Why do my knees hurt when I squat or climb stairs?

Pain at the front of the knee is common and often related to how much load the joint has been exposed to compared with what it can handle, not to a structural fault. Weak hips or thighs, sudden increases in activity and sitting for long periods can all contribute.

Strengthening the glutes and quads and progressing slowly usually helps. If it persists or comes with swelling, see a professional.
