Abstract
This disclosure is directed to tibial cutting guide assemblies for preparing a tibia for receiving an arthroplasty implant. Exemplary tibial cutting guide assemblies may include a tibial cutting block for making precise cuts in the tibia, and a slope setting pin for establishing a patient specific tibial slope. The tibial cutting guide assemblies allow for level resection while providing surgical control over internal/external rotation and varus/valgus alignment.
