Case: We present the case of a 46-year-old patient with asymmetric deformity in the posterior tibial slope after previous high tibial osteotomy surgeries with the presence of a medial osteotomy plate. A customized cutting guide was designed to fit on the plate to perform a single surgery and avoid possible soft-tissue complications after multiple surgeries.
Conclusions: The presence of a previous internal fixation device may affect the manufacture of 3-dimensional cutting guides. However, in this case, the previously placed osteosynthesis plate was used as an aid for creating the guide.
