Abstract
Understanding of mechanical factors influencing knee joint loading is crucial for insight into OA progression and development of prevention and treatment strategies. High tibial osteotomy (HTO) changes knee alignment. Forces and moments should also be altered and reduce loading on one compartment.
15 subjects undergoing high tibial osteotomy were enrolled in the study. Markers were placed on prominent anatomical landmarks to indicate 12 body segments. Three dimensional positions of each marker were calculated using fourteen cameras (Eagle 8 mm, Motion Analysis Corp.) recording at 100Hz and a motion analysis system (EvaRT4.6, Motion Analysis Corp.). Three-dimensional external moments and inter-segmental joint forces were calculated using inverse dynamics in the Kintrak™ software. Kinematic and kinetic data from
