Muhtasari	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 Lower Extremity Functional Scale (LEFS) is a 20-item patient self-report instrument designed to assess functional limitations in individuals with lower extremity musculoskeletal disorders. Developed by Binkley, Stratford, Lott, and Riddle in 1999 and published in Physical Therapy, the LEFS provides a validated, general lower-extremity outcome measure applicable across diverse pathologies (knee, ankle, hip, foot injuries and conditions), making it particularly valuable in physical therapy and rehabilitation settings.
