ICD-10: S83.111

The ICD-10 code S83.111 refers specifically to the anterior subluxation of the proximal end of the tibia at the right knee. This condition is characterized by a partial dislocation where the tibia shifts forward relative to the femur, which can lead to instability and pain in the knee joint. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

Anterior subluxation of the proximal end of the tibia occurs when the tibia is displaced anteriorly (forward) in relation to the femur at the knee joint. This condition can result from trauma, such as a sports injury, or may develop due to chronic instability or degenerative changes in the knee.

Symptoms

Patients with anterior subluxation of the proximal tibia may experience:
- Knee Pain: Often localized around the knee joint, particularly during movement.
- Swelling: Inflammation may occur due to injury to surrounding tissues.
- Instability: A feeling of the knee giving way, especially during weight-bearing activities.
- Limited Range of Motion: Difficulty in fully extending or flexing the knee.

Causes

The primary causes of anterior subluxation include:
- Traumatic Injuries: Such as falls, direct blows to the knee, or sudden twisting motions.
- Ligamentous Injuries: Damage to the anterior cruciate ligament (ACL) can predispose individuals to subluxation.
- Chronic Conditions: Conditions like osteoarthritis may lead to joint instability over time.

Diagnosis

Clinical Evaluation

Diagnosis typically involves a thorough clinical evaluation, including:
- Patient History: Understanding the mechanism of injury and symptom onset.
