Study Identifies Risk Factors for Shoulder PJI
According to a study of 998 patients undergoing shoulder arthroplasty in the Journal of Bone and Joint Surgery, younger patients and those undergoing procedures other than anatomic total shoulder arthroplasty (TSA) were at a higher risk of shoulder periprosthetic joint infection (PJI). Patient and surgical characteristics were compared between patients who developed shoulder PJI and those that did not. Overall, 20 patients developed shoulder PJI. Patients with PJI were also more likely to be male, have commercial insurance, and consume alcohol. Procedures such as TSA and hemiarthroplasty trended toward a higher risk of PJI.

Assessing ChatGPT’s Performance on Orthopaedic Board Examination
Clinical Orthopaedics and Related Research published a study investigating whether the artificial intelligence (AI) model ChatGPT can pass the American Board of Orthopaedic Surgery examination. Four hundred publicly available questions based on the Orthopaedic In-Training Examination ® were randomly selected, and the mean scores of residents who took the test over a five-year period were compared with ChatGPT’s score. ChatGPT correctly answered 47 percent of the time and scored in the 40th percentile for postgraduate year (PGY) 1 and the eighth percentile for PGY2. ChatGPT’s performance decreased as question taxonomy level increased.

| Study Compares Single, Double, and Triple PRP Doses to Treat Knee OA
Arthroscopy published a systematic review and meta-analysis comparing the efficacy of a single dose of platelet-rich plasma (PRP) with multiple doses of PRP therapy in the treatment of knee osteoarthritis (OA). Seven randomized controlled trials (RCTs), which included 575 patients, were analyzed. Visual analog scale (VAS), Western Ontario and McMaster Universities Arthritis Index scores, and adverse events were examined. Significantly better VAS scores were observed in single-dose PRP injections compared against triple dose PRP therapy after one year; however, no significant differences were observed between single- and double-dose PRP after one year.

| Comparative Analysis of Total Ankle Arthroplasty and Ankle Arthrodesis for Hemophilic Arthropathy
A systematic review in Foot and Ankle International assessed total ankle arthroplasty (TAA) as an alternative to ankle arthrodesis (AA) in patients with hemophilic arthropathy. Twenty-one studies met the criteria for analysis. TAA and AA yielded comparable outcomes in terms of the enhancement of American Orthopaedic Foot & Ankle Society hindfoot-ankle score, visual analog scale pain scores, and the mental and physical component summary scores of the 36-item Short Form Health Survey. The rates of complications were also similar. Range of motion increased following TAA.

| Study Investigates Indocyanine Green Staining Rate in Bone and Soft-tissue Tumors
A study examining the rate of indocyanine green (ICG) staining of bone and soft-tissue tumors found an overall tumor stain rate of 88 percent. The study was published in the Bone & Joint Journal. Sixty minutes presurgery, ICG was administered via IV at a dose of 2 mg/kg. The stain rate and signal-to-background ratio of each tumor were subjected to post hoc analysis. For malignant and benign tumors, the stain rate was 94 percent and 82 percent, respectively. After en bloc resection, the accuracy rate significantly decreased compared with piecemeal resection, with rates of 16 percent and 71 percent, respectively.
