In a patient with patellofemoral pain syndrome, which movement is most likely to provoke pain?

• A. Deep squats
• B. Walking on flat surfaces
• C. Straight leg raises
• D. Side lunges

Answer: (A)

In patients with patellofemoral pain syndrome, deep squats are particularly provocative for pain due to the increased compressive forces on the patellofemoral joint as the knee is flexed beyond 60 degrees. During a deep squat, the quadriceps muscle pulls the patella down into the femur, which can lead to irritation of the cartilage underneath the patella, worsening pain and discomfort. This syndrome typically results from malalignment or overuse of the knee joint, causing stress on the structures around the kneecap. When performing deep squats, the combination of knee flexion and weight-bearing positions exacerbates the symptoms, leading to increased pain. On the other hand, activities like walking on flat surfaces, straight leg raises, or side lunges do not typically create the same level of stress on the patella and surrounding structures when performed in a controlled manner, making them less likely to provoke acute pain in this condition.
