The purpose of this study was to compare total knee arthroplasties (TKA) to a group of control subjects to see if any balance deviations existed at 12-16 weeks post operatively. Ten normal and two TKA subjects (65-80 years of age) were evaluated with the NeuroCom Balance Master® 6.1 system The evaluation consisted of five tests that measured endsway, reaction times and weight bearing characteristics. Ten normal subjects as well as two TKA's took place in this study. The results showed that the TKA's had a decreased reaction time, increased sway and abnormal weight bearing characteristics. In conclusion we see that at this time frame the TKA has a decreased level of balance compared to the normal group.
