Comparison of Survival Rate between Posterior-Stabilized and Constrained Condylar Articulations in Revision Total Knee Arthroplasty: A Minimum 5-Year Follow-up Analysis.

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
Background: Revision total knee arthroplasty (RTKA) is a technically demanding procedure for failed primary TKA. Posterior-stabilized (PS) and constrained condylar knee (CCK) articulations are commonly used for RTKA, but comparison of these articulations in RTKA is scarce. The aim of this study was to compare survival rates and clinical outcomes of RTKAs using PS articulation and CCK articulation. Methods: This study conducted a retrospective analysis of 86 RTKAs (PS, n = 41; CCK, n = 45) with a mean follow-up of 9.15 ± 2.79 years. Clinical outcomes were evaluated using the Hospital for Special Surgery score, Knee Society Score, and The Western Ontario and McMaster Universities Osteoarthritis Index at final follow-up. The survival rate of each group was analyzed by Kaplan-Meier survival analysis and Cox-hazard progression model. Results: Clinical outcomes were improved in both groups without significant difference. Twelve patients had orthopedic complications (4 in PS group and 8 in CCK group). Eight of them underwent re-RTKA (3 in PS group and 5 in CCK group). The articulation design did not influence the failure. The estimated 10-year survival rate was 92.7% in the PS group and 88.2% in the CCK group with no significant difference ( Conclusions: In RTKA, both PS and CCK showed similar survival rates and clinical outcomes at a mean follow-up of 9.2 years. Implant articulation did not affect the outcomes when properly indicated.
