Study: Re-tear Size and Female Sex are Associated with Arthroscopic RCR Outcomes
Progressed rotator cuff re-tear size was significantly associated with treatment failure after arthroscopic rotator cuff repair (RCR), according to a study of 117 patients published online in the Journal of Shoulder and Elbow Surgery. Treatment failure was defined as achievement of patient acceptable symptomatic state values for various functional assessments. The failure rate was 25.6 percent at a mean follow-up of 37.5 months. Seventeen re-tears (14.5 percent) occurred. Female sex was significantly associated with failure risk. Larger re-tear size, but not re-tear alone, was significantly associated with failure.
Study Investigates Risk Factors of Metachronous PJI in TJA
In total joint arthroplasty (TJA), risk of metachronous periprosthetic joint infection (PJI) is associated with inflammatory response syndrome, ≥3 stages of resection, and infection via methicillin-resistant Staphylococcus aureus, according to a study published online in The Journal of Arthroplasty. All cases of PJI (n = 96) at a single center between 1994 and 2020 were assessed. Average follow-up was 11.2 years. Overall, 19.79 percent developed metachronous PJI after an average of 789.84 days. The causative pathogen was the same in both cases in 63.16 percent.
Study Compares Maturation in BTB versus Hamstring Tendon Autograft for ACLR
A study published online in Knee Surgery, Sports Traumatology, Arthroscopy found superior two-year graft maturation for bone-patellar tendon–bone (BTB) versus double-bundle hamstring tendon (HT) autograft in ACL reconstruction (ACLR). Seventy-five patients (BTB, n = 30; HT, n = 45) underwent second-look arthroscopy and MRI after one and two years, respectively. Maturation was significantly greater in the BTB versus HT group. There were significant between-group differences in MRI signal/noise quotients. Clinical scores were comparable overall. The BTB group showed significantly reduced knee laxity compared to the HT group.
Study: Conversion from Ulnar Head Prosthesis to Distal Radioulnar Joint Arthroplasty
A study published online in the Journal of Hand Surgery found that conversion from a painful and unstable ulnar head prosthesis to a semi-constrained distal radioulnar joint arthroplasty improved pain and function with low rates of revision. Eleven cases (n = 10) were assessed. Median time to conversion was 47 months. Seven patients demonstrated improved postoperative pain severity. Grip strength and forearm pronation-supination were comparable pre- and postoperatively. One patient required prosthesis removal due to aseptic loosening at five years, and two nondisplaced periprosthetic fractures were treated via cast immobilization.
Study: BMI Is Associated with Odds of Unstable Ankle Fracture with Syndesmosis Disruption
A study published online in BMC Musculoskeletal Disorders found that being overweight is associated with an increased risk of ankle fracture with Danis-Weber fracture type B or C (syndesmosis disruption and instability). The researchers investigated the impact of overweight, obesity, and osteoporosis on ankle fracture risk in 108 patients (compared to 199 controls). Higher BMI was associated with a stepwise increase in odds of ankle fracture and was also associated with higher risk of type B or C fracture. Osteoporosis did not significantly increase odds of ankle fracture.
AAOS members will soon receive the print edition of the August issue of AAOS Now, but the electronic edition is already available on the AAOS Now website. This month’s issue spotlights some of the exciting offerings at the upcoming AAOS 2021 Annual Meeting in San Diego, plus mental health in athletes, the latest guidelines for perioperative pain management, and more.
