Comparison of Functional Outcome Between BQT and SBHT ACL Reconstruction
A study testing Bone Quadriceps Tendon (BQT) arthroscopic-assisted ACL reconstruction and Single-Bundle Hamstring Tendon (SBHT) arthroscopic-assisted ACL reconstruction in people with Sports Injury and Anterior Cruciate Ligament Rupture, run by Universitas Indonesia.
Trial summary
ACL rupture has a high morbidity in productive-age population. The increasing incidence and proper management has become a point of interest in the musculoskeletal sport injury. Choosing the best graft has become the main focus in searching for a better outcome regarding ACL reconstruction in these patient population. Read more about this study

About this study
Official title: Comparison of Functional Outcome Between Bone Quadriceps Tendon (BQT) and Single-Bundle Hamstring Tendon (SBHT) Autograft in Arthroscopic-assissted Anterior Cruciate Ligament Reconstruction: a Prospective Cohort Study
ACL rupture has a high morbidity in productive-age population. The increasing incidence and proper management has become a point of interest in the musculoskeletal sport injury. Choosing the best graft has become the main focus in searching for a better outcome regarding ACL reconstruction in these patient population. Currently, single bundle hamstring tendon (SBHT) autograft was preferred in Asian population compared to bone quadriceps tendon (BQT) autograft. However, there are some problems such as smaller size, as well as diameter, of SBHT. This study is focused on evaluation of the clinical outcome between BQT and SBHT in arthroscopic-assisted ACL reconstruction patients.
Read the detailed description
In this prospective cohort study, 30 subjects were divided into 2 groups (BQT and SBHT). Sampling was taken between February 2016-2017 (1 year) in one orthopaedic center. The instruments used for evaluation are rolimeter and PRO questionnaires (IKDC, Tegner-Lysholm, and KOOS) with data mining between 1 month, 3 months, and 6 months post operation.
To obtain a valid and accountable research data, the investigators collected the information based on 2 parameters and then crosschecked the results.
After clinical data was obtained, the investigators translate the results into a statistical data using SPSS ver.24 and simplified the data for national registry and academic purposes.
According to previous studies, and research hypothesis, functional outcome of patient undergoing arthroscopic-assisted ACL reconstruction is better in BQT group compared to SBHT group, both in subjective and objective parameters given.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Bone Quadriceps Tendon (BQT) arthroscopic-assisted ACL reconstructionProcedure or surgery
New intervention method deployed in Indonesia to gain better clinical outcome for ACL--deficient patients requiring surgical treatment
Single-Bundle Hamstring Tendon (SBHT) arthroscopic-assisted ACL reconstructionProcedure or surgery
Comparator for New Reconstruction Technique
| Study group | Role | What they receive |
|---|---|---|
| BQT Group | Active comparator | Procedure on this arm = bone quadriceps tendon reconstruction Receives: Procedure: Bone Quadriceps Tendon (BQT) arthroscopic-assisted ACL reconstruction |
| SBHT Group | Other | Procedure on this arm = single-bundle hamstring tendon reconstruction Receives: Procedure: Single-Bundle Hamstring Tendon (SBHT) arthroscopic-assisted ACL reconstruction |
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes (Improvement) of Rolimeter Measurement After Procedure
- Rolimeter measurement is the objective outcome expected in this study
- This device was calibrated and tested prior to the usage in the study
- Literature review --> no significant difference between KT1000/2000 and rolimeter for measuring antero-posterior translation of the knee joint
Measured: Measurement in 1 year after operation
Changes (Improvement) of PRO Questionnaire After Procedure
- We use three different PRO to make an accountable subjective outcome
- No standard PRO questionnaire for ACL cases; we used three to be able to triangulate the mean subjective outcome
- Rationale for using three PRO : these PROs were rapidly used in other similar studies around the world, had good and reliable results, and contains categoric and numeric data for statistical computation and interpretation
Measured: PRO was taken in a period of 1 year after surgical procedure

Questions about this trial
What is this clinical trial studying?
A study testing Bone Quadriceps Tendon (BQT) arthroscopic-assisted ACL reconstruction and Single-Bundle Hamstring Tendon (SBHT) arthroscopic-assisted ACL reconstruction in people with Sports Injury and Anterior Cruciate Ligament Rupture, run by Universitas Indonesia.
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 3 inclusion and 4 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: finished, as of the sponsor's last update on 2 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.
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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Changes (Improvement) of Rolimeter Measurement After Procedure (time frame: Measurement in 1 year after operation). The study lists 2 primary outcomes in all. 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 NCT04536246, which also lists 26 linked publications.
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 Sep 2020.
