That persistent, achy pain around the front of the knee, especially after a run, has a name: runner's knee. It's one of the most frustrating overuse injuries out there — you feel fine warming up, and somewhere around mile two that familiar throb creeps in. The good news is it's very treatable, and you don't have to bench yourself indefinitely to recover.
What runner's knee actually is
"Runner's knee" is the common name for patellofemoral pain syndrome (PFPS) — pain around or behind the kneecap that happens when the cartilage under the patella gets irritated because the kneecap isn't tracking smoothly. Despite the name, hikers, cyclists, and anyone on their feet for long hours can develop it too; runners are just especially prone to it given how many flexion-extension cycles a single run puts the knee through.
Typical symptoms: a dull ache at the front of the kneecap, pain that worsens with running, squatting, or stairs, a grinding or clicking sensation, and mild swelling or stiffness after activity.
What's actually causing it
A few common culprits, often stacked together: ramping up mileage faster than your joints can adapt; weak hips and glutes, which let the thigh collapse inward with each stride and pull the kneecap off-course; movement habits like overstriding or heavy heel-striking; tightness in the IT band, hip flexors, or quads pulling the patella out of alignment; and worn-out or mismatched footwear subtly altering your gait over thousands of steps.
Making sure it's actually runner's knee
Not every knee issue in a runner is PFPS, and the right diagnosis changes the treatment. IT band syndrome causes sharp, burning pain on the outer knee at a predictable point in the run. Patellar tendinopathy shows up just below the kneecap, often worse the next morning. Meniscus irritation involves catching or locking. A thorough assessment before treatment matters, since the right care for one of these looks different from the right care for another.
How chiropractic care helps
The knee doesn't work in isolation — hip mechanics, pelvic alignment, and ankle function all affect what happens at the knee with every stride. Treatment typically combines joint work on the hip, SI joint, or ankle to take pressure off the kneecap; soft-tissue therapy on the IT band, quads, hamstrings, and calves; corrective strengthening for the hip abductors, glutes, and the inner quad muscle that stabilizes the kneecap; gait analysis to identify what's driving the pain; and guidance on how to modify training safely rather than stopping entirely.
When to get it looked at
If knee pain has lasted more than two weeks, is getting worse, or is starting to affect daily activities beyond running, earlier care leads to better, faster outcomes.
Keeping it from coming back
A few habits that make a real difference: increase weekly mileage gradually (no more than about 10% at a time), build hip and glute strength into regular training rather than only after something hurts, replace running shoes every 300–500 miles, warm up dynamically before runs, and address soreness early before it becomes chronic.
