Ankylosing spondylitis is a type of arthritis that causes chronic inflammation of the spine. The tendency to develop ankylosing spondylitis is genetically inherited. Treatment incorporates medications, physical therapy, and exercise.
Aseptic necrosis (avascular necrosis or osteonecrosis) develops when blood supply diminishes to an area of bone and causes bone death. Though aseptic necrosis may be painless, pain is often associated when using the degenerating bone. If caught early, aseptic necrosis may be treated by grafting new bone into the degenerating area. In later stages, joint replacement surgery may be required.
Acute injuries, medical conditions, and chronic use conditions are causes of knee pain. Symptoms and signs that accompany knee pain include redness, swelling, difficulty walking, and locking of the knee.

Rheumatoid Arthritis (RA)
Rheumatoid arthritis (RA) is an autoimmune disease that causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease. The 16 characteristic early RA signs and symptoms include the following. Anemia Both sides of the body affected (symmetric) Depression Fatigue Fever Joint deformity Joint pain Joint redness Joint stiffness Joint swelling Joint tenderness Joint warmth Limping Loss of joint function Loss of joint range of motion Many joints affected (polyarthritis)
A Baker's cyst, also called a popliteal cyst, is swelling caused by knee joint fluid protruding to the back of the knee (popliteal area of the knee). Not uncommon, Baker's cysts can be caused by virtually any type of joint swelling (arthritis). They are often resolved with removal of excess knee fluid in conjunction with cortisone injections.
Arthritis (Joint Inflammation)
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, and pseudogout.
Blood Clots (In the Leg)
Blood clots can occur in the venous and arterial vascular system. Blood clots can form in the heart, legs, arteries, veins, bladder, urinary tract and uterus. Risk factors for causes of blood clots include high blood pressure and cholesterol, diabetes, smoking, and family history. Symptoms of a blood clot depend on the location of the clot. Some blood clots are a medical emergency. Blood clots are treated depending upon the cause of the clot. Blood clots can be prevented by lowering the risk factors for developing blood clots.
Malignant hyperthermia is a severe reaction to certain drugs that are often used during invasive procedures or surgery. Certain mutations in genes increase the risk of a person having malignant hyperthermia. Without prompt treatment, the complications of malignant hyperthermia can be life-threatening.
