Ninety-three point seven percent pooled 10-year survival rate following lateral unicompartmental knee arthroplasty for isolated lateral knee osteoarthritis-A systematic review and meta-analysis.
Review in Journal of experimental orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Purpose: To systematically review the available evidence on long-term outcomes following lateral unicompartmental knee arthroplasty in lateral knee osteoarthritis. Methods: An advanced search was done throughout three electronic databases (PubMed, Scopus and Embase) involving the words 'lateral unicompartmental knee arthroplasty' and 'lateral knee osteoarthritis'. Inclusion and exclusion criteria were set. The Newcastle-Ottawa scale was used in assessing the study quality. Extracted were study demographics, survival rate, follow-up period, indications and contraindications, implant type, revision rate and outcome tools. The data were systematically collected and meta-analysed. Results: After an initial screening of 1864 articles, 15 articles were selected for the review. The study quality was evaluated as 'high' in most of the selected articles. The pooled 10-year survival rate was 93.7% (95% CI: 92.5%-94.9%). The mean follow-up period ranged between 7 and 14 years (pooled mean follow-up 9.1 years). A significant negative correlation was found between patient BMI and survival rate ( Conclusions: Lateral unicompartmental knee arthroplasty for isolated lateral knee osteoarthritis provided a high long-term survival rate with a low 10-year revision rate. This was provided in a non-ACL-deficient knee with a preoperative flexion of above 90 degrees and a correctable valgus by using a fixed-bearing implant. Females were more likely to undergo this procedure. A negative correlation was found between patient BMI and survival rate. There was a notable variability in the reported outcome measures among studies. Level of Evidence: Level IV, systematic review of therapeutic studies.
