Photographs show (A) the complementary prosthesis template to measure the accuracy of the bone resection near the joints in Patient 7 and (B) the precise fitting of the prosthesis to the small residual bone fragments in Patient 4. We preserve the soft tissue and ligament attachments, in particular at the posterior intercondylar notch where the middle genicular artery enters and supplies the remaining distal femoral epiphysis [13].
