Clinical Trial Summary

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.


Description:

This clinical study will use a multi-center, prospective design, to evaluate ProChondrix CR in approximately 80 patients who are scheduled to undergo treatment of a cartilage defect on the femoral condyle or patella.Patient follow-up will include a period of 60 months after surgery. During this follow-up period, each patient will be evaluated seven (7) times at: 3, 6, 12, 24, 36, 48 and 60 months after surgical intervention.
