ICD-10: S83.131

The ICD-10 code S83.131 refers specifically to the medial subluxation of the proximal end of the tibia at the right knee. This condition is categorized under the broader classification of knee injuries and disorders, particularly focusing on subluxations and dislocations.

Clinical Description

Definition of Medial Subluxation

A subluxation is defined as a partial dislocation of a joint, where the surfaces of the joint are misaligned but still maintain some contact. In the case of S83.131, the medial subluxation indicates that the proximal end of the tibia (the upper part of the shinbone) has shifted medially (toward the midline of the body) at the knee joint. This can lead to instability in the knee and may affect the overall function of the joint.

Symptoms

Patients with a medial subluxation of the proximal tibia may experience a variety of symptoms, including:
- Pain: Localized pain around the knee, particularly on the medial side.
- Swelling: Inflammation and swelling around the knee joint.
- Instability: A feeling of the knee giving way or instability during movement.
- Limited Range of Motion: Difficulty in fully extending or flexing the knee.
- Bruising: Possible bruising around the knee area due to soft tissue injury.

Causes

The medial subluxation of the proximal tibia can result from several factors, including:
- Trauma: Acute injuries from falls, sports, or accidents that apply excessive force to the knee.
- Chronic Conditions: Degenerative diseases or conditions that weaken the ligaments and support structures of the knee.
- Anatomical Variations: Certain anatomical predispositions may increase the risk of subluxation.

Diagnosis

Diagnosis of S83.131 typically involves:
- Clinical Examination: A thorough physical examination to assess pain, swelling, and stability of the knee.
- Imaging Studies: X-rays or MRI scans may be utilized to visualize the extent of the subluxation and to rule out associated injuries, such as fractures or ligament tears.

Treatment

Treatment options for medial subluxation of the proximal tibia may include:
- Conservative Management: Rest, ice, compression, and elevation (RICE) to reduce swelling and pain.
- Physical Therapy: Rehabilitation exercises to strengthen the muscles around the knee and improve stability.
