Restoration of Knee Function After Tibial Tubercle Proximalization for Infrapatellar Contracture Syndrome Following Patellar Fracture Surgery.

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
Infrapatellar contracture syndrome (IPCS) is a rare but functionally disabling condition characterized by anterior knee fibrosis and patellotibial impingement. We report the case of a 59-year-old woman who developed IPCS after undergoing tension band wiring for a patellar fracture, presenting with pain, quadriceps weakness, and marked patella baja (Insall-Salvati ratio: 0.377). Proximalization of the tibial tubercle by 15 mm restored patellar height and improved knee flexion from 120° preoperatively to 150° at the one-year follow-up. At two years, the patient achieved full squatting and floor sitting (seiza), with no extension lag, quadriceps strength of 86.4 N (contralateral: 96.6 N), and an improved Timed Up and Go score from 12.89 to 6.86 seconds. Tibial tubercle proximalization may be an effective tendon-sparing option for IPCS with patella baja, enabling restoration of patellar height, improved range of motion, and early rehabilitation without direct tendon manipulation.
