Patellar Tendonitis

About Patellar Tendonitis

Patellar Tendonitis is a common athletic overuse injury, although it sometimes occurs in non-athletic populations. Your patellar tendon attaches your quadriceps muscles at the front of your thigh to your tibia (shin bone). During physical activity, the patellar tendon is subjected to great force loads as it straightens the knee during walking, running and jumping activities.

Patellar tendon dysfunction is sometimes called jumper’s knee due to its prevalence in sports that involve jumping. If left untreated, the tendon can begin to degenerate, leading to reduced mobility that can take you out of the game. New regenerative therapies and advanced technologies are able to halt patellar tendon degeneration and reverse it, to restore healthy tendon function.

Our Revolutionary Approach to Tendon Injuries Sets Us Apart

Our Revolutionary Approach to Tendon Injuries Sets Us Apart

Athletes know that a knee injury can be a career-ending event if not properly rehabilitated. Run-of-the-mill physical therapy clinics staffed by inexperienced clinicians often prescribe one-size-fits-all treatment protocols that fall short of restoring peak functional performance.

At NYDNRehab, we take a personalized approach to patient care. We understand that every patient has a unique anatomy, and every injury has its own peculiarities. Our one-on-one approach ensures that you get a patellar tendonitis recovery plan designed just for you, so you heal and return to play in the shortest time possible.

We use regenerative technologies that accelerate patellar tendonitis healing time at the cellular level, for the fastest possible recovery. But we don’t stop there — we do biomechanical analysis and feedback retraining to restore neural pathways between your brain and body, to eliminate compensation patterns adopted after your injury.

Our cutting edge technologies let us quantify motor parameters and track your progress, eliminating guesswork and ensuring that you recover completely from your injury before returning to sport. Our goal is to return you to the playing field, faster, stronger and more confident than you were before your injury.

Patellar Tendonitis Symptoms
and Causes


  • Patellar tendon pain

  • Lower kneecap tenderness

  • Swelling around your knee joint

  • Knee pain when jumping, running, or walking

  • Pain when bending and straightening your knee


  • Landing from a jump with an extended knee

  • Pivoting on a loaded knee

  • High velocity cutting and directional changes

  • Deficits in running gait mechanics

  • Inadequate recovery time between training sessions

Accurate Diagnosis is Key to
Successful Treatment


Because patellar tendonitis shares symptoms with other knee conditions like torn meniscus or ACL ruptures, it is imperative to get an accurate patellar tendonitis diagnosis before starting treatment. A wrong diagnosis can lead to ineffective treatment that wastes your time and money, and the wrong treatment modalities can make your condition worse.

At NYDNRehab, we use the highest resolution diagnostic ultrasound to visualize the structures of the knee and surrounding tissues. Patellar tendonitis ultrasound is superior to Xray or MRI because it lets us visualize your knee in real time, with the patient in motion and providing feedback. Ultrasound lets us trace the path of long structures like bones, nerves and muscles, to look for damage that can prolong your patellar tendonitis healing time.

Our in-house high resolution ultrasound imaging lets us quickly confirm your diagnosis of patellar tendonitis without having to wait for lab results, so we can begin to rehabilitate your tendon right away.

Treatment Options for Patellar Tendonitis

Treatment Options for Patellar Tendonitis

Patellar tendonitis treatment protocols vary, depending on the condition of the affected tissues and the degree of degeneration. Early treatment focuses on reducing inflammation and stimulating the healing process. As healing progresses, you may receive some or all of the following therapies:

At NYDNRehab, we take an active approach to treating patellar tendinosis. Some of our treatment methods include:

  • Physical therapy for knee tendonitis

  • Dry needling of the patellar tendon

  • 3D running gait analysis and retraining

  • Neuromuscular feedback training

  • Progressive eccentric loading

  • Blood flow restriction training

  • Ultrasound guided needling procedures

  • Regenerative therapies


Our Regenerative Therapies are Game-Changers
for Tendon Pain

Because tendons are made of tough collagenous fibers, they have limited vascularity, which can make them slow to heal. Regenerative therapies tap into your body’s innate healing mechanisms, creating an optimal environment for healing at the cellular level. Regenerative technologies are designed to jump-start the healing process and accelerate recovery, so you get the very best results in the shortest amount of time.

Focused Extracorporeal Shock Wave Therapy (ESWT)

Focused ESWT is used as a regenerative treatment for damaged tendon, muscle and bone tissue. This technology produces high frequency sound waves to stimulate the body’s own reparative mechanisms. It is especially effective for chronic degenerative tendon disorders and myofascial pain syndrome.

Extracorporeal Magnetic Transduction Therapy (EMTT)

EMTT is a fairly new technology that transmits high energy magnetic pulses to targeted tissues. The magnetic waves synchronize with the body’s own magnetic fields, causing a disturbance that triggers a regenerative response. EMTT waves can penetrate deep tissues up to 18 cm beneath the skin’s surface, to target difficult-to-reach tendons, muscles, bones and nerves.

Extracorporeal Pulse Activation Technology (EPAT)

Extracorporeal Pulse Activation Technology (EPAT)

Extracorporeal Pulse Activation Technology (EPAT)

EPAT, also known as defocused shock wave therapy, uses acoustic pressure waves to enhance blood circulation to targeted tissues. This speeds up the delivery of oxygen and nutrients to damaged tissues and stimulates cellular metabolism, to accelerate the healing process.

High Energy Inductive Therapy (HEIT)

HEIT uses electromagnetic fields to penetrate cells, tissues, organs and bones, to reactivate the electrochemical function of cells and cell membranes. HEIT generates a magnetic field 600 times stronger than the field of a normal magnet, to stimulate healing of nerves, muscles and blood vessels.

INDIBA CT9 Radiofrequency Device

Our INDIBA Tecar therapy machine converts electrical current into a stable radio frequency current of 448 kHz, designed to increase and stabilize the exchange of ions in damaged cells, evoking a regenerative response that accelerates healing. INDIBA can be used to successfully treat joint and muscle disorders, low-back pain, sports injuries, surgical incisions and various pain syndromes. Another therapeutic effect of INDIBA is extreme and prolonged cellular hyperthermia. Due to this effect, INDIBA therapy combined with manual therapy and soft tissue tissue manipulation enables instantaneous release to occur, significantly shortening the number and duration of physical therapy sessions. What is normally accomplished in two months of physical therapy can be accomplished in 3-4 sessions with INDIBA.

Ultrasound Guided Injection

Injection therapies use natural/neutral solutions that stimulate cellular repair by either nourishing or irritating the targeted cells. Guidance by ultrasound ensures that the injected substances hit their mark, for maximum effectiveness.

Focused Shockwave Therapy

Platelet Rich Plasma (PRP)

PRP therapy uses a sample of the patient’s own whole blood, which is spun in a centrifuge to extract a high concentration of platelets. When injected into damaged tissues, PRP initiates tissue repair by releasing biologically active factors such as growth factors, cytokines, lysosomes and adhesion proteins. The injected solution stimulates the synthesis of new connective tissues and blood vessels. PRP can help to jump-start healing in chronic injuries and accelerate repair in acute injuries.

Proliferation Therapy, aka Prolotherapy

Prolotherapy uses a biologically neutral solution, often containing dextrose, saline or lidocaine. The solution irritates the affected connective tissue, stimulating the body’s own natural healing mechanisms to encourage growth of new normal ligament or tendon fibers.

Electromagnetic Transduction Therapy (EMTT)
Prolozone Therapy

Prolozone Therapy

Prolozone therapy is a new regenerative needling procedure that takes Prolotherapy to the next level. With prolozone therapy, a combination of procaine, anti-inflammatory medications, vitamins, minerals, and a mixture of ozone/oxygen gas is injected into joints or tissues that have been injured or have degenerated. When performed under ultrasound guidance, Prolozone therapy quickly reduces pain and inflammation while jump-starting the healing process.

Ultrasound Guided Dry Needling of the Patellar Tendon

Myofascial trigger points often contribute to patellar tendon pain. Dry needling is an outpatient procedure where non-medicated needles are inserted into the trigger point to evoke a twitch response, releasing the trigger point and immediately relieving pain. Ultrasound guidance eliminates the need for multiple insertions, reducing pain and discomfort for the patient.

In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
