Abstract
Total knee replacement is a surgical procedure for treatment of knee Osteoarthritis, Rheumatoid arthritis and posttraumatic arthritis. The main goals of TKR are relieve the pain, restore function, mobility and restore normal limb alignment for the patients. The aim of the study to investigate the gait dynamic improvements following TKR surgery by compare the dynamic parameter pre-operative and post-operative and then comparing the results with the normal gait parameters. The gait analysis was performed on five patients before and after they underwent unilateral TKR surgery. After three months from the total knee replacement there was a remarked increase in the function and decrease in pain. The varus and valgus malalignment will be return to normal alignment after operation, which is one of the main goals of the TKR. Post-operative cadence is higher than pre-operative for four patients, post-operative speed is faster than pre-operative for four patients and post-operative stride length is larger than pre-operative for four patients. The patients continue to walk with significant gait abnormalities by examining the kinetics and the kinematics of the operated limb, the results show the knee function not fully restored three months after unilateraL TKR surgery.
