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 that leads to articular cartilage cell death is well treated by restoration of the surface cells of the joint. The shiny white surface that composes all the joints in the body is the articular cartilage or surface cell layer of the joint.
This kind of tissue damage can be treated in four ways: Osteochondral Allograft, Autologous Chondrocyte Implantation (ACI), Osteoarticular transfer system (OATS), and Microfracture.

In a young patient, a small lesion can be treated with Microfracture surgery. In this method, a pick-like tool is used to enter the marrow of the knee under the chondral defect. Multiple entries stimulate the bone marrow, which, in turn creates repair tissue. This tissue fills the chondral defect with fibrous cartilage tissue.
In this situation, the patient will use crutches for four to eight weeks. The patient must agree not to participate in sports for 6 to 12 months. Also, the patient must understand and accept that it may be eighteen months before complete freedom of pain can be expected.
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.
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.
The patient must have a full-thickness, weight-bearing, symptomatic chondral injury to the femoral articular surface. Additionally, the patient must be physiologically young. Furthermore, the patient must agree to an 18 month rehabilitation process.
ACI surgery on the patella and tibia is not always successful. Additionally, insurance companies often refuse to pay for this procedure. ACI is not considered a viable treatment for osteoarthritis. This is a condition in which two reciprocal joint surfaces have been damaged and x-rays reveal a narrowing of the joint space along with the formation of bone spurs. Knees may be assessed for ACI using a 3T MRI (magnetic resonance imaging). In this way, it can be determined whether or not ACI is the correct treatment.
