Getting Ready for Your Knee Gel Injection: What to Know
Viscosupplementation is a minimally invasive procedure designed to alleviate pain caused by osteoarthritis and other joint issues, especially in the knees. Proper preparation can help ensure the procedure goes smoothly and that you experience the best possible results. In this guide, we will walk you through what to do before, during, and after your appointment, including understanding the procedure, preparing your health and medications, what to expect, and post-treatment care.
Understanding Viscosupplementation for Knee Pain
What is viscosupplementation?
Viscosupplementation for knees is a minimally invasive treatment designed to alleviate pain caused by osteoarthritis. It involves injecting a gel-like substance called hyaluronic acid directly into the knee joint. Hyaluronic acid is a natural component of joint fluid, acting as a lubricant and shock absorber that facilitates smooth movement.
This procedure aims to supplement the decreasing levels of hyaluronic acid in the joint, thereby improving lubrication, reducing inflammation, and increasing mobility. It’s typically recommended for patients with mild to moderate osteoarthritis who haven't found relief with other non-surgical options like medications or physical therapy.
How does the procedure work?
The process usually involves a series of 1 to 5 injections over several weeks, often guided by imaging techniques such as ultrasound to ensure precise placement. Before the procedure, the healthcare provider may remove excess fluid from the joint if swelling is present.
During the injection, the skin is cleaned and sterilized, and local anesthesia is applied to minimize discomfort. The hyaluronic acid is then carefully delivered into the joint space. Post-injection, patients are advised to rest for 24 to 48 hours, avoiding heavy activity and pressure on the joint.
The injected hyaluronic acid enhances the joint’s natural lubrication, which can decrease pain, improve mobility, and delay the progression of osteoarthritis. Relief can last several months, and repeat treatments can be administered if symptoms reappear.
What are the expected benefits and limitations?
Many patients experience reduced joint pain, increased range of motion, and improved quality of life following viscosupplementation. Most report relief within a few weeks, with benefits potentially lasting up to six months.
However, the treatment does not repair cartilage damage or reverse osteoarthritis. Its effectiveness varies among individuals, with about 60% experiencing significant symptom improvement. It is less suitable for advanced cases of arthritis or those with joint infections or allergies to hyaluronic acid.
Additionally, while generally safe, potential side effects include temporary swelling, soreness, or allergic reactions. Serious complications are rare but can include infection or inflammation.
In summary, viscosupplementation offers a promising option for managing knee osteoarthritis symptoms, especially in early to moderate stages, by restoring joint lubrication and easing pain.

Pre-Procedure Planning and Medical Preparations
What should I do to prepare for a viscosupplementation knee injection?
Preparing for a knee viscosupplementation involves several important steps to ensure safety and maximize effectiveness. First, you should have a detailed discussion with your healthcare provider about your current health conditions and any medications you are taking. This helps determine if you need to stop certain drugs, especially blood thinners, anti-inflammatory agents, or supplements that can increase bleeding risk.
Imaging assessments, such as X-rays or ultrasound, are typically recommended before the procedure. These imaging techniques help evaluate your knee’s bone and joint structure, aiding your doctor in selecting the best injection site and approach—whether superolateral, superomedial, or anterolateral/anteromedial. Accurate placement is crucial for optimal results.
On the day of the injection, make sure the area around your knee is clean and free of lotions, creams, or powders. Wearing loose clothing is advisable for easy access to the joint, and you may be asked to avoid eating or drinking certain foods or beverages if your provider suggests fasting.
It is essential to inform your physician about any recent infections or illnesses, as active infections can delay the procedure. Before the injection, your doctor may recommend stopping certain medications several days in advance to reduce the risk of bleeding or complications.
Following the procedure, plan to rest for approximately 12 to 24 hours. Applying ice packs to the knee can help ease soreness and swelling. It's recommended to avoid high-impact activities, strenuous exercise, or heavy lifting for a few days post-injection to allow your joint to recover properly. Always follow specific instructions provided by your healthcare provider to ensure a smooth and effective treatment experience.
During the Appointment: What to Expect
What can I expect during the viscosupplementation appointment?
When you arrive for your viscosupplementation, the process is usually quick and straightforward. First, the healthcare provider will thoroughly clean the skin around your joint—most commonly the knee—to reduce the risk of infection. Sterile technique is used throughout to ensure safety.
Next, local anesthesia is often applied to numb the area, making the procedure more comfortable. Depending on the case, imaging guidance such as ultrasound or X-ray may be used to accurately position the needle within the joint.
The physician then carefully inserts a fine needle into the joint space and injects the hyaluronic acid or similar lubricant. You might feel some pressure or mild discomfort during this step, but it typically does not cause significant pain.
Once the injection is complete, the needle is removed, and a bandage is placed over the site. Afterward, most patients can return home right away. Mild soreness, swelling, or warmth at the injection site are common and usually resolve within a few days.
It is advised to rest for a short period post-procedure and apply ice if any swelling or discomfort occurs. Overall, the appointment involves only a few minutes of your time and is performed in a clinical setting with minimal discomfort.
Post-Procedure Care and Recovery
Immediately following viscosupplementation, most patients can typically go home shortly after the procedure. It is important to prioritize rest during the initial 24 hours to allow the injected hyaluronic acid to settle properly within the joint. To optimize recovery, patients should avoid heavy, strenuous, or high-impact activities for at least two days. This precaution helps prevent any displacement of the fluid and reduces the risk of swelling or discomfort.
Managing soreness and swelling is straightforward. Applying ice to the injection site for 15-20 minutes at a time can significantly alleviate pain and reduce inflammation. Over-the-counter pain relievers such as acetaminophen or anti-inflammatory medications like ibuprofen can also be used as needed. These measures help ensure comfort as the joint begins to respond to the treatment.
Most patients experience some temporary soreness, mild swelling, or warmth at the injection site. These symptoms usually subside within a few days. It’s advisable to avoid baths, hot tubs, or swimming pools for at least 48 hours to prevent potential infections. Showering is generally safe and recommended.
For the first couple of days, activity should be limited to light movements, avoiding standing or walking for extended periods. Patients are encouraged to gradually resume normal activities once initial soreness diminishes, usually within a day or two. However, strenuous activities, running, or jumping should be avoided for at least 48 hours.
Signs of complications to watch out for include persistent or increasing pain, significant swelling, redness, warmth, fever, or discharge from the injection site. If any of these symptoms occur, prompt medical consultation is necessary to rule out infection or other adverse reactions.
Routine follow-up appointments are important to monitor the treatment’s effectiveness and to determine if additional injections are needed. The benefits of viscosupplementation typically begin to become noticeable within 3 to 5 weeks, with pain relief lasting from 6 to 12 months. Proper post-procedure care ensures optimal results and minimizes the risk of adverse effects.
Risks, Side Effects, and Cost Considerations
What are the risks and possible side effects associated with viscosupplementation?
Viscosupplementation with hyaluronic acid injections is generally considered a safe procedure. Most side effects are mild and short-lived. Patients commonly experience soreness, swelling, warmth, or redness at the injection site, which typically clear within a day or two. Sometimes, an injection flare occurs, characterized by significant swelling and pain, but this can usually be treated by draining the excess joint fluid.
Serious but rare complications include infection, allergic reactions, and pseudoseptic reactions. Symptoms such as severe swelling, redness, fever, or difficulty breathing require immediate medical care. Overall, the occurrence of serious side effects is uncommon, making viscosupplementation a low-risk intervention. Nevertheless, patients should remain vigilant and contact their healthcare provider if they experience persistent or unusual symptoms.
