E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the safety of a single dose of autologous MSC seeded on a commercially available acelullar 3D scaffold and fixed by using autologous blood plasma in the repair of knee chondral lesions. |
|
E.2.2 | Secondary objectives of the trial |
To collect preliminary efficacy data from patient administered questionnaires (VAS, KOOS and Lysholm-Tegner scoring scale) and X-ray. To evaluate feasibility of the treatment in current clinical praxis. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1.Adult patients of either sex, age between 18 and 60 years. 2.Confirmed diagnosis of chondral defects of the weight bearing compartment of the knee joint up to the radiologically confirmed knee osteoarthrosis stage III, the cause of the defect being either trauma or progressive degeneration. 3.Scheduled to undergo an open surgery of the knee for the chondral defect management (namely microfracture followed by the application of the 3D scaffold chondrotissue®). 4.No previous knee surgery due to a chondral defect. 5.Preoperative level of haemoglobin at least 110 g per L. 6.Preoperative level of platelet count higher than 150 000 per mL. 7.Able to provide written informed consent.
|
|
E.4 | Principal exclusion criteria |
1.Ligament laxity or 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 screening visit). 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, 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.Subject not using two reliable methods method of birth control. 8.BMI higher than 40. 9.Clinical instability of the joint objectified during the surgery. |
