Abstract

BACKGROUND: Osteoarthritis is the most prevalent chronic joint disease affecting ambulation of a person. The incidence of osteoarthritis is rising because of the ageing population and the epidemic of obesity. Pain and loss of function are the main clinical features that lead to treatment. AIM AND OBJECTIVES: To assess the components alignment in total knee replacement done using traditional jigs which include Varus, valgus and rotational alignment of tibial and femoral components Posterior tibial slope and posterior condylar offset preoperatively and post operatively. To assess the relationship between components alignment and the functional outcome. MATERIALS AND METHODS: A prospective study was done between the period of September 2013 – May 2015. 15 patients who underwent total knee arthroplasty in Institute of Orthopaedics and Traumatology, Madras Medical College were assessed clinically, functionally and radiologically. The follow up period was at 3 months, 6 months. The study was conducted at the Institute of Orthopaedics, Madras Medical College , Chennai. RESULTS: - Intramedullary jig for femur gave satisfactory coronal plane alignment of the femoral component. - For rotational alignment of the femur in addition to the posterior condylar line, transepicondylar axis and whiteside line must also be compared for accurate rotational. - Extramedullary alignment jig for tibia provided satisfactory coronal plane alignment of the tibial component. CONCLUSION: It’s ideal to compare the position of the components with the anatomical landmark intraoperatively in addition to the jigs. When all the landmarks are used in total knee replacement using traditional jigs we can achieve proper component alignment.
