(103) The Impact of Self-Reported Sleep Disturbances on Preoperative Experimental Pain Sensitivity and Knee Arthroplasty Outcomes

Approximately 18% of patients undergoing lower extremity joint arthroplasty fail to significantly improve following arthroplasty. We previously demonstrated that higher levels of fibromyalgia (FM) symptoms ( “FMness”) prior to surgery are associated with less postoperative improvement. Sleep disturbances, which are a core symptom domain in FM, are present in greater than 90% of chronic pain patients. Here, we consider the impact of self-reported sleep disturbances on knee arthroplasty outcomes six m onths after surgery (n=74, 54% female), and on psychophysical pain sensitivity in a subset of these patients preoperatively (n=43).
