President’s Message: ‘Make No Little Plans’
The past two years have been a challenge like no other we have faced. Yet through it all, we came together as leaders to advance the field of musculoskeletal health. Thank you for your continued commitment to our profession and engagement with AAOS. We held a safe and successful meeting in 2021 and are excited to build on that momentum to welcome you to Chicago March 22 to 26 for an even bigger and more comprehensive experience of orthopaedic education, innovation, and collaboration. Register online today. Legendary Chicago architect Daniel Burnham famously said, “Make no little plans.” The spirit and ambition in these words live in the Annual Meeting that the Academy’s volunteers and supporting staff have planned for Reaching New Heights in March at McCormick Place Convention Center, on the lakefront of Chicago where Burnham’s legacy can still be seen in the surrounding parks and architecture. Please make plans to attend the 2022 Annual Meeting. I look forward to seeing everyone in Chicago.

Favorable Outcomes with Robotic-arm–assisted versus Manual Knee Arthroplasty
A retrospective study published in the Journal of the AAOS ® reported that robotic-arm–assisted knee arthroplasty (RA-KA) was associated with favorable outcomes and reduced complications compared with manual KA. A matched cohort analysis was conducted for manual KA, computer-assisted (CA) KA, and RA-KAs from the National Inpatient Sample (2008-2018). RA- and CA-KA were associated with shorter length of stay and reduced in-hospital implant complications compared with manual KA. Specifically, RA-KA was associated with reduced nonhome discharge rates and fewer nonmechanical complications. RA-KA use increased from <0.1 percent to 4.3 percent from 2008 to 2018.

| Study: 10-year Incidence of Mechanically Assisted Crevice Corrosion in Uncemented THA
At 10-year follow-up, at least 22 percent of 162 contemporary uncemented, nonrecalled total hip arthroplasties (THAs) demonstrated mechanically assisted crevice corrosion (MACC), and 59 percent of patients with MACC had undergone revision, according to a study published online in The Journal of Arthroplasty. Of the initial cohort, 109 hips were available at final follow-up. Thirty-five hip implants had cobalt levels of ≥1 ppb, the cutoff for MACC. Forty-seven percent of MACC cases were symptomatic, with adverse local tissue reactions in 16 of 30 patients (53 percent) who underwent MRI.

| Study: Factors Impacting ASES Scores after Arthroscopic Latissimus Dorsi Tendon Transfer
Pseudoparalysis and acromiohumeral interval (AHI) reversibility were the most important independent prognostic factors for achieving patient-acceptable symptom state (PASS) values for the American Shoulder and Elbow Surgeons (ASES) score after arthroscopic-assisted latissimus dorsi tendon transfer for the management of massive rotator cuff tears. These findings were reported in a retrospective study of 42 patients, published online in Arthroscopy. At a mean follow-up of 27.8 months, patients demonstrated significant improvements in ASES and Constant-Murley scores from baseline. The cutoff value for AHI reversibility to predict PASS was 4.0 mm.

| Study: Reduced Knee Function Symmetry during the Triple-hop Test after ACLR in Athletes
During the triple-hop test after ACL reconstruction (ACLR) in athletes, symmetry regarding hop distance may hide asymmetries in knee function, according to a study published online in the American Journal of Sports Medicine. Three-dimensional motion analysis was conducted in 24 male athletes upon return to sport clearance. Despite high levels of limb symmetry in distance hopped (97 percent) and knee work absorption symmetry in the second rebound and third landing (80 percent), athletes only achieved 51 percent and 66 percent limb symmetry for knee work generation in the first and second rebounds, respectively. These differences were more prominent during work generation than absorption.

| Study: Utility of Routine Radiography in Pediatric Osteoarticular Infection
A retrospective study published online in the Journal of Pediatric Orthopaedics reported that serial radiographic follow-up for pediatric osteoarticular infections rarely altered management in cases without other concerning clinical signs or symptoms (fevers, swelling, etc.). In total, 131 children were evaluated, and 287 routine radiographs were collected (88 percent of radiographs). Based on routine imaging, two negative sequelae (0.7 percent) were identified. The number needed to screen (NNS) to identify negative sequelae was 143. Reactive radiography led to a 5.1 percent detection rate of negative sequalae (NNS = 20 radiographs).
