What causes knee hyperextension?
It can happen to anyone but is more common in athletes in high-speed and contact sports and ski-ing. It is caused by a direct blow or the impact of forces released curing a sudden deceleration or stop. The knee joint is forced to bend the wrong way causing potential injury to knee ligaments.
Knee hyperextension symptoms
The pain can range from moderate to severe depending on the extent of the damage and the knee may feel unstable post injury. Bruising and swelling may result from tissue damage which can limit mobility.
Knee hyperextension treatment
Rest and recovery programmes allow the inflammation to subside and give the joint time to heal and moderate damage may only take two to four weeks to heal.
But an injured major ligament can need surgical reconstruction and a six-month rehabilitation plan. Some knee damage can be treated with arthroscopy but repair to the Anterior Cruciate Ligament (ACL) caused by hyperextension can involve surgery to remove the torn ligament and create a new one with a graft.
The procedure is effective and patients can return to full activity if they follow a gradual strengthening and mobility exercise strategy.

If you have medical insurance (e.g. Bupa, Axa PPP, Aviva), you will need to contact your insurer for authorisation for any treatment and, in most cases, you will require a referral letter from your GP. If you do not have a GP, then we have an in-house private GP practice that you can use. Alternatively we can suggest the most appropriate course of action for you to take, given your location and individual circumstance.
