Neglected patella nonunion repair with tension band plating, quadricepsplasty, and tibial autograft.
Article in OTA international : the open access journal of orthopaedic trauma, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Nonunion of a displaced patellar fracture results in an elongated, incompetent extensor mechanism. Surgical repair must address loss of mobility of the extensor mechanism tendon and muscular components, bone resorption, impaired fracture biology, a wide fracture gap, and distracting forces across the nonunion site. A novel patellar nonunion fixation technique for the treatment of chronic patella nonunion is described including medial parapatellar arthrotomy, anterior interval release, open lysis of intra-articular adhesions, lateral capsular release, modified quadricepsplasty, tension band plating, autograft bone harvested from the proximal tibia, and quadriceps tendon advancement. Five patients treated with this technique achieved both clinical and radiographic union within 3 months and a mean active knee flexion of 98 degrees (range 45-140 degrees) with independent ambulation and without complication at 1-year follow-up.
