We will anaesthetise your leg via an injection in the back of your knee (Popliteal block). This will be carried out by Miss Feeney on the ward with adequate time given to allow the local anaesthetic to take effect.
As the anatomy behind the knee varies a little from person to person we use a nerve stimulator to locate the nerves. This sends a small electric current down the needle which stimulates the nerve. This means that the muscles controlled by the nerve begin to contract and relax causing the foot to ´flick´. Whilst this is a strange sensation, it is not uncomfortable and helps us to deliver the anaesthetic with precision.
Local anaesthetic at the level of the knee not only blocks sensation but also movement of your foot. This is temporary lasting for 24
