Hyaluronic acid injections are a minimally invasive treatment option for knee osteoarthritis, a condition that causes pain, stiffness, and swelling due to the destruction of knee bone and cartilage. The injections are performed as a quick and easy outpatient procedure, after applying a topical anesthetic over the knee. Hyaluronic acid helps lubricate the joint, allowing it to move easily without pain. Patients should be aware of the symptoms and take nonsurgical treatments for mild cases. However, some moderate to severe cases may not respond to nonsurgical treatment, and hyaluronic acid injections may be recommended. Our Board-Certified and Fellowship-Trained specialists can help determine if this is an appropriate treatment option.
Hyaluronic acid injections are a minimally invasive treatment option for knee osteoarthritis that does not respond to nonsurgical treatment. Injections are performed as a quick and easy outpatient procedure. A topical anesthetic is applied over the knee before the procedure begins—anesthesia, intravenous sedation, or pain medications are not needed. After the patient is relaxed and the knee is numb, the procedure begins:
Patients return home or to work and normal activities almost immediately after their procedure. Minor soreness and swelling are easily controlled with ice and elevation. Depending on the brand of hyaluronic acid used, repeat injections may be performed at 1 or 2-week intervals.
Knee osteoarthritis slowly destroys knee bone and cartilage and decreases hyaluronic acid concentration in the joint fluid. This is important because hyaluronic acid helps lubricate the joint, allowing it to move easily without pain or bone on bone rubbing. Symptoms patients should be aware of include:
Nonsurgical treatment options effectively treat mild cases of knee osteoarthritis. Some moderate to severe cases of knee osteoarthritis may not respond to nonsurgical treatment and hyaluronic acid injections may be recommended. Patients who experience symptoms are encouraged to make an appointment with our Board-Certified and Fellowship-Trained specialists to see if hyaluronic acid injections are a treatment option that can help improve your symptoms.
