Abstract

Background Preoperative templating is the gold standard in planning elective total knee arthroplasty. This retrospective study analyses preoperative templating by using two different calibration devices. Methods Preoperative radiographic templating with TraumaCad using two different calibration devices was performed in 231 patients. Results Overall, 60.6% (n = 140) did not match and 39.4% (n = 91) matched for tibial as well as femoral size. Group I showed significantly more combined matches as well as for just the size of the femoral component. Conclusions In this study, the KingMark calibration should be preferred to standardised ball markers.
