Fig. 3From: Accuracy, inter- and intrarater reliability, and user-experience of high tibial osteotomy angle measurements for preoperative planning: manual planning PACS versus semi-automatic software programsDeformity analysis and planned correction angle measurements utilising the semi-automatic software tools in TraumaCad®. The Knee Limb Alignment Analysis Tool was utilised to determine the mLDFA and mMPTA based on the centre of the hip, knee, and ankle (left). The High Tibial Osteotomy Tool was utilised to determine the size of the correction angle required to restore the mechanical leg axis (right). mLDFA = mechanical lateral distal femoral angle; mMPTA = mechanical medial proximal tibial angleBack to article page
