Outcome Measures

Primary Outcomes (1)

  • Adductor strengths

    Adductor muscle strength is measured with a sphygmomanometer. Patients are instructed to squeeze a blod pressure cuff, already inflated to 40 mm Hg, between their extended knees. The maximal sustained pressure is taken as the baseline adductor strength.

    pre operative, 30 minutes before start surgery
