What should you know about patellofemoral pain syndrome in runners?

The discomfort usually builds with repeated knee loading rather than appearing as one dramatic injury. A runner may feel aching at the front of the knee during a run, after hills or speed work, while descending stairs, or when standing after sitting. Clicking can occur without meaning the joint is being damaged.

Training changes, reduced hip or thigh strength, limited movement elsewhere in the leg, footwear changes, and a sudden increase in distance or intensity can all alter how load is shared. A clinician checks the knee and the way you squat, step, or run because several problems can cause similar pain.

Temporarily reduce the activity that clearly provokes symptoms, such as hills, deep squats, or fast intervals, while keeping comfortable movement. Ice may soothe a flare. Rehabilitation commonly builds hip, thigh, and calf strength, then gradually returns to running with changes in pace, terrain, or volume. Increase one training demand at a time and note how the knee feels during activity and later that day. A physiotherapist can help match exercises to your running pattern.

Arrange an assessment if pain persists despite sensible training changes, repeatedly interrupts running, or causes a limp. Seek prompt care after a twisting injury with marked swelling, locking, giving way, or inability to bear weight. Urgent assessment is appropriate for a hot, red, swollen knee with fever or for severe pain after a direct impact.

Ask which running loads should change first, whether your hip and thigh strength need testing, and how to progress exercises. Clarify whether your symptoms fit patellofemoral pain or another knee problem, and which warning signs should stop training.
