Knee shots, or injections, can help you cope with the pain in the knee and hopefully enable you to be more active.

Which Injections are Used for Knee Pain?

The most common injection for knee pain is a steroid shot. It’s also called a cortisone or corticosteroid shot. The steroid shot can help to reduce the inflammation.

Steroid shots can give quick pain relief.

Another kind of shot is a hyaluronic acid injection.

What are the Side Effects of Shots for Knee Pain?

A common side effect of injections is pain and swelling the first day or two after the shot. It may help to apply ice at home for 15 to 20 minutes.

Injecting anything into a joint or tendon has a very small risk of harm.

When you have osteoarthritis, there may not be enough natural hyaluron in the joint, and the quality of that hyaluron may be poorer than normal. Cingal is used to supplement hyaluron to the knee joint. Cingal also contains a steroid which provides fast-acting pain relief by reducing inflammation, while the hyaluronic acid provides long-lasting pain relief. Cingal is given in a single shot directly into the knee joint.

Cinga Injection


How can Cingal Provide Relief From Osteoarthritis Knee Pain?

Cingal is the first single-injection treatment that quickly relieves your osteoarthritis knee pain while providing sustained pain reduction. It is used for patients who do not get adequate pain relief from simple pain relievers or from physical therapy.

Cingal combines the benefits of a trusted anti-inflammatory to relieve osteoarthritis knee pain. The anti-inflammatory component offers fast pain relief generally beginning 24 hours after administration and the hyaluronic acid offers effective osteoarthritis pain relief for 6 months or more.

Knee pain due to osteoarthritis (OA) can impact your lifestyle and daily activities. The most widespread form of arthritis, osteoarthritis, affects more that 1 in 10 Singapore citizens, with increasing trends of premature osteoarthritis from sporting injuries.

Injections are used to help in the management of osteoarthritis, but they are not a cure for the condition. They act by reducing symptoms such s pain and discomfort with the aim of improving function once more. As with other medicines, they should be used as a package, for example, alongside exercising or physiotherapy. The injections that we will cover in this article are called intra-articular injections – injections directly into the joint itself. They are therefore very different to the usual intramuscular injections (e.g. the flu jab) or subcutaneous injections (e.g. those used to administer insulin). There are two intra-articular injections commonly used in the management of osteoarthritis:

  • Corticosteroid injections
  • Hyaluronic acid

We will discuss these two injections and look at how effective they are, who they are suitable for, and potential side effects.

Corticosteroid intra-articular injections

Corticosteroids are hormones that are either produced naturally by the adrenal gland (found above the kidney) or produced synthetically. Most injection preparations are synthetic. They have various metabolic functions, but are used in osteoarthritis because of their potent ability to reduce inflammation. They were first used in the 1950s and to date most studies have concentrated on the knee joint, although there are some indications that it may also be beneficial for the hips. The vast majority of the research conducted with the knee joints confirms that corticosteroid injections are beneficial when compared to a placebo treatment. Today approximately 53% of doctors use these injections to help alleviate pain caused by osteoarthritis.

As mentioned earlier, the corticosteroid injection is not a cure for osteoarthritis but it can help relieve the pain and inflammation. The onset of pain reduction is usually rapid (between 24-48 hours) with the maximum effect being reached within a few days. Studies have shown that the benefits last up to 4 weeks in most subjects and up to 3 months in some patients who have effusions of the knee. They can be repeated up to four times per year for the knee joint although usually less often for hand joints. Research to date has not shown repeated injections to cause any deterioration of osteoarthritis in humans.

It is not uncommon following the injection to have a temporary, mild flare-up of knee pain occasionally accompanied by some inflammation. This is due to a natural reaction of the synovial fluid in the joint to the crystal steroid solution of the injection. It is usually an immediate side effect but it is not permanent, and the treatment for this is a cold compress.

Hyaluronic acid

Hyaluronic acid is a naturally occurring component of the synovial fluid and is also found in the cartilage. It is highly viscous and acts as a shock absorber within the joint. It also stores energy that can be released when there is rapid joint movement and acts as a lubricant when there is slower movement. It is thought it has a role in maintaining a healthy cartilage. In the osteoarthritic joint there is less naturally occurring hyalronic acid and it can be less viscous.

By injecting hyaluronic acid directly into the joint the depleted levels are replenished and hence ease the pain and improve function of the joint.

Hyaluronic acid injections are not a cure for osteoarthritis,but they are used to help reduce the symptoms  (pain, swelling, stiffness). The benefits are usually noticed between 2 to 5 weeks, although this can vary. The benefits usually last about 6 months.

Learn More About Viscosupplements

What is a viscosupplement?

A viscosupplement is a type of fluid that is injected directly into the knee to help lubricate and cushion the joint. Viscosupplements replace damage synovial fluid to help relieve pain and improve joint function.

What are viscosupplements made from?

Viscosupplements are made from a substance called hyaluronan. Hyaluronan is a natural substance found in the body and is present in very high amounts in joints. The body’s own hyaluronan acts like both a lubricant and shock absorber in the joint and is needed for the joint to work properly.

When should I consider a viscosupplement?

Viscosupplements are for people with Osteoarthritis of the knee who have not received enough pain relief from diet, exercise, and pain medication. If you’ve tried these options and are still feeling pain, ask our doctor if a viscosupplement could help.

What are the side effects?

Side effects with viscosupplements may include pain, swelling, or fluid build-up around the knee.

Autologous Platelet Rich Plasma, a new approach for healing muscle and ligament injuries.


What is Autologous Platelet Rich Plasma Therapy?

Autologous platelet rich plasma therapy (PRP) is a promising solution to accelerate healing of tendon injuries and osteoarthritis naturally without subjecting patients to significant risk. The philosophy is to merge cutting edge technology with the body’s natural ability to heal. PRP technology was intially developed 20 years ago to aide with wound healing and blood loss. Its benefits are now applied towards the facilitation of healing tendons and cartilage. In fact, PRP has been widely used for years in Europe to treat various tendon injuries.

How does PRP procedure work?

Using the patient’s own blood, specially prepared platelet are taken and then re-injected into the affected area. These platelets release substances known as “growth factors” that lead to tissue healing. For example, when you cut yourself, the body’s natural response is to attract platelets that release growth factors and facilitate healing. By concentrating the platelets we increase the release of growth factors which promotes the healing of tendons and cartilage.

The human body has remarkable ability to heal itself and by re-injecting concentrated platelets we are facilitating the natural healing process.

Is Platelet Rich Plasma Right For Me?

For most patient PRP offers a solid, alternative treatment for those who do not wish to have surgery. An initial evaluation will determine if PRP is a viable treatment option.

What are the benefit of PRP treatment?

Patients can expect to see significant improvement in symptoms; elimination of need for more traditional treatments such as medications, cortisone inceptions or surgery; and a dramatic return for function.

How soon can I go back to regular physical activity?

This treatment is not “quick fix” and is designed to promote long-term healing. The process of PRP requires time and rehabilitation. Patients who follow a course of physical therapy are likely to see the most improvement in the affected area. PRP accelerates and shortens the recovery process in chronic injuries and new acute injuries.

Prior studies on tennis elbow have demonstrated an 81% improvement in pain scores at six months and 93% reduction in pain follow up at 1-3 years.

Through regular follow-up visits your doctor can determine when you are able to resume regular physical activities.

How do I prepare for an injection?

Patients should schedule an evaluation to determine if PRP is a viable treatment option. An MRI and/or musculoskeletal ultrasound may be done prior to the injection to insure a proper diagnosis and rule out any condition best treated surgically.

The PRP injection usually takes an hour and is performed on an outpatient basis. Do not take anti-inflammatories one week before or after the injection as this may limit the treatment benefits.

Depending on a patient’s condition, a series of 1-3 injections may be required.

How do I care of the injection site after the treatment?

Initially the procedure may cause some localised soreness and discomfort. Patients may apply ice and elevation as needed. After one week the patient will likely begin rehabilitation program with physical therapy.

What are the significant side effects?

The risks are usually uncommon.
