Every orthopaedic surgeon who has ever sat through a promotion committee, grant panel, or institutional ranking exercise has felt the same quiet unease. The numbers never quite add up. Papers that took years of careful clinical work, multi-centre collaboration, or technical innovation land with a fraction of the citations that a single high-profile trial in cardiology or oncology can attract in the same timeframe. For years, the community has known this was true. What no one had measured carefully was whether the gap was stable, shrinking, or quietly growing.

That question became the starting point for our recent paper in the Journal of Orthopaedics and Traumatology. The title is deliberately blunt: “Orthopaedic publications receive fewer citations than general medicine articles: a scientometric analysis of temporal trends.” Behind it sits a simple, slightly uncomfortable observation. Citation counts have become the default currency of academic value. By that currency, orthopaedics consistently looks poorer. The paper asks whether this reflects weaker science or a structural feature of how different fields generate and accumulate attention.

The provocation that would not go away

The opening line of the introduction still feels true: “How good is orthopaedic research?” It is deliberately provocative because the question sits at the intersection of careers, funding allocations, and institutional prestige. Most of us who work in the specialty have watched talented colleagues struggle to match the raw citation numbers of peers in broader medical disciplines, even when the methodological quality of the work is comparable. We have also watched evaluation systems continue to treat absolute citation counts as if they were field-neutral.

The reasons for the disparity are not mysterious. Orthopaedics addresses conditions that affect narrower patient populations than cardiovascular disease, diabetes, or cancer. Its methodological culture still leans heavily toward observational cohorts, single-centre series, and technique papers—formats that are rarely citation magnets. The potential citing audience for any given paper is smaller by definition. Citation half-lives in surgical specialties tend to be longer; impact often accumulates slowly. None of this is news. What remained unclear was the trajectory. Had the explosion of orthopaedic publications over the past decade, the rise of open access, digital discovery tools, and accelerating subspecialisation narrowed the gap, or had they made it worse?

We decided to find out by looking at the extreme upper tail of the literature—the 100 most-cited articles in each field in two snapshot years, 2014 and 2024.

A deliberately simple design

The methods were intentionally austere. We used the Web of Science Core Collection and took a single citation snapshot on 19 January 2026 so that every paper, regardless of field or publication year, was measured under identical conditions. No topic keywords were applied. Articles were retrieved solely by publication year and Web of Science subject category—clinical medicine categories for the medicine cohort, the “Orthopaedics” category for the specialty cohort. Only articles and reviews were retained. For each of the four strata (Medicine 2014, Medicine 2024, Orthopaedics 2014, Orthopaedics 2024) we simply took the top 100 records by citation count.

Two metrics mattered. Absolute citations told us about overall impact. Citation velocity—citations per year since publication—allowed fairer comparison between a mature 2014 cohort and a very young 2024 cohort that had been available for citation for at most one year.

The numbers were stark

In 2014, the median citation count among the top 100 medicine articles was 5,055. In orthopaedics it was 288. That is a 17.6-fold difference. By 2024 the medians had fallen, as expected for a younger cohort (720.5 versus 34), but the ratio had widened to 21.2-fold. Citation velocity told the same story: medicine maintained an approximately 17- to 21-fold advantage at both time points.

Within fields, the patterns diverged. Medicine’s citation velocity remained relatively stable between the 2014 and 2024 cohorts (ratio 0.84). Orthopaedics showed a clearer slowdown (ratio 0.69). The most-cited recent orthopaedic papers were accruing citations more slowly in their first year than their counterparts a decade earlier. One plausible explanation is fragmentation: more papers competing for the attention of a citing community that has not grown at the same rate.

The distributional picture added another layer. Medicine’s top 100 were sharply right-skewed. A handful of landmark papers pulled the entire distribution dramatically upward. Orthopaedics was flatter. Citations were spread more evenly across the influential papers. That may look more equitable, but it also means the specialty lacks the extreme citation outliers that dominate aggregate metrics in broader medicine. There is no orthopaedic equivalent of the papers that redefined sepsis management or established the evidence base for statins—not because orthopaedics lacks rigorous work, but because the communities that would cite such advances are smaller and more circumscribed by nature.

What the numbers do not say

It is important to be clear about what this analysis does not measure. We did not examine level of evidence, methodological quality, use of validated outcomes, or clinical relevance. The data say nothing directly about whether the science produced in orthopaedics is better or worse than that produced in general medicine. They describe only citation performance at the extreme upper tail of two fields. What holds for the top 100 may not hold for the average paper. The 2024 cohort is still in its infancy; early citation trajectories are noisy. Web of Science indexing is not perfectly uniform across specialties. All of these caveats matter.

What the data do show is structural. A paper is cited when other researchers read it, find it relevant, and choose to acknowledge it. The size of that potential audience is shaped by the breadth of the topic, the size of the patient population, the number of adjacent journals, and the global density of research groups working on related questions. A rigorous randomised trial comparing two fixation techniques for proximal humeral fractures will almost always have a smaller citing pool than a similarly rigorous trial in cardiovascular risk prevention. That is not a judgment on quality. It is a description of the ecology of attention.

Why the gap still matters

If citation-based metrics continue to be used without field normalisation in hiring, promotion, funding, and ranking decisions, the disadvantage becomes self-reinforcing. Early-career orthopaedic researchers compete against numbers that are systematically harder to reach. Institutions that lean heavily on raw citation counts may undervalue the contribution of surgical specialties. Over time, the disparity can shape what research gets prioritised and who stays in academic orthopaedics.

The findings are not a counsel of despair. They are a call for more sophisticated evaluation. Field-normalised indicators, carefully constructed classification systems, and a broader appreciation of what different kinds of research actually contribute would serve the community better than the blunt instrument of absolute counts. The Leiden Manifesto and related work on responsible metrics have been saying this for years. The numbers in this paper simply make the orthopaedic case more concrete.

A personal note on collaboration

This project brought together colleagues across Germany, India, Italy and the United Kingdom who have spent years thinking about how orthopaedic research is produced, disseminated and valued. Some of us have previously mapped national outputs, journal rankings, and highly cited papers within the specialty. This time the lens was wider: how does the specialty as a whole compare with the broader medical literature over time? The answer turned out to be more sobering than any of us expected, and more stable than we hoped.

The paper does not claim that orthopaedic research is less important. It claims that the current dominant metric systematically under-represents it. In a world that increasingly equates citation volume with scientific value, that distinction is worth stating clearly. The gap is real. It is structural. And on the evidence of the last decade, it is not closing.
