FIELD: medicine.
SUBSTANCE: invention refers to medicine. A set of tibial trials used during a knee arthroplasty, comprising a distal femur and proximal tibia, accommodates a first tibial trial for positioning in relation to the distal femur and first incised surface on the proximal tibia and a second tibial trial for positioning in relation to the distal femur and first incised surface on the proximal tibia. The first tibial trial at least partially models a first tibial graft implanted on the first incised surface of the proximal tibia. The second tibial trial at least partially models the first tibial graft implanted on the second incised surface of the proximal tibia.
EFFECT: invention allows to simplify knee joint manipulations, including those involving the preservation of both crucial ligaments, while maintaining, and though improving safety, accuracy and/or effectiveness of the above manipulations.
