ICD-10: S83.40

The ICD-10 code S83.40 refers to a sprain of the unspecified collateral ligament of the knee. This classification is part of the broader category of knee injuries, specifically focusing on ligamentous injuries that can occur due to various activities or trauma.

Clinical Description

Definition

A sprain is defined as an injury to a ligament, which is a band of fibrous tissue that connects bones at a joint. In the case of S83.40, the injury involves the collateral ligaments of the knee, which are crucial for stabilizing the joint during movement. The collateral ligaments include the medial collateral ligament (MCL) and the lateral collateral ligament (LCL). When the specific ligament involved is not identified, the code S83.40 is used.

Symptoms

Patients with a collateral ligament sprain may experience a range of symptoms, including:
- Pain: Localized pain around the knee joint, which may worsen with movement.
- Swelling: Inflammation and swelling around the knee, often due to fluid accumulation.
- Instability: A feeling of looseness or instability in the knee, particularly when bearing weight.
- Bruising: Discoloration around the knee may occur due to bleeding under the skin.

Mechanism of Injury

Collateral ligament sprains typically occur due to:
- Direct Trauma: A blow to the knee from the side, which can stretch or tear the ligament.
- Twisting Movements: Sudden changes in direction or pivoting can place excessive stress on the ligaments.
- Overextension: Hyperextension of the knee joint can also lead to sprains.

Diagnosis

Diagnosis of a collateral ligament sprain involves:
- Clinical Examination: A thorough physical examination to assess pain, swelling, and stability of the knee.
- Imaging Studies: MRI or ultrasound may be utilized to visualize the extent of the injury and rule out other associated injuries, such as meniscal tears or fractures.

Treatment

Treatment for a sprain of the collateral ligament typically includes:
- Rest: Avoiding activities that exacerbate the pain.
- Ice: Applying ice to reduce swelling and pain.
- Compression: Using elastic bandages to support the knee and minimize swelling.
