A Nomogram Model for Predicting Prolonged Postoperative LOS After Total Knee Arthroplasty in Osteoarthritis Patients
The model, based on age, knee flexion range of motion, operation time, and American Society of Anesthesiologists classification, provides a practical tool for clinicians to assess individual risks, optimize resource allocation, and improve patient outcomes. It is important to note that this was a single-center, retrospective study, and further validation in multi-center, prospective cohorts is recommended to confirm its generalizability.
