About this study
The purpose of this study was to investigate whether intraarticular administration of tranexamic acid could reduce hemarthrosis and postoperative pain in patients following anterior cruciate ligament reconstruction. The hypothesis of the study was that patients treated with intraarticular tranexamic acid would have significantly less postoperative hemarthrosis and less pain in the early phase of the rehabilitation process compared with those without intraarticular tranexamic acid .
Read the detailed description
Intervention Based on the previous studies, intraarticular administration with concentration of 30mg/mL was selected. The operation room nurses prepared 3g tranexamic acid in 100 mL of saline solution during operation. After finishing surgical wound suture and orthopaedic surgeons related to this study left operation room, the orthopaedic residents who were not involved in the postoperative evaluation administered tranexamic acid solution through suprapatellar pouch before tourniquet release in patients in the treatment group. The control group did not receive any solution. intraarticular drain was not inserted in all patients.
Outcome Demographic variables (age, sex, body mass index, and time from injury to surgery), clinical outcomes and surgical records including operative time, bleeding amounts, meniscus and cartilage lesions were collected by an independent orthopaedic resident. Primary outcome was a blood loss calculated based on hemoglobin balance. We assumed that blood volume in ml on the second day after surgery was the same as that before surgery. Blood volume was estimated according to the method of Nadler and colleagues taking sex, body mass and height into account. The loss of Hemoglobin was then estimated according to the formula.
Hemoglobin loss=Blood volume*(Hemoglobin concentration before surgery - Hemoglobin concentration after surgery)*0.001+total amount of allogenic hemoglobin transfused
The secondary outcome was an extent of pain measured by a visual analog scale at a consistent time in the afternoon of postoperative day 1 (PD 1) and for the next 4 day.The pain visual analog scale is a numeric response on a scale from 0 to 10, with 0 denoting no pain and 10 signifying severe pain. The other secondary outcomes included mid-patellar circumference at postoperative day 2 and day 5 and knee range of motion after 6 weeks from operation, which were measured by an independent orthopaedic fellow. The patellar circumference was measured transverse axis of the patella center to evaluate intra-articular effusion. To minimize inter-observer variance of the patellar circumference, we considered the difference between the preoperative and the postoperative results. The range of motion was documented as the extension and flexion degrees using an orthopaedic goniometer.

What is being measured
The primary outcome is the main question the study is designed to answer.

Primary outcome was a blood loss calculated based on hemoglobin balance. We assumed that blood volume in ml on the second day after surgery was the same as that before surgery. Blood volume was estimated according to the method of Nadler and colleagues taking sex, body mass and height into account. The loss of Hemoglobin was then estimated according to the formula.

Measured: 2 days

Measured: 1 day and 5days

A Phase 4 study testing intraarticular administration of tranexamic acid in people with Anterior Cruciate Ligament Rupture, run by Korea University Guro Hospital at 1 site in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 2 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
blood loss (time frame: 2 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04042688, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Aug 2019; AzTrials last refreshed its copy on 7 Nov 2026.
