Tennis Elbow: What Most People Get Wrong
If you’ve made it past forty, there’s a good chance you’ve already met tennis elbow or you will. It has a misleading name as most people who develop it have never picked up a racket in their lives, and professional tennis players are among the least likely to get it. The clinical name is lateral epicondylitis: pain at the outer side of the elbow, where the tendons of the wrist extensors attach to the bone. It is, by almost every definition, a condition of midlife.
I treat many cases of tennis elbow every week. It’s frustrating for both patient and therapist , partly because a lot of what we’ve been taught about orthopedic pain and rehabilitation simply doesn’t hold up when it comes to the elbow.
Tennis Elbow Diagnosis
Tennis elbow is a clinical diagnosis. That means it’s identified through observation, palpation, and the pattern of pain , not through a scan. Diagnostic imaging has very little, often zero, utility here. An MRI of the elbow is largely a waste of time and money, and more importantly, it can cause real harm by frightening the patient with findings that have no clinical match on how they actually feel.
Tennis elbow is a degenerative condition. The tendons of the elbow and surrounding tissue become disorganized , usually not as a result of some injury event, but as a natural consequence of aging. This happens in all of us in the second half of life. What determines whether the elbow is painful or not isn’t what the MRI shows. It’s the tendon’s capacity to adapt to load. An MRI can reveal a perfectly healthy-looking tendon in someone who can barely lift a bottle of olive oil. And it can show disorganized tissue in someone who feels nothing at all.
What Actually Causes Tennis Elbow
Tennis elbow is not a wear-and-tear condition. If it were, professional athletes would be the most affected group and they’re not. A tendon is designed to bear load. The problem arises when the load placed on the tendon exceeds its capacity to adapt. When that threshold is crossed repeatedly, the tissue sustains damage. The body responds by rebuilding but not cleanly. Collagen fibers are laid down in a disorganized pattern. New blood vessels form, bringing with them new nerve endings. Those nerves generate pain and that process is what we’re actually treating.
Metabolic health plays a larger role in tendinopathy than most people realize, and tennis elbow is no exception. Insulin resistance, elevated lipids, and high uric acid , even at levels that don’t yet produce gout , are all detrimental to tendons. Uric acid above optimal levels deposits micro-crystals directly into tendon tissue, triggering local inflammation. Estrogen deficiency also matters: it impairs the body’s ability to synthesize collagen, and that shows up not just in the face skin, but in the tendons.
What Doesn’t Work
A steroid injection has a limited role here : managing debilitating pain in the short term. It is not a treatment for tennis elbow, and it is not a cure. The research on this is consistent : patients who receive corticosteroid injections tend to do worse on long-term follow-up than those who receive conservative care and rehabilitation.
There’s also the uncomfortable reality that many clinical guidelines recommend observation as a first-line approach. The reasoning isn’t wrong: most cases of tennis elbow resolve on their own, given enough time. The window is eight to twelve months, sometimes up to two years. For patients who are willing to wait it out, it often works. For everyone else , and that’s most people , rehabilitation offers a way through that doesn’t require enduring years of chronic pain and hoping for the best.
The Rehab Protocol
The single worst thing you can do for a painful tendon is rest it. Immobilizing the elbow, splinting it, avoiding all load are counterproductive strategies . Tendons need stimulus to remodel. The goal of rehab is not to protect the tendon from stress, but to introduce stress strategically.
In the first weeks, I recommend isometric exercises. The tendon is loaded slowly and held under tension without movement. This is enough to begin stimulating tissue repair and strengthen the healthy fibers that remain, without overloading damaged tissue. Done one to three times a day, isometrics create a foundation and also help with pain control.
As pain becomes more tolerable, eccentric loading is introduced , exercises where the muscle lengthens under tension. From there, the goal is progressive overload: gradually increasing the demand on the tendon over time This protocol It’s what keeps the tendon healthy long-term and prevents recurrence. Rest is never the answer. Not at the beginning, not at the end, not anywhere in between.
Exercises
Phase 1: Isometrics (Weeks 1–3)
Begin with pain-reducing isometric exercises while symptoms calm down and you arrange evaluation if needed.
Phase 2: Eccentric and Isotonic Loading (Weeks 3–8)
Progress to slow, controlled strengthening exercises focused on wrist extension and tendon loading.
Phase 3: Building Capacity (Weeks 8–16)
Add grip strengthening, carries, and forearm-focused compound movements. Increase load gradually.
Phase 4: Return to Full Function (Months 4–6)
Gradually return to heavier lifting, sport-specific activity, and full function while continuing progressive strengthening.
Acupuncture and Dry Needling for Tennis Elbow
Randomized controlled trials show that acupuncture has moderate benefits for tennis elbow, primarily around pain management. It outperforms both PRP injections and steroid injections, and performs best when used alongside a structured rehab protocol rather than as a standalone treatment.
In my clinical practice, I typically recommend one to two acupuncture sessions per week in the early stages — not to replace loading, but to reduce pain enough that loading becomes possible. The primary points target the wrist extensor muscles.
Dry needling of the forearm has also shown strong results. By addressing trigger points in the extensor muscles, it releases tension at the tendon attachment and creates a local response that supports tissue healing. For many patients, the combination of dry needling and a graded loading protocol gets results faster than either approach alone.
The Reseach
Bottom Line
Tennis elbow is common, often mismanaged, and stubbornly misunderstood. Imaging won’t guide you. Injections won’t fix it. Rest will make it worse. What works is progressive, strategic loading , started early, sustained over time and supported by pain management tools like acupuncture when needed, and backed by attention to the metabolic factors that affect every tendon in the body.
It takes patience. But it resolves.
