Damaged Cartilage/Ligaments

Articular or hyaline cartilage is the tissue lining the surface of the two bones in the knee joint.  Cartilage helps the bones move smoothly against each other and can withstand the weight of the body during activities such as running and jumping. Articular cartilage does not have a direct blood supply to it so has little capacity to repair itself.

Shoulder ligament injuries are injuries to the tough elastic tissues present around the shoulder that connect bones to each other and stabilize the joint. The ligaments present in the shoulder are connected to the ends of the scapula, humerus, and clavicle bones which form the shoulder complex. The extensive stretching or tearing of these ligaments from acute or chronic injuries can lead to instability in the shoulder joint.

Knee problems may arise if any of these structures get injured by overuse or suddenly during sports activities. Pain, swelling, and stiffness are the common symptoms of any damage or injury to the knee.
