Symptoms
How it tends to show up
Pain and tenderness right below the kneecap; pain with jumping, landing, squatting, or stairs; stiffness at the front of the knee after sitting or in the morning; an ache that warms up with activity but returns afterward; pain that worsens with heavy or repeated loading.
How Common
You're not alone in this
Jumper's knee is one of the most common overuse knee problems in active people — and it's far more widespread than most patients realize. Among elite jumping athletes it's strikingly common: studies put it near 45% in elite volleyball players, and roughly 14% of recreational jumping athletes report symptoms at any given time. It clusters heavily in volleyball and basketball, but I see plenty of it in CrossFit, running, surfing, and even folks whose only "sport" is hard concrete floors at work. Why does that matter to you? Because this is a well-understood, well-mapped condition — not a mystery — and the large majority of people improve with the right loading plan.
The Root
Why it keeps coming back
Patellar tendinopathy is an overload problem. When the muscles of the hip, thigh, and calf don't share landing and squatting forces well, the patellar tendon carries more than its share and stays overloaded. Rest settles it, but returning to sport without changing the load pattern brings it right back — the tendon was never the only issue.
Who Gets It
Common risk factors
- Jumping and cutting sports (volleyball, basketball)
- Sudden spikes in training volume or frequency
- Hard playing surfaces like concrete
- Tight quadriceps or hamstrings
- Weak or 'switched-off' glutes and calves up the chain
- Higher body weight or BMI
- Leg-length differences or flat/high arches
- Being male and in the teens-to-30s age range
Look-Alikes
Is it Jumper's Knee (Patellar Tendinitis), or something else?
Several other problems can mimic this, and they're managed differently — so part of the assessment is telling them apart.
Wondering if this is what's going on — and what care would look like?
Book an Assessment →The Approach
How Dr. Imada approaches it
Using Advanced Muscle Integration Technique (AMIT), I find which muscles up and down the chain have switched off and restore them so the tendon isn't overloaded. Chiropractic care and Foundation Training rebuild balanced lower-limb strength, and we progress tendon loading carefully. This reflects what I see work for stubborn tendon pain — offered as clinical insight, not a promise.
Getting Answers
How it's assessed
Clinically, jumper's knee is usually clear from your story and a hands-on exam — you'll typically point to one tender spot right at the bottom tip of the kneecap, and the pain shows up when the knee straightens under load (jumping, squatting, stairs). I confirm it with simple tests: tenderness that eases when the knee is bent to 90 degrees, and pain reproduced with loaded knee extension. Here's the important reframe most people miss — despite the old name "tendinitis," this is not really an inflammation problem. It's a degenerative overload of the tendon, where the collagen has started to disorganize from repeated stress without enough recovery. My whole-chain assessment then looks for why the tendon got overloaded in the first place — hips, calves, and ankle mechanics that quietly hand extra work to that one tendon. Imaging like ultrasound or MRI is supportive but rarely required to start, and if anything in your exam points to a tear or another problem, that's something I'd refer out for proper evaluation.
Your Visit
What to expect
An assessment of the hip–knee–ankle chain; an explanation of why the tendon stays overloaded; hands-on care to restore muscle function; and a graded loading plan so the tendon can rebuild capacity for your sport.
At Home
What you can do yourself
- Modify load — cut the jumping and deep squatting, don't fully rest
- Keep moving with low-impact activity to stay conditioned
- Ice briefly for soreness, but not right before activity
- Try a patellar strap to offload the tendon
- Gently work on quad and hamstring flexibility
- Avoid 'pushing through' sharp tendon pain
These steps calm symptoms and protect the tendon day to day, but they work best alongside a progressive loading plan that rebuilds the tendon and addresses why it got overloaded.
Outlook
Recovery & realistic timelines
Here's the honest timeline: this tendon heals slowly because it's a remodeling job, not a quick inflammation that settles in a week. Mild cases often turn the corner in roughly three weeks, while more stubborn or chronic cases commonly take three to six months, and the most severe can run 6 to 12 months. The encouraging part is that about 90% of people improve with non-surgical care, and progressive loading — done patiently — is what consistently helps. My aim is to shorten that arc by loading the tendon correctly and unloading the chain above it, rather than just resting and hoping. Surgery is reserved for the small number who don't respond to six months of good rehab, and that's a decision made alongside an orthopedic surgeon.
Staying Ahead
Keeping it from coming back
- Ramp training volume up gradually, not in sudden spikes
- Build glute, calf, and quad strength up the chain
- Warm up and cool down around hard sessions
- Take real rest days and off-seasons
- Address tight quads and hamstrings early
- Don't train through tendon pain

FAQ
Common questions
Is jumper's knee actually 'tendinitis'?
Not in the classic sense. Despite the name, the research is clear that it's usually a degenerative overload of the tendon rather than active inflammation — which is why simply resting or taking anti-inflammatories often isn't enough.
Should I rest completely until it stops hurting?
Usually not. Total rest tends to weaken the tendon further. Relative rest — backing off the aggravating loads while keeping the tendon gently working — is what the evidence supports.
Why do loading exercises help a painful tendon?
Controlled, progressive loading stimulates the tendon to remodel and reorganize its collagen, which is exactly what a degenerative tendon needs. It's one of the most consistently effective treatments in the literature.
Do I need an MRI or ultrasound?
Often no. This is typically a clinical diagnosis from your history and exam. Imaging is helpful when the picture is unclear or recovery stalls, but it rarely changes how we start.
Are cortisone shots a good idea?
Generally I steer away from them here. They can ease pain short-term but are linked to tendon weakening and even rupture, so they're not a first-line answer for this condition. That's a discussion to have with the physician offering them.
Will it come back?
It can, if the underlying overload pattern isn't addressed — which is exactly why I look up the chain at the hips and calves, not just at the sore spot below your kneecap.
Can I keep playing my sport?
Sometimes, with modified load and a strap — but in-season loading drills can backfire. I'd rather build a plan that protects your season and your tendon, which is something we'd map out together.
When should I worry it's something more serious?
A sudden pop, marked weakness, or being unable to straighten your knee can signal a tendon tear and needs prompt evaluation — that's something I'd refer to a physician or surgeon right away, not treat with chiropractic alone.
