Suture Tape Augmentation of Screw Fixation Reduces Fragment Migration in Tibial Tubercle Osteotomy: A Biomechanical Study.

Background: Tibial tubercle osteotomy (TTO) is a complex surgical procedure with a significant risk of complications, which include nonunion and tibial fracture.

Purpose: To determine whether an additional suture tape augmentation can provide better biomechanical stability compared with standard screw fixation.

Study Design: Controlled laboratory study.

Visual classification of running economy by distance running coaches.

This study assessed the ability of coaches to rank-order distance runners on running economy (RE) through visual assessment. Running economy was measured in five trained recreational distance runners at a speed of 3.57 ms, with a minimum VO difference of 2-mL.

3D-Printed Patient-Specific ACL Femoral Tunnel Guide from MRI.

Background: Traditional ACL reconstruction with non-anatomic techniques can demonstrate unsatisfactory long-term outcomes with regards instability and the degenerative knee changes observed with these results. Anatomic ACL reconstruction attempts to closely reproduce the patient's individual anatomic characteristics with the aim of restoring knee kinematics, in order to improve patient short and long-term outcomes. We designed an arthroscopic, patient-specific, ACL femoral tunnel guide to aid anatomical placement of the ACL graft within the femoral tunnel.

Water-based lubricant as an adjunct to wound toilet: Validation of a technique by experiment.

Introduction: Metal debris can produce a foreign body inflammatory reaction or as third body wear in the situation of joint arthroplasty. We evaluate a simple method for reducing this debris using a sterile water-based lubricating gel.

Materials And Methods: Eight experimental surgical models consisting of porcine muscle overlying a polyethylene tube with a titanium locking plate and screws secured were constructed.

DIY 3D printing of custom orthopaedic implants: a proof of concept study.

3D printing is an emerging technology that is primarily used for aiding the design and prototyping of implants. As this technology has evolved it has now become possible to produce functional and definitive implants manufactured using a 3D printing process. This process, however, previously required a large financial investment in complex machinery and professionals skilled in 3D product design.

Rapid prototyping in orthopaedic surgery: a user's guide.

Rapid prototyping (RP) is applicable to orthopaedic problems involving three dimensions, particularly fractures, deformities, and reconstruction. In the past, RP has been hampered by cost and difficulties accessing the appropriate expertise. Here we outline the history of rapid prototyping and furthermore a process using open-source software to produce a high fidelity physical model from CT data.
