Fluid Replacement Therapy: Image Guided
Viscosupplementation with Hyaluronates:
We bend our knees a million times in a year. The lubricating fluid, called synovial fluid, helps this process acting like a lubricant and shock absorber to protect your knee. To understand viscosupplemention and its benefits, let's take a look at the normal knee and osteoarthritis (OA).
The knee joint is where the femur (thigh bone) and tibia (shin bone) come together. A third bone, the triangular-shaped patella (knee cap), lies across the front of the joint to protect it. As in our other joints, a layer of protective cartilage covers the ends of the bones to allow smooth movement. Special to the knee are two pads of protective tissue called menisci. The entire joint is encased is a capsule lined with a membrane called the synovium which generates a fluid that acts as both a lubricant and a shock absorber. This fluid is called synovial fluid. Various ligaments and muscles support, stabilize and power the joint. Although there are many problems associated with knee pain, the most prevalent joint disorder is osteoarthritis. Osteoarthritis can be due to a predisposition to its development but also often is a result of repetitive micro traumas over many years, an injury left untreated such as a torn meniscus and being overweight. The end result of osteoarthritis of the knee is often severe cartilage loss resulting in significant pain particularly while weight bearing (walking), getting up from a chair and sometimes at night.
Through this process of progressive osteoarthritis, the components of the synovial fluid often breakdown, resulting in diminished shock absorbing characteristics. This loss of shock absorption results in less protection of the knee during movement. One such component of the synovial fluid is hyaluronic acid (HA), which is responsible for the synovial fluid's ability to lubricate and act as a shock absorber in the knee. When one has knee OA, the concentration of HA in the synovial fluid is reduced causing a loss of shock absorbing and lubricating properties. This results in increased joint pain, stiffness and possibly an onset or worsening of osteoarthritis.

How Is It
Studies have shown that about 25 % of blind injections have delivered the medication into fat tissue around the knee instead of the knee joint itself. Therefore we at Pain Management Associates perform viscosupplementation injections under fluoroscopy, minimal x-ray in order to assure the best chance to benefit from fluid replacement therapy.
