According to news reporting originating from Brookl yn, New York, by NewsRx correspondents, research stated, “Robotic-armassisted u nicompartmental knee arthroplasty (UKA) is an excellent solution for patients su ffering from single-compartment knee arthritis. While outcomes tend to be favora ble for UKAs, revision operations, commonly due to component malpositioning and malalignment resulting in accelerated wear, are a major concern.” Our news editors obtained a quote from the research from Maimonides Medical Cent er, “Intraoperative technologies, such as robotic assistance, can help better en sure that implants are positioned based on a patient’s specific anatomy and mech anical physiology. However, long-term survivorship and patientreported satisfac tion with robotic-assisted UKAs are limited. Therefore, the purpose of this stud y was to assess the 10-year outcomes of patients who underwent robotic-arm-assis ted unicompartmental knee arthroplasty. Specifically, we evaluated: 1) 10-year s urvivorships; 2) patient satisfaction scores; and 3) re-operations. From a singl e surgeon and single institution, 185 patients who had a mean age of 65 years (r ange, 39 to 92) and a mean body mass index of 31.6 (range, 22.4 to 39) at a mean of 10 years follow-up were evaluated (range, 9 to 11). For all patients, the sa me robotic-assistive device was utilized intraoperatively, and all patients unde rwent standardized physical therapy and received standardized pain control manag ement. Then 10-year survivorships with Kaplan-Meir curves, patient satisfaction evaluations with a 5-point Likert scale, and re-operations were assessed as prim ary outcomes. Overall implant survivorship was 99%, with only two p atients requiring revision surgery. There was one patient who was converted to a total knee arthroplasty, while the other patient underwent polyethylene exchang e at 5 weeks for an acute infection with successful implant retention. Overall, 97% of the patients were satisfied with their postoperative outcom es, with 81% of patients reporting being very satisfied. There wer e two other patients who required arthroscopic intervention: one to remove a cem ent loose body, the other to remove adhered scar from the fat pad and the anteri or cruciate ligament. This study is one of the first to provide longer-term (mea n 10-year) survivorship and patient-reported satisfaction outcomes for robotic-a ssisted UKA patients. These data show strong support for utilizing this surgical technique, as nearly all patients maintained their original prostheses and repo rted being satisfied after a mean of 10 years.”
