### KOOS Jr. (Knee injury and Osteoarthritis Outcome Score Junior)

**Description:** The KOOS Jr. is a shortened version of the KOOS, designed to evaluate the symptoms, function, and knee-related quality of life in patients with knee injuries and osteoarthritis. It is intended to be a quicker and easier tool for both patients and clinicians while maintaining the comprehensiveness of the full KOOS.

**Conditions Measured:**

- Knee Injuries
- Knee Osteoarthritis

**Number of Items:** 7 items

**Estimated Time to Complete:** 2-3 minutes

**Scoring Method:** The KOOS Jr. consists of 7 items covering pain, other symptoms, and knee-related function. Each item is scored on a scale from 0 to 4, with the scores transformed to a 0-100 scale, where higher scores indicate better knee function and fewer symptoms.

**Reliability:** The KOOS Jr. has demonstrated high test-retest reliability and internal consistency across different patient populations.

**Validity:** Numerous studies have validated the KOOS Jr., showing strong construct validity, responsiveness, and sensitivity to changes in knee conditions.
