Technique and Results of Allograft Reconstruction in Revision Total Knee Arthroplasty

This study reports more than four years of experience with bone allografts used to reconstruct large uncontained defects in the femur and the tibia in patients requiring revision total knee arthroplasty. Nineteen allografts were used, 13 in the distal femur and six in the proximal tibia. The average follow-up period was 2.1 years. After these complex revision arthroplasties, the average knee score improved from 29 to 87 points. The average patient function score increased from 35 to 85 points. Bulk allografts are effective in the reconstruction of uncontained defects in revision total knee arthroplasty.
