Anterior knee pain is one of the most common complaints I see, but it is also one of the most commonly dismissed. Many patients are told they have “runner’s knee” or “patellofemoral pain syndrome” and sent away with a generic prescription: do more physical therapy. Some have followed that advice for years with little or no improvement.

In this video, my husband, Dr. Andreas Gomoll, and I explain why runner’s knee is not a real diagnosis and walk through the most common true causes of pain in the front of the knee.

Transcript

So, one of my pet peeves is when patients are told by another doctor that they have runner's knee or patellofemoral pain syndrome because Chondromalacia patella is also sort of a Because at least the first two aren't very specific diagnoses and since there's specific things that can cause pain in the front of the knee, it's much more helpful if you actually diagnose exactly what's wrong because that can help determine how to treat it. Yeah, and a lot of surgeons at least dismiss patients who come in with pain in the front of the knee and and they just tag them based on x-rays alone or maybe just a story with kind of these terms and then essentially say, "No, go away, do PT, do more PT." And some patients have tried that for years without improvement. So, starting with the simple, there's patellar tendonitis. It's usually in runners or jumpers and it can be treated with physical a specific type of targeted physical therapy, platelet-rich plasma, and even shockwave. And then there's cartilage pathology. Yeah, so sometimes there's a true structural damage inside the knee like cartilage pathology and that again is a completely different type of treatment. So, type of surgical treatment oftentimes. And there are injections sometimes. So, lots of different options, but you need to know why exactly you're hurting. And and then there's patients who have instability and so if they have patellar instability causing their anterior knee pain, then by and large that needs to be stabilized and and that's something that we can do pretty pretty well and with pretty good outcomes. Yeah, but like we said, we don't like to dismiss people just based on their story.

Vague Labels Aren’t Real Diagnoses

The problem is that these labels are not specific diagnoses. There are several distinct causes of pain in the front of the knee, and identifying the true source of the problem is the key to choosing the right treatment. When we stop at a vague term, we risk missing targeted options that could actually help you get back to the activities you love.

Patellar Tendonitis: A Common but Treatable Cause

One common cause is patellar tendonitis, often seen in runners and jumpers. This is typically treated with a specific, targeted physical therapy program, and in some cases advanced options like platelet-rich plasma (PRP) injections or shockwave therapy. When the tendon is the issue, these focused treatments are much more effective than a one‑size‑fits‑all PT approach.

Cartilage Damage: When the Joint Surface Is Injured

Another important category is cartilage pathology—true structural damage inside the knee. Cartilage injuries usually require a completely different approach, often including surgical treatment designed to address the damaged area. Treating cartilage damage like simple overuse pain means you may never get the improvement you’re looking for.

Patellar Instability: When the Kneecap Won’t Stay in Place

Some patients have patellar instability as the main driver of their anterior knee pain. In these cases, the kneecap does not track or stay in place properly, and by and large that instability needs to be stabilized. Fortunately, we can often correct this with well‑established procedures and see very good outcomes.

Why You Shouldn’t Settle for a Runner’s Knee Diagnosis

The takeaway is that persistent anterior knee pain deserves more than a quick label and a dismissal. With a careful evaluation and an accurate diagnosis, we can match your treatment to the true underlying problem—whether that means targeted PT, injections, biologics, shockwave, or surgery. You should not be told to simply live with it when there are specific, effective options available.

If you’re dealing with ongoing pain in the front of your knee and haven’t gotten clear answers, consider scheduling a consultation so we can determine what’s really causing your symptoms and discuss the best treatment options for you.
