Abstract
The use of three-dimensional (3D) printing has seen a vast expansion over recent years, with an increased application for its use in orthopaedics. This report details the use of 3D printing technology to aid in the treatment of a medial femoral condyle osteochondral defect in a 26-year-old female who had previously undergone a failed autograft procedure. A preoperative computed tomography scan of the knee and chondral defect was used to generate a 3D printed, one-to-one scale replica of the distal femur. This replica was then used to size a patient-specific allograft plug for the osteochondral transplantation procedure. The patient recovered well, and 1 year postoperatively the allograft was well incorporated into the medial femoral condyle and healed. This report illustrates the advantages of using a 3D printed model to allow for tactile feedback and improved visualization that will allow for improved understanding of complex surgical procedures.
