A device for measuring displacement of the tibia in relation to the femur in response to an applied force or torque on the tibia. A first shaft is tiltable about a first axis close to the ankle and approximately parallel to the coronal plane of the patient's body. A second shaft is connected to the first shaft and is rotatable about a second axis perpendicular to the first axis, and is close to the ankle and approximately parallel to the tibia. A foot support platform is mounted on the second shaft, the foot support platform being configured for attachment of the foot at a fixed position. A displacement test device is provided for applying forces to the tibia and measuring the shift or displacement of the proximal tibia relative to the distal femur.
