Clinical Outcomes of Joint Arthroplasty

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.

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.
