About this study

The purpose of this study is to document the clinical outcomes of partial knee replacement surgery using robotic-arm assisted knee joint surgery at 3 weeks, 6 weeks, 12 weeks, 6 months, 1 year, 2 years, 5 years and 10 years post operative.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • All patients over 21 years of age who require a primary robotic-arm assisted unicompartmental knee arthroplasty or bicompartmental knee arthroplasty. These patients will have failed non-operative management of their joint disease and are candidates for partial joint replacement because of pain and stiffness that interferes with their performances or normal daily activities.

Exclusion criteria

  • Patient had an active infection
  • Onlay implants were implanted without bone cement
  • Patient does not have enough bone stock to allow for insertion and fixation of the components
  • Patient does not have sufficient soft tissue integrity to allow for stability
  • Patient has a neurological or muscular deformity that did not allow for control of the knee
  • Patient will be excluded from participation in the study if they are cognitively unable to answer study questions
  • Pregnant women are excluded.

Treatment and study plan

Robotic-arm assisted partial knee arthroplasty

Device

Robotic-arm assisted medial unicompartmental knee arthroplasty, lateral unicompartmental knee arthroplasty, bicompartmental knee arthroplasty, patellofemoral knee arthroplasty implants. A robotic arm assisted unicompartmental or bicompartmental knee arthroplasty procedure to replace the medial or lateral and /or patellofemoral compartments of the knee.

Primary outcomes

  1. % of patients with Revisions

    Time frame: 10 years after surgery

    To assess the revision rate of this patient population

Secondary outcomes

  1. Patient satisfaction rate

    Time frame: 10 years after surgery

    To assess level of patient satisfaction using a questionnaire.
