A 26-year-old basketball player complains of a sudden sharp pain in his knee after jumping for a rebound during a game. He is having difficulty bearing weight on the affected leg. What might be the potential diagnosis?
This athlete's injury could indicate patellar tendonitis, also known as "jumper's knee". It is an injury to the tendon connecting the kneecap to the shinbone, often caused by repetitive stress on the knee, especially from jumping activities.
