Knee Pain Treatment: Gel Injections, Trigger Point Injections, PRP Injections

A number of things can cause knee pain, such as arthritis, bursitis, injuries, overuse, and lifestyle choices. Your pain may be acute, which means it’s new and may have come on suddenly, or it can be chronic, which means it perseveres for an extended period of time. We all get the occasional ache or cramp in our knees, but when this pain interferes with your daily activities and keeps you from living life to the fullest, knee injections may be able to help. 

At KneeCare Clinics, we help many patients eliminate hard-to-treat knee pain with therapeutic joint injections of all kinds, such as viscosupplementation, trigger point injections, platelet rich protein, and more. At KneeCare Clinics, our team of professionals can help you choose the best knee injection for your situation. We take the time to understand your specific issues and create an injectable treatment that works with your entire knee care journey.

Types of Injections

Some injections lubricate the joints surrounding the knee, making it easier for your body to move comfortably without friction or resistance, while others reduce inflammation, block pain-causing sensory neurons, or stimulate collagen production. The type of treatment you need depends on your condition and the severity of your symptoms. We do a variety of knee injections at KneeCare Clinics, but the most common injections we perform include:

Viscosupplementation

Viscosupplementation is a procedure in which a gel-like substance of hyaluronic acid is injected directly into the affected knee in order to replenish the diminished joint fluid. This enhances its lubricating properties and allows for smooth movement of the cartilage covered articulating surfaces of the joint, resulting in overall reduction of knee joint pain.

Trigger Point Injections

The trigger points in the leg muscles can cause pain to nearby parts of the body—such as an arthritic knee joint— because they irritate the nerves surrounding them. Trigger point injections relax the affected muscles and, thus, interrupt the nerve signaling pathways that cause knee pain. This results in a reduction of discomfort from trigger points and knee arthritis.

Platelet Rich Plasma Injections

Platelet-rich plasma (PRP) therapy involves removing the plasma from your blood. When a concentration of your own platelets are inserted via a syringe directly into the painful knee, it will trigger a natural response in the body to release cytokines, proteins, and other healing cofactors to repair cells and reduce pain.

Conditions We Treat

Bone on Bone

“Bone on bone” is another word for knee osteoarthritis, which is when the cartilage in your knee joint has been reduced because of wear and tear. When the padding is worn down altogether over time, it causes the bones to actually rub on one another causing immense pain. Knee injections can be a viable option to reduce the bone on bone sensation and subsequent pain.

Arthritis

With over 100 different kinds of arthritis, our specialists can effectively handle the common conditions that affect the knee the most, such as psoriatic arthritis, rheumatoid arthritis, and post-traumatic arthritis. Injection therapy is aimed at mitigating tissue degeneration, inflammation, and pain caused by arthritis.

Bursitis

Knee bursitis is an inflammatory condition in which the bursa near the knee joint becomes swollen because of overuse of the knee joint, such as kneeling for extended periods of time. Depending on which knee injection you choose, you can dramatically reduce the painful inflammation of the bursae in the knee joint.

Why Injections for Knee Pain?

While it will all depend on the injection you choose, there are certain benefits that everyone may take part in when using knee injections from KneeCare Clinics, such as:

  • Reduce pain – Studies performed for the many different kinds of injections generally show a reduction in overall joint pain. This reduction can start immediately or within a few weeks after treatment.
  • Avoid medication – Many people want to avoid relying on medication to treat their knee joint pain. Injections are performed once or over a small series of shots and will have lasting results long past the office visit.
  • Better mobility – Introducing lubricant can help make painful joints move more smoothly, reducing discomfort and helping improve function.
  • Delay the need for knee replacement surgery – Injections offer a very real solution to help you delay surgery or allow you to feel less pain as you wait for surgery to resolve your arthritis pain.
  • May be able to stimulate natural healing in the knee – Some injections may help stimulate the natural production of new cells or lubrication in the knee, which provides gradual symptomatic relief.
