• Arthritis

:*Infectious 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

• 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.{{cn|date=May 2025}}

Joint pain is a common but non-specific sign of joint disease. Signs will depend on the specific disease, and may even then vary. Common signs may include:{{cn|date=June 2022}}

• Decreased range of motion
• Stiffness
• Effusion
• Pneumarthrosis, air in a joint (which is also a common normal finding).
• Bone erosion
• Systemic signs of arthritis such as fatigue

Diagnosis may be a combination of medical history, physical examination, blood tests and medical imaging (generally X-ray initially).{{cn|date=June 2022}}
