Prospective Evaluation of ProChondrix CR for Repair of Articular Cartilage Defects on Femoral Condyle and Patella

Running, not enrolling

Conditions studied: Cartilage Injury, Cartilage Damage

In brief

The purpose of this clinical study is to evaluate the use of ProChondrix Cryopreserved Osteochondral Allograft to obtain evidence of effectiveness, defined as an improvement in physical function and pain, when used on a symptomatic cartilage defect on the femoral condyle or patella in a mechanically stable knee.

• Active malignancy: undergoing treatment for tumor or boney traumatic injury or a history of any invasive malignancy (except non-melanoma skin cancer), unless the patient has been treated with curative intent and there have been no clinical signs or symptoms of the malignancy for at least 5 years;
• Clinical and/or radiographic disease in the affected joint that includes: osteoarthritis or avascular necrosis, gout or a history of gout or pseudogout, osteochondritis dissecans with significant bone loss;

• Received hyaluronic acid injections into the joint space ≤ 90 days prior to surgery;
• Is a female patient who is pregnant;
• Physically or mentally compromised (i.e. being currently treated for a psychiatric disorder, senile dementia, Alzheimer's disease) in a manner that would compromise his/her ability to participate in the clinical study;
• Has a history of substance abuse (recreational drugs, alcohol) or has been treated in the last 6 months before enrollment for alcohol and/or drug abuse in an in-patient substance abuse program;
