Tóm tắt	The Lysholm Knee Scoring Scale is an 8-item knee outcome instrument developed by Swedish orthopedic surgeons Lysholm and Gillquist in 1982 to evaluate knee ligament surgery results. Published in the American Journal of Sports Medicine, the Lysholm Scale was among the first validated knee outcome measures and remains widely used in clinical practice and orthopedic research, particularly in studies of anterior cruciate ligament injuries and knee ligament reconstruction.	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.
