Shared decision-making provides patients a measure of autonomy in making choices for their health and their future. Patient-reported outcome measures (PROMs) use clinically sensitive and specific metrics to evaluate a patient's self-reported pain, functional ability, and mental state. We conducted a study to create an evidence-based clinical decision-making tool. ⋯ Preoperative Veterans RAND 12-Item Health Survey (VR-12) mental health component summary (MCS) scores predicted self-reported pain and function (Ps < .001) 1 year after surgery. In these models, preoperative VR-12 MCS score was the most predictive PROM for 1-year postoperative VAS pain score (ω2 = .023) and 1-year postoperative ASES Function score (ω2 = .029). Together, a patient's preoperative VAS pain score, ASES Function score, VR-12 MCS score, age, sex, and type of arthroplasty can provide significant predictive value that may aid in setting appropriate expectations for pain and function 1 year after surgery.
