ICD-10: M92.521

Juvenile osteochondrosis of the tibia tubercle, classified under ICD-10 code M92.521, is a condition primarily affecting adolescents and is characterized by the disruption of normal bone growth at the tibial tuberosity. This condition is often associated with pain and functional limitations, particularly in active children and adolescents. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this diagnosis.

Clinical Presentation

Definition and Pathophysiology

Juvenile osteochondrosis of the tibia tubercle, commonly known as Osgood-Schlatter disease, occurs due to repetitive stress and traction on the growth plate (apophysis) at the tibial tuberosity. This area is where the patellar tendon attaches to the tibia, and excessive physical activity, particularly in sports involving running and jumping, can lead to inflammation and pain in this region[1][2].

Age Group

This condition typically presents in children and adolescents aged 10 to 15 years, with a higher incidence in those who are physically active. It is more common in boys than girls, although the gender gap narrows after the onset of puberty[3].

Signs and Symptoms

Common Symptoms

1. Knee Pain: The most prominent symptom is localized pain at the tibial tuberosity, which may worsen with activity and improve with rest[4].
2. Swelling: There may be noticeable swelling over the tibial tuberosity, which can be tender to touch[5].
3. Pain with Activity: Activities such as running, jumping, or climbing stairs often exacerbate the pain, leading to decreased participation in sports[6].
4. Stiffness: Patients may experience stiffness in the knee joint, particularly after periods of inactivity[7].

Physical Examination Findings

• Tenderness: Direct palpation of the tibial tuberosity typically elicits tenderness.
• Swelling: Swelling may be present, and in some cases, a prominent bony lump can be felt at the site of the tuberosity.
• Range of Motion: While the range of motion in the knee may be preserved, pain can limit full extension or flexion during active movements[8].

Patient Characteristics

Risk Factors

• Physical Activity: Increased participation in sports, especially those involving running and jumping, is a significant risk factor for developing this condition[9].
• Growth Spurts: The onset of symptoms often coincides with periods of rapid growth, which can place additional stress on the knee joint[10].
• Biomechanical Factors: Abnormalities in lower limb biomechanics, such as flat feet or improper footwear, may contribute to the development of Osgood-Schlatter disease[11].

Demographics

• Gender: Males are more frequently affected than females, particularly before the onset of puberty. However, the incidence in females increases post-puberty due to increased participation in sports[12].
• Activity Level: Active children and adolescents are at a higher risk, particularly those involved in sports that require repetitive knee flexion and extension[13].

Conclusion

Juvenile osteochondrosis of the tibia tubercle (ICD-10 code M92.521) is a common condition in active adolescents, characterized by knee pain, swelling, and tenderness at the tibial tuberosity. Understanding the clinical presentation, signs, symptoms, and patient characteristics is crucial for timely diagnosis and management. Treatment typically involves rest, ice, and anti-inflammatory medications, with most patients experiencing resolution of symptoms with conservative management over time[14]. If symptoms persist or worsen, further evaluation by a healthcare professional may be necessary to rule out other conditions.
