A type of arthritis that develops in children affecting the knee, but the specific knee (left or right) is not documented or is bilateral.

- •Query the provider if laterality can be determined from imaging or clinical findings
Clinical Significance
Juvenile arthritis of unspecified knee indicates chronic inflammatory joint disease in a weight-bearing joint that can significantly affect ambulation and development in children. This condition requires specialized pediatric rheumatology care and ongoing monitoring to prevent long-term joint damage and functional limitations.
Documentation Requirements
- ✓Patient age at arthritis onset (under 16 years)
- ✓Evidence of chronic arthritis lasting 6 weeks or longer
- ✓Knee joint involvement without laterality specification
- ✓Documentation of inflammatory signs and symptoms
- ✓Exclusion of other arthritis causes (infectious, traumatic)
- ✓Functional impact assessment on mobility
- ✓Current medications and treatment response
- ✓Appropriate imaging and laboratory studies
