Product description
Eius Unicompartmental Knee System Stryker Howmedica Osteonics Corp. Howmedica International S. de R.L., Raheen Business Park, Limerick, Ireland. Intended for use in Unicompartmental Knee Arthroplasty (UKA). Surgeon users have identified the following potential advantages of UKA procedures versus Total Knee Arthroplasty procedures generally: conservation of the opposite compartment, preservation of ligaments and patellofemoral articulation, reduced loss of bone stock and lower implant cost. The EIUS UKA is a Resurfacing device that requires the removal of a thin condylar cross-section intended to replace the diseased cartilage only. This allows the surgeon to conserve good quality subchondral bone.
