    LITERATURE ARTICLE RECEIVED ENTITLED "NO DIFFERENCE IN ACCURACY BETWEEN PINLESS AND CONVENTIONAL COMPUTER-ASSISTED SURGERY IN TOTAL KNEE ARTHROPLASTY". LITERATURE ARTICLE "NO DIFFERENCE IN ACCURACY BETWEEN PINLESS AND CONVENTIONAL COMPUTER-ASSISTED SURGERY IN TOTAL KNEE ARTHROPLASTY" (2013) BY C. BAIER, G. MADERBACHER, H. R. SPRINGORUM, F. ZEMAN, W. FITZ, J. SCHAUMBURGER, J. GRIFKA, AND J. BECKMANN PUBLISHED BY KNEE SURGERY SPORTS TRAUMATOLOGICAL ARTHROSCOPY DOI: 10.1007/S00167-013-2430-2 WAS REVIEWED FOR MDR REPORTABILITY. THE ARTICLE PURPOSE: TO EVALUATE THE ACCURACY OF A SO-CALLED PINLESS CTFREE VERSION OF KNEE NAVIGATION (PINLESS CAS) ABANDONING THE REFERENCE PINS AND REDUCING THE NECESSARY WORKFLOW TO A MINIMUM. THE ARTICLE REPORTS: THIRTY-TWO CONSECUTIVE PATIENTS RECEIVED A STANDARD TOTAL KNEE ARTHROPLASTY (DEPUY, PFC, JOHNSON AND JOHNSON) ASSISTED BY CT-FREE CAS (BRAINLAB, FELDKIRCHEN, GERMANY). THE OPERATIONS WERE PERFORMED BY TWO EXPERIENCED SURGEONS ([500 TKA) VIA A STANDARD MEDIAL PARAPATELLAR APPROACH WITH TOURNIQUET, FULLY CEMENTED IN SPINAL ANAESTHESIA. THE PATIENT POPULATION CONSISTED OF 30 PATIENTS, 21 WOMEN AND 9 MEN WITH A MEAN AGE OF 67 YEARS. THE USE OF CAS DURING TKA HAS PROVEN SIGNIFICANT REDUCTION IN OUTLIERS CONCERNING ALIGNMENT OF THE LIMB AND COMPONENT POSITION. OPPONENTS OF CAS OFTEN CLAIM THE LENGTHENING OF THE SURGICAL TIME AND THE ADDITIONAL TRAUMA AND RISKS DUE TO THE REQUIRED PINS. IN CLINICAL ROUTINE, PINLESS CAS COULD COMPRISE THE ADVANTAGES OF CAS WHILE LEAVING THE DISADVANTAGES ASIDE. IT REDUCES SURGICAL TIME AND AVOIDS PROCEDURE-ASSOCIATED COMPLICATIONS ASSOCIATED WITH THE TRACKING PINS OF CONVENTIONAL NAVIGATION SYSTEMS. IN THE IMMEDIATE POSTOPERATIVE PERIOD, ONE WOUND DEHISCENCE REQUIRED DEBRIDEMENT AND SECONDARY SUTURE ON DAY 9 AFTER THE TKA. NO OTHER REVISION WAS NECESSARY, AND OTHER COMPLICATIONS SUCH AS INFECTION, FRACTURES, DVT OR ELSE DID NOT OCCUR. CEMENT USAGE AND PATELLA RESURFACING WAS NOT MENTIONED IN THIS ARTICLE. DEPUY PRODUCTS INVOLVED: UNKNOWN DEPUY KNEE SYSTEM.
