If you've been dealing with knee pain for a while and feel like you've tried just about everything, shockwave therapy might be worth a closer look. It's one of those treatments that a lot of people haven't heard of yet, but it has a solid and growing body of research behind it. At Pelphrey Chiropractic here in Lexington, we use shockwave therapy as part of a broader approach to helping patients with stubborn musculoskeletal pain get their lives back.
What Is Shockwave Therapy?
Shockwave therapy, often called Extracorporeal Shock Wave Therapy (ESWT), uses focused acoustic (sound) waves to stimulate healing in damaged or degenerated tissue. A handheld device is applied to the skin over the painful area, and it delivers rapid pulses of energy into the tissue beneath. The whole process is quick, typically 5 to 10 minutes per session, and most patients need only 3 to 6 sessions spaced a week apart.
It's worth clarifying what "shockwave" actually means here, because the name can sound a little alarming. These aren't electrical shocks. The waves are mechanical, similar in nature to the sound waves used in diagnostic ultrasound, just delivered at a higher energy level to trigger a specific biological response in the tissue.
How Does It Help Knee Pain Specifically?
Knee pain can come from several different sources, and shockwave therapy tends to work best when the root cause involves tendon irritation, calcification, or chronic inflammation in the soft tissue around the joint. Some of the most common knee conditions it's used for include:
Patellar Tendinopathy (Jumper's Knee)
This is a very common cause of knee pain, especially in active adults and athletes. The patellar tendon connects your kneecap to your shin bone, and when it becomes overloaded or degenerates over time, it can cause persistent pain at the front of the knee. Shockwave therapy has been shown in multiple studies to improve outcomes for patellar tendinopathy, often in cases where other conservative treatments have plateaued.
Calcific Deposits Around the Knee
Sometimes calcium builds up in tendons or bursae around the knee, causing sharp, localized pain. Shockwave therapy can help break down these calcifications so the body can reabsorb them more naturally.
Chronic Soft Tissue Inflammation
When pain has been present for months, the tissue involved often shifts from an active inflammatory state to a more degenerative one. Shockwave therapy re-stimulates a healing response in that tissue, essentially encouraging the body to "restart" the repair process in an area that has gotten stuck.
What Actually Happens in the Tissue?
This is where the science gets interesting. When shockwave energy is delivered to the tissue, several things happen at the cellular level. Blood flow to the area increases. Growth factors that stimulate tissue repair are released. Nerve fibers that transmit pain signals are temporarily disrupted, which can reduce pain fairly quickly. Over time, the treatment encourages the formation of new collagen, which is the structural protein that tendons and connective tissue are made of.
Essentially, shockwave therapy works with your body's own healing mechanisms rather than masking the problem.
Is Shockwave Therapy Right for You?
It's not a universal fix, and like any treatment, it works better for some conditions and some patients than others. It tends to be a good option when:
- Pain has been present for at least 3 months and hasn't responded well to rest, ice, or standard physical therapy
- Imaging or clinical exam points to tendon involvement or calcification
- You want to avoid surgery or try conservative options first
- Corticosteroid injections have provided only temporary relief
It's generally not recommended during pregnancy, over areas with active infection or open wounds, or in patients with certain blood clotting conditions. A thorough evaluation before starting treatment is important, which is why we always begin with a full assessment of your history and a physical exam.
What to Expect During Treatment
Most patients feel some discomfort during the session, often described as a tapping or pressure sensation that can be mildly uncomfortable over sensitive areas. It's generally well tolerated, and no anesthesia is needed. Afterward, there may be some temporary soreness, similar to what you'd feel after a deep tissue massage. That typically resolves within a day or two.
It's also worth knowing that improvement is usually gradual. Some patients notice a difference after the first or second session, while others see the biggest change in the weeks following their last treatment as the tissue continues to remodel and heal.
How We Use It at Pelphrey Chiropractic
Shockwave therapy is one tool in a broader toolkit. We combine it with hands-on chiropractic care, targeted rehabilitative exercises, and patient education so that the underlying movement patterns and mechanics that contributed to the problem in the first place get addressed too. You can learn more about the full range of services we offer at Pelphrey Chiropractic to get a sense of how we approach musculoskeletal care.
If you're a Lexington area patient dealing with persistent knee pain and wondering whether shockwave therapy might help, we're happy to talk it through with you.
