An excellent article on AAHKS.org Do I need a jont replacement?
One of the best features of custom knee replacement is the ability to reliably correct deformity. By scanning the hip, knee and ankle, preoperatively, we can almost always get perfect alignment. Here is one of my patients who had knee replacements on both sides, before and 4 weeks after his surgery. This kind of result is now possible for almost any knee, no matter how bad the deformity.
