Study Analyzes Effect of Preoperative Staphylococcal Colonization Status on Complications in TJA Patients
In a retrospective analysis of 711 patients undergoing total joint arthroplasty (TJA), those who tested positive for methicillin-resistant staphylococcus aureus (MRSA) had longer lengths of stay and higher rates of readmission. The study, published in the Journal of Arthroplasty, aimed to evaluate the complications associated with patients’ preoperative staphylococcal colonization status postsurgery. Compared against patients who were methicillin-sensitive staphylococcus aureus (MSSA)-positive and MSSA/MRSA-negative, those who were MRSA-positive also had higher rates of all-cause, aseptic, and septic revisions.
Does Severity of Glenohumeral OA Correlate with Improvements in Patient-reported TSA Outcomes?
Clinical Orthopaedics and Related Research published a study investigating whether preoperative radiographic severity of glenohumeral osteoarthritis (OA) is associated with improvement in pain and function after anatomic total shoulder arthroplasty (TSA). Overall, 206 patients were included in the analysis. Researchers evaluated the severity of OA based on the modified Samilson-Prieto and Walch classification and assessed patient-reported outcomes via the American Shoulder and Elbow Surgeons (ASES) score and visual analog scale. Patients with less severe OA were less likely to achieve the minimum clinical important difference for the ASES score (22 percent versus 4 percent).
Study: Did the COVID-19 Lockdown Affect Rates of Cyclops Lesions after ACLR in Patients Who Underwent Self-rehabilitation?
A retrospective study in the Orthopaedic Journal of Sports Medicine analyzed the rate of cyclops lesions after ACL reconstruction (ACLR) in patients who underwent self-rehabilitation during the COVID-19 lockdown period. Seventy-two patients were identified and matched with a control group who completed postoperative supervised rehabilitation following the lockdown period. The outcome measurements were Knee Documentation Committee (IKDC) and Lysholm scores. Mean IKDC and Lysholm scores in the COVID-19 group were 80.3 and 86.6, respectively. The rate of cyclops lesions was significantly lower in the control group (1.4 percent) compared with the COVID-19 group (11.1 percent).
Study: More Malleoli and High BMI Associated with Worse PROs after Ankle Fractures Involving the Posterior Malleolus
Foot & Ankle Orthopaedics published a retrospective cohort study assessing the risk factors for poor patient-reported outcomes (PROs) in patients with fractures involving the posterior malleolus. Fracture characteristics including the Lauge-Hansen and Haraguchi classifications and posterior malleolar fragment size were collected from 122 patients, and Patient-reported Outcome Measurement Information System (PROMIS) scores were recorded pre- and one year postoperatively. Worse PROMIS Physical Function, Global Physical and Mental Health, and Depression scores were seen in fractures with the involvement of more malleoli, and high BMI was associated with worse PROMIS Physical Function, Pain Interference, and Global Physical Health scores.
Study Compares Outcomes after Exposed versus Buried Intramedullary Fixation in Acute Pediatric Monteggia Fractures
A retrospective review of pediatric patients with acute Monteggia fractures in the Journal of Pediatric Orthopaedics found that exposed intramedullary fixation yielded comparable clinical outcomes but higher rates of complications when compared against buried fixation. Patients’ complications, cast duration, time to fracture union, time to hardware removal, and range of motion were collected from patient charts. The cast time after surgery was 39 days in the buried intramedullary fixation group and 37 days in the exposed group. The time to fracture union was also similar between groups (37 days versus 35 days).
The Power of Registry Data Keeps Gaining Momentum: A Look Back on 2022 for the AAOS Registry Program
AAOS has invested significant time and resources to deliver a comprehensive Registry Program and provide a reliable source of actionable data to inform practice decisions for orthopaedic procedures. The momentum experienced this past year—from collecting a decade’s worth of hip and knee arthroplasty procedures to seeing registry data in nearly three dozen published papers—has led to growth and progress for the Registry Program. There are now five AAOS registries with more than 3.3 million procedures from more than 12,000 surgeons and 1,400 participating sites.
AAOS Board of Directors Approves Two New AUC for Shoulder Pathologies
During their March meeting, the AAOS Board of Directors approved the Appropriate Use Criteria (AUC) on the Treatment of Shoulder Osteoarthritis with Intact Rotator Cuff and Severe Glenoid Retention and the AUC on Humeral Component Design during Primary Anatomic Total Shoulder Arthroplasty. Both AUC were based on consensus recommendations from the 2020 Clinical Practice Guideline on the Management of Glenohumeral Joint Osteoarthritis.
