3-Dimensional Printed Models May Be a Useful Tool When Planning Revision Anterior Cruciate Ligament Reconstruction.

Purpose: To determine whether using 3-dimensional (3D)-printed models in addition to computed tomography (CT) scans to evaluate the primary femoral and tibial tunnels before revision anterior cruciate ligament (ACL) reconstruction leads to better agreement with the surgical approach than CT alone.

Methods: Fifteen patients who underwent revision ACL reconstruction were retrospectively identified. The mean age was 24.

Post-treatment Follow-up, Imaging, and Outcome Scores: Proceedings of the International Consensus Meeting on Cartilage Repair of the Ankle.

Background: The evidence supporting best practice guidelines in the field of cartilage repair of the ankle are based on both low quality and low levels of evidence. Therefore, an international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to report the consensus statements on Post-treatment Follow-up, Imaging and Outcome Scores developed at the 2017 International Consensus Meeting on Cartilage Repair of the Ankle.

The Postoperative Meniscus: Anatomical, Operative, and Imaging Considerations.

Meniscal surgery is commonplace. Patients who have had prior surgery may return for additional imaging for continued or new pain, limited range of motion, or interval injury. Accurate interpretation of postoperative imaging requires a clear understanding of the normal meniscal anatomy and biomechanics.

A Comparison of Plain Radiographs and Computed Tomography for Determining Canal Diameter of the Distal Phalanx.

Purpose: To compare plain radiographs and computed tomography (CT) when determining the narrowest diameter of the medullary canal of the distal phalanx.

Methods: A database review identified 48 patients (23 male, 25 female) who underwent a CT scan of the hand and plain radiographs of the same hand. Using digital imaging software, the smallest diameter of the medullary canal was measured for each finger (index, middle, ring, little) on CT and on radiographs.
