clinical applications, including pre-operative planning, 11 – 13 manufacturing of patient-specific instrumentation (PSI), 14 – 16 and the manufacture of case-specific implants (e.g. plates and arthroplasty components). 17 – 19 Overall, there

patient-specific instrumentation (PSI), represents one possible approach to achieve this goal. This review article explores the use of PSI for UKA, including our experience with this technology in the MSk Lab at Imperial College London. Additive

, 3D printing has mainly been utilized in pre-operative planning and 3D patient-specific instrumentation (PSI). One of the key focuses in paediatric orthopaedic practice is corrective limb deformity. With increasing accessibility to 3D printing, this

  • Computer-assisted orthopaedic surgery was born in the 1990s. Nowadays, computer-assisted orthopaedic surgery is used for transpedicular screw fixation and for total knee arthroplasty.

  • Patient-specific instrumentation is one type of computer-assisted surgery based on volumetric images, such as computed tomography or magnetic resonance imaging.

  • In this article, possible applications of patient-specific instruments in paediatric orthopaedics are described. The use of patient-specific instrumentation for the correction of cubitus varus is given as an example with complex osteotomy. Another application for tarsal coalition resection is shown.

  • A last example of using patient-specific instrumentation for both tumour resection and allograft reconstruction is illustrated.

  • Patient-specific instruments based on computed tomography of the bone can increase peri-operative accuracy and decrease operative time. They are very helpful for the surgeon. Other applications are possible and will be probably developed in the future.
