Are Your Hips Causing Your Knee Pain?
Knee pain is common and can significantly impact daily activities and overall well-being. Conditions such as arthritis, bursitis, ligament sprains, and muscle strains can all result in inflammation and discomfort. Understanding the connection between hip and knee pain is important – often our hips are the root of our knee problem.
Your hips can cause knee pain because they operate as a team—part of the same kinetic chain. If your hips are weak, stiff, or misaligned, your knees compensate by taking on extra stress, altering how you move, or feeling “referred” pain from shared nerves.
The relationship between your hips and knees typically breaks down into three main mechanisms:
1. Changed Biomechanics (The Compensation Effect)
Your hip is a flexible ball-and-socket joint built to rotate, while your knee is a hinge joint meant only for forward and backward movement. If your hips are tight, they lose their ability to rotate properly. When you walk or run, your knee is forced to twist and compensate.
Dynamic Valgus: Weak glutes or tight hip muscles cause your thigh to cave inward when you walk or squat. This places immense lateral and twisting stress on your knee cartilage, ligaments, and kneecap.
2. Muscle Imbalances
Many of the major muscles that control your knee start at your hip or pelvis. Tight hip flexors may pull your pelvis into a forward tilt, altering how your thigh muscles perform, and increasing pressure directly onto your kneecap (patellofemoral stress). Or when hip muscles (like the gluteus medius) are weak, the thick band of tissue running from your hip to the outside of your knee becomes tight and rubs painfully against the knee joint (iliotibial (IT) band syndrome.
3. Referred Nerve Pain
Sometimes, the knee pain you feel is entirely an illusion. Because the femoral, obturator, and sciatic nerves serve both the hip and the knee, an issue in your hips or pelvis can irritate a nerve that the brain incorrectly registers as coming from your knee.
When to Seek Help
Because treating the knee directly won’t fix the underlying hip dysfunction, identifying the root cause requires professional evaluation. Consulting a physiotherapist can help you pinpoint if weak glutes, tight hip flexors, or joint degeneration are contributing to your knee pain. The consultation may include a review of old injuries, strength testing, joint mobility, an assessment of balance & walking pattern, and a discussion of your daily routine. If your physiotherapist feels an x-ray should be ordered, they can request it directly and will review the results with you.
The goal is not just to calm symptoms, but to find out why the pain started and how to reduce the chance of it coming back.
Early Treatment is Better
Early advice can help prevent a minor issue from becoming a major problem. If your symptoms are affecting your daily routine, movement, sleep, or work, booking an appointment is a practical next step. Other signs you should get professional help include swelling, stiffness that lasts into the day, limping, pain that is getting worse, or symptoms that keep coming back each time you try to get active again.
