Regenerative, orthobiologic care for patellofemoral pain and chondromalacia — for kneecap pain that hasn't settled with rest and rehab alone.
Your kneecap — the patella — glides up and down a shallow groove at the end of the thigh bone every time you bend and straighten the knee. The underside of the kneecap is lined with cartilage, in fact some of the thickest cartilage anywhere in the body.
Patellofemoral pain is pain around or behind the kneecap, usually because the kneecap is not tracking smoothly in its groove — which overloads the cartilage and the soft tissues around it. Chondromalacia is the next chapter of the same story: actual softening and breakdown of that kneecap cartilage.
It is often brushed off as "runner's knee" — minor, temporary, something that will quiet down on its own. For a great many people, it does not.
One thing to say plainly up front: the evidence-based first step for kneecap pain is a good rehabilitation program — strengthening the hip and thigh, improving how the kneecap tracks. That genuinely helps many people, and it is the right place to start. This page is about the next step — when the cartilage itself is involved, and a real rehab effort has not been enough.
Think of the kneecap like a train and its groove like the track. When the train rides centered, it glides. When it drifts toward one edge, the wheel grinds that rail — and over thousands of trips, the rail wears. Kneecap pain is rarely about a "bad" kneecap; it is about how the kneecap is riding its track, and the wear that follows.
Patellofemoral pain has a recognizable signature — and it behaves differently from a meniscus or joint-line problem. If several of these fit you, the kneecap is likely involved.
Hard to pin down with one finger — the pain feels like it comes from under or around the kneecap rather than a single spot.
Descending loads the kneecap hardest. For many patients, heading down a flight of stairs is the move they dread most.
A deep ache after a long drive or a movie — the classic "theater sign" — that eases once you stand up and move around.
Anything that presses the kneecap firmly into its groove — squatting down, kneeling, lunging — tends to flare it.
A sense of grating as the knee bends — sometimes something you can feel with a hand resting on the kneecap.
The kneecap visibly slipping out of place (dislocating), the knee giving way hard, or a sudden large swelling after an injury.
Watch for: these need prompt, in-person evaluation rather than waiting it out."Runner's knee" sounds harmless — a nuisance that rest will fix. The evidence tells a different story.
Patellofemoral pain is one of the most common knee complaints there is, affecting roughly a quarter of the general population and more than a third of athletes. And it is not self-limiting: across long-term studies, more than half of people still have an unfavorable outcome 5 to 20 years later, and 70–90% report that their symptoms return.
That does not mean your knee is doomed. It means kneecap pain is worth a real diagnosis and a real plan — not a shrug and "rest it." When pain has lasted months, kept returning, or reached the point of chondromalacia, it deserves a proper look.
That look takes in the whole picture: how the kneecap tracks, the strength of the muscles that steer it, and — once cartilage softening has set in — the state of the cartilage itself. That is what Dr. Booth examines with you before recommending anything.
"'Runner's knee' is dismissive. Half of these knees still hurt years later."
— Orthobiogen care philosophy
The cartilage behind the kneecap is thick and durable, but it is sensitive to how it is loaded. Calm the irritation and address the load, and the joint can settle.
Strengthening the hip and thigh and retraining how the kneecap tracks is genuine first-line care and helps many people. Regenerative treatment is not a replacement for that work — it complements it when the cartilage itself is involved.
A small sample of your own blood is concentrated for its platelets and growth factors and placed in and around the joint to calm inflammation and support a healthier environment for the kneecap cartilage.
The cartilage, the way the kneecap tracks, and the muscles that steer it are all part of one plan — addressed together, not one in isolation.
When a real rehab effort has not settled kneecap pain, patients are usually offered a cortisone shot or, eventually, surgery. Here is how an orthobiologic approach differs.
| Cortisone Injections | Patellofemoral Surgery | Orthobiogen |
|---|---|---|
| ✗ Quiets inflammation for a few months at a time | ✗ Cuts or realigns soft tissue or bone to change how the kneecap tracks | ✓ Calms the joint and supports the kneecap cartilage with your own biologics |
| ✗ Does nothing for the softened cartilage | ✗ Does not restore worn or softened cartilage | ✓ Aims to support the cartilage behind the kneecap |
| ✗ Corticosteroid — a medication, not a repair | ✗ A release or realignment, with limited evidence for isolated kneecap pain | ✓ Platelets or marrow drawn from your own body |
| ✗ Wears off in months; doses are capped per year | ✗ Permanent and irreversible | ✓ Repeatable, with nothing cut or removed |
| ✗ Often a brief visit with little imaging review | ✗ Operating room, anesthesia, and months of rehab | ✓ Outpatient, with your imaging walked through with you |
| ✗ "Try a shot and see," with little candidacy screening | ✗ A major step for a problem that often responds to less | ✓ An honest answer on whether you are a candidate, first |
Usually not. The evidence-based first step for kneecap pain is a good rehabilitation program — strengthening the hip and thigh and improving how the kneecap tracks — and that genuinely helps many people. Surgery cuts or realigns soft tissue or bone and has limited evidence for isolated kneecap pain, so it is a major step for a problem that often responds to less.
“Runner's knee” sounds harmless, but the evidence tells a different story. Patellofemoral pain is one of the most common knee complaints there is, and it is not self-limiting — across long-term studies, more than half of people still have an unfavorable outcome 5 to 20 years later, and 70 to 90% report that their symptoms return. It deserves a real diagnosis and a real plan, not a shrug and “rest it.”
A cortisone injection quiets inflammation for a few months at a time, but it is a corticosteroid medication, not a repair, and it does nothing for the softened cartilage. Regenerative care works differently — it uses your own platelets to calm the joint and support the cartilage behind the kneecap, alongside the rehab that strengthens the muscles steering it.
Generally no. Regenerative orthobiologic treatment is typically not covered by insurance. If you move forward, the costs are discussed openly and in full before anything is scheduled — no surprises.
Start with a free 15-minute introductory telemedical consult — a no-pressure conversation about your history and any imaging you already have, with a candid read on whether regenerative care is a reasonable fit for your knee. The fastest way to begin is the secure online intake form, and Dr. Booth's team follows up with you directly.
Patellofemoral pain is far from rare. A systematic review pooling prevalence studies found it affects a sizable share of the population — and an even larger share of younger and more active people.

The first step is a complimentary, 15-minute introductory telemedical consult. It is a no-pressure conversation to hear your story, look at what you have already tried, and give you a candid sense of whether regenerative care is a reasonable fit for your knee.
Please note: complimentary telemedical consults have limited availability because of Dr. Booth's clinical schedule. If a slot is not immediately open, we appreciate your patience — or you are welcome to request a standard in-person appointment instead, which can often be arranged sooner.
