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

introductionThe management of isolated unicompartmental osteoarthritis in the patient aged 70 years and older is an issue of debate. The purpose of the present study was to retrospectively evaluate the outcomes of patients aged over 70 years who underwent unicompartmental knee replacement (UKR) for the treatment of isolated unicompartmental osteoarthritis. The hypothesis was that this represents a safe and viable procedure leading to improved functional outcome in elderly patients affected by isolated unicompartmental osteoarthritis.

methods22 consecutive medial compartment UKRs performed between 1998 and 2008 were retrospectively evaluated. Mean age was 74 years (range 70-93 years). Patients were evaluated preoperatively and after an average follow-up of 6.2 years (range 2 to 8). Assessment included KOOS score, WOMAC score, Knee Society Score. Standard X-rays were performed prior to surgery and at follow-up.

resultsTwenty patients showed a statistically significant improvement in all parameters. One patient who was 93 years old at the time of surgery died for unrelated causes. One patient required conversion to a total knee arthroplasty. DISCUSSION: UKR is a safe and clinically effective procedure, which has been proven valuable for the treatment of elderly patients with isolated unicompartmental osteoarthritis and with initial degenerative signs in the other compartments.

conclusionAge more than 70 does not appear to be a contraindication to the procedure. LEVEL OF EVIDENCE: IV (case series).
