Use of Navigation in Total Knee Replacement with Special Emphasis on Rotating Platform Knee

Dr. Praveen. S. Battepati, Dr. Manish P Samson, Dr. Thomas Chandy

Abstract :

Background: Malalignment during knee arthroplasty leads to Polyethylene overload, Bone overload, soft tissue imbalance and patellar maltracking. Malaligment can be Medial/Lateral, Anterior /Posterior, Proximal/Distal placement of implants or Rotational. This study was performed to determine whether Computer Assisted Navigation Surgery (C.A.N.S) significantly improves the Implant Placement. Materials and Methods: This is both a Retrospective and Prospective Study. Duration of Study : 14months, Number of Patients: 21 Results: The mean preoperative FTA was – 6.7º (0º to –19.6º) in the conventional group where as in the Navigation group it was –6.71º (0º to –23.5º). The mean postoperative FTA was 4.56º (1.0º to 9.4º) in the conventional group where as in the Navigation group it was 4.86º (1º to 13.7º). Conclusion: In this study we have found a statistically significant difference in the placement of Tibial Tray in the frontal plane between the two groups, but unable to conclude which method is more advantageous. This is because we cannot compare our study with that of others.
