Knee injections and viscosupplementation are at the forefront of non-surgical treatments for knee pain, particularly in cases of osteoarthritis. These procedures aim to alleviate pain, enhance joint mobility, and offer a potential delay in the progression towards surgical intervention.
By providing targeted relief directly within the affected joint, these treatments also aim to improve the patient’s overall quality of life, allowing for increased activity levels and a reduction in the use of oral pain medications.
Viscosupplementation involves injecting hyaluronic acid into the knee joint to alleviate pain and improve mobility in patients with osteoarthritis. Hyaluronic acid, a substance naturally present in synovial fluid, acts as a lubricant and shock absorber, facilitating smoother joint movements.
This treatment is especially suited for those who haven’t found relief through conventional methods such as medications or physical therapy. By restoring the synovial fluid’s natural properties, viscosupplementation can provide significant pain relief and improved joint function. It represents a key non-surgical option in the management of knee osteoarthritis symptoms.
Other than viscosupplementation, various types of knee injections offer alternative approaches to managing knee pain and promoting tissue healing.
Before receiving a knee injection, patients undergo a thorough evaluation, including a medical history review, physical examination, and possibly imaging tests, to determine the most appropriate type of injection. Patients are advised to discuss any medications or supplements they are taking, as some may need to be paused before the procedure.
Knee injection procedures are typically quick and performed on an outpatient basis. The skin around the knee is cleaned, and a local anaesthetic may be applied to minimize discomfort. Using sterile techniques, the chosen substance is injected directly into the knee joint. The procedure usually lasts just a few minutes, and patients often feel minimal discomfort due to the local anaesthetic.
Immediately following the injection, patients might experience mild soreness or swelling at the injection site, which usually subsides within a few days. Most individuals can resume their normal activities shortly after the procedure, although strenuous activities should be avoided for a specified period as advised by the physician. Patients are often encouraged to engage in a gentle range-of-motion exercise to aid in recovery.
Knee Injections encompass a wide variety of benefits that include:
These treatments can significantly reduce knee pain, allowing patients to engage in daily activities with greater ease and comfort.
By addressing the underlying issues in the knee joint, such as inflammation or lack of lubrication, patients often experience improved joint movement and flexibility.
For some individuals, knee injections can postpone or even eliminate the need for knee replacement surgery by managing symptoms effectively.
As minimally invasive procedures, knee injections usually require little to no downtime, enabling patients to quickly return to their normal activities.
Compared to surgical options, knee injections carry a lower risk of complications and side effects, making them a safer choice for many patients.
While knee injections and viscosupplementation are generally safe and effective, as with any medical procedure, they carry potential risks and side effects. These may include:
Ideal candidates for viscosupplementation typically include individuals experiencing knee pain due to osteoarthritis, particularly those who:
Patients with severe osteoarthritis or significant knee joint damage may not be suitable candidates, as viscosupplementation is less likely to be effective in the advanced stages of the disease. A thorough evaluation, including a review of medical history, physical examination, and possibly imaging studies, is necessary to determine whether viscosupplementation is an appropriate treatment option.
Recovery and rehabilitation from knee injections aim to enhance joint function and mobility with minimal interruption to daily activities.

The onset of relief from knee injections can vary depending on the type of injection and the individual’s condition. Corticosteroid injections may provide relief within a few days, while hyaluronic acid and PRP injections may take several weeks to show full effects.
The frequency of knee injections depends on the specific type of injection and the patient’s response to treatment. Generally, corticosteroid injections are limited to a few times a year to avoid potential side effects, while hyaluronic acid injections may be repeated every 6 months or as recommended.
Many patients who have had knee surgery can still benefit from knee injections, but it depends on the type of surgery and the current condition of the knee. A thorough evaluation is necessary to determine suitability for injections post-surgery.
Knee injections typically do not directly restrict your ability to travel. However, it’s advisable to avoid long periods of immobility, such as sitting on a flight or car ride, immediately after the procedure to reduce the risk of swelling or discomfort. Plan to move or stretch your legs periodically during travel to maintain circulation and joint movement.
