Changes of the Single Limb Standing Balance After Total Knee Arthroplasty in Degenerative Osteoarthritis

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.

Treatment and study plan

Primary outcomes

  1. single limb standing balance

    Time frame: 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

  2. single limb standing balance

    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

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

  3. single limb standing balance

    Time frame: post-operative 6 months

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

  4. single limb standing balance

    Time frame: post-operative 12 months

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

Secondary outcomes

  1. balance index

    Time frame: 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

  2. balance index

    Time frame: post-operative 6 months

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

  3. balance index

    Time frame: post-operative 12 months

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