Many Possible: There are quite a few possible complication from a knee arthroplasty. This is best discussed with your surgeon. But in general, for the right patient, it is a good procedure.

Rare Things !: Complications are rare. These include the usual players like infection, blood loss, and pain. Special issues include blood clots, which can be reduced by strong anti-coagulant medications, tight stockings and machines that keep blood flowing. Typically my biggest concern is making sure my patients work hard on range of motion! if not the knee might not bend all the way. Work really hard !

Major: complications include the risk of bleeding infection blood clots or the need for future surgery these risks are all relatively low
