NCT01832272

Brief Summary

This study is aimed to determine the efficacy and the safety of the tourniquet reinflation after early tourniquet release in total knee arthroplasty, compared to the method of early deflation without reinflation. The investigators hypothesized that the reinflation after early release of the tourniquet would be effective in terms of improved visualization of the surgical field and decreased operation time and blood loss, whereas it would increase tourniquet-related complication due to longer tourniquet-use time.

Outcome Measures

Primary Outcomes (1)

  • Operation time

    Total time between initial skin incision and wound closure

    from skin incision to wound closure

Secondary Outcomes (12)

  • Tourniquet time

    total sum of time between inflation and deflation of tourniquet

  • Difficulty of the operation

    from skin incision to wound closure

  • Incidence of transfusion

    within 2weeks after surgery

  • Wound complications

    on the 2nd and 14th day after surgery

  • Thigh complications

    within 2 weeks

  • +7 more secondary outcomes

Study Arms (2)

Reinflation after early deflation

EXPERIMENTAL

The tourniquet is released after cement implant fixation, and then reinflated, once arterial bleeding was controlled (Reinflation after early tourniquet deflation).

Procedure: Reinflation after early tourniquet deflation

No reinflation after early deflation

NO INTERVENTION

The tourniquet is released after cement implant fixation, and remained deflated without reinflation, even after hemostasis.

Interventions

The tourniquet is released after cement implant fixation, and then reinflated, once arterial bleeding was controlled

Also known as: Reinflation after early tourniquet release
Reinflation after early deflation
