* Joint line restoration in a contemporary revision knee system.
- We 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.
