Arthritis is the inflammation of one or more of your joints. There are three different types of arthritis that can occur in your knees. These include rheumatoid, post-traumatic, and osteoarthritis.

Rheumatoid Arthritis is an autoimmune disease in which the body’s immune system attacks the joints and other parts of the body.

Post-traumatic Arthritis can develop after an injury, like a fracture, torn ligament, or a torn meniscus.

Osteoarthritis is a progressive disease that slowly wears away the cartilage in the body’s joints. It is the most common form of arthritis.

Arthritis of the knee may be painful and cause inflammation.


Although it can appear suddenly, the symptoms will typically develop slowly over time. The following symptoms may occur:

  • The joint may become stiff and swollen, making it difficult to bend the knee.
  • Pain and swelling may be worse in the morning, or after a period of rest.
  • Vigorous activity may cause pain to flare up.
  • The knee may “lock” or “stick” due to interference from loose cartilage.
  • The knee may creak, click, snap or make a grinding noise.
  • Pain may cause a feeling of weakness or buckling in the knee.
  • Joint pain may increase with rainy weather.

While there is no cure for arthritis, there are a number of treatments to help ease the pain and reduce the chances of it becoming worse.

Initially, arthritis of the knee is treated conservatively. Nonsurgical treatment of arthritis may include one or several of the following:

  • Applying heat, ice, or pain-relieving ointments
  • Medications, such as anti-inflammatory drugs and pain relievers
  • Corticosteroid injections
  • Orthotics to help stabilize the knee cap
  • Physical therapy and exercise
  • Acupuncture, magnetic pulse therapy, and other alternative therapies

If conservative treatment fails to relieve the symptoms of arthritis, arthroscopic or knee replacement surgery will likely be recommended. Recovery and rehabilitation from these surgeries may last for several months.

Alternatively, some patients may benefit from regenerative therapy in order to significantly minimize recovery and rehabilitation time.
