Morbidly obese patients undergoing robotic-assisted hip replacement face a dramatically increased likelihood of prosthetic joint infections (PJIs). A researcher at the meeting in New Orleans said the risk of infection rises sharply in these patients compared to others. The study focused on patients from a national registry. The main finding confirms a significant increase in the incidence of PJI in combined morbid obesity and robotic hip arthroplasty. These infections are a serious complication after surgery. The research emphasizes the specific risk in this group of patients.
