ICD-10: S83.429

The ICD-10 code S83.429 refers to a sprain of the lateral collateral ligament (LCL) of the knee, specifically when the injury is unspecified. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for accurate diagnosis and effective management.

Clinical Presentation

Overview of Lateral Collateral Ligament Sprains

The lateral collateral ligament is a key stabilizing structure on the outer side of the knee. Sprains can occur due to various mechanisms, often involving a sudden force or trauma that causes excessive lateral movement of the knee. This injury is common in sports and activities that involve quick changes in direction or contact.

Signs and Symptoms

Patients with an LCL sprain may exhibit a range of signs and symptoms, including:

• Pain: Localized pain on the outer side of the knee, which may worsen with movement or pressure.
• Swelling: Swelling around the knee joint, which can develop shortly after the injury.
• Bruising: Discoloration may appear around the knee, indicating bleeding under the skin.
• Instability: A feeling of instability or weakness in the knee, particularly when bearing weight or during lateral movements.
• Limited Range of Motion: Difficulty in fully extending or flexing the knee due to pain and swelling.
• Tenderness: Tenderness upon palpation of the lateral aspect of the knee, particularly over the LCL.

Functional Impairment

Patients may report difficulty in performing daily activities, such as walking, climbing stairs, or participating in sports. The severity of symptoms can vary based on the degree of the sprain, which is classified into three grades:

1. Grade I (Mild): Minor stretching of the ligament with minimal pain and swelling.
2. Grade II (Moderate): Partial tear of the ligament with moderate pain, swelling, and some instability.
3. Grade III (Severe): Complete tear of the ligament, resulting in significant pain, swelling, and marked instability of the knee.
