Sudden, or acute, kneecap pain is often caused by an injury. Common causes include: 1  Repetitive minor injuries; for example, while playing sports.  Forceful exercises and strains on the kneecap from running, jumping, squatting, deep knee bends, or falls.
The claim: Allowing your knees to move too far forward during exercises such as the squat and lunge places dangerous shearing forces on your knee ligaments. The origin: A 1978 study at Duke University found that keeping the lower leg as vertical as possible during the squat reduced shearing forces on the knee.
