High Rate of Early Revision After Custom-Made Unicondylar Knee Arthroplasty.

Background: There has been a recent interest in custom-made partial knee arthroplasties to provide patient-specific instrumentation and better fit of the prosthesis. While unicondylar knee arthroplasties (UKAs) have demonstrated good outcomes and durable results in many studies, there is little evidence on outcomes of these custom-made implants.

Methods: We performed a retrospective review of all custom-made UKAs performed at our institution by one surgeon from 2008 to 2015.
