Rotaglide total knee arthroplasty: a long-term follow-up study.

Background: Mobile-bearing knee designs represent an alternative to conventional fixed-bearing implants in total knee arthroplasty. The purpose of this study was to determine the clinical results of a mobile-bearing knee implant.

Methods: From 1990 to 1998, 326 primary consecutive mobile-bearing total knee prostheses were implanted in 260 patients who had a mean age and standard deviation of 66.

The role of timing of tourniquet release and cementing on perioperative blood loss in total knee replacement.

The purpose of our study is to estimate the effect of tourniquet release and cementing in perioperative blood loss associated with total knee arthroplasty. Eighty patients were randomly allocated into two equal groups concerning the timing of tourniquet release. Group A: patients with tourniquet release and haemostasis before wound closure and group B: patients with tourniquet release after skin closure and compressive bandaging.
