Assessing the accuracy of patient-specific guides for total knee arthroplasty.

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
purposePatient-specific guides have been introduced recently as a means of making accurate bone cuts through custom cutting blocks constructed based on pre-operative three-dimensional imaging. However, the controversy concerning the improved results of patient-specific guides have not been resolved yet; in addition, there have been no studies to investigate the causes of variable with inconsistent results and solutions for the causes.
methodsThirty eight patients (38 knees) underwent total knee arthroplasty with patient-specific guides. The mean age of the patients was 68 years (SD ± 6.3), and all patients had a minimum 2-year follow-up. An intra-operative alignment using navigation and the causes of outliers were evaluated.
resultsAn average coronal alignment of PSI jigs was 0.5° (SD ± 0.9°) in femur and 0.1° (SD ± 0.8°) in tibia, and the number of outliers was two and three cases, respectively. An average sagittal alignment was 0.6° (SD ± 0.9°) in femur and 5.5° (SD ± 1.1°) in tibia, and the number of outliers was three and five cases, respectively. All outliers resulted from large osteophytes near the contact point of patient-specific guides which disturb sitting of the guide.
conclusionIt was suggested that patient-specific guides were an effective and safe method to achieve accurate alignments, with no additional intra-operative complication. It is important to note that surgeons need to be precautious using the patient-specific instrumentation in patients with severe varus deformity. In addition, existing osteophytes which disturb sitting of the guides should be carefully evaluated pre-operatively and intra-operatively. LEVEL OF EVIDENCE: IV.
