Knee Pain Treatment in St. Louis, MO

You stopped taking the stairs. Then you stopped walking as far. You plan trips by whether there will be enough seating. Your knee has quietly reorganized your life.

This is what chronic knee pain does. And it does it gradually enough that many patients adapt to a smaller life rather than seeking treatment that might actually change things.

At STL Pain Center, physical therapist Anissa Wheeler and Dr. Andrew Morningstar work with knee pain patients across South St. Louis County who have often been told surgery is their only meaningful option. For many, it is not. Gel shots have helped patients like Lester Brannam, who came to us at age 71 having been told he needed knee replacement surgery, complete five weekly injections with Anissa Wheeler and walk out of their last session with dramatically improved function.

Understanding Knee Pain

Knee pain affects more than 25 percent of adults and is among the leading causes of disability in older Americans. It encompasses several different conditions with different mechanisms, though osteoarthritis and cartilage degeneration are by far the most common in adults over 50.

The knee is a complex joint carrying the weight of the entire body through thousands of loading cycles every day. As cartilage thins with age or injury, the joint loses its shock-absorbing capacity. The synovial fluid that lubricates the joint becomes less concentrated with hyaluronic acid. Bone surfaces begin to contact each other under load, producing friction, inflammation, and pain. This cycle becomes self-reinforcing: inflammation degrades cartilage; less cartilage means more inflammation.

What most standard care misses is that this cycle can be interrupted non-surgically. Hyaluronic acid injections restore joint lubrication. PRP therapy stimulates tissue repair and reduces inflammatory markers at the joint. Together or individually, these treatments have produced clinically significant improvement for patients who were told surgery was their only option.

STL Pain Center specializes in this kind of regenerative knee care. If you are managing knee pain that has limited your activity, schedule an evaluation today.

Common Causes of Knee Pain

Osteoarthritis The primary cause of chronic knee pain in adults over 50. Osteoarthritis involves gradual breakdown of the cartilage that protects the joint surfaces, leading to bone-on-bone contact, chronic inflammation, and increasingly limited range of motion.

Prior Injuries and Trauma ACL tears, meniscus damage, and fractures alter knee mechanics even after the acute injury heals. Long-term, these structural changes accelerate cartilage loss and increase osteoarthritis risk.

Overuse and Repetitive Loading Physical work, walking on hard surfaces, and repetitive knee-loading activities common among South St. Louis County residents contribute to cartilage wear and soft tissue inflammation over time.

Excess Body Weight Each pound of excess body weight adds approximately four pounds of pressure to the knee during walking. For patients managing both knee pain and excess weight, STL Pain Center’s Medical Weight Loss program addresses both conditions simultaneously.

Inflammatory Conditions Rheumatoid arthritis and other inflammatory joint conditions can accelerate knee cartilage damage and produce synovitis that worsens pain beyond what structural wear alone would cause.

Common Symptoms of Knee Pain

Knee pain symptoms vary based on the underlying cause. Some of the symptoms that benefit from an evaluation at STL Pain Center include:

• Pain when climbing or descending stairs
• Stiffness after sitting or lying down
• Grinding or crunching sensation with movement
• Swelling around the joint
• Reduced range of motion
• Pain during or after walking
• Instability or feeling the knee may give out
• Pain at rest or at night

How We Treat Knee Pain in St. Louis

At STL Pain Center’s Orthopedic Clinic, we treat knee pain using regenerative and viscosupplementation approaches that address the structural and inflammatory mechanisms behind your pain without surgery.

Hyaluronic Acid Injections Our most frequently used knee treatment. Gel shots replenish the joint’s natural lubrication, reduce friction between cartilage surfaces, and provide pain relief that typically lasts six months to a year or longer. Patient Lester Brannam completed five weekly sessions and avoided the knee replacement surgery his doctor had recommended. Anissa Wheeler manages these sessions with care that has earned five-star reviews from our knee patients. Learn more about hyaluronic acid injections.

PRP Therapy For patients with knee pain driven significantly by inflammation and tissue breakdown, platelet-rich plasma therapy delivers concentrated growth factors to the joint to stimulate repair. PRP is particularly effective for patients with active inflammatory changes or significant soft tissue involvement alongside cartilage loss. Learn more about PRP therapy.

Regenerative Therapy Patients with complex knee conditions involving multiple tissue types benefit from our coordinated regenerative therapy protocol, which combines approaches to address the full picture. Learn more about regenerative therapy.
