LCL Injury

What is an LCL Injury?

An LCL (lateral collateral ligament) injury involves damage to the ligament on the outer side of the knee, resulting in pain and instability.

• Injury to the lateral knee ligament
• Commonly occurs from a varus stress injury

Overview of the Condition

LCL injuries can range from mild sprains to complete tears, affecting knee stability during lateral movements.

Symptoms

• Lateral knee pain and swelling
• Instability or giving way of the knee
• Bruising and tenderness over the LCL

Causes

Typically results from a direct blow to the medial knee or twisting injuries that place stress on the lateral side.

Diagnosis

Diagnosis is made with a physical examination and confirmed with imaging studies such as MRI.

Treatment Options

• Conservative management with rest and bracing
• Physical therapy to strengthen surrounding muscles
• Surgical repair for complete tears

Conservative Management

Initial treatment includes rest, ice, compression, and elevation (RICE) along with knee bracing.

Rehabilitation Exercises

1. Range-of-motion exercises
2. Strengthening exercises for the lateral knee and hip abductors
3. Balance and proprioception training

Surgical Options

Surgical intervention is reserved for complete LCL tears or cases that fail to improve with conservative management.

Anatomy Overview

The LCL runs along the lateral aspect of the knee, providing stability against varus forces.

Affected Areas

• Lateral knee
• Surrounding soft tissues
