Brief Summary:
To evaluate the use of ReNu™ allograft for the augmentation of marrow stimulation for osteochondral lesions

Condition or disease Intervention/treatment Phase
Osteochondral Defect Other: ReNu Not Applicable

Detailed Description:

This is a prospective, non-randomized, longitudinal study of up to 8 evaluable participants recruited from two separate practices. Male and non-pregnant female patients between the ages of 18 and 55 years of age will be screened for study recruitment. Female patients must be actively practicing a contraception method, abstinence, be surgically sterilized, or be postmenopausal. Participants will receive ReNu™ as an adjunct to their standard of care marrow stimulation for the treatment of osteochondral defects.

At each follow-up visit, concomitant medications and adverse events shall be collected from each subject, and each subject shall complete the following questionnaires:

IKDC Health Assessment (Includes Short Form-36) Tegner KOOS Knee Survey VAS Pain Scale SANE score

The subjects will be assessed at Baseline using these scales an again at all subsequent study follow-up visits.

Pretreatment arthroscopic confirmation indicating one or two contained lesion(s) and equal to an ICRS Grade 3a, 3b, 3c, 3d of the femoral condyle, patella, or trochlear groove and OCD lesions (Grade 4a) with healed bone base, which is non-sclerotic and no loss of bone greater then 6mm measured from the surrounding subchondral plate. Original pretreatment arthroscopic confirmation indicates that one or two lesion(s) are equal to an ICRS Grade 3a, 3b, 3c, 3d contained lesion(s) that is equivalent to an Outerbridge Grade III or IV (greater than 50% loss of articular cartilage). OF NOTE: Patients with need for concomitant procedures such as Anteromedialization of Tibial Tubercle (AMZ) and lateral lengthening are allowable
  5. Has peripheral cartilage debridement to healthy cartilage that results in a lesion (s) with an area of > or = 1cm ^2 and < or = 4 cm^2.
  6. PCL, LCL and MCL in the affected knee are stable and the ACL is stable or can be stabilized as a concomitant procedure.
  7. Ipsilateral knee compartment has intact menisci (or requires partial meniscectomy resulting in stable menisci). Minimum remnant width of 5mm.
  8. The contralateral knee is asymptomatic, stable, and fully functional.
  9. Must be physically and mentally willing and able to comply with post-operative rehabilitation and routinely scheduled clinical and radiographic visits through 24 months.
  10. Alignment: Mechanical axis must be no more than 5 degrees from neutral.
  11. Must be 3 months post previous surgery.

Exclusion Criteria:

  1. Clinical and/or radiographic disease diagnosis of the indexed affected joint that Includes:

    1. Osteoarthritis or avascular necrosis,
    2. Rheumatoid arthritis, or history of septic or reactive arthritis,
    3. Gout or history of gout or pseudogout in the affected knee,
    4. Osteochondritis dissecans of the knee with significant bone loss (greater than 6mm deep from the subchondral plate)
    5. Associated damage to the underlying subchondral bone requiring a bone graft
  2. History of secondary arthropathies (i.e. sickle cell disease, hemochromatosis, or autoimmune disease).
  3. Uncontrolled diabetes.
  4. Displays a high surgical risk due to unstable cardiac and/or pulmonary disease.
  5. Has HIV or other immunodeficient state including subjects on immunosuppressant therapies, or has significant illness (metastasis of any type) that decreases the probability of survival to the 2 year endpoint.

  21. Has history of alcoholism, medication, or intravenous drug abuse, psychosis, is a prisoner, has a personality disorder (s), poor motivation, emotional or intellectual issues that would likely make the subject unreliable for the study, or any combination of variables in the investigator's judgment that should exclude a potential subject.
