YES! The AAOS 2021 Annual Meeting Is On!
I want to take this opportunity to remind everyone that the Annual Meeting is indeed taking place in San Diego in just a couple of weeks, and we very much look forward to seeing you there! AAOS is committed to hosting a safe in-person event for our members, staff, exhibitors, and industry partners, including requiring proof of vaccination or negative COVID-19 test as well as a requirement for all attendees to wear masks. Visit the Health & Safety Resources webpage for additional information, and register today!

Study: Low Failure Rates after Open Subpectoral Biceps Tenodesis for SLAP Tears
Compared to arthroscopic repair (AR), open subpectoral biceps tenodesis (BT) achieved similar outcomes and fewer revisions for the treatment of symptomatic isolated superior labrum anterior-to-posterior (SLAP) tears, according to a study published online in Arthroscopy. In total, 103 patients (BT, n = 29; AR, n = 74) were followed for 60 months. Functional assessments at last follow-up and rates of return to play were comparable. Nine patients in the AR group (11.5 percent) required revision, compared to zero patients in the BT group.

| Study: Does AR-guided Nailing for Trochanteric Fracture Improve Tip-apex Distance?
A study published online in Injury evaluated whether augmented reality (AR)–guided cephalomedullary nail positioning in trochanteric hip fracture fixation improves tip-apex distance (TAD). Eighty-two patients (AR, n = 41) were included. The Stryker ADAPT for Gamma3 navigation system was used. TAD in the AR and control groups were 14.45±3.68 mm and 16.41±3.78 mm, respectively. More AR-guided nails were in the center-center position within the femoral head than in the control group. Operative and fluoroscopy time and radiation dose were comparable overall. The authors noted, however, that overall TAD improvement with ADAPT navigation likely does not reach clinical significance.

| Study: Impact of Anatomic versus Dome Patella on Kinematics after PS TKAs
A study published online in The Journal of Arthroplasty evaluated the kinematics of a fixed-bearing (FB) versus mobile-bearing (MB) posterior-stabilized (PS) implant in total knee arthroplasty (TKA), specifically focusing on the impact of anatomic and medialized dome patellar components. Forty patients were included (anatomic, n = 20; dome, n = 20). Within these groups, 10 patients each received a FB or MB implant. The MB-anatomic group achieved greater lateral condyle translation, axial rotation, and range of motion compared to the FB-anatomic group. Kinematics were comparable among the overall dome patella group.

| Randomized Study Compares Arthroplasty versus Fusion for Cervical Radiculopathy
Anterior cervical disc arthroplasty and standard discectomy with fusion for the treatment of cervical radiculopathy both lead to substantial clinical improvements at five years, according to a randomized study published in JAMA Surgery. In total, 136 patients were randomized 1:1 to arthroplasty or fusion, and 114 participants completed five-year follow-up. Patients in both groups showed significant improvement in Neck Disability Index scores, but between-group differences were not significant. There were no significant differences in changes in arm pain, neck pain, quality of life scores, revision rates, and adjacent segment disease between groups.

Advances in Next-generation Sequencing Will Significantly Impact the Diagnosis of Orthopaedic Infections
As genomic sequencing becomes more accessible and affordable, its role in diagnosing infection is growing across medical specialties. In orthopaedic surgery, research has shown that next-generation sequencing is more sensitive, specific, and cost-effective than traditional culture. These benefits are especially important in orthopaedics, as hardware-related infections are daunting complications and timely and accurate diagnosis are of the essence. This article outlines the history of genomic sequencing, its pivot to application in infections, and more specifically its utility in the diagnosis of periprosthetic joint infections.

AAOS Board of Directors Approves Endorsement of Five AAHKS CPGs of Anesthesia and Analgesia in TJA
The AAOS Board of Directors has endorsed the final five of nine Clinical Practice Guidelines (CPGs) on perioperative analgesia and anesthesia following total joint arthroplasty (TJA), produced by the American Association of Hip and Knee Surgeons (AAHKS) in collaboration with AAOS, the American Society of Regional Anesthesia and Pain Medicine, The Hip Society, and The Knee Society. This second section covered regional nerve blocks for both total hip and total knee arthroplasty, corticosteroids, periarticular injections, and ketamine use following TJA.
