Understanding Knee Pain in Adolescents

Knee pain in children and adolescents can stem from various causes and present with a range of symptoms. This section explores the common causes and symptoms associated with knee pain in young athletes.

Causes of Knee Pain

Injuries: Knee injuries in children and adolescents are often caused by falls, accidents, or overuse during sports activities. These injuries can lead to damage to different parts of the knee such as cartilage, tendons, and ligaments.
ACL Injuries: Anterior cruciate ligament (ACL) injuries are common, especially in activities involving cutting, pivoting movements, landing after jumping, or direct blows to the knee. ACL injuries can be partial or complete tears, leaving the knee unstable [2].
Jumper’s Knee: Also known as patellar tendonitis, this overuse injury affects the patellar tendon and causes knee pain, swelling, and joint stiffness, particularly in sports involving jumping, squatting, climbing, and running [2].
Osgood-Schlatter Disease: This condition is an overuse injury of the cartilage growth plate just below the knee. It commonly affects boys ages 12-18 and girls ages 10-16 who are active in sports. Symptoms include knee pain, inflammation, limping, and a bump at the top of the shinbone.

Symptoms of Knee Pain

General Symptoms: Common signs and symptoms of knee injuries in kids and teens include pain, weakness, feeling like the knee is "giving way" or "locking," inability to fully bend or straighten the knee, swelling, and bruising.
Anterior Knee Pain: The most common symptom is a dull, achy pain that starts gradually and is related to activity. Swelling, clicking, locking, snapping, or the knee giving way are less common symptoms.
Patellofemoral Pain Syndrome (PFPS): Signs include dull, aching pain around, behind, below, or on the sides of the kneecap, swelling, knee buckling, popping or grinding sensation during knee flexion and extension, and increased pain during specific activities like running downhill, going up and down stairs, deep knee bends, or prolonged sitting or standing.

Diagnosing Knee Injuries in Adolescents

Diagnosing knee injuries in children and teens is crucial for effective treatment and recovery. This section outlines the steps involved in medical evaluation and imaging tests.

Medical Evaluation

Doctors diagnose knee injuries by first inquiring about how the injury occurred. They ask questions about the child's activity, the onset and nature of the pain, and any previous knee issues. This initial assessment helps narrow down potential causes.

Next, a physical exam is conducted. The healthcare provider presses on various parts of the knee and legs to pinpoint the location of the pain. They may also check for swelling, bruising, or deformities and assess the range of motion and stability of the knee joint.

Here’s a summary of typical steps in a medical evaluation:

Inquiry: Questions about the injury's occurrence and symptoms.
Observation: Visual inspection for swelling, bruising, or deformities.
Palpation: Pressing on the knee to identify painful areas.
Movement: Assessing range of motion and stability.

Imaging Tests

Imaging tests are often necessary to accurately diagnose knee injuries in adolescents. These tests help identify the injured part of the knee and determine the extent of the damage [5].

Common Imaging Tests:

X-rays: Used to detect fractures or bone abnormalities.
CT Scans: Provide detailed images of the bone and surrounding tissues.
MRIs: Offer the most detailed images, useful for identifying soft tissue injuries like ligament tears.

Imaging Test	Purpose
X-rays	Detect fractures or bone abnormalities
CT Scans	Detailed images of bone and tissues
MRIs	Detailed soft tissue images, ligament tears

For a more tailored approach, doctors may also consider factors such as age and activity level. Adolescents aged 12-14 and 15-17 are at a higher risk for knee pain [6]. Participation in physical education at school is a protective factor, as those who do not partake report more knee pain [6].

Effective diagnosis is the first step towards managing knee pain. For more information on non-surgical treatments, visit our article on pain management options for knee arthritis. Additionally, understanding the role of diet in managing knee pain can be beneficial for long-term care.
