Me Knee Hurts When I Run Or Squat... What's That About?

If your knee starts barking every time you go for a run or drop into a squat, you’ve probably already Googled it, found ten different possible diagnoses, and closed the tab more confused than when you started. Here’s the short version: in active adults, knee pain during loaded movement is rarely about a joint that’s “wearing out.” It’s almost always about how load is moving through the joint — and that’s fixable. The Usual Suspects A few patterns show up again and again in our clinic: Patellar tracking issues. Your kneecap is supposed to glide smoothly in a groove at the front of the femur. When the muscles around your hip and thigh aren’t pulling evenly, the kneecap can drift slightly off-track, creating friction and pain — especially on stairs, squats, and downhill running. Quad-to-glute imbalance. Many active adults have become quad dominant over years of running, cycling, or sitting at a desk. When the glutes aren’t doing their share of the work, the knee absorbs forces it wasn’t built to handle alone. Overuse without adequate recovery. Sometimes it’s simpler than a mechanical fault — training volume has outpaced tissue capacity. The tendons around the knee (especially the patellar tendon) can become irritated when load increases faster than they can adapt. Why “Just Rest It” Usually Backfires The instinct to stop moving entirely and wait for pain to disappear is understandable, but it often makes things worse for active adults. Tendons and joints get stronger through appropriate loading, not through avoidance. Complete rest can lead to deconditioning, which means when you do return to running or squatting, your knee is even less prepared to handle it — and the cycle repeats. This doesn’t mean push through sharp pain. It means the goal isn’t zero movement — it’s smart movement. How We Actually Diagnose It Rather than guessing from a list of symptoms, we start with a movement assessment: how you squat, how you land, how your hip and ankle move relative to your knee. This tells us whether the issue is really coming from the knee itself, or whether the knee is just the messenger for a hip or ankle mobility problem upstream. From there, we can usually tell within one visit whether you’re dealing with a tracking issue, a tendon overload issue, or something that needs imaging to rule out a structural problem. What Treatment Looks Like Once we know the root cause, treatment typically combines: Manual care to address joint mechanics and reduce irritation Targeted strength work for the glutes, hips, and often the often neglected muscles around the ankle A progressive loading plan that lets you keep training — modified, not eliminated — while your knee rebuilds capacity Most people are surprised that “fixing” the problem doesn’t mean stopping the activity that caused it. It means training smarter around it while the underlying issue resolves. The Bottom Line Knee pain during running or squatting is a signal, not a life sentence. The goal at Hybrid isn’t just to make the pain go away — it’s to figure out why it started so it doesn’t come back the moment you resume training.
