Sampling MethodNon-Probability Sample
Study Population

All patients over 21 years of age who required a primary robotic-arm assisted medial unicompartmental arthroplasty.

You may qualify if:

  • All patients over 21 years of age who underwent primary robotic-arm assisted unicompartmental arthroplasty and received a medial MCK onlay implant and are at least 24 months post-operative.
  • Patient has signed an IRB approved Informed Consent Form or with IRB approved waiver of written consent, patient has verbally consented to study participations.
  • Patient willing to comply with follow up.

You may not qualify if:

  • Patient will be excluded from participation in the study if they are cognitively unable to answer questions related to their index procedure and health related quality of life forms.
  • Patient had active infection
  • Medial MCK onlay implants were implanted without bone cement
  • Patients did not have sufficient bone stock to allow for insertion and fixation of components
  • Patient did not have sufficient soft tissue integrity to allow for stability
  • Patient had a neurological or muscular deformity that did not allow for control of the knee.
