Abstract: Aim: The main aim of this study is to radiologically assess the components alignment in various planes in total knee replacement and to assess its relationship to the functional outcome using the knee society score.
Materials and Methods: This hospital based prospective observational study of 30 patients was conducted in the department of Orthopaedics at Maharaja Agrasen Hospital, New Delhi on patients who underwent elective primary Total Knee Arthroplasty and the period of study being 24 months from June 2016 to May 2018. All patients were assessed clinically and functionally using the Knee Society Score pre and post operatively for a follow up period of 6 months.
Results: The mean coronal alignment and rotational alignment of femoral component in our study was 5.87 degrees and 2.99 degrees of external rotation respectively. The mean tibial component coronal and rotational alignment in our study was 90 degrees and 17.77 degrees respectively. The mean preoperative flexion of 81.33 degrees increased to 113.5 degrees postoperatively with a significant p value of <0.001. There was significant improvement of Knee Clinical Score and Knee Functional Score following Total Knee Arthroplasty with a p value <0.001.
Conclusion: In our study the use of conventional extra medullary guide for tibia and intramedullary guide for femur to align a total knee replacement provided acceptable alignment and gives a good functional outcome as measured by knee society score.
