Open and arthroscopic deepening trochleoplasty improves post-operative outcomes: A systematic review of the literature reveals lack of comparability between techniques.
Synthesis in Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
purposeDeepening trochleoplasty improves outcomes in patients with trochlear dysplasia. The aim of this systematic review was to present the outcomes after open thin-flap, open thick-flap and arthroscopic deepening trochleoplasty.
methodsA systematic review was conducted using the PRISMA guidelines. Literature was searched in the PubMed, EMBASE and Cochrane databases on 16 December 2024. All studies from the inception of the databases to the date of the search were included in the search. Studies were included if they examined patients with patellar instability and trochlear dysplasia treated with either open or arthroscopic deepening trochleoplasty and reported pre- and post-operative outcomes. Two independent reviewers screened titles and abstracts, reviewed the full text and performed the quality assessment.
resultsA total of 32 studies, consisting of 1435 trochleoplasty cases in 1310 patients, were included. Of the included studies, 21 concerned open thin-flap trochleoplasty, 8 concerned open thick-flap trochleoplasty and 3 concerned arthroscopic trochleoplasty. The most used patient-reported outcome measures were the Kujala score, International Knee Documentation Committee score, visual analogue scale pain score, Lysholm Knee Score and Tegner Activity Scale; and the most reported radiological outcome measures were trochlear sulcus angle, trochlear bump, trochlear depth, tibial tubercle-trochlear groove distance, Caton-Deschamps index and patellar tilt. All three trochleoplasty techniques lead to improvements in post-operative outcome measures.
conclusionDeepening trochleoplasty improves post-operative outcome using both open thin-flap, open thick-flap and arthroscopic deepening technique. Comparison between the techniques is challenging due to low methodological quality of studies. Further research is needed to document treatment effect and improve patient outcome. LEVEL OF EVIDENCE: Level IV.
