AN IN VIVO ANTHROPOMETRIC STUDY ON FEMORAL AND TIBIAL MORPHOLOGY AND COMPARISON WITH THREE DIFFERENT IMPLANT SYSTEMS IN INDIAN POPULATION: AN EFFECTIVE INDIGENOUS STUDY. “TRANSFORMATION FROM ACCURACY TO PRECISION IN TOTAL KNEE ARTHROPLASTY”

Background: Total Knee Arthroplasty is very successful procedure with almost 98% of successful outcomes. The ease of surgical techniques and wide range availability of Implants made this surgery very competent and encouraging. Most of the Implants have been studied and designed in various countries. In our study we measured our Indian Knees intra operatively and assessed the anthropometry of wide popular implant systems which are used across the world(SMITH & NEPHEW, DEPUY, ZIMMER). Materials and Methods: We studied 151 patients who underwent Total Knee Replacement in our hospital and measured intraoperatively the native anatomy measurements of femur and tibia of Indian Population and compared with the dimensions of Femoral and Tibial components of Femur and Tibia of Genesis II, SMITH & NEPHEW, DEPUY, ZIMMER implant system. Results: There was a huge variability between the patient anatomical parameters and the actual implant kept except for femur MCAP, LCAP, Tibia ML in Depuy. Conclusion: We conclude by saying that there is a significant mismatch of Measurements between the femur native human anatomy and components of Implant systems. Therefore there is a wide scope of generating the appropriateness of Implant designs and Dimensions according to Indian Native Human Anatomy in the field of Total Knee Arthroplasty.
