Pain in the kneecap can be a really frustrating issue, and can happen with almost any activity. This includes running, squatting, walking (especially downhill), and stairs to name a few. Many people notice knee pain when walking, knee pain when squatting, or knee pain when running, particularly downhill or on stairs. Some even describe IT band knee pain or symptoms consistent with patellofemoral pain syndrome. As Physical Therapists, there are quite a few issues we find result in kneecap pain. Here are some of the main issues we find during our evaluation.
Your kneecap is technically a floating structure and is pulled in each direction by muscles, ligaments, and connective tissue. When your femur or thigh bone rotates, or moves, that doesn't necessarily mean your kneecap moves with it
Your hip muscles, like your buttocks and gluteus medius, control your femur and keep it from collapsing inward. When your hips are weak, or tire easily, your femur tends to collapse inward, and rotate inward. This can lead your knee cap being pulled toward the outside of the knee and unequal distribution of pressure on the patella. This is a classic pattern of weak hips causing knee pain.
Like we've explained in our post about the knee anatomy, your kneecap connects to your quadriceps. The more your quadriceps pull on your kneecap, the more the pressure on that joint. Makes sense, right?
Well since your calf and hamstrings pull the opposite way of your quadriceps, if they are tight, they make your quadriceps work harder. This is why regular stretching, especially if you don't have great flexibility, can help your knee pain!
Remember when we told you the kneecap is pulled in different directions? Well, what we've found with a lot of people with patellar pain, is the kneecap glides more lateral, or to the outside of the knee. This can happen from all of the lateral structures pulling on the knee cap becoming tight. Your IT band can be a main culprit of this as it attaches to multiple different muscles and pulling the retinaculum of the kneecap. Targeted patellar tracking exercises can help guide the kneecap centrally and reduce irritation.
Yes. An excellent physical therapist will measure all of the things listed below and determine where your greatest deficit lies. There are other, less common ways kneecap pain develops, which will always be considered in your plan of care. A course of physical therapy for knee cap pain typically blends patellar tracking exercises with hip and quadriceps strengthening, flexibility work, and activity modification.

Question: Why does my kneecap hurt during activities like running, squatting, walking downhill, or using stairs?
Short answer: These activities load the kneecap and can expose imbalances around the knee. If your hips are weak or certain muscles are tight, your thigh bone may collapse or rotate inward, and the kneecap can be pulled off-center. That uneven pull increases pressure on parts of the patella and can lead to pain, especially with higher-demand tasks like downhill walking or stairs.
Question: How do weak hips contribute to kneecap pain?
Short answer: Your kneecap is a “floating” structure influenced by surrounding muscles and tissues. Strong hip muscles—especially the gluteus medius and buttocks—help control the femur’s position. When hips are weak or fatigue easily, the femur tends to collapse and rotate inward. This can pull the kneecap toward the outside of the knee, creating unequal pressure on the patella and resulting in pain.
Question: What role does flexibility play in kneecap pain?
Short answer: The quadriceps attach to the kneecap, so increased quadriceps pull raises pressure on the joint. Tight calves and hamstrings oppose the quads and can make them work harder, further increasing patellar pressure. Regular stretching—especially if you’re not very flexible—can reduce this extra pull and help ease knee pain.
Question: What is patellar tracking, and how can the IT band affect it?
Short answer: Patellar tracking describes how the kneecap glides as your knee moves. Many people with patellar pain have a kneecap that glides more laterally (toward the outside). Tight lateral structures—often including the IT band, which influences tissues that guide the kneecap—can pull it outward. Targeted patellar tracking exercises aim to guide the kneecap more centrally to reduce irritation.
Question: Can physical therapy help, and what might a plan include?
Short answer: Yes. A skilled physical therapist will assess hip strength, flexibility, patellar tracking, and other contributing factors to find your main deficits. A typical plan blends patellar tracking exercises, hip and quadriceps strengthening, flexibility work, and activity modification. Less common causes are also considered to tailor care. If you have kneecap pain with walking, running, squatting, or stairs, contacting a PT clinic can help you reduce pain and reach your goals.
