The Bony Resection Accuracy with Patient-Specific Instruments during Total Knee Arthroplasty: A Retrospective Case Series Study

Figure 7

Differences in osteotomy at each anatomical site. (a) The difference of osteotomy was calculated by subtracting the planned osteotomy amount from the actual osteotomy amount. Negative numbers indicate inadequate osteotomy (undercut), while positive numbers mean excessive osteotomy (overcut). (b) The magnitude of the difference is measured in absolute value. Abbreviations: DMFC=distal medial femoral condyle; DLFC=distal lateral femoral condyle; PMFC=posterior medial femoral condyle; PLFC=posterior lateral femoral condyle; AFC=anterior femoral condyle; MTP=medial tibial plateau; LTP=lateral tibial plateau.
