摘要	The Marx Activity Rating Scale (MARS) is a 4-item patient-reported instrument that quantifies the frequency of high-demand athletic activities performed in the past four weeks. Developed by Marx and colleagues in 2001 and published in the American Journal of Sports Medicine, the MARS focuses specifically on quantifying participation in running, cutting, decelerating, and pivoting—the high-impact, multi-directional activities that demand the most from the knee and ankle. The MARS is widely used in orthopedic research to classify patients by activity level and to assess return to activity following surgery.	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.
