Abstract

Background:

The use of tranexamic acid (TXA) in total knee arthroplasty (TKA) has shown good results. Bleeding may cause local complications consequently greater pain and reduced function postoperatively. No study has related the use of TXA to these facts.

Objective:

The aim was to evaluate the effects of TXA haemoglobin, Western Ontario and McMaster Universities Index (WOMAC), pain intensity and flexion gain after TKA.

Methods:

43 patients were randomized and then underwent TKA. TXA was applied to 22 of these patients before closure of the joint capsule. Haemoglobin measurements (mg/dL) were taken preoperatively and 24 and 48 hours after surgery. The WOMAC questionnaire and pain visual analogue scale (VAS) were applied, and flexion gain was measured up to the second postoperative month. Statistical analysis compared the results to determine whether there were differences between the groups for each of the evaluated times.

Results:

There were differences in favour of the drug 48 hours postoperatively for the haemoglobin variable (p = 0.01), in pain evaluation, 24 and 48 hours, postoperatively (p < 0.01) and in flexion gain, 24 hours after surgery (p = 0.03). There were no significant differences between the groups in the haemoglobin evaluation 24 hours postoperatively, in pain assessment 7 days, 21 days and 2 months, postoperatively, in flexion gain 48 hours, 7 days, 21 days and 2 months, postoperatively and in WOMAC after 2 months.

Conclusion:

In addition to reducing bleeding, topical TXA improved pain and increased flexion gain in the first hours after TKA.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."


Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."


Hubert Wolterbeek
