ICD-10: S83.134

The ICD-10 code S83.134 refers specifically to the medial dislocation of the proximal end of the tibia in the context of the right knee. This condition is categorized under the broader classification of knee injuries and dislocations, particularly focusing on the dislocation of the tibia relative to the femur at the knee joint.

Clinical Description

Definition

A medial dislocation of the proximal end of the tibia occurs when the tibia is displaced medially (toward the midline of the body) at the knee joint. This type of dislocation can result from trauma, such as a fall, sports injury, or a vehicular accident, where excessive force is applied to the knee.

Symptoms

Patients with this condition may present with several symptoms, including:
- Severe pain in the knee area, particularly on the medial side.
- Swelling and bruising around the knee joint.
- Deformity of the knee, which may be visibly apparent.
- Limited range of motion, making it difficult to bend or straighten the knee.
- Instability of the knee joint, leading to difficulty in weight-bearing activities.

Diagnosis

Diagnosis typically involves a combination of:
- Physical examination: Assessing the knee for swelling, tenderness, and range of motion.
- Imaging studies: X-rays are commonly used to confirm the dislocation and rule out associated fractures. In some cases, MRI may be utilized to evaluate soft tissue injuries.

Treatment

Treatment for a medial dislocation of the proximal end of the tibia generally includes:
- Reduction: The primary goal is to realign the dislocated tibia back into its proper position, which may be done manually or surgically, depending on the severity and associated injuries.
- Immobilization: After reduction, the knee may be immobilized using a brace or splint to allow for healing.
- Rehabilitation: Physical therapy is often recommended to restore strength and range of motion once the initial healing has occurred.
