What is osteochondral autograft?
Osteochondral autograft transfer (OATS) involves harvesting bone and intact articular cartilage from a less weight bearing portion of the knee to fill the defect in the weight bearing portion. It can be performed arthroscopically.
How much does an osteochondral allograft cost?
Osteochondral allograft transplantation The downsides of this technique are graft availability, cost (with grafts approaching upward of $10,000), and the risk of disease transmission.
What is a fresh osteochondral allograft?
Fresh osteochondral allograft (OCA) transplantation involves the transfer of size-matched allograft cartilage and subchondral bone into chondral or osteochondral defects of the knee.
What is an autograft allograft?
A patient’s own tissue – an autograft – can often be used for a surgical reconstruction procedure. Allograft tissue, taken from another person, takes longer to incorporate into the recpient’s body .
What is osteochondral allograft transplantation?
Osteochondral grafting is a method of treating cartilage injuries that expose underlying bone. An osteochondral allograft is a piece of tissue containing bone and cartilage that is taken from a deceased donor to replace damaged cartilage that lines the ends of bones in a joint.
What does osteochondral mean?
Medical Definition of osteochondral : relating to or composed of bone and cartilage.
Why is autograft better than allograft?
Which is better? Both of these are often successful options for a graft delivery procedure. While autografts have a higher success rate, allografts result in a quicker recovery time. Depending on the injury, your doctor will be able to make the right call for the type of graft to use.
What causes osteochondral?
Osteochondral lesions are usually caused by an injury, such as an ankle sprain, which damages the cartilage and forces it to soften and slowly break off. A broken piece of cartilage may remain in the ankle, causing an osteochondral lesion to occur.
What is the difference between autograft and osteochondral allograft transplant?
Policy context. Osteochondral Allograft Transplant Surgery is a graft procedure similar to Osteochondral Autograft Transfer System, but using graft material from preserved cadaver cartilage. There is some indication that allograft cartilage does not integrate as well, and transplantation involves some risk of infection.
Where does the bone come from for an osteochondral graft?
Osteochondral grafts replace both the articular cartilage on the surface and the underlying bone. The tissue can come from other parts of the patient’s body (called osteochondral autograft) or from a tissue donor (osteochondral allograft). These techniques are commonly used in the knee but can be used in other joints.
Is it safe to transplant allograft cartilage into a knee?
There is some indication that allograft cartilage does not integrate as well, and transplantation involves some risk of infection. However, adequate healthy cartilage tissue is not always available within the joint under repair.
How long does it take to recover from autograft and allograft?
Activity is gradually increased with return to sport typically occurring after 6-9 months. Patients often recover from both of these procedures. One advantage of these techniques is the ability to replace both cartilage and bone with similar tissue.
