1- How active can you be after the operation?
The answer to this lies within you. The more active you were before the hip got painful, the more active you are likely to be after. A positive outlook really helps. Your knee will be pain-free with a much better ranger of movement. Your muscles will be weak so physiotherapy will help.
2- When can I drive?
It is inadvisable to drive for 6 weeks after a joint replacement. Check with your insurance company.
3- How long will my new knee last?
Published survival figures for the AGC Knee Replacement suggest that at 12-15 years, 95-98% will still be functioning correctly.
4- What are the risks?
The risks of surgery are low. The most common complications are minor; superficial infection, blood clot (DVT), urinary or chest infection. These may prolong your stay in hospital by a few days. They will occur in 2-4% of cases. You will be given medication to prevent infection and DVT and helped by the physiotherapists to walk in the early post-surgical phase. There are more serious risks such as; stroke, heart attack and pulmonary embolus (lung blood clot). The risk here is very small, less than half of one percent (0.2-0.4%), but no major operation is risk free. Your decision whether or not to have your operation is a question of risk versus benefit.
