Effect of total knee arthroplasty on the spinopelvic parameters: A systemic review and metanalysis.
Article in World journal of orthopedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundSagittal spinopelvic alignment (SSA) is essential for preserving a stable and effective upright posture and locomotion. Although alterations in the SSA are recognised to induce compensatory modifications in the pelvis, hips, and knees, the inverse relationship concerning knee pathology undergoing total knee arthroplasty (TKA) has been examined by a limited number of studies, yielding inconclusive results.
aimTo generate evidence of the effect of TKA on the SSA from existing literature.
methodsDatabases like PubMed, EMBASE, and Scopus were used to identify articles related to the "knee spine syndrome" phenomenon using a combination of subject terms and keywords such as "spinopelvic parameters", "sagittal spinal balance", and "total knee arthroplasty" were used with appropriate Boolean operators. Studies measuring the SSA following TKA were included, and research was conducted as per preferred reporting items for systematic review and meta-analysis guidelines.
resultsA total of 475 participants had undergone TKA, and six studies measuring SSA were analysed. Following TKA, pelvic tilt was the only parameter that showed significant changes, while lumbar lordosis (LL), pelvic incidence, and sacral slope were non-significant, as evident from the forest plots.
conclusionThe body's sagittal alignment is a complex balance between pelvic, spine, and lower extremity parameters. TKA, while having the potential to correct the flexion contracture, can also correct it. Still, the primary SSA for spinal pathology,
