“…TKA and total hip arthroplasty revisions and reoperations are also modeled with AI/ML algorithms in some studies, [ 15 , 16 , 21 , 64 ] as well as hospital readmissions [ 20 , 21 , 26 , 27 ]. In the postoperative period, AI/ML tools offer surgeons the ability to predict patients’ outcomes after surgery, including functional outcomes and PRO scores [ 14 , 32 , 33 , 43 , 45 , [48] , [53] , [54] , [57] , [58] , [59] , [61] ]. Postoperative pain has also been shown to be predicted with AI/ML, [ 43 , 53 , 56 , 55 ] including identification of patients at high risk for prolonged postoperative opioid prescriptions.…”
