요약	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 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.
