No detaild study has been performed to assess the difference in cement volume between the lateral and medial condyles. In this study, the area of the cement layer was measured by means of NIH image and the difference in the cement volume between the condyles was quantitatively investigated. Bone quality change one year after TKA was also inquired. The results showed that more cement was significantly inserted into the lateral tibial condyle than the medial condyle in cemented total knee arthroplasty, and bone quality along the medial edge of the medial tibial condyle was found to have deteriorated at sgort-team follow-up after total knee arthroplasty.
