Knee Pain and Hip Weakness: Is There a Link?

Knee pain and hip weakness often show up together, and many people are surprised by that. You feel the ache at the front of the knee, yet the hip may be part of the story. This guide looks at how the two connect and what you can notice, ask about and try.

Why knee pain and hip weakness can go together

Your thigh bone sits in the hip and meets the knee lower down. The muscles around the hip, including the glutes, help hold the thigh steady when you stand on one leg. That happens with every step.

If those muscles tire quickly, the thigh can turn in a little and the knee can drift toward the middle. Then the front of the knee, around the kneecap, takes more load than it likes. This is often called patellofemoral pain, which simply means pain where the kneecap meets the thigh bone.

Research links weaker hip muscles with this kind of knee pain, and clinical guidelines include hip work in the care plan. It is not a simple one way street, though. Pain can make you use the hip less, so weakness may be part cause and part result.

Knee problems are very common. Among joints hit by osteoarthritis, the knee leads, with roughly 365 million people affected worldwide (WHO, 2023). Not every sore knee is arthritis, but it shows how many people live with knee trouble. How you walk matters too, and the Feldypedia article on changes in how we walk explains why.

Signs it may be a hip and knee pattern

None of these prove anything, but they are worth noticing:

• Your knee drifts inward when you stand on one leg or climb stairs.
• The pain shows up on stairs, when squatting, or after sitting for a long time.
• One leg feels less steady than the other when you stand on it.
• Your hips feel tired or shaky before your knees do.

Our guide to going down stairs looks at one of the moments where this tends to show. If the outer hip is the sore place, glute med pain is a helpful companion read.

What tends to help

A plan guided by a physiotherapist. Strengthening is a real part of care for this kind of pain. A physiotherapist can look at how you move, choose what suits you, and show you how to do it. This page cannot replace that.

Clearer sensing of how your leg organises. Strength is only part of the picture. How your pelvis, hip, knee and foot work together matters too. Slow, attention led movement, such as the Feldenkrais Method®, invites you to feel this for yourself. Nothing is forced and nothing is held. You simply notice more, and the way you move often follows.

To practise sensing your knee, try the knee proprioception exercises. The page on patellofemoral pain exercises looks at the kneecap more closely. Feldy offers short audio lessons in this style that you follow at home, and many people use them alongside their physiotherapy.

When knee pain is not about the hip

Sometimes the hip is not involved at all. Please see a clinician if you notice any of these:

• swelling in the knee
• the knee locking, or giving way after a twist
• a joint that looks red or feels hot
• pain that began after a fall or injury

These need a proper look before any new movement. Your doctor or physiotherapist is the right guide.

One thing to try noticing

The next time you rise from a chair, go slowly. Look down, or feel, where your knee points compared with your foot. Does it travel straight over the foot, or drift in? Just notice, without changing it. That one observation can tell you a lot.

Common Questions about knee pain and hip weakness (FAQ)

Can weak hips cause knee pain?

They can play a part, particularly in pain around the kneecap. Weaker hip muscles may let the knee drift inward on stairs or squats. Pain can also make you use the hip less, so the link often runs both ways.

Is it safe to exercise with knee pain, and who should get checked first?

Gentle, comfortable movement is usually fine for everyday knee aches. Get checked first if the knee swells, locks, gives way, feels hot, or hurts after an injury. If you are unsure, ask your doctor or physiotherapist before you begin.

How often should I work on hip strength for knee pain?

A physiotherapist can set a plan that fits you, including how often. For attention based movement, a few short sessions a week is a gentle place to start. Pain that grows afterwards is a sign to ease off and ask for advice.

How long until knee pain eases when the hips are involved?

It varies a lot. The NHS says knee pain that can be treated at home often starts to feel better within a few days, and advises seeing a GP if it is no better after a few weeks. A strength plan usually takes longer to show, so patience helps.

How is this different from just strengthening the knee?

Knee exercises focus on the muscles around the joint. A hip focused view asks how the whole leg shares the work, from pelvis to foot. Many people need both, and a physiotherapist can help you decide the mix.

When should I see a professional about knee pain?

See someone if the knee swells, locks, gives way after a twist, looks red or feels hot, or if pain follows an injury. Also book a visit if the pain is not improving after a few weeks. Early advice is always welcome.

What is the best exercise for hip weakness and knee pain?

There is no single best one. The most useful is the one a physiotherapist chooses for you and guides you through. Alongside that, slowly noticing how your knee lines up over your foot when you stand from a chair builds helpful awareness.

What should I avoid with knee pain?

Avoid pushing through sharp pain, deep squats or long runs that clearly make the knee worse, and sudden twisting on a planted foot. Comfort is a good guide. If a movement hurts, make it smaller or skip it for now.
