About this study

Official title: The Effects of Providing Protein and Nutritional Guidance on Healing Times After ACL Surgery

Protein supplementation may promote increases in strength and hypertrophy in the context of resistance training (RT) and reduce markers of inflammation, while sufficient levels of protein are necessary for healing certain wounds and maintenance of muscle mass in a protein depleted state. Protein supplementation could be useful to improve clinical outcomes.

Read the detailed description

Protein supplementation may promote increases in strength and hypertrophy in the context of resistance training (RT) and reduce markers of inflammation, while sufficient levels of protein are necessary for healing certain wounds and maintenance of muscle mass in a protein depleted state. Despite this, no studies have investigated the role of protein provision in the context of physical therapy (PT) or musculoskeletal rehabilitation, including following surgical interventions. Survey data of Americans in the highest protein consuming age range (19-30 year old consuming 91 g/kg body weight/day), show they have an adequate protein intake to maintain nitrogen balance at baseline (85 g/kg). However, if patients under consume protein, as apparent in older adults (mean intake of 66 g/kg) these individuals will require more during times of tissue healing or could benefit with more in attempting to build back their strength through RT or PT. Thus, protein supplementation could be useful to improve clinical outcomes.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Protein (PROT)Dietary supplement

    Participants will receive Combat Protein Powder made by MusclePharm in an amount sufficient to take 80g daily until their next visit. They will be encouraged to ingest 40 g after exercise and 40 g before bed which will partly comprise their daily goal. They will be educated on the concept of complete high quality proteins, and that some proteins can facilitate muscle growth greater than others. Additionally, they will receive meal plan ideas and shopping tips that will facilitate healthy and economical protein consumption up to or beyond their daily goal.

  • Control (CONT)Other

    Instructed not to alter their diet based on the app, and to continue to eat as they normally would.

What is being measured

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

  1. Percentage of individuals that complied with treatment/intervention

    Compliance among treatment group in meeting 2 g/kg protein goal as measured by protein tracking app and in protein supplements provided will be measured.

    Measured: up to 6 months

  2. Percentage of frequency individuals successfully used the protein tracking app

    Compliance in usage of protein tracking app will be recorded. The number of days they logged in and recorded their intake vs. total potential days to provide % value of diet protein compliance.

    Measured: up to 6 months

  3. Percentage of physical therapy visits attended by individuals

    Compliance in physical therapy will be recorded.

    Measured: up to 6 months

  4. Percentage counseling sessions attended by individuals

    Compliance in attending nutritional counseling sessions will be recorded.

    Measured: up to 6 months

Secondary outcomes (4)
  1. Single Leg Hop Test

    Functional healing time based on single leg hop test. The distance the participant hopped on one leg will be recorded and measured in centimeters. This will be done three times and an average will be given.

    Measured: baseline and up to 6 month

  2. Six Meter Timed Hop Test

    Functional healing time based six meter timed hop test. The time it took the participant to hop six meters on foot will be measured and recorded.

    Measured: baseline and up to 6 month

  3. Change in strength in leg flexion and extension

    Strength in leg flexion and extension, as measured by Biodex machine

    Measured: baseline and up to 6 month

  4. Change in muscle hypertrophy

    depth of vastus medialis as measured at each nutritional advising appointment with counselor via ultrasound and thigh circumference.

    Measured: baseline and up to 6 month

Questions about this trial

What is this clinical trial studying?

A study testing Protein (PROT) in people with ACL Injury, run by Wake Forest University Health Sciences.

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 2 inclusion and 5 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: withdrawn, as of the sponsor's last update on 2 Aug 2021. 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 was withdrawn before enrolling participants, so there are no results.

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?

Percentage of individuals that complied with treatment/intervention (time frame: up to 6 months). The study lists 4 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 NCT03614351, which also lists 28 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 Aug 2021.
