PERIPROSTHETIC KNEE INFECTIONS TREATED BY COMPUTED ASSISTED GUIDANCE (CAS) REVISIONS IN A ONE-STAGE PROCEDURE: A SERIES OF 41 PATIENTS

To evaluate a innovate one stage procedure of the PJI knee treatment using computed assisted guidance. Our objectives; to increase the functional results by optimizing the anatomical joint reconstruction and to verifie if CAS help to simplifie and standardize these complex surgeriesIt's a prospective, single surgeon study. Since septembre 2011, 41 patients treated for chronic knee PJI in a one stage revision (one of them had a ipsilateral chronic knee arthritis). For all of them, a computed assisted guidance, the ExactechGPS® system was used. This system offers the possibility to define specific profiles to performe primary TKA surgeries. A personnalized profile of revision was created.All surgeries were performed with the same protocole; independently of the type of germ, with no use of tourniquet, no drainage by performing the same debridement procedure step by step and by using the same knee components27 males, 14 female with 26 PJI of primary TKA, one infected unicompartimental prosthesis and 15 PJI o...
