Abstract

PURPOSE
To investigate the improvement in balance after TKA and the difference of balance between posterior cruciate ligament retaining & posterior cruciate ligament substituting prostheses.
MATERIALS AND METHODS
Twenty-six patients scheduled to undergo TKA were randomly assigned to receive either PCL-retaining or PCL-substituting prosthesis. The balance of the subjects were checked prior to and at least six months after the operation by computerized dynamic posturography. We investigated whether the balance improve and the difference of change between the implants.
RESULTS
Patients showed significantly the improvement of balance by the knee proprioception after TKA (p<0.05) during intercepting visual compensation and the more HSS Knee score improve, the more its balance improve (p<0.05, r=0.667). But the difference of balance between the implants was not detected significantly (p>0.05).
CONCLUSION
The balance by the proprioception improves as the HSS Knee Score increases after TKA, and does not show the difference between the implants.
