Arthroscopy of The Knee Joint
The knee comprises the joint between the femur and the tibia but also the joint between the patella and the front of the femur. Between the femur and the tibia sit two crescentic cartilages or menisci. . The ligaments around the knee stabilise the knee. They include the collateral ligaments; medial and lateral, lying either side of the knee and the cruciate ligaments, anterior (ACL) and posterior cruciate ligament (PCL), lying within the joint. The fibrous capsule, which surrounds the knee, completes the stability of the joint. The muscles supporting the knee joint are the quadriceps muscle, which is the large bulk of muscle lying at the front of the thigh, and the hamstrings which lie behind the thigh.
Articular cartilage repair
Chondral injures present an unique exceptional challenge to the treating physician in view of the poor natural healing capacity of the articular cartilage cells
Articular cartilage is avascular and therefore has a limited repair capacity. The function of the articular cartilage is to allow lubricated low friction gliding movements of joints and to cushion the loading across the joint. Articular cartilage is made up of dense Type II collagen, a proteoglycan matrix and chondrocytes fixed within the matrix. The fluid contained as hydrostatic pressure within the homeostasis within the extracellular matrix of articular cartilage. This maintains the mechanical integrity of the articular cartilage to withstand the compressive loads across a joint and allow gliding and sliding movement.
