Comparative efficacy and safety of bicompartmental versus total knee arthroplasty: a systematic review and update meta-analysis.
Synthesis in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThis study was aimed at comparing the efficacy and safety of bicompartmental knee arthroplasty (BKA) and total knee arthroplasty (TKA) in treating bicompartmental knee osteoarthritis through a systematic evaluation and meta-analysis.
methodsA comprehensive systematic literature search of the Pub Med, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov databases was performed to identify the relevant scientific literature published until 1st March 2024. The eligible studies were evaluated for quality assessment and data extraction, and meta-analysis was performed using Review Manager 4.1 software.
resultsA total of 1378 studies were identified. Based on strict inclusion criteria, 12 studies were finally included in this meta-analysis. The results of the analysis revealed that BKA yielded better postoperative outcomes than TKA, in terms of Knee Society Score (KSS) Knee Score, Function Score, and range of knee flexion (P = 0.02; P < 0.0001; P = 0.0005, respectively). Intraoperative bleeding in the BKA group was significantly lower than that in the TKA group (P = 0.02), although postoperative complications (P < 0.05) were higher and operative time (P = 0.04) was longer in the BKA group. However, the two groups did not show any significant difference in terms of Oxford knee score and WOMAC pain score (P = 0.53 and P = 0.96, respectively). DISCUSSION: Our present results indicate that while BKA affords better improvement in knee function and quality of life in bicompartmental knee osteoarthritis than TKA, it also increases complications and operative time. Therefore, further studies are warranted to confirm these results and assess long-term outcomes and cost-effectiveness. OTHER: Systematic review registration PROSPERO CRD420-24551418.
