Paste grafting is a relatively simple surgical procedure that can be performed in an outpatient setting. It requires minimal special instrumentation. Unexpected lesions can be treated. No tissue culture or foreign matrices are required. Paste grafting has been an effective salvage procedure for failed microfracture, failed Osteochondral Autograph Transplant Surgery (OATS) or Mosaicplasty procedures, Carticel and TruFit procedures. Compared to the cost of other complex cartilage restoration procedures, the cost of paste grafting is minimal. Disadvantages include limited experience with patella paste grafting and it remains difficult to access the very far posterior lesions.[citation needed]
