Patient Education: Unicompartmental Knee Replacement
EIUS® Unicompartmental Knee Replacement System
The EIUS® Unicompartmental Knee Replacement System provides a bone preserving, resurfacing approach to Uni Knees that completely eliminates the need to invade or ream into the intramedullary canal. This results in a minimally invasive procedure with potential to allow patients to quickly get back on their feet and back into life.
Designed to Meet 6 Key Objectives
Resurfacing technique with no large femoral bone cuts
Restore the anatomic joint line
Preserve bone stock
Minimum replacement of the damaged cartilage surfaces
Preserve ligaments, opposite compartment, and patello-femoral joint providing natural motion and a more normal feeling knee 3,4,5
Minimizes Surgery, Maximizes Mobility
No quadriceps incision-potential for less pain and faster recovery
Outpatient or shorter hospitalization compared to TKR–averaging one to two days9 hospital stay.
Faster rehabilitation 9,10 – some patients may resume activities like golf as early as six weeks post-operative
No patella eversion or resurfacing required
