A pulled hamstring that keeps tightening up. A knee that swells after every game. A shoulder that will not let you serve. An ankle that never felt right after that sprain. Sports injuries that linger keep you on the sidelines, and rest only gets you so far. Dr. Ilana Etelzon finds what is holding back your recovery and treats that, so you can get back in the game.
Sports injuries happen to weekend warriors, lifelong runners, pickleball players, and people getting back into shape at every age. After 40, tendons and ligaments heal more slowly and are more prone to strain, so an injury that would have healed in weeks at 25 can drag on for months. Rest makes the pain fade, and the tissue often stays weak.
Lasting recovery comes from finding the specific tissue that was hurt, the reason it is slow to heal, and what overloaded it in the first place, such as weak supporting muscles, an old injury, or a training change. Getting back to sport too soon, or not at all, usually comes from skipping that step.
Most injuries that linger have more than one of these at work at the same time. That is why rest alone rarely gets you back, and why your plan should match your own mix.
Achilles, patellar, hamstring, and shoulder tendons can stall partway through healing and stay weak and sore.
Torn fibers that heal loosely leave a joint unstable or a muscle prone to straining again.
Meniscus tears, labral tears, and cartilage injuries change how a joint moves and can lead to early arthritis.
After an injury, the muscles around it weaken, which puts more strain on the healing tissue.
An earlier sprain or strain that never fully healed changes how you move and loads other areas.
A sudden jump in training, a new sport, or a technique flaw can overload the same tissue again and again.
Your first visit is built around one question: what is keeping this injury from healing? Dr. Etelzon answers it with the same careful steps every time.
You leave knowing what is holding back your recovery and what each part of your plan is for.
Diagnose all the sources of pain before treating any of them.
Image-guided regenerative care aimed at the damaged structures.
Strength and movement work so the area holds up under load.
Return to your activities and stay there.
Once the drivers are clear, Dr. Etelzon chooses treatments that aim at them directly. Injections are placed under ultrasound guidance, so they reach the exact injured tissue.
Concentrated platelets from your own blood, placed into an injured tendon, ligament, or muscle to help it heal stronger.
Learn about PRP injections ›Cells drawn from your own bone marrow, used for larger tears and joint injuries that need more support to repair.
Learn about stem cell injections ›Acoustic waves that restart healing in a stubborn tendon and help tight, injured muscles recover.
Learn about shockwave therapy ›A minimally invasive procedure that clears out damaged tendon tissue through a tiny opening, for tendons that have not responded to other care.
Learn about TenJet ›A focused laser that calms pain and swelling and helps tissue recover faster between sessions.
Learn about MLS laser therapy ›A step-by-step strength and movement plan, so you return to your sport ready and stay there.
See our regenerative procedures ›Cortisone can quiet pain for a short time, and it has a place. It can also weaken tendons and mask an injury that still needs to heal, so Dr. Etelzon uses it carefully in active people and pairs any short-term relief with treatment aimed at healing the tissue.
Sports injuries fall into a few common types. The type guides the plan, and your specific drivers decide it.
Achilles, patellar, hamstring, elbow, and rotator cuff tendons. PRP, shockwave, and tenotomy help stalled tendons heal. See rotator cuff treatment and tennis elbow treatment.
Ankle, knee, and elbow ligaments. PRP aimed at stretched or partly torn ligaments plus stability work can restore a steady joint.
Injuries inside the joint. PRP and bone marrow concentrate can reduce pain and support healing for many athletes. See labral tear treatment.
An honest note. A complete tendon or ligament rupture usually needs a surgeon. Dr. Etelzon will tell you plainly when that is the better path, and regenerative care can still help you recover after surgery.
Regenexx collects patient-reported outcomes from certified clinics across the country. Explore the live results below.
Like all medical procedures, regenerative procedures have a success and failure rate. Individual results vary.
Patients come to us wanting specific things back: a beach volleyball game, a pickup basketball run, a half marathon, a full season without a setback. That is what we treat toward.

Game time again
Your first visit is a consultation with Dr. Etelzon: your history, a hands-on exam, ultrasound, and a review of your imaging. Bring any X-rays or MRIs of your injury you have. If treatment makes sense, you leave with a written plan and a clear price before anything is scheduled.
Most regenerative procedures, including PRP and bone marrow concentrate, are not covered by insurance. Many patients use HSA or FSA funds, and monthly financing is available. See our payment and financing options.
Dr. Etelzon and her team treat sports injuries at four offices, so care is close to where you live, work, and play.
Call 1 (844) 959-7246 to reach any office.
One visit, a clear answer, and a plan built around your injury and the sport you want back. This is where the trying stops.
