Infection Prevention After TKA With or Without Vancomycin

Study Overview
=================
Brief Summary
-----------------
Prospective, Randomized, Double Blinded Trial Comparing Clinical, Radiological and Laboratory Outcomes in prevention of infection after Total Knee Arthroplasty With or Without Vancomycin.

Detailed Description
-----------------
Infection after surgery is one of the most common complication after total knee replacement. Our prospective randomized study is intended to show if addition of vancomycin to the joint before the wound closure will decrease infection after operation.

| Visual analog Scale | Pain Visual Analog Scale The pain VAS is a unidimensional measure of pain intensity. The most simple VAS is a straight horizontal line of fixed length, usually 100 mm. The ends are defined as the extreme limits of the parameter to be measured (symptom, pain, health)[8] orientated from the left (worst) to the right (best). | 6 weeks |
