A knee sprain is when a force pushes the bones of the knee apart. If the force is strong enough, the ligament comes apart. This can happen from things like:
- Forced twisting of the knee
- A sudden change in direction
- A misstep that causes a sudden strain at a joint
- An impact with an object or another person
The doctor will ask about your symptoms and health history. You will also be asked how the injury happened. A physical exam will be done. It will focus on the knee.
It can be hard to tell a sprain from a fracture or dislocation. Pictures may be taken. This can be done with:
- MRI scan
The doctor may need to view the inside of the knee. This can be done with a minimally invasive procedure called an arthroscopy.

Treatment will depend on the joint and how severe the injury is. The goal of treatment is to ease pain and improve movement. Choices are:
- Supportive care, such as rest, ice, a compression bandage, and raising the knee to ease pain and swelling
- Medicine, such as over the counter pain relievers
- Supportive devices, such as a brace or crutches
- Physical therapy to improve strength, flexibility, and range of motion
Some people may need surgery to repair a ligament that is torn.
