Brief Summary

The Kensey Nash Corp. Cartilage Repair Device is a bioresorbable scaffold designed to promote repair of knee cartilage and subchondral bone. Subjects with knee cartilage damage meeting eligibility criteria will be randomly assigned to receive treatment with the Cartilage Repair Device or a standard surgical technique called microfracture. The purpose of the study is to evaluate the initial safety and effectiveness of the Cartilage Repair Device compared to microfracture.

Study Arms (2)

Treatment

EXPERIMENTAL

Patients assigned to the treatment arm will receive treatment with the Kensey Nash Corp. Cartilage Repair Device.

Device: Kensey Nash Corp. Cartilage Repair Device

Control

ACTIVE COMPARATOR

Patients assigned to the Control Arm will receive treatment with the standard surgical technique known as microfracture.

Procedure: Microfracture

Interventions

To perform the Cartilage Repair Device implantation procedure, the surgeon first removes the damaged cartilage. Then, the surgeon creates a cylindrical hole in the bone below the area of damaged cartilage. The Cartilage Repair Device is then implanted into the hole so that the surface is level with the surrounding native cartilage. The Cartilage Repair Device will then absorb blood and bone marrow from the bone to begin the healing process.

Treatment
MicrofracturePROCEDURE

To perform the microfracture technique, the surgeon will first remove the damaged cartilage. Then, the surgeon will make a number of small fractures in the bone below the area of damaged cartilage. The fractures cause the bone to bleed and a clot to form over the exposed bone. Over time, the clot forms a layer of fibrocartilage over the bone.
