Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Patellar tendinopathy (jumper's knee)
Patellar tendinopathy is an overuse injury of the proximal patellar tendon at its origin on the inferior pole of the patella, common in jumping athletes. Pain is worse after loading and there is local tenderness. Eccentric loading exercises are the mainstay of treatment.
Option by option

B. Osgood-Schlatter disease
Osgood-Schlatter disease affects the tibial tubercle in adolescents.
C. Prepatellar bursitis
Prepatellar bursitis causes swelling over the front of the patella without tendon thickening.
D. Medial meniscus tear
A meniscal tear causes joint line pain and locking.
