Summary: Patellar tendinitis, or jumper's knee, is irritation of the tendon that connects the kneecap to the shin, usually from repetitive jumping or running. It causes pain just below the kneecap. Most cases improve with non-surgical care such as activity changes, targeted physical therapy, and, in some cases, shockwave therapy or regenerative treatment.

That nagging pain just below the kneecap that flares when you jump, squat, or climb stairs has a name. Patellar tendinitis, better known as jumper's knee, is a common overuse problem in active people, and it rarely needs surgery when it is caught and managed well.
This article explains what jumper's knee is, why it develops, how to recognize it, and the non-surgical options available in Palm Beach County. Understanding the condition helps you protect the tendon and get back to the activities you enjoy.
What Is Patellar Tendinitis (Jumper's Knee)?
Patellar tendinitis is irritation and small scale breakdown of the patellar tendon, the strong band that connects the kneecap to the top of the shin. It develops when the tendon is loaded faster than it can recover, which is why it is common in jumping and running sports.
The pain sits at the front of the knee, right below the kneecap, and tends to worsen with activity. Because it is a tendon overuse problem rather than a joint problem, the knee itself usually feels stable even when the tendon is sore.
What Causes Patellar Tendinitis and Who Is at Risk?
Jumper's knee is an overuse injury. It develops from repetitive stress on the tendon, most often from frequent jumping, sprinting, or rapid changes in training load. The tendon does not get enough time to adapt, and irritation builds up.
Risk is higher in sports like basketball, volleyball, and pickleball, and in people who ramp up training quickly. Tight or weak thigh muscles, hard playing surfaces, and sudden increases in intensity can all contribute. Active adults in South Florida who play year round are common candidates.
Symptoms: How to Recognize Jumper's Knee
The hallmark symptom is pain and tenderness just below the kneecap, especially with jumping, squatting, kneeling, or going up and down stairs. Early on, the pain may appear only after activity, then progress to hurting during activity if the tendon is not given a chance to recover.
Some people also notice stiffness in the morning or after sitting, and a tender spot they can press on at the base of the kneecap. If pain lingers or worsens, it is worth an evaluation before it limits your training further.
Non-Surgical Treatment Options in Palm Beach
Most cases of patellar tendinitis improve without surgery. Care starts with adjusting activity to calm the tendon, followed by a structured physical therapy program that emphasizes progressive strengthening, which is the core of tendon recovery, along with addressing tight or weak supporting muscles.
When symptoms are stubborn, an orthopedist may add options such as shockwave therapy for chronic tendon irritation, and in select cases regenerative treatment like platelet rich plasma (PRP) may be discussed to support tendon healing, though results vary from patient to patient and are not guaranteed. You can see how PRP is used in sports medicine and review our approach to shockwave therapy in orthopedics.
How an Orthopedist Diagnoses Patellar Tendinitis
Diagnosis is usually clinical. An orthopedist reviews your activity history and examines the knee, pressing along the patellar tendon to locate the tender spot and testing how the knee responds to load. That pattern often points clearly to the tendon.
Imaging can confirm the diagnosis and rule out other causes when needed. In-office ultrasound shows the tendon in real time and can reveal areas of irritation, which helps guide treatment. Explore our sports medicine care for how these conditions are managed.
When to See an Orthopedist for Knee Pain
See an orthopedist if knee pain below the kneecap lasts more than a couple of weeks, worsens with activity, or starts limiting your training or daily movement. Early care helps prevent a minor tendon irritation from becoming a stubborn, long lasting problem.
At Tyrance Orthopedics & Sports Medicine, knee and tendon problems are evaluated with an emphasis on non-surgical, minimally invasive care first. The goal is to protect the tendon and return you to sport safely rather than sidelining you longer than necessary.
Frequently Asked Questions
How long does patellar tendinitis take to heal?
Recovery varies with severity and how consistently the tendon is rested and rehabilitated. Mild cases can settle in a few weeks, while stubborn cases take longer and need a structured strengthening program. Early treatment generally shortens the timeline.
Can I keep playing sports with jumper's knee?
Continuing at full intensity often makes patellar tendinitis worse. Many people can stay active with modified training while the tendon recovers, but the right adjustments depend on severity. An orthopedist can help you find a level of activity that supports healing.
What is the difference between patellar tendinitis and a knee joint problem?
Patellar tendinitis affects the tendon below the kneecap and is an overuse issue, while joint problems involve the cartilage or structures inside the knee. The location of pain and how it behaves with activity help tell them apart, and an exam confirms it.
Does patellar tendinitis require surgery?
Rarely. The large majority of cases improve with non-surgical care, especially progressive strengthening. Surgery is considered only in a small number of cases that do not respond to a thorough course of conservative treatment over time.
Can PRP help jumper's knee?
Platelet rich plasma is sometimes discussed as an option to support tendon healing in select cases of patellar tendinitis. Whether it is appropriate depends on your situation, and results vary and are not guaranteed. An evaluation is the most reliable way to decide.
Nutritional support for recovery
As part of a non-surgical or recovery plan, some patients ask about supplements that may support joint comfort and healing. Avastar OptimaLife, the affiliated nutraceutical line founded by Dr. Tyrance, includes options such as JointCare Tendon & Ligament and CurcuMax Pro. These supplements may support, but do not replace, medical treatment—ask Dr. Tyrance what fits your plan.
