Arthritis is an inflammation of a joint involving the bones, the articular cartilages, ligaments and joint capsules. In an infected or irritated joint the amount of fluid increases and produces swelling. Bacteria may enter the joint through a wound of the joint capsule resulting in damage to the bones and cartilages. The joint may then become immovable. To treat this condition the affected joint is rested.
Medication is used to counteract the inflammation.
If the arthritis is severe, immobilization and resting of the joint is continued for 4 to 6 weeks. The outcome is usual favorable if bone damage or new bone growth has not occurred. An injury to a ligament is defined as a sprain. If an abnormal stress or movement is placed upon a joint such as overextension of a joint, the ligament may be torn. The amount of injury depends upon how much force is placed upon the ligament.
