Trajectories of Work Ability After Total Hip and Knee Arthroplasty: A Latent Class Growth Analysis.
Article in Journal of occupational rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTotal hip arthroplasty (THA) and total knee arthroplasty (TKA) as treatments for osteoarthritis increasingly affect working-age adults. However, little is known about the development of work ability after THA and TKA. This study investigated different trajectory classes of work ability after THA and TKA.
methodsThis prospective study included 146 working patients (THA n = 51, TKA n = 95). They received THA/ TKA treatment as usual, including surgery, rehabilitation, and optional post-rehabilitation programmes. The primary outcome work ability was assessed five times (before surgery, end of rehabilitation, 3-month, 6-month, and 12-month follow-up) with the Work Ability Score. Additionally, the questionnaires included sociodemographic, health-, rehabilitation-, and work-related data. We applied a latent class growth analysis to identify distinct trajectory classes of work ability over 12 months, and examined associated factors using univariable multinominal logistic regression analyses in MPlus.
resultsWe found three distinct trajectory classes of work ability within one year after THA/ TKA: no improvement (24.5%), delayed improvement (36.6%), and early improvement in work ability (38.9%). Preoperative predictors for work ability trajectory classes were sex, pain intensity, functional ability in everyday life, and risk of work-related disabilities. Furthermore, work ability trajectory classes were associated with participation in the T-RENA post-rehabilitation programme, and with pain intensity one year after having started rehabilitation.
conclusionDespite the fact that most patients showed improvements in work ability after THA and TKA, there is a noteworthy proportion who did not. Further studies are needed to enhance identification of these individuals, and to offer targeted interventions.
trial registrationThe study is registered in the German Clinical Trials Register (DRKS00029630).
