1 · What the graph read from 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.

2 · The registry

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

backgroundPatients with unicompartmental radiographic arthritis but bicompartmental symptoms pose a clinical challenge. Some surgeons may perceive it as a contraindication for unicondylar knee arthroplasty (UKA). We investigated patient outcomes 2 years after simultaneous ipsilateral arthroscopy and UKA as compared to a similar group of patients who had total knee replacement (TKA) for a similar clinical presentation.

methodsWe identified 9 patients with simultaneous ipsilateral arthroscopy and UKA between 2004 and 2013, and 12 clinically similar patients treated with TKA.

resultsAt 1- and 2-years, SF-12 physical scores were significantly improved in the UKA-scope group than in the TKA group (47.2 vs 40.3, p = 0.042; 48.3 vs 32.6, p = 0.026). WOMAC pain score, WOMAC stiffness score, WOMAC function and KSFS were significantly improved in the UKA-scope group at 2 years as compared to the TKA group (98.7 vs 63.8, p = 0.030), (90.1 vs 43.8, p = 0.013), (92.3 vs 55.2, p = 0.027 and (92.3 vs 55.2, p = 0.027), respectively). Change in score from baseline for KSFS, SF-12 physical and WOMAC stiffness were significantly improved in the UKA-scope group at 2 years compared to TKA, (28.3 vs -5, p = 0.041), (13.6 vs 3.0, p = 0.026), (52.6 vs -6.3, p = 0.025), respectively.

conclusionThis study shows that patients with isolated compartment radiographic disease but with bicompartmental symptoms can benefit from UKA and simultaneous arthroscopy. Further, TKA for isolated compartment radiographic disease in this limited series had poorer outcomes. We obtain MRI selectively when physical exam and radiographic findings suggest isolated arthritic disease in patients with bicompartmental symptoms.
