Hyperextended knee: What are the treatment options?

Hyperextended knee refers to an injury in which the knee is forced beyond its normal fully straightened position. This position forces the lower leg excessively forward in relation to the upper leg. Hyperextension of the knee often occurs as a result of an awkward landing after a jump or from a contact injury to the lower leg. It is a common injury in jumping or leaping sports, such as gymnastics, basketball and some types of dance.

Treatment of hyperextended knee depends on the severity of the injury. Sometimes the damage is relatively minor, with pain and swelling when you try to extend your knee. But a hyperextended knee may also lead to a partial or complete ligament tear, especially in your anterior cruciate ligament (ACL). An injury severe enough to cause knee joint swelling, instability, impaired motion or pain should be evaluated by a doctor.

A doctor can evaluate the injury by:

• Medical history
• Physical examination of the knee
• X-rays of the knee
• Magnetic resonance imaging (MRI) scans

Treatment may include:

• Applying ice to the knee immediately after the injury
• Rest
• Over-the-counter pain relievers, such acetaminophen or anti-inflammatory medications
• Physical therapy
• Surgery
