Arthritis is a form of arthropathy that involves inflammation of one or more joints, while the term arthropathy may be used regardless of whether there is inflammation or not.

Joint diseases can be classified as follows:

• Arthritis

• Septic arthritis (infectious)
• Tuberculosis arthritis
• Reactive arthritis (indirectly)

• Noninfectious arthritis

• Seronegative spondyloarthropathy:

• Psoriatic arthritis
• Ankylosing spondylitis

• Rheumatoid arthritis:

• Felty's syndrome

• Juvenile idiopathic arthritis
• Adult-onset Still's disease
• Crystal arthropathy

• Gout
• Chondrocalcinosis

• Osteoarthritis

• Hemarthrosis (joint bleeding)
• Synovitis is the medical term for inflammation of the synovial membrane.
• Joint dislocation

With arthropathy in the name

• Reactive arthropathy (M02-M03) is caused by an infection, but not a direct infection of the synovial space. (See also Reactive arthritis)
• Enteropathic arthropathy (M07) is caused by colitis and related conditions.
• Crystal arthropathy (also known as crystal arthritis) (M10-M11) involves the deposition of crystals in the joint.
  • In gout, the crystal is uric acid.
  • In pseudogout/chondrocalcinosis/calcium pyrophosphate deposition disease, the crystal is calcium pyrophosphate.
• Diabetic arthropathy (M14.2, E10-E14) is caused by diabetes.
• Neuropathic arthropathy (M14.6) is associated with a loss of sensation.

Spondylarthropathy is any form of arthropathy of the vertebral column.
