Pre-operative considerations of Knee Replacement Surgery
Prior to surgery you will require:- blood tests and xrays of your knee. You may also require a chest xray and echocardiogram (ECG).
A urine sample will also be taken to exclude any underlying infection and you will be checked to ensure you are not a carrier for MRSA. (Methicillin Resistant Staphylococcus Aureus)
Patients on Aspirin or other anticoagulants such as Warfarin and Clopidogrel need to cease taking the medication 5-7 prior to surgery. Advice will be given as to whether other medication needs to be substituted. Blood tests will be required just before surgery to ensure clotting factors are back to normal.
If there is any sign of infection such as a skin rash, tooth abscess or dental decay, chest infection, these need to be treated prior to surgery as they are a potential source of infection for your prosthesis.
If you are a smoker you are at an increased risk of a chest infection following your procedure. If possible reduce or give up smoking prior to the operation.
Post operative knee function is determined by pre-operative function. Hence the more you exercise and strengthen your muscles prior to surgery, the better your outcome will be after surgery!
You will have the opportunity to discuss your anaesthetic with the anaesthetist prior to the procedure.
