Total versus unicompartmental knee replacement for isolated lateral osteoarthritis: a matched-pairs study.
Article in International orthopaedics, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 papers, 4 of them syntheses that pooled it.
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
purposeThe aim of this study was to compare the functional outcome of patients following unicompartmental knee replacement (UKR) using the Oxford domed lateral UKR to patients who underwent cruciate-retaining total knee replacement (TKR) for isolated osteoarthritis in the lateral compartment.
methodsWith the help of our institutional database, we retrospectively identified 22 matched pairs with regards to age, gender and body mass index (BMI). Functional outcome was measured using the Oxford Knee Score (OKS) and range of motion (ROM). Complications and revisions were recorded.
resultsThe mean follow-up was 22 (UKR) and 19 (TKR) months, respectively. Patients following UKR had a statistically significant higher mean postoperative OKS and ROM: mean OKS was 43 [standard deviation (SD) 4] for UKR and 37 (SD 9) for TKR, respectively (p = 0.023); ROM was 127° (SD 13) for UKR and 107° (SD 17) for TKR (p < 0.001). Additionally the change in score was statistically significant higher in patients following UKR in the OKS (14.3 (SD 6) vs. 9.6 (SD 8)) and in the range of motion (+12° (SD 19) vs. -3° (SD 20)), (p = 0.041 and p = 0.01 respectively). Survival at two years using revision for any reason as the endpoint was 96% [95% confidence interval (CI) 72-99] for UKR and 100% for TKR (Log-rank test, p = 0.317).
conclusionThe functional results of mobile-bearing UKR for isolated osteoarthritis in the lateral compartment compare favourably to those after cruciate-retaining TKR in the short term. To compare survival and complications after both procedures, longer-term follow-up is necessary.
