Researchers from Georgia, U.S.A, examined the alignment and accuracy of placement of knee replacement prostheses using 3D-printed patient-specific cutting jigs to implant Conformis custom-made knee replacements. The authors showed that ‘perfect’ alignment was achieved in 53 out of 63 knees studied, with the remaining 10 patients having alignment within ±2° of perfect. The authors highlight that these results are as good if not better than the best results published using CAS (computer-assisted surgery), such as ‘computer navigation’.
