What are the cutoff scores for a problematic knee on the Sport/Rec subscale for KOOS?

• A. Sport/Rec <85.0
• B. Sport/Rec <92
• C. Sport/Rec <95
• D. Sport/Rec <85

Answer: (D)

KOOS Sport/Rec ranges from 0 to 100, with higher scores meaning fewer problems during sports and recreational activities. A cutoff of 85 is used to flag clinically meaningful impairment: when the score falls below 85, it indicates noticeable difficulty in sport- and recreation-related tasks (like running, jumping, pivoting, stairs, or squatting), suggesting a knee problem that may need assessment or intervention. Scores at or above 85 generally reflect relatively good function in these activities. The other cutoffs would miss people with real sport-related limitations or aren’t aligned with how this subscale is used clinically.
