The freeware HTO-Planner was developed at IRCCS  Istituto Ortopedico Rizzoli, Bologna, Italy, in the BIC laboratory under the project RF-2018-12368274 of the Italian Ministry of Health “Impact of high tibial osteotomy in preventing disease progression in medial knee osteoarthritis: quantifying the effects on cartilage and subchondral bone by using a combined biomechanical and medical imaging approach”.

What is HTO-Planner?

HTO-Planner is a freeware that supports surgeons in the accurate planning of High Tibial Osteotomy surgical treatments. 

HTO-Planner can import RX images (full leg weight-bearing , latero-lateral and Rosenberg) and CT images in DICOM format. 

The software allows an accurate semiautomatic evaluation of the skeletal deformities and offers a user-friendly interface to plan the personalised desired correction. 
 

How does HTO-Planner works?

The user is asked to identify some relevant skeletal landmarks or features on the RX images of the patient. From these points, anatomical and mechanical segmental axes are automatically generated, together with measurements of the following angles that are needed to properly characterise the skeletal deformities.

The user can then plan the optimal osteotomy angle to reproduce in the surgical theatre.
