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

purposeThere is only one prospective randomized trial on acute primary patellar dislocation in adolescents comparing the long-term outcome after conservative versus operative procedures. Therefore, the long-term outcome, patellar redislocation rate, and functional outcome after conservative versus operative procedures were investigated in a prospective randomized study.

methodsInitially, 36 patients with acute primary patellar dislocation were prospectively randomized to conservative (n = 20) versus operative procedures (n = 16) and 30 of them (83%), 15/20 with conservative and 15/16 with operative procedures, were reached for a follow-up interview 6 years after primary procedure.

resultsBaseline and clinical parameters were similar in the two groups. The prevalence of patellar redislocation rate at 3 and 6 years after primary procedure was higher in the conservative group (7/20, 35%, 3 years and 11/15, 73%, 6 years) versus in the operative group (0/16, 0%, 3 years and 5/15, 33%, 6 years) (p = 0.02). The knee function was slightly better 6 years after primary treatment in the operative group than in the conservative group. Most patients in both groups had excellent or good knee function at 6-year follow-up, but four patients (4/15, 27%) in conservative group and two patients (2/15, 13%) in operative group had poor knee function at 6-year follow-up. Four patients in conservative group (4/15, 27%) and two patients in the operative group (2/15, 13%) were unsatisfied with the procedure at 6-year follow-up.

conclusionsIn conclusion, the results suggest that both conservative and operative procedures are feasible options for treatment of acute primary patellar dislocation in adolescents. A new finding with clinical relevance in the present work is a significantly higher redislocation rate in conservative group compared to operative group after 6-year follow-up in acute primary patellar dislocation in adolescents.
