E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Efficacy: To compare the treatment efficacy of a combination of conventional microfracture and autologous MSC seeded onto the acellular 3D scaffold as compared to the commonly used method of microfracture and application of the scaffold alone, in subjects with knee joint chondral lesion. |
|
E.2.2 | Secondary objectives of the trial |
Safety: To confirm the safety of autologous MCS administration, as has previously been demonstrated in other orthopaedic indications (rotator cuff, revision hip arthroplasty, posterolateral spinal fusion etc.). |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Adult patients of either sex, age between 18 and 55 years. 2. Confirmed diagnosis of chondral defects of the weight bearing compartment of the knee joint up to the radiologically confirmed knee osteoarthrosis stage II (according to Kellgren classification), the cause of the defect being either trauma or incipient degeneration. 3. Defect is located in the weigh-bearing part of femoral condyle. 4. Scheduled to undergo an open surgery of the knee for the chondral defect management (namely microfracture of the subchondral bone followed by the application of a 3D scaffold). 5. Isolated chondral defect with a maximum size of 6 cm2. 6. No previous knee surgery due to a treatment of a chondral defect. 7. Preoperative level of hemoglobin at least 110 g per L. 8. Preoperative level of platelet count higher than 150 000 per mL. 9. Sexually active, nonsterile female patients need to use highly effective contraception during the whole study. 10. Able to provide written informed consent.
|
|
E.4 | Principal exclusion criteria |
1. Axial deformities over 10° on the study knee. 2. Systemic corticosteroid or immunosuppressive medication, or anticoagulant therapy, ongoing or recent, (used regularly during the last 3 months before the planned knee surgery). Intraarticular corticosteroid medication is not allowed within the same time period. 3. Active infection or any other condition limiting the healing (e.g., immunodeficiency, hepatitis, active tuberculosis, neoplasm, diabetes and other serious metabolic disorders, drug abuse, etc.). 4. Concurrent or previous cancer. 5. Blood, plasma or platelet transfusion during previous 8 weeks. 6. Pregnant or lactating women. 7. BMI higher than 40. 8. Clinical instability of the knee joint. |
