Сводка	The Global Rating of Change (GRC) Scale is a single-item, self-report outcome measure that asks patients to rate the overall change in their condition since baseline assessment. Developed by Jaeschke, Singer, and Guyatt in 1989 and published in Controlled Clinical Trials, the GRC Scale has become a fundamental method for anchor-based interpretation of change scores on clinical outcome measures, enabling clinicians and researchers to determine the minimal clinically important difference (MCID) in standardized scales.	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.
