Arthritis In Knee

arthritis in knee

Arthritis in knee comes in two major forms: osteoarthritis and rheumatoid arthritis. Osteoarthritis is the most common, and it is a degenerative disease that affects the cartilage. Rheumatoid arthritis, which also affects the cartilage, is characterized by swollen, inflamed joints. It is important to note, however, that overlap between the two does exist.

Osteoarthritis

  • Pain and stiffness worsens with use (symptons worse later in the day)
  • Older age of onset
  • Inflammation and swelling is minor
  • Often non-symmetrical

Rheumatoid Arthritis

  • Pain and stiffness often better with use (symptoms worse beginning of the day)
  • Younger age of onset
  • Inflammation and swelling is apparent
  • Often symmetrical

Arthritis in Knee Treatment

Some of the treatments for knee arthritis include; lifestyle modifications such as losing weight, changing your sport from high-impact sports like running to cycling and swimming, exercise, braces and other supportive devices, anti-inflammatory medications, glucosamine and chondroitin sulfate (which help alleviate osteoarthritic pain), among other medications.

Severe Arthritis

For severe arthritis that does not respond to the above therapies, surgery may be indicated. At this point, the knee cartilage is often very worn and damaged. According to our doctors, surgical treatments differ depending on each case.
Options include:

  • Arthroscopic surgery which repairs torn cartilage and cleans up the joint.
  • Knee arthroplasty – after the joint is cleaned, metal and plastic parts are used to partially or completely rebuild the knee.
  • Osteotomy – a bone or bones in the leg are trimmed to improve alignment of the knee.
  • Cartilage graft – a relatively new procedure, it involves replacing the damaged cartilage with new cartilage.

A consultation with an orthopedic doctor is the fastest and safest way to diagnose knee arthritis. If you feel you are suffering from Arthritis, request an appointment today.
