Outcomes of Total Hip and Knee Arthroplasty Utilizing the Pittsburgh Sleep Quality Index

Brief description of study

This study is designed to evaluate patients’ sleep quality before and after a total knee and hip arthroplasty using the Pittsburgh Sleep Quality Index. Patients with end-stage osteoarthritis of the hip and knee with functional deficiencies and disrupted sleep are frequently indicated for total hip and knee arthroplasty. Additionally, patient’s expectations prior to total hip and knee replacement are an important parameter that may impact post-operative expectations, satisfaction and clinical outcomes. This study aim to determine if a patient’s sleep quality improves following hip and knee replacement surgery, and correlate these findings with scores from the Hip disability and Osteoarthritis Outcome Score (HOOS) and the Knee injury and Osteoarthritis Outcome Score (KOOS).
