Step-by-step explanation:
The student's symptoms of chronic anterior knee pain that worsen with climbing stairs are indicative of Patellofemoral pain syndrome, also known as runner's knee. The condition is most common in runners, but can also occur in athletes who participate in activities that involve repetitive knee bending, such as jumpers, skiers, cyclists, weightlifters, and soccer players. The pain is typically felt around the front of the knee, deep to the patella, and can be aggravated by activities like walking, running, kneeling, squatting, or sitting with the knee bent for a prolonged period.
