AAOS Diversity Town Hall Spotlights Recent AAOS Initiatives
On Monday, June 27, at 7 p.m. CT, tune in for a discussion of AAOS activities in support of the Strategic Plan, specifically the Diversity Dashboard and AAOS IDEA Grant Program™. Led by AAOS leadership and the Diversity Advisory Board, this town hall is intended to provide the membership with an update on AAOS diversity activities and an avenue for AAOS members to share feedback.
Study: Machine Learning Algorithm Successfully Predicts Early Revision after THA
A study published in the June 1 issue of the Journal of the AAOS ® reported “excellent” discrimination for a machine learning model to predict early revision (<2 years from index surgery) after primary total hip arthroplasty (THA). Data from 7,397 patients were included. Early revision was required in 6.6 percent of patients. Six machine learning algorithms were developed. Charlson Comorbidity Index, BMI >35, and depression were the strongest predictors of early revision. All six models achieved an area under the curve of >0.80 and demonstrated excellent calibration and decision curve analyses.
Study: Patient Cohorts in TJA RCTs Are Similar to the National Patient Population
A study published online in The Journal of Arthroplasty reported that patient cohorts in randomized controlled trials (RCTs) for total joint arthroplasty (TJA) in the United States are similar to the TJA patient population at large. Patient data from 153 RCTs were compared with data gleaned from the National (Nationwide) Inpatient Sample and the National Surgical Quality Improvement Program databases. The average age was 65 years in the RCT group and 67 years in the nationwide group, and the average BMI was 30.8 and 31.9, respectively. Effect sizes for age, BMI, sex, ethnicity, smoking, and diabetes were small or very small between groups.
Study: Two-year Outcomes of Arthroscopic Revision Rotator Cuff Repair
A study published online in The American Journal of Sports Medicine reported frequent but small retears after arthroscopic revision rotator cuff repair. However, retears were not associated with poorer function. One hundred patients were included. Follow-up occurred at six months and 24 months postoperatively. All clinical scores were improved from preoperative levels at final follow-up. Retear occurred in 51.8 percent, and 12.6 percent of patients required revision. Previous open rotator cuff repair, involvement of the subscapularis, moderate to severe chondral lesions, and medial cuff failure were associated with poorer Subjective Shoulder Value scores at two years.
Study: Percutaneous Fixation with Cemented K-wire Frame for Distal Radius Fracture
A study published online in BMC Musculoskeletal Disorders reported that percutaneous fixation with a cemented K-wire frame was safe and effective for the treatment of types A2, A3, and B1 distal radius fractures. Seventy-eight patients were included (A2, n = 10; A3, n = 46; B1, n = 22). All patients achieved bone healing at a mean of 4.5 weeks. Follow-up was an average of 27 months. The mean Mayo Wrist Score at follow-up was 97, and 66 patients achieved an “excellent” score (90 to 100). Average patient satisfaction was also high.
‘Safe Zones’ Can Reduce Iatrogenic Injury Risk to the Sural Nerve
A team of researchers has identified certain “safe zones” of the ankle that surgeons can use as guides during orthopaedic foot and ankle procedures to reduce the risk of iatrogenic injury to the sural nerve. The sural nerve is at risk of injury during a variety of common surgical approaches given the nerve’s location and variation. Injury to the cutaneous nerves in the ankle may consequently result in symptomatic neuroma formation and chronic pain, paresthesias, or sensory deficits.
June Podcast Episodes Feature Tipton Leadership Award Winner and Conversation on Registry Advocacy
In the latest episode of the AAOS Career Podcast, 2022 AAOS Tipton Leadership Award winner Andrew W. Gurman, MD, FAAOS, talks about creating change through knowledge, position, and authority in orthopaedics. The June episode of the AAOS Advocacy Podcast features a conversation on the role that advocacy plays in advancing the quality of musculoskeletal care through the AAOS family of registries.
