Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Lysholm score | Screening up to 52 weeks | It consists of items that measure: pain, instability, locking, swelling, limp, stair climbing, squatting, and need for support. Lowest and highest scores are 0 and 100 (better), respectively. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Arthroscopic assessment of the meniscus | Meniscus repair up to 52 weeks | The structure and function of the repaired meniscus will be assessed in terms of the presence, stability, and smoothness of the meniscus by arthroscopic imaging and MRI. |
| Knee injury and osteoarthritis outcome score (KOOS) | Screening up to the Day before injection,4,12,24 and 52 weeks | The KOOS consists of five subscales; Pain, other symptoms, function in daily living (ADL), function in sport and recreation (Sport/Rec) and knee related quality of life (QOL). Lowest and highest scores are 0 and 100 (better), respectively. |
| Numerical Rating Scale (NRS) | Screening up to the Day before injection,4,12,24 and 52 weeks | NRS consists of an 11-point scale to evaluate current knee pain where no pain is indicated by '0', and the worst pain imaginable by '10'. |
| Kellgren Lawrence | Screening up to 24 and 52 weeks | The Kellgren and Lawrence system is a common method of classifying the severity of osteoarthritis (OA) using five grades. |
