Three-Dimensional Bioprinting in Orthopaedics.

Three-dimensional (3D)-printing technology has evolved dramatically in the last 30 years, from large machines with poor resolution to those with micron-level capabilities that sit on a desktop. This technology is being utilized in numerous medical applications, particularly in orthopaedic surgery. Over the past decade, technological advances have allowed for the application of this technology to the field of tissue engineering through the process of 3D bioprinting. Of interest to orthopaedic surgeons, active areas of research utilizing this technology involve the bioprinting of articular cartilage, bone, menisci, and intervertebral discs.
