There are a number of potential complications that may occur after surgery.
These may be grouped together as general complications that may occur after surgery and specific complications related to certain procedures.
General Complications
Drug reactions – Very occasionally medications and anaesthetic drugs may cause a reaction at the time of surgery – hence the need to let your doctors know about any allergies you may be aware of (even if the problem occurred many years ago).
DVT (deep venous thrombosis, blood clots) – These occur most commonly in the lower leg though occasionally can arise in the thigh or lungs. We usually take specific precautions to minimise this risk for all major surgery by using compression stockings (TED stockings), mechanical foot pumps, blood thinning medications and early mobilisation.
Operative Site Infections – We take specific precautions for every operation to prevent any infections occurring. This is especially important in joint replacement surgery. We routinely use antibiotics for 24 hours around the time of joint replacement surgery along with careful aseptic (sterile) techniques to minimise any risk. Risk of infection is usually under 2%.
Risk of other infections around the time of surgery
Urinary/bladder infections
Chest infections
These may occur after surgery and, in men, prostate problems should be identified and treated before major joint replacement surgery if possible.
Deep breathing exercises are important after surgery to help re-expand the lungs and minimise the risk of chest infections.
Heart/Lung/Kidney problems – If pre-existing problems exist then anaesthesia and surgery may act as a stress on the system. It is important to discuss any such problems before surgery so that preventative measures, if necessary, may be taken to minimise the risk.
Specific Surgery related problems
Hip Replacement Surgery
Infections are discussed above and if severe may require the hip replacement to be removed and re-inserted at a later date though this is a rare occurrence.
Dislocations occur rarely . Specific precautions are taken after hip replacement surgery to prevent this.
Leg length differences may occur infrequently but are usually very slight or not noticeable.
Nerve and blood vessel damage may occur but this is rare.
Knee Replacement Surgery
Infections are discussed above and if severe may require the knee replacement to be removed and re-inserted at a later date though this is a rare occurrence.
Knee stiffness may occur and physiotherapy is an important way to avoid the problem arising.
Nerve and blood vessel damage may occur but this is rare.
