Quadricepsplasty for Patellar Obligate (Habitual) Lateral Flexion Dislocation.

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
There are multiple underlying etiologies of patellar instability including both osseous and soft-tissue factors. Obligate flexion dislocation consists of lateral dislocation of the patella, occurring each time the knee flexes. This generally results from a predominantly lateral contracture of the extensor mechanism and can be technically challenging to manage. Quadricepsplasty can be of particular clinical utility for obligate flexion dislocation and constitutes a realignment of the proximal soft-tissue attachments of the patella. The described technique features isolation of the 4 muscles of the quadriceps and subsequent stepwise lengthening of the vastus lateralis, advancement of the vastus medialis obliquus, and Z-lengthening of the rectus femoris and vastus intermedius. This technique can be used in isolation or in combination with other procedures, such as medial patellofemoral ligament reconstruction, to surgically address patellofemoral maltracking.
