خلاصه	The Oxford Knee Score (OKS) is a brief, validated self-report questionnaire developed by Murray and colleagues at the University of Oxford in 1998 to measure outcomes following knee replacement surgery. The OKS comprises 12 items assessing knee pain, knee-related functional limitations, and quality of life in patients undergoing total knee arthroplasty. It is the primary patient-reported outcome measure for knee replacement in international orthopedic research and clinical practice.	The Brief Pain Inventory (BPI) is a concise, validated self-report instrument developed by Cleeland and Ryan beginning in 1994 to measure the severity and functional impact of pain in patients with cancer and chronic pain conditions. The BPI-Short Form comprises 11 items assessing pain severity and interference with daily activities, enabling rapid multidimensional pain assessment across diverse clinical populations.
