It occurs when the ligaments in the knee are stretched, torn, or damaged.
The knee has four main ligaments:
- Anterior cruciate ligament (ACL)
- Posterior cruciate ligament (PCL)
- Medial collateral ligament (MCL)
- Lateral collateral ligament (LCL)
Ligament injuries can range from mild strains to complete tears and can occur as a result of sports injuries, falls, or other trauma.
Symptoms of Knee Ligament Injuries
- Pain and tenderness in the knee
- Swelling and bruising around the knee joint
- Limited range of motion or difficulty moving the knee
- Instability or feeling like the knee is giving way
- Popping or snapping sensation at the time of injury

Grade 1 Ligament Sprains: These are mild injuries characterized by slight stretching or microscopic tearing of the ligament fibers.
Treatment often includes:
- Rest to allow healing.
- Ice and compression for pain and swelling.
- Gentle rehabilitation exercises to regain strength and stability.
Grade 2 Ligament Injuries: These involve partial tearing of the ligament and may require more intensive care.
- Immobilization with a brace to prevent further damage.
- Supervised physical therapy for strengthening and restoring range of motion.
- Potential use of crutches to avoid weight-bearing on the injured knee.
Grade 3 Ligament Tears: The most severe type, with a complete rupture of the ligament. Treatment options are more extensive.
- Surgical intervention, such as ligament reconstruction.
- Post-surgery physical therapy to regain strength, stability, and function.
- Prolonged recovery and rehabilitation period.
