Experimental: Cartilage repair surgery
Single-stage cartilage repair surgery using autologous chondrons (10-20%) and allogeneic MSCs (80-90%) in a fibrin glue carrier with a dosage of two million cells/ cm2 applied once during a surgical procedure.
Other: Cartilage repair surgery
Single-stage surgery, After debridement, the cartilage defect is filled with the fibrin glue carrier containing autologous chondrons and allogeneic MSCs
- Safety: Adverse Events [ Time Frame: 18 months ]Adverse events rate
- Clinical Improvement, Knee Injury and Osteoarthritis Outcome Score [ Time Frame: 3 and 18 months ]Clinical improvement as measured by patient reported outcome scores. The questionnaire has been developed to evaluate the symptoms and limitations for patients with osteoarthritis. The outcome of the KOOS-scale varies from 0-100, where 0 indicates the greatest possible problems and is the worst outcome and 100 indicates no problems.
- Structural Repair [ Time Frame: 12 months ]To examine parameters of structural repair at one year after treatment using MRI and a second-look arthroscopy.
- Health Care Use and Costs [ Time Frame: 18 months ]To assess the healthcare use and costs related to the procedure as well as the health-related work leave during the study period.
