Arthrosis is a degenerative joint disease that often comes with age. Its name is derived from the Greek word “arthron”, meaning joint. 

Arthrosis is caused by wear and tear of the joints. The cartilage at the bone ends in the joints begins to break down. This mostly starts in a single joint and often affects the knees, hips, and hands.   

Arthrosis is also called Osteoarthritis or “wear and tear” arthritis. It is the most common form of arthritis.

Arthritis is an inflammatory joint disease. This is also shown by the suffix "- itis" which signifies inflammation. However, chronic inflammation and wear often occur at the same time. 

There are many different types of arthritis. Osteoarthritis and rheumatoid arthritis are two of the most common forms. Both have similar symptoms such as pain and swelling. However, the reason behind these symptoms is different.

Osteoarthritis is a degenerative disease caused by joint overuse or injury and age. 

Rheumatoid arthritis (RA) is an autoimmune disease. The body’s own immune system malfunctions and attacks the joints by means of inflammation. It often occurs in the small joints of the hand, wrist, or fingers and affects the same joints on both sides. 

Gout is another common form of arthritis that often affects the joint in the big toe. A build-up of uric acid crystals in the joint leads to inflammation. This causes sudden and intense pain attacks that often happen at night. A blood test can measure if the level of uric acid is higher than normal. 

Fibromyalgia is a condition that does not cause joint pain but muscle pain. Scientists believe that the reason is found in overactive nerves that amplify painful sensations. Due to the similar names, it is sometimes confused with polymyalgia.

Polymyalgia rheumatica or simply polymyalgia is a form of arthritis that causes muscle pain and stiffness. It is thought to be an autoimmune disease and mainly occurs in people over the age of 50.     

A thorough physical examination is important to clarify what kind of rheumatic disease is involved. Then, the most effective treatment can be offered to the patient.
