Post-traumatic arthritis

What is post-traumatic arthritis?

Post-traumatic arthritis is a form of osteoarthritis that develops over time after a joint injury, such as a ligament or cartilage tear, or a bone fracture. This condition can cause pain, swelling, and stiffness in the affected joint, and it often progresses if left untreated.

Penn Medicine offers experienced care in the management of post-traumatic arthritis, with comprehensive treatment options to help you regain mobility and reduce pain.

Symptoms of post-traumatic arthritis

The main symptoms of arthritis from trauma include:

  • Joint pain
  • Swelling
  • Stiffness
  • Difficulty moving the affected joint
  • Cracking or grating sound when the joint moves

These symptoms may not show up right away after an injury. In some cases, it can take months or even years for post-traumatic arthritis to develop.

What causes post-traumatic arthritis?

Post-traumatic arthritis typically develops after injuries that damage the joint surface or change how the joint moves. These injuries are often the result of car accidents, sports injuries, or falls, which can roughen the joint surface and lead to pain and inflammation over time.

Common injuries that may lead to post-traumatic osteoarthritis include:

Not every joint injury leads to post-traumatic arthritis. Severe injuries that damage cartilage or alter joint alignment, injuries in weight-bearing joints like the knees, hips, and ankles, and inadequate treatment or rehabilitation all increase the risk of arthritis. Individual factors such as age, weight, genetics, and overall health can also affect whether arthritis develops after an injury.

Reducing the long-term impact of joint injuries

Accidents happen and can’t always be avoided, but you can help reduce your risk of developing arthritis from trauma or injury by taking steps to lessen the damage, such as:

  • Wearing protective gear during sports
  • Maintaining a healthy weight to lessen joint strain
  • Exercising to strengthen muscles and joints
  • Using the correct form when doing physical activities
  • Seeking prompt treatment for joint injuries
  • Following rehabilitation plans carefully after injury
  • Avoiding high-impact activities after an injury
  • Supporting joint health with good diet and exercise
