We aimed to determine the reliability, accuracy and the clinical role of digital templating in the pre-operative work-up for total knee replacement. Initially a sample of ten pre-operative digital radiographs were templated by four independent observers to determine the inter- and intra-observer reliability of the process. Digital templating was then performed on the radiographs of 40 consecutive patients undergoing total knee replacement by a consultant surgeon not involved with the operation… 
Digital templating of rotating hinge revision and primary total knee arthroplasty
TLDR
In the cases were the templating was incorrect, the prosthesis was implanted smaller than the preoperative plan and very good results can be made with this prosthesis.
Algorithm based automatic templating is less accurate than manual digital templating in total knee arthroplasty
TLDR
Surgeons are cautioned from exclusively using an automatic algorithm as it is less accurate than manual templating for TKA, and race and the presence of a standardized calibration marker on preoperative radiographs effect the accuracy of digital Templating.
Reliability and accuracy of digital templating for the humeral component of total shoulder arthroplasty
TLDR
Digital templating is not a useful guide for pre-operative surgical planning and should not be used to select a prosthesis.
Preoperative Acetate Templating In Total Knee Arthroplasty: Does It Matter?
TLDR
It is concluded that the manual templating is an indispensable preoperative technique for TKA operations and a higher tendency to template smaller size for both components in total knee arthroplasty is recommended.
Effect of training level on accuracy of digital templating in primary total hip and knee arthroplasty.
The use of digital radiography and templating software continues to become more prevalent in orthopedics as the number of total hip arthroplasty (THA) and total knee arthroplasty (TKA) procedures
Digital templating in primary total hip and knee arthroplasty.
TLDR
Digital templating is an effective means for predicting the size of THA and TKA components, thus remaining a viable option as the authors transition into the modern era of digital radiography.
Accuracy of Preoperative Templating in Total Hip Arthroplasty
TLDR
Anteroposterior pelvic radiographs of 20 men and 33 women who underwent uncemented THA of the right and left sides using a single prosthesis were reviewed to assess the accuracy of templating in total hip arthroplasty (THA).

Assessment of reproducibility and accuracy in templating hybrid total hip arthroplasty using digital radiographs.
TLDR
On-screen templating of digital radiographs with standard acetate templates is accurate and reproducible if a radiopaque marker such as a ten-pence coin is included when the original radiograph is taken.
Comparison of analog and digital preoperative planning in total hip and knee arthroplasties
TLDR
The digital preoperative plans which were performed by someone other than the surgeon were less accurate than the analog plans prepared by the surgeon, and planning of component sizes for total knee arthroplasties is an accurate procedure when performed digitally.
Accurate scaling of digital radiographs of the pelvis. A prospective trial of two methods.
TLDR
The coin method was significantly more accurate and reliable and radiographer friendly than the caliper method and is recommended as the method of choice for scaling radiographs of the pelvis before hip surgery.
Disc calibration for digital templating in hip replacement.
TLDR
A method whereby a planar disc placed on the radiographic cassette accounts for the expected magnification and is reliable, robust, cost effective and acceptable to patients and radiographers is devised.

TLDR
A comparison of the bone dimensions from the study data and the dimensions of the implants indicated that the smaller sizes were too small while the larger sizes tended to be too large, which will allow manufacturers to make more appropriate determinations of the sizes and aspect ratios of components for use in total knee arthroplasty.
A simple guide to determine the magnification of radiographs and to improve the accuracy of preoperative templating.
TLDR
A group of patients undergoing uncemented arthroplasty of the hip was at high risk for intraoperative fracture of the femur because the magnification of the radiograph was larger than that of the template.
Instability after total knee arthroplasty.
TLDR
The goal of this Instructional Course Lecture is to provide an overview of the causes and treatments of each type of instability after total knee arthroplasty: extension instability, flexion instability, and genu recurvatum.
Intraoperative measurements of male and female distal femurs during primary total knee arthroplasty.
TLDR
The data suggest that for any given AP femoral dimension, women tend to have a narrower ML dimension than men, independent of AP height, and an AP/ML ratio of 0.80 most closely approximates a standard-sized distal femur across gender.
Osteoporosis and Anterior Femoral Notching in Periprosthetic Supracondylar Femoral Fractures: A Biomechanical Analysis
TLDR
Femoral notching during total knee arthroplasty significantly decreases distal Femoral torsional load to failure and is best predicted by a combination of the measures of distal femoral bone-mineral density and polar moment of inertia.
