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

introductionTotal knee arthroplasty (TKA) in the elderly population is becoming increasingly prevalent. This study aimed to compare outcomes of patients aged ≥80 years with those aged < 80 years at time of TKA and to assess the effect of fast track peri-operative care on outcomes in the elderly. MATERIALS AND

methods422 TKAs were performed in aged ≥80 at the time of surgery between 2009 and 2018. A control group aged < 80 years (37-79 +/- 7.6) was established. Peri-operative mortality, complications, 30-day re-admission, length of stay (LOS) and rehabilitation parameters were recorded.

resultsMean age at operation for the ≥80's group and control group was 82.7 (80-93+/- 2.5) and 69.3 (37-79+/- 7.6) years respectively. Post-operative Knee Society Functional Assessment (KSFA) scores were higher in the control group (49 vs. 57, p = 0.003). Average LOS was longer in the ≥80's group (17.2 vs. 12.4 days respectively, p < 0.01). Mortality within 3 months of operation was 0.7% in the ≥80 group and 0% in the control group. Incidence of complications was comparable between the two groups at 12.8 and 12.9% for the group ≥80's and control groups respectively (p = 0.962). Patients ≥80 years, receiving fast track peri-operative care had significantly shorter LOS and higher post-operative KSFA scores at all time points post-operation and shorter LOS (p < 0.01) compared to those who received conventional rehabilitation. LOS was longer in the ≥80's group, which was likely related to higher levels of comorbidities. Complications were comparable in the two groups but were more severe in the elderly. Mortality rate after TKA was very low even in those over the age of 80. Younger patients benefited more in terms of functional improvement after TKA.

conclusionTKA is a safe and efficacious procedure for the elderly. More severe complications, longer length of stay and smaller gains in functional improvement can be expected in the elderly compared to younger patients. Fast track peri-operative care is useful in improving outcomes after TKA for elderly patients.
