Hospital-based Patient-specific Templates for Total Knee Arthroplasty: A Proof of Concept Clinical Study.
Article in Techniques in orthopaedics (Rockville, Md.), 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAll available patient-specific instruments or patient-specific templates (PSTs) are controlled by implant companies. Most of these companies outsource some of the steps of the PST such as imaging, preoperative planning, manufacturing of PST, and packing/sterilization. This is a proof of concept clinical study on the hospital-based PST system for total knee arthroplasty (TKA).
methodsA total number of 257 TKA procedures were performed on the basis of a new concept of hospital-based PSTs. All 5 steps of the PST [ie, imaging (computed tomographic scanning), planning, PST production, packing/sterilization, and surgery] were performed by the hospital. All cases included in this work are documented in the Egyptian Community Arthroplasty Register.
resultsAll cases had their surgeries performed without resorting to conventional intramedullary guides. Computed tomography-based imaging was easy and affordable. Planning was controlled by the surgeon. Polyamide nylon was the best available material and it was autoclavable. Desktop 3-dimensional printers were able to produce PSTs made of nylon, but it was difficult and time consuming. Industrial printers were superior in quality to desktop printers but more expensive. The whole process could be performed in as short a duration as 3 working days.
conclusionsHospital-based PST was feasible and it was facilitated by the introduction of desktop 3-dimensional printers. This technique was less expensive and more time saving than commercially available PSTs as well as the conventional TKA.
