Technical Properties and Biological Safety of Reprocessing Technique for a Handpiece of Disposable Pulsatile Lavage Device: An Experimental Study.

Introduction: Bony surface cleaning using a pulse lavage device (PLD) is essential for modern cementation of hip and knee arthroplasties. This costly single-use device is a medical waste and unaffordable for some patients. Reprocessing is a worldwide standard strategy to solve this problem.

Anterior cortical line of femur and tibia is more accurate than mid-shaft line to determine knee extension angle relative to sagittal mechanical axis during total knee arthroplasty.

Background: Accurate assessment of knee extension angle relative to sagittal mechanical axis (SMA) during TKA is usually obtained by computer navigation. Whether the lines along anterior cortex of distal femur and proximal tibia in short-knee imaging are accurate in determining knee extension angle has not been investigated.

Methods: A prospective study was conducted on 106 patients (116 knees) who underwent primary TKA.

Digital Templating of THA Using PACS and an iPhone or iPad is as Accurate as Commercial Digital Templating Software.

Background: Digital templating is a standard preoperative planning method in THA. Unfortunately, many hospitals cannot afford the software or have accessibility barriers owing to a limited number of installed computer workstations. We created a templating method using a picture archiving and communication system and the Keynote program on a mobile phone.

Accuracy of a New Digital Templating Method for Total Hip Arthroplasty Using Picture Archiving and Communication System (PACS) and iPhone Technology: Comparison With Acetate Templating on Digital Radiography.

Background: Preoperative templating for total hip arthroplasty (THA) on digital radiography can be achieved using templating software or hybrid methods (acetate templates overlaid on digital images). No studies have examined templating with a mobile phone. We evaluated the accuracy and reproducibility of a new digital templating method using the picture archiving and communication system (PACS) and iPhone, compared with the hybrid method for cementless THA.

Accuracy of intraoperative estimation of femoral stem anteversion in cementless total hip arthroplasty by using a digital protractor and a spirit level.

Background: The femoral component anteversion during surgery is traditionally assessed by a visual assessment of the surgeon and has proven to be imprecise. We sought to determine the accuracy of a digital protractor and a spirit level to measure the stem anteversion during cementless THA.

Methods: A prospective study was conducted among 107 patients (114 hips) who underwent primary cementless THA via posterolateral approach.
