Total Knee ArthroplastyNCT05581563
Clinical and Functional Outcomes of Tourniquet Use in Primary Total Knee Arthroplasty
A study testing total knee arthroplasty(TKA) in people with Total Knee Arthroplasty, run by Mongi Slim Hospital.
Trial summary
Many surgeons choose to perform total knee arthroplasty (TKA) surgery with the aid of a tourniquet. A tourniquet is a device that fits around the leg and restricts blood flow to the limb. There is a need to understand whether tourniquets are safe, and if they benefit, or harm, patients. Read more about this study

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
total knee arthroplasty(TKA)Procedure or surgery
Knee replacement, also called knee arthroplasty or total knee replacement, is a surgical procedure to resurface a knee damaged by arthritis. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap. This surgery may be considered for someone who has severe arthritis or a severe knee injury.
| Study group | Role | What they receive |
|---|---|---|
| tourniquet use | Active comparator | knee replacement surgery with the aid of a tourniquet - a tight band placed around the thigh that restricts blood flow to the knee. Receives: Procedure: total knee arthroplasty(TKA) |
| without tourniquet use | Sham comparator | knee replacement surgery without the aid of a tourniquet - a tight band placed around the thigh that restricts blood flow to the knee. Receives: Procedure: total knee arthroplasty(TKA) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Visual Analogue Scale (VAS)
Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity. Based on the distribution of pain VAS scores in post-surgical patients, mild, moderate, or severe, the following cut points on the pain VAS have been recommended: no pain (0-4 mm), mild pain(5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm).
Measured: Baseline

International Knee Documentation Committee (IKDC) 2000 subjective score The score is interpreted as a measure of function such that higher scores represent higher levels of function and lower levels of symptoms. A score of 100 is interpreted to mean no limitation with activities of daily living or sports activities and the absence of symptoms.

Lysholm score
The Lysholm Scale currently consists of eight items that measure: pain (25 points), instability (25 points), locking (15 points), swelling (10 points), limp (5 points), stair climbing (10 points), squatting (5 points), and need for support (5 points). Every question response has been assigned an arbitrary score on an increasing scale. The total score is the sum of each response to the eight questions and may range from 0-100. Higher scores indicate a better outcome with fewer symptoms or disabilities

Questions about this trial
What is this clinical trial studying?
A study testing total knee arthroplasty(TKA) in people with Total Knee Arthroplasty, run by Mongi Slim Hospital.
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: status not confirmed, as of the sponsor's last update on 14 Oct 2022. 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. Some participants in this study may receive a placebo. 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?
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?
Visual Analogue Scale (VAS) (time frame: Baseline). The study lists 16 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 14 Oct 2022.
