Three-dimensional gait analysis and case-control follow-up observation following total knee replacement / 中国组织工程研究

ABSTRACT

BACKGROUND:Evaluation plan for the neuro-musculo-skeletal system model and motor function was little.However,the three-dimensional gait analysis can transfer qualitative analysis and object description which widely used in orthopedics and rehabilitation medicine to quantitative evaluation with more objective and precise.OBJECTIVE:To evaluate gait kinematics and kinetic changes after total knee replacement based on 12 months follow up using three-dimensional gait analysis.DESIGN,TIME AND SETTING:The comparative observation and case-control study was performed in the Gait Analysis Room of the Department of Rehabilitation Medicine in the Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University from January 2007 to May 2008.PARTICIPANTS:Ten patients with knee osteoarthritis following total knee replacement were chosen as treatment group;concurrently,ten patients whose baseline data were matched with the treatment group without problems in nerve,muscle,skeletal system and equilibrium were selected as the control group.METHODS:Ten patients in the treatment group underwent rehabilitation training,then compared time-distance,kinematic,and mechanical parameters which were measured at 3,6,12 months after total knee replacement with the control group.MAIN OUTCOME MEASURES:Time-distance parameter,kinematic parameter,mechanical parameter and knee functional scores.RESULTS:Pace,step frequency,gait speed,and time of injured leg standing were notably decreased,while time of uninjured leg standing,duration of gait cycle were obvious prolonged compared with the control group(P
