This is a single arm, open label multi-center study to determine safety and the performance of the treatment of cartilage lesions located on the femoral condyle with GelrinC.

Patients meeting inclusion/exclusion criteria at screening will be enrolled into the study, and will receive treatment implantation into their cartilage lesions.

Treatment will consist of GelrinC implantations at the symptomatic lesion of femur rated as ICRS III, or IVA with less than 6 mm of bone loss below the subchondral plate.

The patients will undergo a rehabilitation program during the follow up period.

Phase 1
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase I/II Study for the Safety and Performance of GELRIN C

  4. ICRS Grade larger than grade II on a surface that directly opposes the defect
  5. Osteoarthritis or avascular necrosis (clinical and/or radiographic diagnosis)
  6. History of autoimmune disease or inflammatory arthropathy, such as rheumatoid arthritis, systemic lupus, active gout, septic or reactive arthritis including any history of a positive ANA blood test.
  7. History of chronic debilitating systemic disease and any other unstable cardiac and pulmonary disorders.
  8. History of current or prior malignancy within the last 5 years.
  9. Patients treated in the affected knee with microfracture in the last 12m months or had prior tendon repair, meniscus repair, ligament repair or realignment surgery in the last 6 months.
  10. Patient with prior total or subtotal meniscectomy.
