Lateral collateral ligament (LCL) damage is a common knee injury that affects the ligament on the outer side of the knee joint. The LCL helps to stabilize the knee and prevent excessive movement of the lower leg bone (fibula) in relation to the upper leg bone (femur). LCL injuries can range from a mild sprain to a complete tear of the ligament.

Symptoms of LCL injury may include pain on the outer side of the knee, swelling, tenderness, and difficulty moving the knee. In more severe cases, there may be instability or a feeling of giving way in the knee.


Treatment for LCL injury typically involves a combination of physiotherapy, medications, bracing, and in some cases, surgical intervention. The decision to undergo surgery will depend on the severity of the injury, the patient’s age and activity level, and the extent of knee instability. Physiotherapy is an important component of pre- and post-operative care and can help to promote healing, reduce pain and inflammation, and restore function and mobility in the knee joint.


Applying the 5 stages of rehab to LCL injury and achieving the best possible outcome are as follows:.


Pain and symptom management: The primary goal is to reduce pain and inflammation. Rest, ice, compression, and elevation (RICE) are often recommended in the initial stages of treatment. Pain-relieving medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) may also be prescribed to manage pain and reduce inflammation. Physiotherapy treatments such as ultrasound, soft tissue massage, and taping can also help to reduce pain and swelling.

Range of motion: Once pain and inflammation are under control, the focus shifts to restoring normal range of motion in the knee joint. Physiotherapy treatments such as gentle mobilization, stretching exercises, and joint mobilization techniques can help to improve flexibility and reduce stiffness in the knee joint.

Motor control: In stage 3, the focus is on improving neuromuscular control around the knee joint. Exercises that target the quadriceps, hamstrings, and calf muscles, can help to improve muscle strength, balance, and coordination. Proprioceptive training, which involves exercises that challenge balance and coordination, can also be beneficial in improving motor control.

Strengthening: In stage 4, the goal is to build strength in the muscles around the knee joint to improve stability and reduce the risk of reinjury. Resistance training, including exercises such as squats, lunges, and leg presses, can help to build muscle strength and endurance. Plyometric exercises, which involve jumping and landing, can also help to improve power and explosiveness in the lower limb muscles.

Maintenance: In the final stage of rehab, the focus is on maintaining the gains achieved in the previous stages and preventing reinjury. This may involve continuing with regular exercise, including strengthening and proprioceptive training, as well as making any necessary modifications to daily activities or sports participation to reduce the risk of further injury.
