Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The first stage of the research will be the qualification of the patient for the ACL reconstruction performed by the orthopedic surgeon.
The second stage of postoperative therapy will be dividing patients into two groups and randomly assigning each of them on the first day after the reconstruction a device emitting a magnetic field (the assignment of the device will be based on a simple randomization using a coin toss - the obverse - the patient received the A device, the reverse - the patient received the apparatus B). Neither the patient nor the investigators will know which device emits a magnetic field.
For the next 11 days, each patient will have a magnetic field performed by the physiotherapist. The device is a knee brace that is strapped onto the participant. The magnetotherapy treatment will be performed daily at the same time by the same therapist. Patients will use the device for 30 minutes, and the magnetic field parameters in both devices will be the same - 3mT and 100Hz.
The third stage of the research will be a functional examination including measurement of the lower limb circumferences (measurement by the knee and thigh (10 cm from the patellar base) and range of knee joint motion and assessment of knee joint function using the Lysholm scale.
The first examinationof the lower limb circumferences will be made before the start of therapy with a magnetic field, and then every day for a period of 11 days, each time after the treatment with a magnetic field. The range of motion of the knee and the assessment of joint function will be evaluated twice - before and after the end of therapy with a magnetic field.
Any changes in the progress of the intervention will be made by direct supervision of the physiotherapist.
During the magnetic field application, patients of both groups will not perform any exercises of the operated joint, they will move on crutches and apply cooling the joint with ice cubes (2x daily for 15 min).
Intervention adherence will be assessed by direct supervision
Intervention code [1] 314555 0
Treatment: Devices
Comparator / control treatment
The control group will have the same intervention, because until the tests are completed, it will not be known which device emits a magnetic field.
Placebo device is the same to the intervention device except that it does not provide a magnetic field,
Control group
Placebo

3. A voluntary consent of the patient to participate in the study.
Minimum age
18 Years
Maximum age

Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Absenteeism in magnetic field treatments.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After the procedure, each patient will be randomly assigned a device emitting a magnetic field (the assignment of the device will be based on a simple randomization using a coin toss - the heads- the patient received the A device, the tails- the patient received the B device). Neither the patient nor the investigators will know which device emits a magnetic field.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using coin-tossing.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s

Statistical methods / analysis
Statistical analysis will be developed using Statistica 10 software. Methods of descriptive statistics will be used to present the results in the form of tables containing arithmetic means, standard deviation, minimum and maximum values.
The first stage of the analysis will be the assessment of the distribution of observed values of the lower limb circuits using the Shapiro-Wilk test. Then, the observed values will be checked for equality of variance. For this purpose, the Fisher-Snedecor test will be used.
In order to compare the distribution of variables between particular groups of the lower limb study in the following days, the Student's t-test for independent samples will be used. In order to determine the change in time of the size of the edema within a given group, an analysis of variance for a dependent group (repeated measurements) using the post-hoc tests (Tukey's test) will also be performed. The significance level of p> 0.05 will be assumed.
