Study Investigates Incidence and Predictors of Hip Dislocation within Two Years of THA

According to a study published in the Nov. 1 issue of the Journal of the AAOS ®, 2.3 percent of patients undergoing total hip arthroplasty (THA) for osteoarthritis experienced hip dislocation within two years. Researchers compared characteristics of 155,185 patients with dislocation versus control subjects. Dislocation was associated with <65 years of age, female sex, BMI <20, higher Elixhauser Comorbidity Index, cemented prosthesis, and metal-on-poly or metal-on-metal implants. Revision surgery occurred within two years of THA for 45.6 percent of patients experiencing dislocation compared with 1.8 percent of those who did not.

Study: Survivorship of 500 Cementless TKAs in Patients Aged under 55 Years

A retrospective study published in The Journal of Arthroplasty analyzed the survivorship and rate of revision of 500 cementless total knee arthroplasties (TKAs) in patients aged <55 years. The all-cause and aseptic survival rates were 98.4 percent and 99.2 percent, respectively, at a median follow-up of 10.7 years. Of patients undergoing revision, four had infections, two had stiffness, one had aseptic loosening of the tibial component, and one had a patella that was resurfaced for anterior knee pain.

The Journal of Shoulder and Elbow Surgery published a retrospective study online investigating the association between radial head diameter and radial head arthroplasty revision. Patient demographics, comorbidities, implant type and head diameter, and indications for revision were obtained from 405 patients. Radial heads sized 26 mm had 7.7-times greater odds of revision compared with radial heads sized 18 mm. Outcomes and complications were similar between the two main implants used. There was a significantly higher reoperation rate for terrible triad (18.4 percent) versus isolated injuries (10.4 percent).

Foot & Ankle International published a prospective cohort study evaluating the outcomes of the application of noninvasive skin expansion strips (NSESs) after total ankle arthroplasty (TAA) through the anterior approach. Forty-one patients treated with NSESs and 41 patients treated without NSESs were included. The primary outcomes included additional clinic visits for wound assessment or suture removal, superficial wound complication, and deep infection. Patients with NSESs had significantly lower clinic visits after surgery (15 percent versus 49 percent). No deep infections occurred in either group; however, patients with NSESs had significantly lower rates of wound complications.

Medical Groups Support Lawsuit against the Government over Surprise Billing Rule

Several physician groups, including AAOS, are supporting a second lawsuit brought by the Texas Medical Association against the federal departments responsible for implementing the No Surprises Act. In an amicus brief filed recently with a federal court in Texas, the groups warned that the August 2022 final rule on the Qualifying Payment Amount used to resolve unanticipated medical bills creates a de facto out-of-network rate which governs the relationship between health insurers and providers, greatly diminishing patient access to care. A second amicus brief was filed earlier this year for a separate lawsuit, led by the American Medical Association and the American Hospital Association, which was later dismissed.
