Outcome Measures

Primary Outcomes (6)

  • Ligament tension

    Measure the medial and lateral ligament tension of the operative knee at different flexion angle

    During operation

  • Pre-operative knee function

    Assess the knee function using AKS (The American knee society, 0\~200, higher scores mean a better outcome) scale before operation

    1day before operation

  • Post-operative knee function

    Assess the knee function using AKS scale at the 3rd day post-operation

    The 3rd day after operation

  • Post-operative knee function

    Assess the knee function using AKS scale at the 6th week post-operation

    The 6th week after operation

  • Post-operative knee function

    Assess the knee function using AKS scale at the 3rd month post-operation

    The 3rd month after operation

  • Post-operative knee function

    Assess the knee function using AKS scale at the 12th month post-operation

    The 12th month after operation

Secondary Outcomes (6)

  • Pre-operative infection test

    1day before operation

  • Pre-operative infection test

    1day before operation

  • Pre-operative infection test

    1day before operation

  • Post-operative infection test

    The 1st day after operation

  • Post-operative infection test

    The 1st day after operation

  • +1 more secondary outcomes

Study Arms (1)

Ligament tension measurement group

All participants will receive ligament tension measurement by the tension device during operation

Device: A gap plate with the function of knee joint pressure detection

Interventions

A gap plate can measure knee joint pressure by tension sensor. This is a part of routine medical care.

Ligament tension measurement group
