Common torn cartilage injuries include the labrum tear of the shoulder which include slap tears, bankart tears and posterior labral tears. The torn cartilage is also seen in triangular cartilage or as it is also known the triangular fibrocartilage. This cartilage is situated near the little finger along the wrist. This is stabilizer cartilage hence its injury can cause significant immobility of the hand and causes problems in forming a sturdy grip. These injuries are most often seen with weightlifter who support a lot of weight along there wrist and in certain situation may tear it. Another form of a tear injury to a cartilaginous area is a tear to the rib cartilage. These generally happen in impact injuries and during road traffic accidents. impact injuries of the knee may also cause a tear in its cartilage. The cartilage in the knee is known as the meniscus and is a fibrocartilage shaped in the form of the alphabet C. it is situated in the posterior part of the popliteal fossa and provides nutrition as well as lubrication to the knee joint. The knee in itself has two menisci, these are the medial and lateral and they function as cushions or spacers between the tibia and the femur respectively. The meniscus in itself has no vascularization, hence in case of an injury the autoimmune system does not kick in to heal that injury. Meniscal injuries are most often related to trauma, and in cases of a torn meniscus the cartilaginous structure begins to move within the knee joint itself. Other cartilage injuries include the torn Knee cartilage or meniscal and ligament injuries are an epidemic in modern sport. These injuries usually occur when a very high twisting force is applied to a bent knee. If contact sports would not allow the use of studs on boots the injury would probably almost totally disappear. The other common cause for an acute haemarthrosis following an acute intrinsic injury to the knee is the dislocation of the patella. Almost all cartilage injuries cause significant pain, swelling and marked immobility.
The treatment for almost all these cartilaginous injuries requires complete immobility and in most cases surgery. Treatment in case of a meniscal tear include either repair, or transplantation or even the complete removal of the meniscus its self. Meniscus replacement therapy is used in patients who have already undergone a meniscectomy and are young as well as have minimal arthritic degeneration of the knee. Pre procedural preparations include x rays which need to be done to rule out any sort of anatomical and degenerative pathologies. The radiograph is also very important in determining the size of the allo graft that would be required, and with this information the eventual process of finding a suitable donor for the meniscus is begun. Treatment incase of labral injuries depend basically on the location of the torn cartilage itself. Most of these injuries do not require surgical intervention, but in patients who exhibit chronic symptoms besides undergoing physiotherapy and medical treatment may require an eventual surgical intervention to correct the tear.
