1. Osteoarthritis. The most common type, osteoarthritis is the "wear-and-tear" form that increases with age. Cartilage that normally cushions the joint breaks down over time, leading to stiffness and pain, especially with movement. With hip arthritis and knee arthritis, walking becomes more difficult as pain builds, and flexibility decreases. Adults in their 50s and older are more likely to develop this chronic, progressive disease, and women are more vulnerable. Surgical replacement of large joints, such as hip replacement or knee replacement, is needed in some cases.

2. Metabolic bone diseases. Osteoporosis is one of several metabolic bone diseases. These are disorders of bone strength caused by mineral or vitamin deficiencies (such as vitamin D, calcium, or phosphorus) that result in abnormal bone mass or structure. Osteomalacia (softening of the bones), hyperparathyroidism (overactive gland leading to bone calcium loss), Paget disease of bone (abnormally large, weakened bones), and developmental bone disorders affecting children are all different types of metabolic bone diseases.

3. tress fractures are more common in active people like runners.

Explanation:

For rheumatoid arthritis, medications to slow the disease process include older drugs like methotrexate (Trexall and others) and sulfasalazine (Azulfidine). Biologic drugs such as adalimumab (Humira) and etanercept (Enbrel) reduce inflammation by targeting the immune system. Low-dose steroids are sometime used for short-term treatment.
