Osteochondral Allograft, Microfracture, OATS, and ACI Surgery of the Knee: Cartilage Restoration
Biologic treatments are best for knee disease or injury. Biologic treatment restores the knee to a near-normal state. Meniscal repair, reconstruction of the ACL (anterior cruciate ligament), and anatomic knee fracture repair are 3 of the types of biological surgical repairs that work well for knee injuries.
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.
This kind of tissue damage can be treated in four ways: Osteochondral Allograft, Autologous Chondrocyte Implantation (ACI), Osteoarticular transfer system (OATS), and Microfracture.

If the patient is young, a small lesion can be repaired with Microfracture surgery. When using this method, a pick-like tool will be used to enter the marrow of the knee multiple times under the chondral defect. These entries will stimulate the bone marrow. This causes repair tissue to be created. The repair tissue fills the chondral defect with fibrous cartilage 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.
The knee surface may be restored to a near-normal condition using a procedure called autologous chondrocyte implantation (ACI). If the knee defect is large, this procedure is used.
Articular cartilage cells harvested from the healthy part of the injured knee are used in ACI. This surgery may be used under very specific conditions.
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.
