Patient-specific guide systems and methods for performing bone resections for ankle arthroplasties comprises a bone guide body and a bone resection block. The bone guide body comprises a patient-specific surface for engaging a surface of a talus or a tibia, and a first pin hole and a first socket in the bone guide body. The bone resection block is removably insertable into the first socket, receives a first pin that can be inserted in the first pin hole, and includes a resection guide surface. The system further comprises a floating bone trial that attaches to the bone resection block via a floating bone guide. The floating bone trail receives a chamfer spacer and guide for further resecting the bone. The system further comprises a stylus for engagement with the resection guide surface to confirm resection depth. The bone guide body includes alignment pin and resection block snap lock features.
