Alexandria, Virginia 22306


Purpose:

The main purpose of this study is to determine whether the surgical time required for primary total knee arthroplasty is significantly less when performed with Customized Patient Instrumentation (CPI) than with conventional instrumentation. Each case will be recorded by video camera, in order to time the length of surgery and each surgical step. The number of surgical trays required for each case will be recorded. As an additional endpoint, the investigators will measure limb and component alignment on x-rays to determine if these two methods achieve equivalent alignment results. The thickness of bone cuts will be compared to the surgical plan and to each other. The primary hypothesis is that the use of customized patient instrumentation will reduce the operative time required for total knee arthroplasty.


Criteria:

Inclusion Criteria: - Patient requires unilateral primary total knee arthroplasty Exclusion Criteria: - Body mass index greater than 41 - Previous ipsilateral hip or ankle replacement - Knee flexion contracture greater than 20 degrees
