Study Compares Medial Stabilized TKA Versus Other Designs

A systematic review and meta-analysis published online in Knee Surgery, Sports Traumatology, Arthroscopy compared medial stabilized (MS) total knee arthroplasty (TKA) to other TKA designs. Twenty-two studies encompassing 3,011 patients (4,102 TKAs) met inclusion criteria. MS TKA patients had overall better Oxford Knee Scores, but Forgotten Joint Scores (FJS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Knee Society Score (KSS)-knee and function scores, and range of motion did not largely differ. In subgroup analyses, MS TKA, compared to rotating platform TKA, had significantly worse KSS-knee and WOMAC scores, but when compared to cruciate-retaining TKA, had significantly better FJS and KSS-knee score.

Study Evaluates Overall Health After Ankle Arthroplasty and Effect of PT

A retrospective study published online in Foot & Ankle International assessed patients’ overall health after total ankle arthroplasty (TAA) as well as the influence and perceived value of physical therapy (PT). Ninety-five patients who underwent TAA an average of about three years ago responded to an online survey. Most health domain scores were close to the population mean, but physical function and ability to participate in social roles and activities domain T scores remained at least one standard deviation lower than the mean. Most of the cohort received PT and thought it was beneficial. A correlation was observed between the number of PT visits and physical function T scores.

A study published online in The American Journal of Sports Medicine observed excellent 10-year patient-reported outcomes and satisfaction in adolescent patients who underwent hip arthroscopy for femoroacetabular impingement (FAI). Sixty patients (70 hips) aged younger than 18 years (mean age, 16 years; 49 hips were female) were examined. Revision arthroscopy was required in seven hips, all of which were female. Mean follow-up was 12 years, at which time patients who did not undergo revision surgery had significant improvements in Hip Outcome Score (HOS) Activities of Daily Living, HOS—Sport, modified Harris Hip Score, and 12-item Short Form Health Survey. Median satisfaction was 10 out of 10.

A systemic review and meta-analysis published online in PLOS One assessed whether the use of platelet-rich plasma (PRP) in spinal fusion surgery affected the union rate or clinical outcomes. The researchers analyzed three randomized, controlled trials (RCTs) and seven prospective cohort studies. At final follow-up, spinal fusion rates did not largely differ between the groups in the RCTs or cohort studies. In the RCT analysis, PRP was associated with significantly reduced postoperative pain, but complication rates did not largely differ between the groups. The authors noted that heterogeneity existed in the studies and called for future large RCTs to further assess PRP.

Study: How Has the COVID-19 Pandemic Affected Applicants During the 2021 Residency Match Cycle?

A study published in the November issue of the Journal of the AAOS: Global Research and Reviews ® ascertained the effect of the COVID-19 pandemic on rising fourth-year medical students’ plans to apply to orthopaedic surgery residency. Overall, 462 students were planning to apply to residency in orthopaedic surgery; women, compared to men, were less likely to apply due to the pandemic (14.9 percent versus 5.5 percent), as were Black students compared to white students (169 percent versus 8.8 percent). Most students said they had “somewhat” or “many” fewer opportunities (88.9 percent) to gain enough exposure to the specialty to make their decision.
