The ankle and knee are joints located in the lower leg. Injuries to these joints are very common reasons why people visit their GP or physiotherapist. Injuries that frequently affect these joints include ligament sprains, muscle and tendon strains, and damage to the meniscus (cartilage) in the knee. Although these injuries are often painful and uncomfortable, they can usually be managed with rest, ice, support and a gradual return to physical activity.
In some cases, such as when the cause of the injury is unclear or the damage to the joint is complex, an imaging test, such as an X-ray, ultrasound or magnetic resonance imaging (MRI), may be recommended. However, research shows that in most cases of acute ankle and knee sprain/strain, having an X-ray or MRI does not change the treatment you receive or how fast you recover. In addition, having an X-ray you don’t need may expose you to unnecessary radiation. In fact, for many sprains affecting the ankles and knees, taking a history and examining the joint is all that your health professional will need to do to determine the diagnosis and guide management.
