Pain in PFPS typically worsens with which activity?

Pain in PFPS typically worsens with which activity?

• A. Loading activities such as running or squatting
• B. Rest
• C. Non-weight-bearing activities
• D. Traumatic impact to the knee

Answer: (A)

Pain in PFPS is driven by loading the patellofemoral joint. When the knee bends and the quadriceps contract, the patella is pressed against the femur, increasing contact pressure and stressing the peri-patellar tissues. Activities like running or squatting heighten knee flexion and quad activation, which amplifies this stress and tends to provoke pain. Rest or non-weight-bearing activities reduce joint loading, so the pain is typically alleviated. Traumatic impact is not characteristic of PFPS, which is an overuse/irritation problem rather than an acute injury.
