Results of total knee arthroplasty with NexGen LPS-Flex for osteoarthritis in the valgus knee: a study of 26 patients followed for a minimum of 2 years.

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
The present study aimed to examine the results of total knee arthroplasty (TKA) with the NexGen Legacy posterior-stabilized (LPS)-Flex system for osteoarthritis in the valgus knee. Between 2003 and 2011, 27 valgus knees in 26 patients who underwent TKA with the NexGen LPS-Flex implant were clinically and radiologically evaluated after a minimum follow-up of 2 years. The original diagnosis was osteoarthritis. Knee Society Knee Score (KSKS), Knee Society Function Score (KSFS), maximum flexion angle, maximum extension angle, and radiological femorotibial angle (FTA) were evaluated pre- and postoperatively. The mean KSKS improved from 42.6 before surgery to 82.2 by the final follow-up (p < 0.01), and the mean KSFS improved from 41.1 to 80.9 (p < 0.01). The mean maximum flexion angle changed from 109.1° to 117.3° (no statistical significance) and the maximum extension angle improved from -9.7° to -3.6° (p < 0.05) postoperatively. The postoperative radiological FTA was 172.4°, which was closer to a neutral angle (174°) than the preoperative FTA (166.4°) (p < 0.01). None of the patients had undergone revision surgery by the final follow-up. As a conclusion, TKA with the NexGen LPS-Flex implant for osteoarthritis in the valgus knee resulted in satisfactory improvement regarding objective outcomes, although a longer term follow-up with a greater number of cases is necessary to verify these results.
