About this study
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.
Read the detailed description
Recent developments in the treatment of articular cartilage defects have resulted in several techniques that involve the stimulation of native cellular components for the purpose of differentiation and proliferation in the cartilage defect. Techniques of interest for this study are the use of microfracture combined with platelet rich plasma (PRP), and a recently developed augmentation of the microfracture procedure-BioCartilage.
The microfracture procedure is performed with PowerPick. During the procedure, a patient with focal cartilage defect undergoes arthroscopic debridement of the defect before microfracture is used to create holes in the subchondral plate in order to provide access to mesenchymal stem cells (MSCs). To complete this marrow stimulating procedure (MSP), the microfractured region is filled with PRP harvested intraoperatively from the patient. A fibrin glue is then used to cover the defect and hold the PRP repair in place.
This basic MSP has been shown to regenerate cartilage tissue and improve joint function. Microfracture treatments using PRP are "shown to have good to excellent short-term outcomes in appropriately indicated patients" (Abrams, Mall, Fortier, Roller, \& Cole, 2013), however successful long-term outcomes have not been demonstrated in the literature.
BioCartilage, a novel therapy developed by Arthrex Inc, is implemented as an augmentation of the basic approach of using microfracture and PRP. All aspects of the procedure, as well as indications for the procedure, are the same as the basic MSP described above, except the PRP is combined with BioCartilage powder, which acts as a scaffolding for cellular growth. BioCartilage is an FDA approved augmentation of microfracture treatment with PRP, and the powder itself contains no living cells.
Animal models using BioCartilage have provided data that supports the assertion that the BioCartilage augmentation may improve outcomes for patients who receive it; however there is currently no published human clinical outcomes data available for using BioCartilage (Abrams et al., 2013).

What is being measured
The primary outcome is the main question the study is designed to answer.
MRI Repair Tissue Comparison
The primary endpoint is to determine whether subjects receiving a marrow stimulating procedure (MSP) augmented with BioCartilage have improved outcomes (MRI) compared to subjects who receive MSP without the use of BioCartilage. Quantitative (%fill) and qualitative (tissue quality) MRI assessments of repair tissue will be performed by a musculoskeletal (MSK) radiologist who is blinded to treatment group, and compared for differences between treatment groups.
Measured: 1 year post-operatively
Secondary outcomes (1)
Short Form-12 Health Survey (SF-12)
The 12-item Short Form Survey (SF-12) is a general health questionnaire. The SF-12 was constructed using questions drawn from each of the 8 dimensions of the MOS 36 item Short Form Survey (SF-36). It is designed to have similar performance to the SF-36, while taking less time to complete. Two summary scores are reported from the SF-12 - a mental component score (MCS-12) and a physical component score (PCS-12). Physical and Mental Health Composite Scores (PCS \& MCS) are computed using the scores of twelve questions and range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health.
Measured: Approximately 2 years
