Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- Proportion of patients with a serious adverse event within 24 months after surgery
Secondary endpoints 7
- Regeneration of damaged cartilage measured by MOCART score (relative change in the value 12 months after surgery compared to the initial value before surgery)
- Relative change in knee joint pain 12 and 24 months after the surgery compared to the baseline value before the surgery measured using the KOOS Pain Subscore
- Relative change in knee-related quality of life 12 and 24 months after surgery compared to baseline before surgery measured by KOOS-QoL subscore
- Relative change in symptoms and stiffness 12 and 24 months after surgery compared to pre-surgery baseline as measured by KOOS symptom subscore
- Relative change in activities of daily life 12 and 24 months after surgery compared to baseline before surgery measured by KOOS-ADL subscore
- Relative change in physical resilience during sporting activities 12 and 24 months after the surgery compared to the baseline value before the surgery measured by KOOS-Excercise /Rec-Subscore
- AE, AR, SAE, SAR, SUSAR: Description of all adverse events (AE, AR, SAE, SAR, SUSAR) within 24 months after surgery in terms of severity (assessed according to National Cancer Institute - Common Terminology Criteria for Adverse Events Version 5.0 (NCI-CTCAE V 5.0)), causality, outcome
