Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Physical Therapy plus Protein Supplement

Participants will be randomized to the protein supplementation group, PROT, and will receive education from a dietary counselor on how to monitor protein intake using a smartphone app.

Group Type EXPERIMENTAL

Protein (PROT)

Intervention Type 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.

Physical Therapy Control

Participants will be randomized to the enhanced-care control group, CONT, and will receive education from a dietary counselor on how to monitor protein intake using a smartphone app.

Group Type ACTIVE_COMPARATOR

Control (CONT)

Intervention Type OTHER

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

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Participants with a complete ACL tear and received a hamstring autograft ACL repair surgery (within 8 months of injury) and plan to complete physical therapy and follow up treatment with WFBH at D1 outpatient rehabilitation
* Subjects must have a smartphone capable of running the nutrition tracking app (My Fitness Pal)

Exclusion Criteria

* Subjects must not have other ligamentous involvement, or complications during the surgical procedure.
* They must not have had a concurrent meniscal repair (debridement is acceptable).
* They must not have post-operative limitations that interfere with rehabilitation.
* Patients determined by the referring surgeon to be poor candidates for the study for any medical (including history of eating disorder, phenylketonuria, maple syrup urine disease, food allergies, lactose intolerance, kidney or liver disease) or other reasons that deem them inappropriate to complete the intervention (driving distance from facility, work schedule that prohibits therapy treatments, dietary restrictions) will be excluded.
* Females who are pregnant will not be permitted in the study.
