S83.145
Lateral dislocation of proximal end of tibia, left knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Lateral dislocation of the proximal end of the tibia in the left knee is a rare but serious injury where the upper part of the tibia (shinbone) moves out of its normal position relative to the femur (thighbone). This injury occurs on the outer (lateral) side of the knee and typically results from trauma or significant force applied to the joint. Recognizing and understanding this injury is important to facilitate appropriate medical attention and recovery.
Causes & Symptoms
Clinical Causes: Severe impact or trauma during accidents, falls, or sports injuries Twisting or rotational forces applied to the knee joint High-energy injuries such as car accidents Motorcycle or bike crashes Direct blows to the knee that cause significant displacement
Key Symptoms: Sudden, severe pain in the affected knee Visible deformity where the tibia appears out of alignment Swelling around the knee joint Inability or difficulty moving the knee Instability or a feeling that the knee is 'giving way' Tenderness to touch around the joint Possible bruising or discoloration
Diagnostic & Treatment
Diagnosis Path: X-ray: The primary imaging technique used to visualize the dislocation and assess for associated fractures MRI: May be ordered if soft tissue injuries such as ligament tears are suspected CT scan: Occasionally used for detailed bone assessment if complex fractures or displacements are involved
Treatment Protocols: Emergency stabilization and pain management Closed reduction: The healthcare provider manually realigns the tibia and femur without surgery Immobilization: The knee is stabilized using a cast, brace, or splint after successful realignment Rest and elevation to reduce swelling Ice application to decrease pain and inflammation Surgical intervention: May be necessary if the dislocation is unstable, if there are associated fractures, or if closed reduction is unsuccessful Post-reduction imaging to confirm proper alignment Rehabilitation and physical therapy to restore strength, stability, and range of motion
