Osteoarthritis occurs when inflammation and injury to a joint cause a breaking down of cartilage tissue. In turn, that breakdown causes pain, swelling, and deformity. Cartilage is a firm, rubbery material that covers the ends of bones in normal joints. It is primarily made up of water and proteins. The primary function of cartilage is to reduce friction in the joints and serve as a "shock absorber." The shock-absorbing quality of normal cartilage comes from its ability to change shape when compressed. It can do this because of its high water content. Although cartilage may undergo some repair when damaged, the body does not grow new cartilage after it is injured.
Creaky, achy joints. A twinge in the knee. A sharp shooting pain from the shoulder to the elbow. No big deal, right?
Wrong. All too often, we assume joint pain is a normal part of aging that we just have to learn to live with. Nothing could be further from the truth, say experts, pointing to a wealth of treatment options from exercise and alternative supplements to medications and joint replacement surgery.
It's a serious problem, because pain can affect every aspect of your life. "Pain is not...
Primary: More generalized osteoarthritis that affects the fingers, thumbs, spine, hips, and knees
Secondary: Osteoarthritis that occurs after injury or inflammation in a joint, or as a result of another condition that may affect the composition of the cartilage, such as hemochromatosis
How Does Osteoarthritis Affect the Hip Joint?
Patients who have osteoarthritis of the hip sometimes have problems walking. Diagnosis can be difficult at first. That's because pain can appear in different locations, including the groin, thigh, buttocks, or knee. The pain can be stabbing and sharp or it can be a dull ache, and the hip is often stiff.
What Causes Osteoarthritis of the Hip Joint?
The causes of osteoarthritis of the hip are not known. Factors that may contribute include joint injury, increasing age, and being overweight.
In addition, osteoarthritis can sometimes be caused by other factors:
The joints may not have formed properly.
There may be genetic (inherited) defects in the cartilage.
The person may be putting extra stress on his or her joints, either by being overweight or through activities that involve the hip.
