Machine learning using preoperative patient factors can predict duration of surgery and length of stay for total knee arthroplasty
Background Total knee arthroplasty (TKA) is one of the most resource-intensive, high-
volume surgical procedures. Two drivers of the cost of TKAs are duration of surgery (DOS) …
