Sammanfattning	The Patient-Specific Functional Scale (PSFS) is a unique, individualized outcome instrument that captures patient-identified functional limitations and tracks change in those specific activities. Developed by Stratford and colleagues in 1995 and published in Physiotherapy Canada, the PSFS revolutionized patient-centered assessment by allowing each patient to identify and rate the three to five activities most important to them, rather than answering predetermined questions. This approach ensures relevance and maximizes the instrument's sensitivity to clinically meaningful change in patient-valued outcomes.	The IKDC Subjective Knee Form is an 18-item patient self-report instrument that measures knee function and symptoms in individuals with various knee conditions. Developed by the International Knee Documentation Committee in 2001 and published in the American Journal of Sports Medicine, it has become the gold standard for assessing knee-specific outcomes across diverse populations, from athletes returning to sport after anterior cruciate ligament injury to patients with osteoarthritis or meniscal pathology.
