Official Title
-----------------
Clinical Outcomes of Joint Arthroplasty

Conditions
-----------------
Osteoarthritis, Knee

Intervention / Treatment
-----------------
* Device: Robotic-arm assisted partial knee arthroplasty


Participation Criteria
=================
Eligibility Criteria
-----------------
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.
