Knee Pain While Walking: When Should You Get Physiotherapy?

Common causes

Knee osteoarthritis. Aching during or after walking, stiffness after sitting and in the morning, more common after 45.

Patellofemoral pain. Pain around the kneecap, often worse on slopes and stairs.

Meniscus problems. Pain on the inside or outside of the knee, sometimes with catching or locking.

Tendon problems. Pain above or below the kneecap, often after increasing activity.

Referred pain. Hip problems can cause knee pain, so the hip is always checked.

When to get physiotherapy

• pain has lasted more than two to three weeks
• pain is limiting how far you can walk
• the knee swells after walking
• the knee catches, locks or gives way
• you're avoiding activities because of knee pain
• pain is getting worse over time

When to see a doctor urgently

Seek medical attention for a hot, red, swollen knee with fever, inability to bear weight after an injury, or sudden severe swelling.

What physiotherapy involves

Assessment identifies the cause, checks the hip and ankle, and looks at how you walk. Treatment usually includes strengthening, particularly the quadriceps and hip muscles, advice on activity and walking, and short-term pain relief options. Our knee exercises section shows the core exercises.

While you wait

• keep walking within comfort rather than stopping altogether
• split long walks into shorter ones
• choose flat routes
• wear supportive footwear
• try gentle exercises like straight leg raises

How your walking pattern matters

Physiotherapists usually watch you walk as part of the assessment, because small details change knee load. A long stride that lands the heel far in front of the body sends more force through the knee. A foot that rolls in markedly can twist the knee slightly with each step. A hip that drops on one side can make the knee drift inwards.

None of this means your walking is "wrong". But once a knee is painful, these patterns can keep irritating it. Small adjustments, such as a slightly shorter stride on downhill paths, supportive shoes, and hip strengthening so the pelvis stays level, reduce load without making walking feel unnatural.

Walking surface counts too. Uneven footpaths and steep slopes are harder on sore knees than a flat park track. Choosing flatter routes for a few weeks while strength builds keeps you walking rather than stopping altogether.

Outlook

Most knee pain while walking improves with a structured strengthening programme over six to twelve weeks. For stairs-specific pain, see our article on knee pain while climbing stairs.
