Details and patient eligibility

About

Multi-center, prospective, concurrently controlled, non-randomized, double-blind (patient and assessor). Treatment of large chondral lesions in the knee with microfracture plus the Chondro-Gide® ACC is non-inferior to treatment of small chondral lesions treated with microfracture alone.

Full description

The study evaluates the investigational treatment for treating large chondral lesions of the knee to the control treatment of microfracture alone for treating small lesions.Eligible patients with a large lesion will be treated with microfracture plus the Chondro-Gide® ACC and compared to patients with small lesions that are treated with microfracture alone. Outcome measures to be assessed include patient reported outcomes and freedom from certain adverse events.
