Joint injections are of main two types. One is with cortisone, which reduces joint inflammation, most commonly in the hips, knees and shoulders.
The second type is with hyaluronan injections — also called viscosupplementation. These medications work like a cushioning fluid in the joints – to reduce the ‘bone on bone’ bumping and grinding in the knees.
Whether from an acute injury or long term degeneration, our joints, including their surrounding capsules, ligaments, and muscles can become inflamed. While initially the inflammation our bodies produce serve a purpose, it can also damage normal tissue. Sometimes, the debris from the inflammatory process coagulates and forms hard masses, scarring, and/or trigger points in the muscle or joint, preventing normal function from returning.
Injection of corticosteroids can help reduce the inflammation, preventing tissue damage and scarring, as well as decreasing pain and restoring function. The injection can be done with ultrasound or x-ray fluoroscopic guidance to ensure best results.
