Lateral Collateral Ligament Tear

What is a Lateral Collateral Ligament (LCL) Injury?

The lateral collateral ligament (LCL) is a strong band of tissue located on the outer side of the knee that helps stabilise the joint. An LCL injury occurs when this ligament is overstretched or torn, often referred to as a sprain. Physiotherapy plays a vital role in both recovery and preventing future reinjury.

How Does a Lateral Collateral Ligament Injury Occur?

An LCL injury typically happens when the knee is forced to bend outward, overstretching the ligament. This is most often caused by a direct blow to the inside of the knee while the foot is firmly planted on the ground, leading to pain and structural damage.

What are the Symptoms of an LCL Injury?

The first sign of an LCL injury is usually pain along the outer edge of the knee. Some people may also hear or feel a snap, pop, or tearing sensation at the moment of injury. The joint often becomes swollen and walking can be difficult. Additional symptoms include:

  • Stiffness in the knee
  • Gait (walking) difficulties
  • Problems with balance
  • Muscle spasms around the joint

What Should I Do if I Suspect an LCL Injury?

In the first 24–48 hours, follow the RICE protocol (Rest, Ice, Compression, Elevation) to control swelling and pain:

  • Rest: Reduce weight-bearing on the injured leg; crutches may be needed if walking is painful.
  • Ice: Apply a cold pack or frozen peas wrapped in a damp towel for 15–20 minutes every 1–2 hours.
  • Compression: Use an elastic bandage to support the knee, keeping it snug but not overly tight.
  • Elevation: Raise the leg on pillows or a chair so the knee is higher than the heart.

A physiotherapy assessment should be arranged within 48 hours to confirm the injury and begin treatment.

Physiotherapy Treatment for LCL Injuries

Physiotherapy is essential in guiding recovery from an LCL injury. A physiotherapist will assess the extent of the damage and may recommend imaging tests (such as X-ray, ultrasound, CT, or MRI) for a clearer diagnosis. Treatment usually includes:

  • Hydrotherapy – gentle water-based exercises to restore mobility
  • Electrotherapy – reducing pain and swelling with electrical stimulation
  • Massage therapy – improving circulation and relieving stiffness
  • Taping or strapping – providing external support and stability during activity

A personalised rehabilitation plan will be developed to speed up healing and restore normal function.

What Should I Avoid with an LCL Injury?

After an LCL injury, avoid activities that increase blood flow to the area, as they can worsen swelling and bleeding. These include:

  • Hot showers or heat rubs
  • Alcohol consumption
  • Excessive physical activity

These actions may delay recovery and prolong discomfort.

Could There Be Long-Term Effects from an LCL Injury?

Most lateral collateral ligament injuries heal within a few weeks with proper treatment. However, recovery may take longer if other knee structures are injured at the same time. If left untreated or not managed correctly, the ligament may heal poorly, making the knee more vulnerable to repeated injuries and long-term instability.
