Staged Versus Simultaneous Bilateral Knee Arthroplasty
Staged Versus Simultaneous Bilateral Knee Arthroplasty
The purpose of this study is to assist surgeons and patients in answering the question
 "Should I have both knees replaced at the same time, or should I just do one and wait to do
 the second one?"
This is a multi-center randomized controlled trial of 224 patients in order to clearly
 delineate differences in post-operative outcomes and the trajectory of recovery between
 simultaneous and staged bilateral KA. The primary outcome measure is difference in generic
 health related quality of life between the two groups measured 1 year following surgery.
 Secondary outcome measures include differences in joint specific scores, time off work,
 satisfaction and costs.

 This trial will inform patients and clinicians about differences in recovery, function and
 efficacy of the procedure to aid in the selection of treatment pathway to best suit the
 patient.
Inclusion Criteria:

 -  Patients considering bilateral knee arthroplasty

 -  Patients must sign the consent form

 -  Patients must be willing to complete the study questionnaires for the duration of the
 study

 Exclusion Criteria:

 -  Patients who require simultaneous bilateral knee replacement surgery in order to
 manage significant bilateral flexion or valgus knee contractures where staged
 procedures may result in suboptimal outcomes by increasing the risk of post-operative
 flexion contracture in the "first replaced" knee

 -  patients who are unable to complete the questionnaires
