สรุป	The Hip Outcome Score (HOS) is a 29-item patient self-report instrument designed to measure symptoms, functional limitations, and activity restrictions in individuals with hip disorders. Originally developed and published by Philippon, Kelly, and Martin in 2006 in Arthroscopy, the HOS has become the standard outcome measure in hip arthroscopy, hip preservation surgery, and hip rehabilitation research, providing comprehensive assessment of pain, function in daily activities, and return-to-sport capability in hip-specific populations.	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.
