What causes post-traumatic arthritis?
Post-traumatic arthritis is caused by the wearing out of a joint that has had any kind of physical injury. The injury could be from sports, a vehicle accident, a fall, a military injury, or any other source of physical trauma. Such injuries can damage the cartilage and/or the bone, changing the mechanics of the joint and making it wear out more quickly. The wearing-out process is accelerated by continued injury and excess body weight.

The symptoms of post-traumatic arthritis include:
- Joint pain
- Fluid accumulation in the joint
- Decreased tolerance for walking, sports, stairs, and other activities that stress the joint.
