Surgery of the Knee: Cartilage Restoration - Osteochondral Allograft, Microfracture, OATS, and ACI
The best treatment for a knee injury or disease Is one of biologic origins that restores the knee to a state near normal. ACL (anterior cruciate ligament) reconstruction, anatomic repair of knee fractures, and meniscal repair are three types of biological surgical repairs that are very successful for injured knees.
Orthopedists as well as patients often find managing a full-thickness, symptomatic chondral lesion of the knee to be problematic.
Injury leading to articular cartilage cell death can best be treated by restoring the surface cells of the joint. The surface cells are the articular cartilage. This is the shiny white surface of which all joints in the body are made.
There are 4 ways to treat damage to this tissue. They are: Autologous Chondrocyte Implantation (ACI), Osteochondral Allograft, Osteoarticular transfer system (OATS), and Microfracture.

A smaller lesion in a younger patient can be handled well using Microfracture surgery. In this surgery, a tool like a pick is utilized to make multiple entries into the knee's marrow beneath the chondral defect. This is called marrow stimulation. It causes repair tissue to be created, filling the chondral defect with fibrous cartilage repair tissue.
The patient will use crutches for about 6 to 8 weeks. He or she must forgo sports for half a year to a year. It may take as much as 18 months for complete relief of pain to be achieved.
It is possible to restore the knee surface to a near-normal condition with a procedure called autologous chondrocyte implantation (ACI). This procedure is used if the knee defect is large.
ACI uses articular cartilage cells that have been harvested from the healthy part of the injured knee. There are strict indications and use criteria in place where cartilage restoration procedures are concerned.
These conditions are: 1. A full-thickness, weight-bearing, symptomatic chondral injury of the femoral articular surface. 2. A physiologically young patient. 3. The patient must understand and agree to participating in an 18 month rehabilitation process.
Surgery to the tibia and patella may not be successful. For this reason, insurance companies often refuse payment for surgery of this type. ACI is not a workable procedure for treating osteoarthritis. This is a condition in which two reciprocal joint surfaces are damaged. X-rays show narrowing of the joint space, as well as bone spurs. The use of a 3T MRI (magnetic resonance imaging) can assess for ACI. This procedure can help determine the proper treatment.
