1 · What the graph read from it

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.

2 · The registry

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

purposeTo determine the clinical outcomes differences and complications in two comparable groups of patients undergoing computer aided surgery (CAS) and robotic-assisted (RA) posterior stabilised (PS) total knee arthroplasty (TKA) following functional alignment (FA) principles with tibial pre-cut at a minimum of 4-year follow-up.

methodsThis retrospective, monocentric and observational study included 94 consecutive patients undergoing PS TKA performed with CAS and RA-TKA following FA principles, between January 2017 and January 2020. Patients were followed with radiological and clinical assessment and evaluated with the Forgotten Joint Score-12 (FJS-12), Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR) and the 5-Level Likert Scale (5-LLS).

resultsOut of 94 patients two were lost to follow-up and one deceased in the robotic branch, eight patients were lost to follow-up and two were deceased in the navigated branch. Hereby, a total of 84 patients (87 knees) with a mean age of 69.2 ± 8.4 years were considered. A total of 40 cases were included in the CAS group; 44 cases were included in the RA-TKA group. No revisions were performed in any of the two groups, resulting in an overall Kaplan-Meyer survivorship rate of 100% for both cohorts. At last follow-up, no statistically significant differences were recorded between CAS and RA-TKA relative to FJS-12, KOOS-JR and 5-LLS (FJS-12: 89.4 ± 9.5 vs. 88.3 ± 13.4; KOOS-JR: 88.0 ± 10.2 vs 86.2 ± 11.5; 5-LLS 4.4 ± 1.7 vs 4.6 ± 2.1) respectively.

conclusionsNo significant outcomes differences and complications were detected between patients undergoing PS-TKA performed with either CAS and RA at a minimum 4-year follow-up. TKA performed with a patient-specific FA technique and with a soft tissue-preserving approach, showed excellent results with both CAS and RA-TKA. LEVEL OF EVIDENCE: Level III.
