Posterior-stabilized vs cruciate-retaining TKA in osteoarthritic patients with genu recurvatum: a 2-year comparative analysis.

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
introductionPre-operative genu recurvatum (GR) in patients with knee osteoarthritis (OA) presents a surgical challenge during total knee arthroplasty (TKA). It remains unclear whether cruciate-retaining (CR) or posterior-stabilized (PS) TKA offers superior functional recovery and postoperative stability in this population.
methodsIn this single-centre retrospective cohort study, we analysed 102 patients with knee OA and physiological GR > 5° who underwent either CR-TKA (n = 60) or PS-TKA (n = 42). Clinical outcomes were assessed preoperatively, at 6 months, and at 2 years postoperatively using range of motion (ROM), and validated functional scores, International Knee Society Score (IKSS), Oxford Knee Score (OKS), Short Form-36 (SF-36). Recurrence of GR, complication rates, and revision procedures were also recorded. Statistical comparisons were performed using independent t-tests and chi-square tests.
resultsBoth groups demonstrated significant improvements across all functional outcomes. At the 6-month and 2-year follow-ups, the PS-TKA group demonstrated significantly better end range flexion and ROM than the CR-TKA group. At 2 years, recurrence of GR was 9.5% in the PS-TKA group versus 18.3% in the CR-TKA group (p < 0.05). There were no significant differences in IKSS, OKS, SF-36, patient satisfaction or expectation fulfilment. There were no significant differences in complications or revision rates between the groups.
conclusionBoth CR-TKA and PS-TKA provided substantial functional improvement in patients with pre-operative GR. PS-TKA demonstrated superior flexion and lower recurrence rates of GR but no difference in functional outcomes or revision rates. Given its enhanced extension stability, PS-TKA may be preferable in cases with significant posterior laxity. Implant selection should remain individualized based on intraoperative findings and patient-specific anatomical considerations.
