A 31-year-old male patient was a candidate for knee replacement surgery following a previous fracture. Due to the defect in the lateral femoral condyle, it was not possible to use standard prostheses for the joint replacement. Based on the physician’s recommendation, the lateral condyle was reconstructed using a patient-specific implant tailored to the patient’s anatomy, and the knee replacement surgery was successfully performed using conventional prostheses.

Pre-operative simulation and planning

After obtaining radiology and CT images and planning according to the physician’s treatment plan, a custom Cone Half was designed to reconstruct the bone defect.

After planning and design, the custom-made implant was manufactured using 3D printing.

Images after surgery

Based on the preoperative planning, the prosthesis was placed 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.The knee replacement surgery was successfully performed, and fortunately, after 12 months, the patient is in excellent condition.
