Hyperextended knee.(Genu Recurvatum)
A hyperextended knee is an injury that happens when your knee is bent backward beyond its usual limit. Sports injuries and other traumas apply a lot of force to your knee's connective tissue (the tendons, ligaments and cartilage that hold it in place and help it move).
Symptoms.
Pain.
Swelling.
Trouble moving your knee like you usually can.
Instability or feeling like your knee is weaker than usual.
Bruising or discoloration.
Causes.
Most hyperextensions are caused during sports or other physical activities. Traumas like falling can also cause your knee to hyperextend. Anything that forces your knee backward can cause a hyperextended knee.
Test.
Stand in front of a full-length mirror and turn to the side. Take a look at your legs; are both legs straight and even, or does one knee dip back a bit farther than the other? It may be subtle and something you've not noticed before, or it may be more pronounced and something you've been concerned about.
Treatment.
Rest: Avoid the activity that caused your injury. ...
Ice: Apply a cold compress to your knee for 15 minutes at a time, four times a day.
Compression: You can wrap your knee in an elastic bandage to help reduce swelling.
Exercises.
swimming.
gentle hamstring stretches.
stationary bike.
straight leg raises.
wall sits.
lateral step-up.
quad sets — strengthening the quads (thigh muscles) by contracting, holding and releasing the muscles, placing a rolled towel under the knee for support if lying down.
Brace.
managing a hyperextending knee. In the case of quadriceps weakness which will not regain full strength, a specific knee orthosis to prevent hyperextension is a good option.
Surgery.
It's rare to need surgery after a hyperextended knee. However, if the injury that caused your hyperextension damaged tendons like your ACL or PCL, you might need surgery to repair those tears. Most of the time, surgery to repair damage in your knees is an outpatient procedure, which means you can go home the same day.
