A 38-year-old male patient, following a previous fracture in the tibia and the non-union of the tibial bone, presented with a large bone defect in the proximal tibia and suffered from early osteoarthritis. He was a candidate for knee replacement surgery. Due to the presence of extensive bone defect, joint replacement was not feasible without the use of custom implants.
Pre-operative simulation and planning
After obtaining radiology and CT images and planning according to the physician’s treatment plan, a custom Cone was designed to reconstruct the bone defect.
After completing the planning and design, the custom-made implant was manufactured using 3D printing
Surgical images
Based on the preoperative simulation, the prosthesis was positioned in the desired location. To ensure proper placement of the prosthesis, a trial component was used during surgery, followed by the implantation of the main component in the patient.
