The knee receives a lot of use every day. It is the largest joint in the body that is necessary for walking, running, jumping and climbing.

Due to constant use, the ligaments of the knee are susceptible to injury. If you are experiencing knee pain, your doctor may advise you to strengthen the knee with physical therapy.

Ligaments of the Knee

Ligaments of the Knee

There are 4 main ligaments of the knee. Ligaments provide strength and stability to the knee. They are elastic bands that attach the bones together.

4 Main Knee Ligaments:

Anterior cruciate ligament (ACL)

ACL injuries are the most common types of knee injuries. The ACL is found in the center of the knee. It connects the shinbone to the thighbone. It is one of the main stabilising ligaments that controls rotation and forward movement of the shin bone. When the anterior cruciate ligament is severely injured, it often requires surgery to regain full function.

Posterior cruciate ligament (PCL)

The PCL is located at the back of the knee. It connects the shinbone to the thighbone. It works in conjunction with the ACL. However, it isn’t injured as easily as the ACL. When the Posterior cruciate ligament is injured you may notice a feeling of instability and pain.


Medial collateral ligament (MCL)

The MCL is located along the inner knee. It connects the shinbone to the thighbone. It provides stability to the inner knee. It works with the Lateral collateral ligament to hold the knee in place. The medial collateral ligament is often injured when the outside of the knee experiences a collision, pushing the knee sideways.


Lateral collateral ligament (LCL)

The LCL is located along the outer knee. It connects the shinbone to the thighbone. It provides stability to the outer knee. It works with the medial collateral ligament to hold the knee in place. The lateral collateral ligament is typically injured when the inside of the knee experiences a direct force.

Diagnosis of Knee Ligament Injury

Your doctor may be able to diagnosis your knee injury with a physical examination. However, other diagnostic procedures may be required.

  • X-ray
  • Magnetic resonance imaging (MRI)
  • Arthroscopy
  • Ultrasound
  • Computerized tomography (CT) scan

How to Strengthen the Knee

Exercise is the best way to strengthen the knee. It is often recommended instead of surgery. Strengthening the muscles will help support the knee and prevent future injuries.

Exercising the knee doesn’t only help the knee; it strengthens the leg muscles as well. Strong leg muscles can relieve pressure on the knees aiding in the prevention of strain and injury.

Before starting an exercise routine, you should speak to your doctor. If you experience any pain, stop immediately.

Exercises to Strengthen the Knee:

  • Leg Lifts
  • Hamstring Curls
  • Step Exercises
  • Chair Dips
  • Squats
  • Lunges
  • Calf Raises
  • Hip Bridge
