Medial Collateral Ligament Tear

What Is a Medial Collateral Ligament (MCL) Injury?

The medial collateral ligament is a strong band on the inner side of the knee that helps stabilise the joint. An MCL injury is a sprain or tear of this ligament. Physiotherapy is a highly effective way to treat MCL injuries and support safe, timely recovery.

How Do MCL Injuries Happen?

An MCL injury usually occurs when the knee is forced to bend inward, overstretching the ligament. This often follows a direct impact to the outer side of the knee while the foot is planted, which can strain or tear the MCL.

Signs and Symptoms of an MCL Injury

Pain is typically felt along the inner (medial) side of the knee at the time of injury. You may also notice swelling and difficulty moving the joint. Other common symptoms include:

  • Reduced range of motion
  • Changes in walking pattern (gait)
  • Weakness around the knee
  • Balance or stability problems

What to Do If You Suspect an MCL Injury

For the first 24–48 hours, follow the RICE approach to control pain and swelling:

  • Rest: Limit weight through the leg; use crutches if walking is painful.
  • Ice: Apply for 15–20 minutes every 1–2 hours using crushed ice or frozen peas wrapped in a damp towel.
  • Compression: Use an elastic bandage for gentle support—snug, not tight.
  • Elevation: Lie with the knee propped on pillows so it sits above heart level. Continue RICE until you’re assessed by a physiotherapist—ideally within 48 hours.

What to Avoid with an MCL Injury

Avoid activities that increase blood flow and swelling around the injury, such as hot showers, heat rubs, alcohol, and excessive activity. These can worsen bleeding and inflammation and may prolong your recovery.

Physiotherapy Treatment for MCL Injuries

Physiotherapy is central to effective MCL rehabilitation. Your physiotherapist will identify which tissues are involved and how severe the injury is. When needed, they may recommend imaging (X-ray, ultrasound, CT, or MRI) to confirm the diagnosis and guide care. Based on findings, you’ll receive a tailored plan that may include:

  • Electrotherapy
  • Taping/strapping
  • Hydrotherapy
  • Proprioceptive (balance and control) exercises

Potential Long-Term Effects of an MCL Injury

Most MCL injuries heal within a few weeks with appropriate management. Recovery can take longer if other knee structures are injured at the same time. If the injury is not diagnosed or managed properly, the ligament may heal sub-optimally, leaving the knee more vulnerable to re-injury and ongoing instability.
