Comparison of BioCartilage Versus Marrow Stimulating Procedure for Cartilage Defects of the Knee

Subjects will be selected among the investigators' patient population who are already scheduled to receive a marrow stimulating procedure (MSP), with or without the addition of BioCartilage. During the surgical operation for MSP, a portion of the patient's blood is taken out and used to form a patch to cover a cartilage defect of the knee. Currently it is considered standard of care to either form the patch using only a portion of the patient's blood, or form the patch using a portion of the patient's blood combined with an FDA-approved augmentation such as BioCartilage. This study will collect outcomes data and MRI for patients that are undergoing MSP with and without BioCartilage augmentation, then compare the data between those who received BioCartilage and those who did not. The primary endpoint is to determine whether subjects receiving a marrow stimulating procedure (MSP) augmented with BioCartilage have improved outcomes (measured using quality of life indicators, functional outcomes, and MRI) compared to subjects who receive MSP without the use of BioCartilage.
