Overview

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.

Outcomes

Primary Outcomes

single limb standing balance

migration distance of center of pressure while single limb standing was recorded through balance performance monitoring

Time frame: from issuing admision paper before the surgery up to 4 weeks, average time of this measurement is 2 weeks

single limb standing balance

migration distance of center of pressure while single limb standing was recorded through balance performance monitoring

Time frame: from the surgery until the time in which patient shows the same pain score as the pre-operation pain score up to the post-operative 4 weeks, average time of this measurement is post-operative 2 weeks

single limb standing balance

migration distance of center of pressure while single limb standing was recorded through balance performance monitoring

Time frame: post-operative 6 months

single limb standing balance

migration distance of center of pressure while single limb standing was recorded through balance performance monitoring

Time frame: post-operative 12 months

Secondary Outcomes

balance index

balance index, calculated ratio from the deviated distance and time from the neutral point, was collected by using the Biodex machine
