Development of a robotic device for Anterior Cruciate Ligament (ACL) reconstruction surgery

Up to 25% of patients who undergo Anterior Cruciate Ligament (ACL) reconstruction surgery experience unsatisfactory functional scores [1]. The placement of bone tunnels plays a critical role in determining postoperative outcomes. This study aims to utilise findings from biomechanical studies on the load-bearing functions of the fibres at the tibial and femoral attachments of the ACL [1,2] to guide accurate drilling of the bone tunnel, ensuring optimal surgical outcomes. The project aims to use CT/MRI images of the knee joint for geometrical analysis of distal femoral and proximal tibial geometry, as well as extraction of anatomical features. This analysis will inform the planning of tunnel placement for the reconstructed ACL. Additionally, it aims to design a robotic device capable of executing the surgical plan and tensioning the artificial graft with high precision. A physical prototype of the robot is envisaged, and tests will be carried out using artificial models of the knee joint. This work will require a range of skills, including software development, mechanical design, kinematic analysis and control of robotic systems, and interaction with a wide range of disciplines, including orthopaedic surgeons and anatomists.

This work will be conducted at the School of Physics, Engineering, and Technology (PET), with access to state-of-the-art laboratories and equipment for robotic biomechanical testing and manipulation. 

Candidates should possess (or expect to obtain) a minimum of a UK upper second-class honours degree (2.1) or its equivalent in Electrical, Electronic, Control, Mechanical Engineering, Computer Science, or a closely related subject. Preference will be given to candidates holding a Master’s degree in the aforementioned areas. Applications will be evaluated on a competitive basis, taking into consideration the candidate’s qualifications, skills, experience, and interests.
