Jumper's knee: tendon pain below the kneecap
Patellar tendinitis (jumper's knee) is overuse inflammation of the tendon connecting the kneecap to the shinbone, common in athletes who jump or run. Same-day or next-week evaluations across eight LA-area offices.

Key takeaways
Patellar tendinitis (jumper's knee) is overuse inflammation of the tendon connecting the kneecap to the shinbone, common in athletes who jump or run. Symptoms can develop gradually or after a specific injury, so early evaluation matters when function starts to decline.
Most patients with patellar tendinitis improve with conservative care: cutting back on jumping and running for a while, a physical therapy program that gradually strengthens and loads the tendon, stretching, and a patellar strap when it helps. Steroid injections into this tendon are generally avoided because they can weaken it. Surgery is uncommon and is reserved for cases that have not improved after months of dedicated rehabilitation.
Below, we walk through the anatomy involved, the symptoms and causes we most often see, how we diagnose patellar tendinitis, and the full range of treatment options, from the simplest to the most involved.
This is a pain you feel just below your patella (the bone we commonly call the "kneecap"). It's an injury to your patellar tendon, which connects the bottom of the kneecap to the shinbone.

The knee is the body's largest hinge joint: it bears your weight, absorbs impact, and lets you walk, run, and pivot. Cartilage and meniscus cushion the joint, while ligaments (ACL, PCL, MCL, LCL) keep it stable. Most knee problems come from wear of those cushioning surfaces or from twisting injuries that damage a ligament or meniscus.
You want answers, fast, and we're built to give them. Most patients leave their first LAOSS visit with a clear diagnosis and a written plan, not another referral chain.
Here's what your initial visit for patellar tendinitis typically looks like:
Schedule your evaluation at the LAOSS office nearest you.
Once we've confirmed the diagnosis, the next step is matching the right treatment to your situation. We start with the least-invasive option that fits, and escalate only when it doesn't.
Non-surgical options designed to relieve pain, restore movement, and avoid the OR when possible.
Surgery is uncommon and is considered only when months of dedicated rehabilitation have not relieved symptoms.
Knee care is highly technique-dependent. Volume, training, and judgment together determine the outcome you actually feel six months later.
Our knee specialists move stepwise: start with the least-invasive option that fits your situation, escalate only when it doesn't.
If most of these match your situation, an evaluation with a knee specialist is the next step.
These signs typically point toward an in-person evaluation with a knee specialist.
Your first visit is built to give you an answer the same day, not just another referral.
ImportantSeek urgent evaluation for sudden severe pain, numbness, progressive weakness, or any sign of infection (fever, increasing redness or swelling).
Recovery is rarely a straight line, but a clear plan with measurable milestones makes the path predictable.
In the first two weeks we focus on protecting the knee, calming inflammation, and restoring basic motion.
Targeted physical therapy rebuilds strength, mobility, and confidence in the knee.
Once function is restored, the focus shifts to keeping you there, and catching any recurrence early.
We talk through the risks and benefits with every patient. Informed consent is a conversation, not a form.
Every orthopedic intervention carries a small set of standard risks. We screen, prepare, and monitor for these on every patient.
Some risks are tied to the structures we're treating in the knee. We discuss these in detail at your visit so you can weigh them against the benefits.
At LAOSS, our knee specialists are board-certified and treat these problems every day. From minimally invasive arthroscopic techniques to joint replacement and arthritis management, our physicians bring decades of experience to every case. We have cared for Los Angeles patients since 2007, with one goal for each: less pain, better movement, and a return to the activities you love.
