A Prospective, Multi-Center Study to Evaluate the ConforMIS iUni® G2 Unicompartmental Knee Resurfacing Device

Study is prospective and multi-center. Study will include 100 to 200 patients across up to 20
sites.The study sites will be located in the United States.The study objective is to evaluate
the safety and performance of the ConforMIS iUni® Unicompartmental Knee Resurfacing Device in
patients with single compartment osteoarthritis.

The iUni G2 Unicompartmental Resurfacing Device (iUni) is an FDA cleared and CE Marked
implant designed for patients with damage isolated to either the medial or lateral
tibiofemoral compartment of the knee. The study subjects will be followed for 10 years post
implant. The study objective is to evaluate the safety and performance of the ConforMIS iUni®
Unicompartmental Knee Resurfacing Device in patients with single compartment osteoarthritis.
The iUni is a patient-specific unicompartmental resurfacing device designed from the
patient's unique anatomy using proprietary software which interprets data from the patient's
CT scan. The patient matched implant design is then coupled with unique patient-matched
disposable instrumentation designed using the same CT data and software. The follow-up visit
schedule will include visits at 6 weeks, 6 months (optional), 1 year, 2 years, 5 years and 10
years post implant.The remaining follow-up data collected at years 3, 4, 6, 7, 8, and 9 may
be collected via phone call/email and does not require a subject visit to the site.The study
sites will be located in the United States.
