Multicenter Prospective Randomized Study of MaioRegenTM Prime vs. Debridement (Surgical Standard of Care (SSOC)) for the Treatment of Osteochondral Lesion of the Knee Joint - OSTEOCONFIRM Study

The present study aims to compare the efficacy and the safety of MaioRegen Prime to Debridement (SSOC) in patients with deep osteochondral lesions of the knee joint. The foreseen population involves patients with osteochondral lesions with different etiology, dimension, shape, and location.

The evaluation will be performed through clinical, subjective and objective assessments.

Bevonási feltételek: Informed consent prior to any study-related procedures; Male or female patients aged between 18 and 60 years (inclusive); Body Mass Index (BMI) ≤ 35; Up to 3 treatable osteochondral lesions localized in femoral condyles and/or trochlea (the patient might have other lesion in other parts of the joint, but they should not be more severe than ICRS Grade II lesions as determined by baseline MRI); Knee osteochondral lesion(s) (Grade IVa and IVb according to ICRS Classification) or not re-fixable knee Osteochondritis Dissecans lesions as determined by baseline MRI; Lesions with an overall treatable area 1-7 cm2 (as determined by baseline MRI). In case of multiple lesions (maximum 3 lesions) in the same knee compartment a minimum distance of 3 mm is required); IKDC Subjective score at baseline (pre-op evaluation) is less than 70; Non-responsive to physical therapy for at least 6 weeks; Patients physically and mentally willing and able to comply with the post-operative rehabilitation protocol and scheduled clinical and radiographic visits.

Kizáró feltételek: Patients previously treated for total or partial meniscectomy in the specific index knee compartments (more than 50% of the meniscus in the index compartments is missing); Patients affected by any concomitant painful or disabling disease of the spine, hips, or lower limbs, including the contralateral knee, that would interfere with the evaluation of the index knee; Intra-articular steroid injections within 3 months; Any previous cartilage repair procedure (such as: microfracture, Osteochondral autograft transplantation system (OATS), Autologous Matrix Induced Chondrogenesis, (AMIC), Autologous Chondrocyte Implantation (ACI) with or without use of a scaffold (matrix) in the index knee within one year or debridement within 6 months; Patients who underwent chemotherapy in the past 12 months; Participation in other clinical trials within 90 days prior to the study or concurrent with the study; Known drugs or alcohol abuse; Patients with a known history of any significant systemic disease (such as but not limited to: HIV, hepatitis, HTLV, syphilis, coagulopathies, insulin dependent diabetes mellitus etc.) or affected by a significant malignancy; Any evidence of active infection anywhere in the body.
