Knee injury
Knee injuries can cause pain, swelling and instability (the feeling that your knee is going to give way). They’re often caused by ligament damage.
Knee osteoarthritis
Osteoarthritis is a disease that causes pain and stiffness in your joints. Your knee is one of the joints that’s most commonly affected.
Lateral collateral ligament (LCL) injury
An LCL injury is often associated with injuries to the ligaments and tendons in this area, as well as to other parts of the knee.
Medial collateral ligament (MCL) injury
The MCL is the most commonly injured knee ligament. It often gets injured during sports such as rugby.
