Hyaluronic Joint Injection
Hyaluronic acid is one of the key components in human tissue that is responsible for the body’s flexibility and mobility. Recent studies have revealed that the hyaluronic acid can be used to help the patients suffering from knee and hip arthritis better known as osteoarthritis.
What is Hyaluronic injection used for?
Hyaluronic is used to relieve joint pain due to osteoarthritis. It is used for patients who do not get enough relief from simple painkillers, such as acetaminophen, or from exercise and physical therapy.
What is synovial fluid do in the joint?
The synovial fluid in the joint has four functions:
- It keeps the articulations slightly apart, protecting their coverings from wear and tear
- It lubricates the joint, helping it to work freely and easily
- It acts as a filter, letting nutrients reach the tendons and cartilage, but blocking the passage of harmful cells and substances
- It eliminates harmful inflammatory proteins, reducing pain and swelling when the joint is injured.
The most important component of synovial fluid is a substance called Hyaluronic. It is this substance that lets synovial fluid perform the different functions all at the same time.
Why should I take this injection?
Hyaluronan injections have been shown to have the following beneficial effects on joints:
- They replace some of the normal ingredients found in synovial fluid (hyaluronans) improving the lubricating ability.
- The Hyaluronan coats the lining of the damaged joint surfaces and lining, covering pain nerve endings. This reduces pain and protects the joint surfaces from joint inflammation.
- Hyaluronans also act directly to reduce inflammation in a joint.
What should I do after the injection?
To gain the most benefit from this injection it is important that you rest the joint from any strenuous activity for 1-2 days.
What are the possible adverse events to the injection?
- When you have the first injection into the joint; pain, swelling, heat, redness, and/or fluid build-up around the joint may happen. These reactions were generally mild and did not last long, but sometimes fluid accumulation was considerable and painful; cases where the swelling is extensive and painful should be discussed with your doctor.
- Rare cases of knee joint infection have been reported after such injections.
- Rashes, hives and itching have been seen in patients after treatment.
- Other less common side effects have been: muscle pain, flushing and/or swelling of your face, fast heartbeat, nausea, dizziness, fever, chills, headache, difficulty breathing, swelling in your arms and/or legs, prickly feeling of your skin, and in rare cases a low number of platelets in the blood.
