Osteoarthritis and post traumatic arthritis
Osteoarthritis is the most common type of arthritis. As we age, the chances of developing arthritis increases, though the severity of the disease is different for everyone. People in early stages of life can also develop osteoarthritis.
Osteoarthritis breaks down the cartilage in joints and can occur in almost any joint in the body, though it occurs most often in the hips, knees and spine. Cartilage is the cushion that covers the ends of bones in normal joints and helps provide protection so those bones don’t rub together. It also serves as a shock absorber as wear and tear occurs in the joints after years of use. The cartilage can also be damaged by injuries or fractures to the joints resulting in post traumatic arthritis.
Risk factors for developing hip osteoarthritis include:
- Being overweight
- Increasing age
- Previous hip fracture or injury
- Family history of osteoarthritis
- Repetitive stress on the joint through work or sport
- Genetic defects in cartilage or improper formation of the hip joint at birth
As rheumatoid arthritis is an autoimmune disease, the exact cause is not known however family history and environmental factors are thought to be risk factors to the disease developing.
