Computer Assisted Total Knee Replacement

2014-08-27 03:46:37 | BioPortfolio


The purpose of this study is to determine whether intraoperative computer-assisted navigation improves prosthetic implant positioning as compared to conventional intraoperatve instrumentation in Total Knee Arthroplasty (TKA).


Primary data to be obtained is to determine whether mechanical axis of the limb malignment differs between patients whom have computer-assisted TKA and those treated with conventional intraoperative instrumentation.

Three months after surgery follow-up radiographic data will provide evidence on the initial implant position as determined with a series of x-rays including: full length standing, standard AP weight bearing, lateral, patellar, kneelingfilm views and CT evaluation. In addition, a correlation betweeen the CT measures and the kneeling x-ray can be performed at this time. Clinical (Knee Scale Society, WOMAC, and SF-36) data will also be obtained at the three month interval.
