The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a knee-specific instrument, developed to assess the patients’ opinion about their knee and associated problems. The KOOS evaluates both short-term and long-term consequences of knee injury. It scores the following:
- Pain
- Symptoms
- ADL Function
- Sport and Recreation Function
- Quality of Life
The KOOS proved reliable, responsive to surgery and physical therapy, the KOOS meets basic criteria of outcome measures and can be used to evaluate the course of knee injury and treatment outcomes.
KOOS is intended to be used for:
- knee injury that can result in post traumatic osteoarthritis (OA)
- ACL (anterior cruciate ligament) injury
- Meniscus injury
- Chondral injury
- Ankle and foot problems (FAOS)
- Hip problem (HOOS)
- Rheumatoid arthritis and other inflammatory joint diseases (RAOS)
Advantages of the KOOS
- Inclusion of two different subscales of physical function relating to daily life, and sport and recreation. This enhances the validity for patients with a wide range of current and expected physical activity levels.
- Short- and long-term time intervals
- Assess changes from week to week induced by treatment (medication, operation, physical therapy) or over years following a primary injury or OA.
- Used in research to assess groups and to monitor individuals.
