Knee OA Management: 8 Key Benefits of Injection Therapy

May is Arthritis Awareness Month. For Dr. Okezie N. Okezie and our team at Interventional Sports and Pain Management Associates, there’s no better time to take a closer look at the benefits of injection therapy for persistent osteoarthritis (OA) joint pain and stiffness. 

As a board-certified interventional pain management specialist serving Houston-area patients, Dr. Okezie knows just how debilitating OA symptoms can be — especially when they affect a weight-bearing joint like the knee. Here’s how injection therapy can help. 

Knee osteoarthritis is a common problem

Arthritis is an umbrella term for dozens of conditions that cause joint inflammation, pain, and stiffness. Over 58 million American adults have some form of the disease; of those, nearly 26 million people live with arthritis-imposed activity or mobility limitations.    

Osteoarthritis (OA), also known as degenerative joint disease, is the most common cause of joint pain. This “wear-and-tear” form of arthritis occurs when cartilage, a slippery tissue that cushions the ends of bones within your joints, gradually wears away. 

OA-driven cartilage breakdown damages the joint, triggering inflammation, pain, and stiffness that can undermine your strength, limit your range of motion, and impair your mobility. Knee joints develop OA at a higher rate than other weight-bearing joints. 

When knee OA pain and stiffness persist

Early on, knee OA typically improves with regular low-impact exercise and weight loss, as needed. During symptom flares, conservative care — such as rest, cold therapy, bracing, and taking anti-inflammatory pain relievers — can often help. 

As OA continues to advance, however, getting relief from knee pain and stiffness usually means supplementing at-home care strategies with physical therapy and next-level pain-relief procedures. That’s where injection therapy comes in. You may benefit from:   

• Corticosteroid (cortisone) shots
• Hyaluronic acid (HA) injections 
• Genicular nerve blocks (GNBs)

Using fluoroscopy (live X-ray) or ultrasound imaging guidance for precise placement, these injections work in various ways to alleviate knee OA pain for weeks or months at a time. 

Corticosteroids calm inflammation, GNBs mute or block pain signals, and HA injections are a form of viscosupplementation (also called “gel shots”) that improve joint lubrication. 

8 Benefits of injection therapy for knee OA

For persistent OA symptoms that no longer improve significantly with conservative care — but aren’t yet severe enough to warrant a total knee replacement — injection therapy is an ideal stop-gap solution. Key benefits include:

1. Rapid pain reduction

Steroidal medication injections, nerve blocks, and gel shots act rapidly to alleviate knee pain, typically providing significant relief within 24 hours (and sometimes faster).  

2. Reduced inflammation

Joint injections actively “put out the fire” of the inflammatory cascade caused by OA damage, helping to significantly reduce joint swelling, stiffness, and discomfort. 

3. Improved joint function

By delivering lasting relief from knee pain and stiffness, injection therapy can improve joint function, restore a better range of motion, increase flexibility, and support more fluid movement.  

4. Confident mobility 

When knee joint function improves substantially, you’re more confident on your feet: Smooth, predictable joint motion translates to less discomfort and hesitation during routine activities like walking and going up and down the stairs.

5. Physical therapy support

Injection therapy provides a “window of relief” that allows you to participate more fully in physical therapy exercises. An OA-centered PT plan works to strengthen, stabilize, and support arthritic joints — and helps slow disease progression and prevent further joint damage.  

6. Delayed need for surgery

Joint replacement surgery is the only way to resolve advanced knee OA. Injection therapy can help you manage persistent OA symptoms more effectively, allowing you to delay the need for knee surgery — often for up to several years.     

7. Targeted delivery

By delivering potent pain relief medication directly to your arthritic knee joint, injection therapy significantly reduces the need for taking oral pain relief medications that come with systemic risks and side effects. 

8. Minimally invasive relief   

Injection therapy is a minimally invasive treatment that delivers rapid relief, so you can get back to your usual routine with no downtime — and back to your active life in no time.
