Brief summary

It was well known that total knee arthroplasty could improve the previously impaired proprioception in degenerative osteoarthritis. Most current researches have been focused on the change of the proprioception. However, the evaluation of the proprioception is based on the surrogated end. Double or single limb standing balance is considered functional scale. It is very important view for the prevention of slipping down injury in evidence-based approaches for knee osteoarthritis. Unfortunately, few study have been performed for figuring proprioceptive change after surgery out. Considering the similarity between the proprioception and the standing balance and reported positive result in proprioception after total knee arthroplasty, the investigators supposed that total knee arthroplasty might give an influence on the recovery of single limb standing balance.

Design outcomes

Primary

Measure	Time frame	Description
single limb standing balance	from issuing admision paper before the surgery up to 4 weeks, average time of this measurement is 2 weeks	migration distance of center of pressure while single limb standing was recorded through balance performance monitoring

Secondary

Measure	Time frame	Description
balance index	from issuing admision paper before the surgery up to 4 weeks, average time of this measurement is 2 weeks	balance index, calculated ratio from the deviated distance and time from the neutral point, was collected by using the Biodex machine
