Final answer:
The preadolescent's knee pain and swelling after playing sports could indicate several possible conditions, with an anterior cruciate ligament (ACL) injury and meniscal tear being common sports-related injuries that involve sudden changes in direction or twisting movements, respectively. Option b.
Step-by-step explanation:
When a preadolescent reports pain and swelling in the left knee after playing sports, several potential causes could be suspected by an Advanced Practice Registered Nurse (APRN). The options include:
- Anterior cruciate ligament (ACL) injury: commonly occurs with a forceful blow to the anterior knee, hyperextension, or a quick change of direction that produces twisting and hyperextension of the knee.
- Osgood-Schlatter disease: tends to occur during growth spurts when bones, muscles, tendons, and other structures are changing rapidly.
- Patellar tendonitis: an overuse injury affecting the patellar tendon that connects the kneecap to the shinbone, often seen in athletes who jump frequently.
- Meniscal tear: typically caused by a strong blow or twist of the knee, especially when the foot is planted.
The anterior cruciate ligament injury is particularly associated with sports that involve sudden stops or changes in direction. The meniscal tear can also occur during sports when the knee is swiftly twisted while the foot is planted. To determine the specific cause of the knee pain and swelling, the APRN may recommend diagnostic testing, such as an MRI or arthroscopy.
