Knee Realignment, Life Realigned: A Systematic Review on KOOS-QOL Improvement after Osteotomy.
Article in Medeniyet medical journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Degenerative knee osteoarthritis (OA) impairs joint function and quality of life. Osteotomies such as distal femoral osteotomy (DFO), double level osteotomy (DLO), and medial open wedge high tibial osteotomy (MOWHTO) aim to restore alignment and function. Methods: A systematic review and meta-analysis were conducted following PRISMA guidelines. Studies from 2019-2024 were identified from PubMed, Scopus, ScienceDirect, and China National Knowledge Infrastructure. Included studies reported Knee injury and Osteoarthritis Outcome score (KOOS) quality of life scores (QOL) before and after surgery in patients with varus deformity and compartmental OA. Eight studies with 501 patients were analyzed. Results: All techniques improved KOOS scores. The greatest improvement was seen in DFO (standardized mean difference=-3.13), followed by DLO (-2.44) and MOWHTO (-2.38). Heterogeneity ranged from 0% to 24%. DFO showed the highest improvement with lower complication risk. Conclusions: DFO provides the greatest QOL improvement. DLO is useful for complex deformities, while MOWHTO suits active patients. Standardized techniques and advanced technologies are needed for optimal outcomes.
