Arthritis is a general term covering numerous conditions where the joint surface or cartilage wears out. The joint surface is covered by a smooth articular surface that allows pain-free movement in the joint. This surface can wear out for several reasons; often the definite cause is not known. Arthritis often affects the knee joint.
Knee pain is a common condition affecting individuals from different age groups. It not only affects movement but also impacts the quality of life of the individual. An injury or disease of the knee joint or any structure surrounding the knee can result in knee pain.
A fracture is a condition in which there is a break in the continuity of the bone. In younger individuals, these fractures are caused from high energy injuries, as from a motor vehicle accident. In older people, the most common cause is weak and fragile bone.
Pain, swelling and stiffness are the common symptoms of any damage or injury to the knee. If care is not taken during the initial phases of injury, it may lead to joint damage that may end up destroying your knee.
Injury to more than one knee ligament is called a multiligament knee injury and may occur during sports or other physical activities.
Lateral patellar compression syndrome refers to pain under and around your kneecap. It is a common complaint among runners, jumpers, and other athletes such as skiers, cyclists and soccer players.
Unstable knee can be caused by sudden twisting of the knee, tears of the meniscus, ligament or capsule, osteoarthritis of the knee (wear and tear of the cushioning cartilage tissue between bones) and sports injuries. When these tissues get injured, the patella or kneecap can move out of its groove in the knee joint and lead to instability.
Osteochondritis dissecans is a joint condition in which a piece of cartilage, along with a thin layer of the bone separates from the end of the bone because of inadequate blood supply. The separated fragments are sometimes called "joint mice". These fragments may be localized, or may detach and fall into the joint space causing pain and joint instability.
