Subluxation and dislocation of knee

Clinical Classification Guidelines

Excludes Type 2

  • instability of knee prosthesis (T84.022, T84.023)

Medical Intelligence & Overview

The ICD-10 code S83.1 refers to injuries involving the subluxation and dislocation of the knee joint. These injuries occur when the bones forming the knee are displaced from their normal alignment. While dislocation involves a complete displacement of the bones, subluxation refers to a partial dislocation where the joint surfaces lose contact but do not become completely separated. The knee is a complex joint that bears the body's weight, making injuries to it potentially serious and requiring proper diagnosis and management.

Causes & Symptoms

Clinical Causes: Trauma from falls or direct blows to the knee Sports injuries, especially in activities involving sudden twists or impacts High-impact accidents or car collisions Sudden twisting or rotational forces applied to the knee Previous knee injuries weakening the supporting structures

Key Symptoms: Severe pain around the knee joint Swelling and tenderness Visible deformation or abnormal position of the knee Inability to move or bear weight on the leg A feeling of the knee giving way or instability Bruising around the knee

Diagnostic & Treatment

Diagnosis Path: Diagnosis of knee subluxation and dislocation is primarily based on a physical examination and imaging tests. The doctor will assess the alignment, stability, and range of motion of the knee. Imaging studies such as X-rays are crucial for confirming the diagnosis, determining the extent of dislocation or subluxation, and identifying any associated fractures or damage to ligaments and cartilage.

Treatment Protocols: Treatment options for subluxation and dislocation of the knee depend on the severity of the injury. Common approaches include: - **Reduction**: The healthcare provider manually realigns the knee bones to their proper positions. This is usually performed under anesthesia or sedation. - **Immobilization**: After realignment, the knee may be placed in a brace or splint to prevent movement and allow healing. - **Pain management**: Use of medications to reduce pain and inflammation. - **Rehabilitation**: Physical therapy to restore strength, flexibility, and function of the knee joint. - **Surgical intervention**: In cases of complex dislocations, ligament tears, or associated fractures, surgery may be necessary to repair damaged structures. Following treatment, a period of rest and gradual return to activity is recommended to promote healing and prevent recurrence.

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
