Digital templating of rotating hinge revision and primary total knee arthroplasty.Preoperative digital templating in total knee arthroplastiy (TKA) is useful in predicting implant size, the level of bone resections and the need for special implants.  Two observers with different experience levels templated 40 cases which received TKA and R-TKA using digital planning on standard preoperative x-rays.  The accuracy in predicting the correct implant size in revision TKA varied from 67,9% to 82,1% depending on the training level of the observer.  The coefficient indicates a substantial agreement in between the two observers in templating revision TKA.
