Study: How Does BMI Affect Revision Rates of Cemented versus Cementless UKAs?
The Journal of Bone and Joint Surgery published a study assessing the effect of BMI on the rates of revision of cemented and cementless unicompartmental knee arthroplasty (UKA) in more than 10,000 patients. Patients were grouped according to BMI: underweight ( <18.5 kg/m 2), normal weight (18.5 to <25 kg/m 2), overweight (25 to <30 kg/m 2), and obese ( ≥30 kg/m 2). For those in the normal, overweight, and obese cohorts who received cemented UKA, revision rates per 100 component-years were 0.92, 1.15, and 1.31, respectively. For cemented UKA, the rate of revision significantly increased with increased BMI.

Study Examines Racial Disparities in Adverse Events and Readmission after ORIF of Fractures Distal to the Knee
According to retrospective database review in OTA International, Black patients had significantly higher rates of early adverse events and unplanned readmission compared with white patients following ORIF of fractures distal to the knee. Thirty-day complications and time to surgery were examined in a cohort of 1,120 Black patients who were 1:1 matched with white patients. Black patients had 1.5 times higher odds of experiencing early adverse events and 1.9 times higher odds of requiring unplanned readmission within 30 days of surgery. However, there were no significant differences observed between cohorts regarding the time to surgery.

| Study: Is There a Difference in Overall Leg Length in Patients with Unilateral Crowe Type IV Hip Dislocation?
A prognostic study in Clinical Orthopaedics and Related Research examined the overall leg length differences and consistency patterns of abnormalities in 40 patients undergoing total hip arthroplasty (THA) for unilateral Crowe Type IV hip dysplasia. Overall, limb length was not different between dislocated and non-dislocated limbs (725 mm versus 722 mm). The only consistent pattern of abnormality was a longer tibia on the dislocated side (338 mm versus 335 mm). The mean femoral neck offset of the dislocated side was shorter than that of the normal side (28 mm versus 39 mm).

| Study Investigates How the Pandemic Affected Social Media Practices of Orthopaedic Surgery Residency Programs
Current Orthopaedic Practice published an analysis evaluated how the COVID-19 pandemic influenced the social media practices of orthopaedic surgery residency programs. Social media participation was analyzed with respect to program type, location, size, geographical location, and Doximity ranking in 194 residency programs from July 2019 to December 2020. Twitter accounts increased from 28.9 percent to 44.8 percent, and Instagram accounts increased from 8.2 percent to 55.2 percent. Programs more likely to have either an Instagram or Twitter account included allopathic programs, programs with a higher Doximity Reputation Ranking, and those with more than 35 residents.

| Study Compares Outcomes of Intraoperative CT versus Conventional Radiographic Techniques for Lumbar Fusion
There were no significant differences in overall revision rates between patients who underwent intraoperative CT versus conventional radiographic techniques during lumbar fusion, according to a study in the Spine Journal. The retrospective study reviewed 132 patients who underwent intraoperative CT and 451 who underwent conventional radiographic techniques. Other than revision rates, there were no significant differences observed between groups. Additionally, there were no significant differences between cohorts regarding the three-year revision rates and 90-day complications.
