Re: Delay in diagnosis and management of adolescent ACL injuries

I am not surprised by the finding that discrepancies exist in the W0 time between individuals. Further studies on this, as suggested in the article [BCMJ 2021;63:211-216], would be helpful. However, I am concerned that the authors’ recommendation that all adolescent patients presenting with an acute hemarthrosis be referred for an MRI will only lengthen the W0 time. These patients will join the ever-ballooning pool of people waiting for unnecessary musculoskeletal MRIs.

It also suggests that the presence of a hemarthrosis is, in fact, identified. In today’s medical climate of COVID-19, precipitated telephone consultations, and Babylonesque primary care that may not be the case.

The paper referenced in Dr Leveille’s article (Ardern CL and colleagues), recommending the need for an MRI, itself references a paper by Kocher MS and colleagues (Am J Sports Med 2001;29:292-296) to support this recommendation. This is perplexing, as the conclusion of that paper is “MRI does not provide enhanced diagnostic utility over clinical examination.”

Having recently treated two adolescents with locked knees who presented late due to the wait for unnecessary MRIs, I would advocate for Dr Leveille and colleagues’ other recommendation: the urgent referral of all adolescents with an acute knee hemarthrosis (swollen knee) from the primary care or urgent care provider.

Above is the information needed to cite this article in your paper or presentation. The International Committee of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally accepted citation style for scientific papers:
Halpern SD, Ubel PA, Caplan AL, Marion DW, Palmer AM, Schiding JK, et al. Solid-organ transplantation in HIV-infected patients. N Engl J Med. 2002;347:284-7.

About the ICMJE and citation styles

The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.

An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.

BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:

  • Only the first three authors are listed, followed by "et al."
  • There is no period after the journal name.
  • Page numbers are not abbreviated.
