Pedicled Rectus Femoris Flap for Restoration of Suprapatellar Quadriceps Tendon and Defect Coverage after Multiple Reconstruction Attempts-A Case Report and Literature Review.

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 is no unified approach for restoring the suprapatellar quadriceps tendon and covering tissue defects simultaneously. In this case report, we present the pedicled myocutaneous rectus femoris flap as one effective approach in two cases with extensive loss or impairment of the suprapatellar muscle-tendon structures after trauma-related suprapatellar quadriceps tendon rupture and multiple reconstruction attempts. Additionally, we provide a literature review of the reconstructive use of the functional pedicled myocutaneous rectus femoris flap.
methodsTwo male patients, 48 and 74 years old, with extensive loss or impairment of the suprapatellar muscle-tendon structures due to multiple reconstruction attempts, underwent restoration of the knee extension with a pedicled myocutaneous rectus femoris flap.
resultsThree months after reconstruction, both patients were able to walk freely, unaided. After a six-month follow-up, the free passive mobility of the knee joint was restored, and the active extension of the knee joint was possible in both patients.
conclusionThe authors conclude that the pedicled rectus femoris flap is a reliable method for the restoration of knee extension, with excellent functional results in cases of suprapatellar tendon lesions. Further to the functional restoration, this technique has the additional advantage of simultaneously achieving coverage of soft-tissue defects, while a direct closure of the donor site is possible. Elderly patients and patients with relevant comorbidities or multiple revisions may especially benefit from this technique.
