COVID-19 Updates

A Message from the AAOS President

In his most recent presidential message, AAOS President Joseph A. Bosco III, MD, FAAOS, provided the latest regulatory and advocacy updates on the COVID-19 pandemic, including the Department of Health and Human Services’ plan on the initial $30 billion that will be distributed per the Coronavirus Aid, Relief, and Economic Security (CARES) Act. AAOS will provide additional details on that as it unfolds later this week. Dr. Bosco also notes that although the curve may be flattening in some areas, this pandemic and its repercussions on the orthopaedic profession are far from over: “We should all be proud of the service that we all are providing our communities in the COVID-19 fight. Rest assured that as we devote our efforts to battle COVID-19 locally, our Academy is fighting equally as hard on a state and national level to assure that we get the relief we deserve.”

Study: How Do Medicare’s PROM Collection Windows for Joint Arthroplasty Play Out in Practice?

A retrospective study published in the April issue of The Journal of Arthroplasty evaluated the Comprehensive Care for Joint Replacement’s (CJR) mandated collection window for patient-reported outcome measures (PROMs) for total hip arthroplasty (THA) and total knee arthroplasty (TKA) procedures. Primary THAs and TKAs (n = 860) performed in patients who completed the Patient-reported Outcomes Measurement Information System-10 global health survey during pre- or postoperative time periods were assessed. The main outcome measure was completion rates per the CJR collection periods (90 to zero days preoperatively and 270 to 365 days postoperatively) compared to an extended postoperative collection period of 270 to 396 days. Of the total cohort, 725 (84.3 percent) had complete preoperative surveys within 90 to zero days preoperatively. Of these patients, 215 (297 percent) completed postoperative surveys within the CJR window; extending the postoperative period from 270 to 396 days increased completion by 120 additional surveys (16.5 percent). There were no identified patient or procedural factors that were largely correlated with a higher likelihood of postoperative PROM completion.

Study Assesses Value of Countermovement Jump Tests to Diagnose Elbow Injuries in Professional Baseball Pitchers

A study published online in The American Journal of Sports Medicine analyzed the use of countermovement jump (CMJ) tests as a diagnostic tool for professional baseball pitcher conditioning. The study included more than 500 pitchers in a single professional baseball organization who performed preseason CMJ assessments before the 2013 to 2018 seasons to extract the eccentric rate of force development (ERFD), average vertical concentric force (AVCF), and concentric vertical impulse (CVI). Detailed elbow and shoulder injury rates and workout data were collected throughout the season. When taking into account pitcher age, weight, and workload, ERFD, CVI, and AVCF all significantly predicted elbow injury risk. Per the results of a CMJ scan, the three specific indicators of increased injury risk were low ERFD, combined low AVCF and high CVI, and combined high AVCF and low CVI. Shoulder injury risk appeared independent of all three CMJ test measurements.

Study Analyzes Use of Robot-assisted Pedicle Screw Placement with Tracer Fixation Device

A randomized trial published online in BMC Musculoskeletal Disorders assessed the minimal invasiveness, safety, and accuracy of robot-assisted pedicle screw placement with a modified tracer fixation device. Patients were randomized to undergo either conventional fixation (n = 25) or modified fixation (n = 27). Baseline characteristics did not largely differ between the groups. Screw placement accuracy was similar between the groups. The modified group had a significantly shorter length of unnecessary incision compared to the conventional group (6.08 mm versus 40.28 mm), as well as significantly less bleeding (1.46 mL versus 12.02 mL) and shorter fixation duration for tracer fixation (1.56 minutes versus 5.08 minutes).

Transgender Orthopaedic Surgeon Talks About Discrimination

Last year, AAOS Now published a three-part series on perspectives from the orthopaedic LGBTQ (lesbian, gay, bisexual, transgender, and queer [or questioning]) community. As a follow-up, this article seeks to share the experience of a member of the orthopaedic community: Deborah Fabian, MD, FAAOS, is a successful orthopaedic surgeon who has transitioned; her story can serve as an educational opportunity for AAOS Now readers about transgender patients and the specific issues they must navigate. The insights can help promote a more inclusive culture within the specialty, as well as better care for patients.
