Treating Sleep Disorders After Total Hip and Total Knee Arthroplasty.

Disorders of sleep are common after total hip and knee arthroplasty and may contribute to patient dissatisfaction and poorer outcomes in the early postoperative period. Multiple factors contribute to sleep disorders, including poorly controlled pain, opioid medication, perioperative stress, and anxiety. Both pharmacologic and nonpharmacologic methods have been used for perioperative sleep disorders, but there is no consensus on the optimal treatment.
