When to worry about kneecap pain with patellofemoral pain syndrome

Patellofemoral Pain Syndrome involves pain around or behind the kneecap, often aggravated by stairs, squatting, running, or sitting with the knee bent for a long time. The knee may feel tired or click without a dangerous problem. A new injury, true locking, repeated giving way, or substantial swelling changes the picture.

Modify activities rather than pushing through sharp or escalating pain. Choose comfortable walking and gentle range-of-motion work, and reduce deep knee bends temporarily. Note which loads bring symptoms on and whether the knee swells afterward. A physiotherapist can assess hip and thigh strength, movement habits, and a gradual exercise plan.

Book an assessment if symptoms do not improve with sensible activity changes, repeatedly disturb sleep, or limit ordinary movement. Seek prompt care for a knee that locks, gives way repeatedly, becomes markedly swollen, or cannot bear weight. Urgent review is needed for a hot swollen knee with fever, severe pain after injury, or a foot that becomes numb, pale, blue, or cold.

Ask which movements are safe, whether an examination can identify the pain source, and how to progress strengthening. Describe any injury, swelling, locking, giving way, altered walking, or symptoms in the hip or ankle.
