Comparison of Patellar Tracking Following Kinematic Alignment Versus Mechanical Alignment Total Knee Arthroplasty via the Mini-Subvastus Approach.
Trial report in Orthopaedic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectivesDifferent alignment strategies (kinematic alignment [KA] versus mechanical alignment [MA]) during total knee arthroplasty (TKA) significantly influence postoperative patellar tracking. This study aimed to compare radiological parameters of patellar tracking and clinical outcomes between KA-TKA and MA-TKA via the mini-subvastus approach.
methodsThis prospective randomized controlled study included 234 patients who underwent KA-TKA and MA-TKA from January 2022 to October 2023. The preoperative and postoperative patellar tilt, lateral patellar shift, knee society score (KSS), oxford knee score (OKS), and intraoperative patellar lateral retinacular release (LRR) rate were measured. In addition, radiological parameters and clinical outcomes were compared between the LRR and non-LRR groups. Independent samples t test and chi-square test were used to compare the differences between groups.
resultsTwo-hundred and thirty-four patients were followed up for 12 months post-TKA. No significant differences were observed between the two groups in terms of the demographics and pre- or post-operative radiological parameters of patellar tracking (p > 0.05). The postoperative KSS and OKS were significantly higher in the KA group than in the MA group (p < 0.05). The LRR rate was 6.7% (8/120) in the KA group and 25.4% (29/114) in the MA group, and the difference was statistically significant (x
conclusionsKA-TKA via the mini-subvastus approach can achieve both good patellar tracking and clinical outcomes. Avoiding muscle damage and refraining from excessive soft tissue release are crucial to improving postoperative patient comfort. In our opinion, KA-TKA via the mini-subvastus approach may be a more suitable surgical option.
