The Knee Society total knee arthroplasty roentgenographic evaluation and scoring system

A roentgenographic knee evaluation system endorsed by The Knee Society is included in this year's proceedings to encourage uniform reporting of the results of total knee arthroplasty. No rating system is ideal, but if many surgeons and centers use the same reporting system, then relative comparisons will at least become possible. Agreement on a new system by many experienced surgeons and institutions with a large clinical volume represents a sacrifice because old rating system data will have to be discarded.
