Articular cartilage is a connective tissue overlying the ends of bones that provides smooth joint surfaces. Healthy cartilage is essential to the proper functioning of joints within the body. Cartilage is composed of cells embedded in an extracellular matrix of collagen fibers and proteoglycans.
Autotransplantation is the transplantation of organs, tissues, or even particular proteins from one part of the body to another in the same person (auto-meaning "self" in Greek [1]). The autologous tissue (also called autogenous, autogeneic, or autogenic tissue) transplanted by such a procedure is called an autograft or autotransplant. [2]
Autograft: graft taken from one part of the body of an individual and transplanted onto another site in the same individual, e.g., skin graft. Isograft: graft taken from one individual and placed on another individual of the same genetic constitution, e.g., grafts between identical twins.
It is used primarily in the evaluation of menisci, cruciate ligaments, articular cartilage, and loose body within a joint. Fluoroscopic allows general view of the medial, lateral, and patellofemoral ligaments of the joint, overall cartilage thickness, focal defects, imbibition (absorption} of contrast material into the articular cartilage (a sign of cartilage fibrillation - splaying and ...
Articular cartilage, most notably that which is found in the knee joint, is generally characterized by very low friction, high wear resistance, and poor regenerative qualities. It is responsible for much of the compressive resistance and load bearing qualities of the knee joint and, without it, walking is painful to impossible.
Autologous articular cartilage transfer from a non-weight-bearing area to the damaged area, called osteochondral autograft transfer system, is one possible procedure that is being studied. [140] When the missing cartilage is a focal defect, autologous chondrocyte implantation is also an option. [141]
An autograft reduces the risk of rejection but requires a second surgery site, adding pain, risk and possible longer aftercare. Xenograft, a transplant from another species; Isograft, a transplant from a genetically identical donor, such as an identical twin. Synthetic and metal implants. Unlike allografts, such grafts do not corporate into the ...
The camera sends video to a large monitor so the surgeon can see any damage to the ligaments. In the event of an autograft, the surgeon makes a larger cut to get the needed tissue. In the event of an allograft, in which material is donated, this is not necessary, since no tissue is taken directly from the patient's own body. [12]
