Cartilage or Osteochondral Defects in the Knee
Conditions
Brief summary
Evaluate the performance of the Agili-C™ in the repair of Cartilage and Osteochondral defects.
Detailed description
Agili-C™ implant is a CE marked, bi-phasic, porous resorbable tissue regeneration scaffold for the treatment of articular cartilage and/or osteochondral defects. The Agili-C™ implant will be implanted using the Agili-Kit™ surgical toolset which is designed for the precise preparation of sites in cartilage and osteochondral defects, for implanting the Agili-C™ implant
Interventions
DEVICEAgili-C™ implantation procedure
Candidates for Agili-C™ implantation will be screened for possible inclusion in the trial. Candidates that are approved by the adjudication committee will be considered for study enrollment and then operated. Note: in case intra-operatively a medical condition is observed which is not aligned with the inclusion/exclusion criteria, the Subject will not be implanted with the Agili-C™ device and will not be considered enrolled in the study.
