Bilateral knee pigmented villonodular synovitis in a young adult: Radiologic diagnosis and surgical approach.

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
Pigmented villonodular synovitis is a rare proliferative disorder of the synovial joints, characterized by synovial thickening and hemosiderin deposition. It predominantly affects the knee joint, with bilateral involvement being exceedingly rare. We present a case of diffuse bilateral pigmented villonodular synovitis in a 20-year-old female, initially presenting with left knee pain and swelling, diagnosed via MRI. Following an open total synovectomy, the patient developed postoperative stiffness, requiring arthroscopic arthrolysis. Subsequently, similar symptoms emerged in the right knee, leading to a second synovectomy and subsequent arthrolysis. Despite the challenges associated with managing this condition, including a high recurrence rate and postoperative stiffness, the patient showed significant improvement 1 year postoperatively. This case underscores the importance of thorough synovectomy and highlights the potential need for further surgical intervention to address complications such as stiffness.
