What condition is characterized by inflammation of the joints?

The condition characterized by inflammation of the joints is arthritis. This term encompasses a group of more than 100 different types of inflammatory joint diseases. Symptoms commonly associated with arthritis include pain, swelling, stiffness, and decreased range of motion in the affected joints.

Arthritis can result from various factors including wear and tear on the joints (osteoarthritis), autoimmune issues (rheumatoid arthritis), or infections. Understanding the nature of arthritis is crucial for effective management and treatment, which can include medications, physical therapy, and lifestyle modifications to maintain joint function and alleviate symptoms.

The other options relate to different types of physical issues: fractures refer to breaks in bones, cancer involves abnormal cell growth which can affect the joints indirectly, and sprains pertain to ligament injuries rather than inflammation of the joints themselves. Thus, arthritis is clearly the correct response when discussing joint inflammation specifically.
