Orthovisc and Monovisc Hyaluronic Acid Injections
What are Orthovisc and Monovisc Hyaluronic Acid Injections?
Orthovisc and Monovisc hyaluronic acid injections are medical injections that contain hyaluronic acid, a natural substance found in the fluid of joints. These injections are commonly used to treat knee pain caused by osteoarthritis.
Orthovisc is an intra-articular injection containing high-molecular-weight hyaluronic acid used for knee osteoarthritis. It is usually given as a series of 3–4 injections, typically one injection per week.
Monovisc is another intra-articular injection used for knee osteoarthritis. It contains cross-linked hyaluronic acid, which allows it to stay longer in the joint. It is designed as a single-dose injection, meaning the entire treatment may be completed in one injection.
How Do Orthovisc and Monovisc Hyaluronic Acid Injections Work?
Hyaluronic acid is a natural component of synovial fluid, the lubricating fluid in joints. In osteoarthritis, this fluid becomes thinner and less effective. Injecting Orthovisc and Monovisc injections help by:
- Lubricating the knee joint
- Reducing friction between bones
- Absorbing shock during movement
- Decreasing pain and improving joint mobility
This treatment is known as viscosupplementation, where artificial hyaluronic acid is added to the joint to improve the quality of joint fluid.
When are Orthovisc and Monovisc Hyaluronic Acid Injections Indicated?
Orthovisc and Monovisc hyaluronic acid injections are typically recommended for the treatment of knee osteoarthritis. Osteoarthritis is a degenerative joint disease that causes breakdown and eventual loss of cartilage in the knee joint, making the bones rub against each other, leading to painful movement.
Doctors may recommend these injections when:
- Pain from knee osteoarthritis does not improve with pain medicines, exercise, or physical therapy.
- Patients want to delay or avoid knee surgery.
How Should I Prepare for Orthovisc and Monovisc Hyaluronic Acid Injections?
To prepare for injections, inform your doctor about any allergies, medications, or medical conditions. The doctor examines the affected joint and may perform imaging if needed. Avoid taking blood-thinning drugs if advised. Wear comfortable clothing that allows easy access to the injection site. Stay hydrated and eat a light meal unless instructed otherwise. Follow any specific instructions given by your healthcare provider before the procedure.
What Should I Expect During Orthovisc and Monovisc Hyaluronic Acid Injections?
During Orthovisc or Monovisc hyaluronic acid injections, the doctor cleans the knee area with an antiseptic solution to prevent infection. A local anesthetic may be used to reduce discomfort. A sterile needle is then inserted into the knee joint, and the hyaluronic acid solution is slowly injected to improve joint lubrication. The procedure usually takes only a few minutes. You may feel mild pressure or discomfort during the injection, but it is generally well-tolerated, and most patients can return home shortly after the treatment.
What Happens After Orthovisc and Monovisc Hyaluronic Acid Injections?
After Orthovisc or Monovisc injections, patients may notice mild swelling, warmth, or discomfort in the knee for a short time. Doctors usually recommend resting the joint and avoiding heavy activities for 24–48 hours. Ice packs may help reduce swelling. Pain relief and improved joint movement typically develop gradually over the next few weeks. Results from injections may last up to 6 months.
What are the Risks and Benefits of Orthovisc and Monovisc Hyaluronic Acid Injections?
- Benefits: They help reduce knee pain, improve joint lubrication, decrease stiffness, and enhance mobility. In some patients, they may delay the need for surgery.
- Risks: Possible side effects include mild pain, swelling, redness, or warmth at the injection site. Rarely, infection, allergic reactions, or a temporary increase in joint pain may occur.
