Why does my knee hurt when I go up and down stairs?
Stairs shouldn’t be something you dread. If you wince every time you climb or descend a flight, your knee is telling you something worth listening to — and in most cases, it’s something that can be significantly improved with the right approach.
Common causes of knee pain on stairs
Patellofemoral pain syndrome
This is one of the most common causes of stair-related knee pain, particularly in active people and those who sit for long periods. It occurs when the kneecap doesn’t track smoothly in its groove, creating friction and irritation under the patella. The pain is typically felt at the front of the knee and is worse going downstairs than up.
Osteoarthritis
Cartilage breakdown in the knee joint is very common in adults over 50, and stairs are one of the first activities to become painful — because stair climbing loads the knee joint at up to 3–4 times your body weight. Morning stiffness that eases with movement is a hallmark sign.
IT band syndrome
The iliotibial band is a thick band of connective tissue running down the outside of your thigh to your knee. When it becomes tight or overloaded — common in runners and cyclists — it causes a sharp or burning pain on the outer side of the knee, particularly on descent.
Patellar tendinopathy
Also called “jumper’s knee,” this involves degeneration of the tendon connecting your kneecap to your shin bone. It produces pain just below the kneecap and is aggravated by loading activities like stairs, squatting, and jumping. It’s common in athletes but can affect anyone.
Weak glutes and quadriceps
The muscles around your hip and thigh play a major role in controlling how your knee moves on stairs. When they’re weak, the knee is forced to absorb more load than it should, and the kneecap can track poorly — leading to pain that often responds dramatically well to targeted strengthening.
What you can do about it
The approach depends on the cause, but these steps are a solid starting point for most stair-related knee pain:
- Strengthen your glutes and quads — these are the muscles most responsible for protecting your knee on stairs, and targeted exercise is the most evidence-based treatment available.
- Lead with your stronger leg going up stairs and your affected leg going down, to reduce load on the painful knee while you recover.
- Avoid prolonged sitting with your knees bent if it aggravates symptoms — take regular standing breaks throughout the day.
- If you’re carrying extra weight, even a small reduction can meaningfully decrease the load on your knee joints during stair use.
- Get a proper assessment — the cause of stair pain matters enormously for treatment. Patellofemoral pain needs a different approach to arthritis or tendinopathy.
When to seek help sooner
See a health professional promptly if you notice any of the following:
- Significant swelling around the knee joint
- Your knee gives way or feels unstable on stairs
- A locking sensation where the knee won’t straighten fully
- Pain that is severe or came on after a fall or impact
- Knee pain that is progressively worsening despite rest
