A good outcome after arthroplasty depends on proper determination of the indications for surgery, good operative technique, and – especially important – proper postoperative treatment and medical rehabilitation. The aim of medical rehabilitation is to restore mobility to the highest possible degree and recover full muscular control of the operated knee: in other words, to restore normal static and dynamic function of the joint and the entire leg. This study presents a model of postoperative management and rehabilitation after total knee arthroplasty, based on a review of the current literature and the authors’ own clinical experience with 753 arthroplasties performed in 665 patients during the period 1996-2003.
