Intra Articular Joint Program At NOI

Arthritis is the most common cause of chronic knee pain and disability. Degenerative, or Osteoarthritis (OA) is one of the most common forms of this disease. OA usually occurs after age 50 and often in an individual with a family history of arthritis. The cartilage that cushions the bones of the knee softens and wears away. The bones then rub together, causing knee pain and stiffness.

Other symptoms of osteoarthritis may include:

  • Aches and pains, typically worse with weight-bearing activities (walking, running)
  • Stiffness that can be worse in the morning
  • Grinding or catching sensations from the knee when standing up or climbing stairs
  • Limited range of motion
  • Swelling

When you have osteoarthritis of the knee:

  • The joint fluid may lose its ability to provide lubrication to protect the joint
  • Smooth cartilage that normally cushions the ends of the knee bones can become frayed and may even wear away completely

The Intra Articular Joint Program [IAJP] at Newport Orthopedic Institute is designed to help alleviate knee pain.


1. Viscosupplementation with hyaluronate
2. Real-time ultrasound guidance

At NOI, our Intra Articular Joint Program (IAJP) includes the use of viscosupplementation performed under real-time ultrasound guidance.


Viscosupplementation is the process of injecting sodium hyaluronate directly into the affected knee joint(s). Hyaluronic acid, or hyaluronate, is a natural component of synovial fluid that can aid in lubricating joints and provide cushioning. It has been proven to reduce the pain, swelling, and inflammation associated with osteoarthritis. While osteoarthritis of the knee cannot be cured, the pain associated with the disease can be controlled with intra articular joint injections.


Our injections are performed under real-time ultrasound guidance. This enables the physician to see exactly where the solution is being placed, allowing precise injection into the affected joint. Because ultrasound does not use x-ray, there is no radiation exposure for the patient and the entire procedure can take as little as 15 to 30 minutes or less, depending on the number of joints being injected.
