies were included. Booster sessions and telephone communications were associated with 89.7 percent and 86 percent adherence, respectively, at more than 12 months. Increasing exercise adherence was associated with improvements in pain, stiffness, and function.
The selection process for members to serve on the AAOS Board of Directors (BoD) can seem mysterious. As the new members for 2022 prepare to start their terms of service in March, after the membership formally votes on the slate of nominees at the Business Meeting at the AAOS 2022 Annual Meeting, Kristy L. Weber, MD, FAAOS, an AAOS past president, describes the criteria for selecting the people who will ascend through the AAOS leadership line.
Upcoming Free Webinar: Creating a Global Orthopaedic Culture in which Everyone Can Thrive
Tune in on March 19 from 8 to 9:30 am CT for a presentation by members of the International Orthopaedic Diversity Alliance to raise awareness of the need for diversity, equity, and inclusion (DEI) in orthopaedic surgery around the world. The objective is to increase awareness of the challenges faced by underrepresented groups in orthopaedic surgery, challenge the audience to improve DEI by serving as allies, and learn about opportunities and next steps to create culture change in orthopaedic surgery. This webinar is free for all individuals in the field of orthopaedics. Non-AAOS members will need to create a non-member account to complete their registration.
