Guidelines for Patients Having Total or Partial Knee Replacements Potential Complications of Knee Replacement Surgery Incidence The majority of patients who undergo knee replacement surgery have a pleasant experience without any complications Of all patients who undergo total knee replacements more than 96 have no complications The following is a comprehensive list of all problems that could potentially occur For informed consent it is important that you know of these problems but please be reassured that the vast majority of patients suffer no complications Pain Conclusion We hope that you have found this booklet useful and that it has helped to relieve some of your fears and anxieties regarding your surgery During your hospital stay your medical team will be available to discuss anything mentioned in this booklet or to answer any other queries you may have Before you leave the hospital you will be given contact details of the relevant team members After discharge from hospital you can expect to receive a phone call from an orthopaedic nurse enquiring after your wellbeing We look forward to meeting you soon 36 The knee area will be sore after the operation If you are in pain it is important to tell staff so that medications can be given Pain will improve with time Rarely pain will be a long term problem but may be due to altered leg length or any other complications listed or sometimes for no obvious reason Bleeding This is usually small and can be stopped during the operation However patients with large amounts of blood loss may need a blood transfusion or iron tablets Sometimes a blood clot may form or a large bruise may be noticed at the wound site which may become painful and require surgery to remove it Deep Vein Thrombosis DVT A DVT is a blood clot in the vein This may present as red painful and swollen legs usually The risks of a DVT are greater after any surgery and especially bone surgery Although not a problem themselves a DVT can pass in the blood stream and be deposited in the lungs a pulmonary embolism PE This is a very serious condition which affects your breathing 37
Guidelines for Patients Having Total or Partial Knee Replacements Your consultant will prescribe medication to limit the risk of a DVT forming Starting to walk and mobilising after surgery is one of the best ways to prevent clots from forming Knee Stiffness Knee stiffness may occur after the operation especially if the knee is stiff before the surgery Manipulation of the joint under general anaesthetic may be necessary Prosthesis Wear and Loosening With modern techniques and new implants knee replacements last many years In some cases however they fail sooner The reason is often unknown Wear may contribute to loosening Loosening may cause pain and if loosening is significant a second joint replacement may be required This operation is significantly more complicated than the original joint replacement Infection Antibiotics are given just before and after the operation and the procedure will be performed in an operating theatre with sterile equipment Despite this infection may still occur The wound site may become red hot and painful There may also be a discharge of fluid or pus This is usually treated with antibiotics and an operation to wash out the joint may be necessary In rare cases the implants may be removed and replaced at a later date The infection can sometimes lead to sepsis blood infection and strong antibiotics may be required To prevent such infections persons with a joint replacement are generally given antibiotics with extensive dental procedures urinary tract infections or surgery as well as before other types of surgery If an infection occurs anywhere in the body it must be treated promptly with antibiotics 38 Guidelines for Patients Having Total or Partial Knee Replacements Blood Fat Embolism PE A PE pulmonary embolism is a consequence of DVT deep vein thrombosis PE may occur if the clot detaches from the vein and travels to the lung and can make breathing difficult A PE can be treated with blood thinning medication but can also be fatal Joint Dislocation If this occurs the joint can usually be put back into place without the need for surgery Sometimes this is not possible and an operation is required followed by application of a knee brace Nerve Damage Rarely nerves in the vicinity of the knee joint are stretched or damaged during the operation a neuropraxia This is often only noticed upon returning to the ward where the patient may complain of altered sensation in the foot or in more severe cases inability to move their foot outwards Changes in sensation to the outer half of the knee may be normal Every effort is made to prevent this however damage to the small nerves of the knee is a risk This may cause temporary or permanent altered sensation around the knee Total knee replacement surgery is done under tourniquet where a blood pressure cuff is applied to your leg and occasionally a nerve by the side of the knee can get damaged the peroneal nerve which may cause temporary or permanent weakness or altered sensation of the lower leg Fortunately the majority of these neuropraxias resolve over a period of time sometimes months In a very small minority the damage may be permanent 39
Guidelines for Patients Having Total or Partial Knee Replacements Guidelines for Patients Having Total or Partial Knee Replacements Heterotropic Ossification There is a small risk of developing ossification or calcification in the muscle tissue around the knee after surgery In the majority of cases this involves small islands of bone that do not cause any functional restriction and are only noticeable on x rays Rarely in less than 1 of cases there may be more extensive ossification that may cause stiffness and pain This can be corrected by surgical removal but only after 12 months have passed since the surgery Blood Vessel Damage The vessels at the back of the knee may rarely be damaged and may require further surgery Stroke CVA Sudden Death Bone Damage This is a very rare complication that can occur after any major surgery and from any of the above A bone may be broken when the prosthesis replaced knee joint is inserted This may require fixation either at the time or at a later operation Periprosthetic Fracture This complication can occur after a knee replacement if the bone is weak especially in the first two months after surgery Sometimes it is caused by a fall or stumble Periprosthetic femoral fracture causes thigh pain with weight bearing and may cause shortening and rotation of the limb 40 41
