Final answer:
The 14-year-old basketball player may have patellofemoral syndrome, also known as runner's knee, which is characterized by knee pain and swelling of the tibial tubercle. This condition is common among athletes who engage in activities that involve repetitive knee bending movements. The exact cause of patellofemoral syndrome is not fully understood, but factors such as overuse, muscle imbalances, and biomechanical issues may contribute to its development.
Step-by-step explanation:
The 14-year-old basketball player with knee pain and swelling of the tibial tubercle could have patellofemoral syndrome, also known as runner's knee. This condition is common among athletes, especially runners, and is characterized by a dull, aching pain around the front of the knee. It is often caused by excessive running, downhill running, or repetitive knee bending movements.
The tibial tubercle is a bony prominence where the patellar tendon attaches. In some cases, irritation and inflammation of this area can occur, resulting in pain and swelling. The exact cause of patellofemoral syndrome is not fully understood, but factors such as overuse, muscle imbalances, and biomechanical issues can contribute to its development.
To confirm the diagnosis of patellofemoral syndrome, a healthcare professional would need to perform a physical examination and potentially order additional tests such as an X-ray or MRI to rule out other possible causes and assess the severity of the condition.
