Joint Line Restoration in a Contemporary Revision Knee System

J Knee SurgDOI: 10.1055/s-0034-1368144We investigated a new revision total knee arthroplasty device and associated instrumentation to determine if it could reduce intraoperative complexity and restore the joint line through the arc of motion. In a prospective multicenter study, a total of 95 consecutive patients undergoing a revision knee arthroplasty were evaluated. Medical history, functional health scores, and intraoperative data were collected. The joint line was restored to 28 mm ± 5 mm in full extension and 90-degree flexion. Significant improvements were noted in all functional and general health scores. The anatomic boss position may allow for a reduction in instrumentation, as the need for femoral offset adapters was limited. Joint line restoration with proper posterior condylar offset correlated with positive functional outcomes.[...]Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.Article in Thieme eJournals:Table of contents  |  Abstract  |  Full text
