Synvisc Injection – All About the Treatment

Osteoarthritis is a common condition that affects around 15% of individuals aged 30 and older, with estimates suggesting that nearly 1 billion people will be living with it by 2050. This degenerative joint disease, characterized by pain and stiffness, is prevalent among older adults and is heavily influenced by factors such as aging and obesity.

One treatment option for osteoarthritis is Synvisc, an injectable hyaluronic acid product that supplements the joint’s natural synovial fluid. Synvisc works by enhancing lubrication and cushioning within the joint, aiming to reduce pain and improve mobility—key to addressing the functional limitations often associated with this condition.

This article will explore the Synvisc injection, examining its effectiveness, how it works, and what patients can expect during treatment. 

Key Takeaways

• Synvisc is an injectable treatment containing hyaluronic acid, designed to relieve knee pain caused by osteoarthritis by improving joint lubrication and cushioning.

What is Synvisc Injection?

Synvisc is a viscosupplement designed to relieve knee pain caused by osteoarthritis. Its key component is hyaluronic acid, a substance naturally found in the body’s joints that helps maintain smooth movement and cushioning. This formulation is particularly useful for individuals whose natural joint fluid has degraded due to osteoarthritis, leading to pain and stiffness.

Synvisc’s mechanism of action involves enhancing the joint’s synovial fluid, which lubricates and cushions the knee. By mimicking this natural fluid, Synvisc helps the joint move more smoothly and with less discomfort. This treatment is particularly beneficial for those who have not experienced relief from other medications or therapies.

According to Synvisc prescribing information, a single injection can provide relief for up to six months, significantly improving mobility and reducing pain. This extended pain relief allows individuals with osteoarthritis to remain active for more extended periods without the discomfort commonly associated with knee movement. Synvisc aims to improve overall joint function and quality of life by reducing pain and enhancing mobility.

The Synvisc Injection Process

• Preparing for the Injection: Before getting a Synvisc injection, inform your doctor about any medications you are taking. Some medications (e.g., blood thinners) may need to be temporarily stopped before the procedure. If you also have any infections or issues with your knee joint, disclose these to your doctor so they can evaluate whether the injection is appropriate at that time.
• The Injection Procedure: Synvisc is administered directly into the knee joint using a fine needle. The process is quick and typically lasts just a few minutes. Still, it requires precision to ensure the hyaluronic acid is injected into the joint space where it can provide optimal relief. This is usually done in a clinical setting and does not require anesthesia.
• What to Expect During and After the Injection: You can return to normal activities quickly, but give it a few days before doing anything heavy. You should notice less knee pain from osteoarthritis for up to six months after getting the shot.

Expected Outcomes and Post-Treatment Care

After receiving a Synvisc injection, most patients experience some mild discomfort or swelling at the injection site. These side effects are typically short-lived and can be managed with over-the-counter pain relievers, such as acetaminophen. Applying a cold compress to the knee can also help reduce any initial swelling or tenderness.

It’s important to avoid anti-inflammatory medications like ibuprofen or aspirin unless your doctor advises otherwise, as these can interfere with the body’s natural healing process following the injection.

Physical Activity and Rehabilitation

You can also resume light activities the same day, but avoiding strenuous exercise or heavy lifting for the first 48 hours is crucial. Low-impact activities, such as walking or swimming, are generally encouraged as they help maintain joint mobility without putting too much pressure on the knee. 

Depending on your specific needs, your healthcare provider may recommend a physical therapy program to help strengthen the muscles around the knee and improve joint function, enhancing Synvisc’s effects over time.

Follow-Up Appointments and Monitoring Progress

Regular follow-up appointments with your doctor are essential to monitor how well your knee responds to the treatment. These check-ins allow your healthcare provider to assess your progress, manage any side effects, and decide whether additional Synvisc injections are necessary.

Typically, Synvisc’s effects last for up to six months, but your doctor may recommend repeat treatments if needed. Tracking your knee’s range of motion, pain levels, and overall function during this period can help your doctor make informed decisions about your ongoing care.

Conclusion

The Synvisc injection provides an effective option for those seeking relief from knee pain caused by osteoarthritis, especially when other treatments have failed. Enhancing joint lubrication and cushioning helps many patients experience improved mobility and reduced discomfort, allowing them to regain the ease of movement they once had.

Following post-treatment care guidelines is essential for maximizing the results and ensuring long-lasting relief from knee pain.
