Effect of an enhanced recovery after surgery program on total hip and knee arthroplasty in a university hospital: a two-cohort study.
Article in International orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundEnhanced Recovery After Surgery (ERAS®) is a coordinated, evidence-based program delivered through a multidisciplinary team, which objective is to improve outcomes and patient satisfaction, while minimizing complications. The objective of this two-cohort study is to evaluate the clinical impact of an ERAS program on elective primary hip (THA) and knee (TKA) arthroplasties with regards to hospital length of stay, during the first 12 months after implementation.
methodsWe compared a retrospective pre-ERAS with a prospective ERAS cohort. Key aspects of this program included preoperative education, minimal fasting, standardised, anaesthetic and surgical techniques, multimodal analgesia, and early mobilization. The primary outcome was hospital length of stay. Other outcomes included rest, dynamic pain scores, and rates of complications.
resultsFrom December 1st, 2021 to November 30th, 2022, data from 267 patients (138 THA, 129 TKA) were compared with data from 258 patients (128 THA, 130 TKA) collected between December 1st, 2022, and November 30th, 2023, who underwent the ERAS® program (total: 525 patients). The mean hospital length of stay for THA patients before ERAS® was 5.5 ± 2.9 days versus 4.5 ± 2.0 days after ERAS® implementation (p = 0.002). For TKA patients, it was 6.6 ± 3.1 days before vs 5.6 ± 1.9 days after ERAS® implementation (p = 0.001). Rest, dynamic pain scores, and rates of complications were similar between groups except for pneumonia in patients undergoing TKA.
conclusionThe implementation of an ERAS® program for hip and knee arthroplasty led to a reduced hospital length of stay, below the Swiss national average, without impacting pain outcomes and rates of complications.
