Study: Increased Periprosthetic Infection, Fracture with Noncemented versus Cemented TKA
Noncemented total knee arthroplasty (TKA) for osteoarthritis is associated with higher rates of periprosthetic joint infection (PJI) and periprosthetic fracture at two years postoperatively compared with cemented TKA, according to a retrospective study published in the Journal of the AAOS ®. The researchers identified 203,574 patients from a national database (noncemented, 3.2 percent). Rates of 90-day medical complications were similar regardless of procedure type. PJI rates were significantly higher in noncemented TKA at 90 days, one year, and two years, and periprosthetic fracture was higher at one and two years. Aseptic loosening did not differ between groups.

Study: Age and Sex Are Associated with Revision within Six Months of THA
A retrospective study published online in The Journal of Arthroplasty reported significant differences in causes for total hip arthroplasty (THA) revision according to patient gender and age, as well as time from surgery. Data on 79,205 THAs, including 1,433 revisions, were analyzed. Fifty-three percent of revisions occurred within six months, primarily for fracture, instability, and infection. Age and sex were significantly associated with revision, with higher rates among older women compared with young men.

| Study: Smoking, Prior Surgery Are Associated with Improvement in PROMIS Scores after Arthroscopic RCR
A study published online in the Journal of Shoulder and Elbow Surgery found that most patients improved after arthroscopic rotator cuff repair (RCR) at levels that exceeded the established minimal clinically important difference (MCID) for Patient-reported Outcome Measure Information System (PROMIS) scores. In total, 168 patients were included. An MCID was achieved in 81 percent of patients for PROMIS Upper Extremity scores, 65 percent for Pain Interference, and 55 percent for Depression scores. Smoking status and prior shoulder surgery were associated with rates of MCID for Upper Extremity and Pain Interference scores.

| Study: Occupational Musculoskeletal Injuries in the United States since 1992
A study published online in Injury reported trends in workplace-related musculoskeletal (MSK) injuries between 1992 and 2018 using data from the U.S. Bureau of Statistics. During the overall period, there were 1.41 upper extremity injuries, 0.88 lower extremity injuries, and 1.57 trunk injuries per 1,000 employed people. Incidence of occupational MSK injuries trended downward over time, with the greatest reduction occurring in the manufacturing sector. The healthcare sector had the smallest reduction in occupational MSK injuries of the sectors analyzed.

| Study: Insurance, Socioeconomic Status Are Not Associated with Severity of Pediatric Slipped Capital Femoral Epiphysis
A retrospective study published in the Journal of Pediatric Orthopaedics found that insurance status and socioeconomic status were not associated with delays in diagnosis of pediatric slipped capital femoral epiphysis (SCFE) or in severity of SCFE. All patients treated for SCFE at a single center between 2010 and 2021 were evaluated (n = 142). Patients were aged an average of 12.2 years, with an average symptom duration of 4.5 months. Female sex, symptom duration of <3 months, and white race were associated with moderate SCFE, while insurance status and residential area deprivation index were not.
