Progression of patellofemoral joint cartilage degeneration within 1 year after medial meniscus posterior root repair: A retrospective study.

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
Purpose: To assess postoperative progression of patellofemoral (PF) cartilage degeneration after medial meniscus posterior root (MMPR) repair and identify potential risk factors. Methods: Data from patients who underwent transtibial pullout repair for complete radial MMPR tears between April 2018 and October 2021 were retrospectively investigated. Patients with severe chondral lesions of the PF joint at primary surgery were excluded. All patients underwent second-look arthroscopy at 12 months postoperatively. Postoperative changes using the International Cartilage Repair Society (ICRS) grade were evaluated. Associated open magnetic resonance imaging (MRI) findings were assessed. Results: In total, 40 patients (30 women, 10 men; mean age: 64.0 years) were evaluated. PF joint cartilage degeneration progressed significantly postoperatively. Abnormal signal intensity (ASI) of the infrapatellar fat pad (IPFP) was observed in 15 (37.5%) patients. Arthroscopic findings in groups between IPFP with and without ASI were compared. The incidence of postoperative ICRS grade worsening (≥2 grades) on the patella or trochlea was significantly higher among patients with ASI (53%) than among those without (20%, Conclusions: Progressive PF cartilage degeneration occurred following MMPR repair, highlighting the need for diligent postoperative PF joint management. Level of Evidence: Level IV case series.
