Trial Summary

What is the purpose of this trial?

This clinical trial evaluates interventions to maximize muscle function and improve cartilage health following anterior cruciate ligament reconstruction. Improving muscle function may improve patient outcomes, improve joint mechanics, and potentially serve as a prevention approach for post-traumatic knee osteoarthritis. Knee osteoarthritis (OA) is a disabling disease that carries a substantial burden to society and to the individual affected.

Eligibility Criteria

This trial is for individuals with a complete ACL rupture who are scheduled for ACL reconstruction at the University of Michigan. Participants must be willing to follow the study's procedures and have an autograft procedure. Pregnant women, those planning pregnancy, patients with accompanying bony fractures or knee dislocations, or previous knee surgeries cannot join.

Inclusion Criteria

I had ACL reconstruction using my own tissue.
I am scheduled for ACL reconstruction surgery at the University of Michigan.
I have a completely torn ACL recently.

Treatment Details

Interventions

  • Eccentric Exercise (ECC)
  • Eccentric Exercise (ECC) placebo
  • Neuromuscular Electrical Stimulation (NMES)
  • Neuromuscular Electrical Stimulation (NMES) placebo
Trial Overview The MiACLR trial is testing whether Neuromuscular Electrical Stimulation (NMES) and Eccentric Exercise (ECC), along with their placebos, can improve muscle function and cartilage health after ACL surgery to prevent post-traumatic knee osteoarthritis.
Participant Groups
2Treatment groups
Experimental Treatment
Placebo Group
Group I: NMES+ECCExperimental Treatment2 Interventions
Neuromuscular electrical stimulation (NMES) and Eccentric Exercise (ECC). Patients randomized to the NMES+ECC group will first receive NMES for 2x/week for 8 weeks, beginning at the first post-operative visit. Beginning at 9 weeks after anterior cruciate ligament reconstruction (ACLR) patients will begin to receive eccentric exercise 2x/week for an additional 8 weeks. For NMES, patients will have electrical stimulation delivered to their quadriceps. Fifteen isometric actions lasting 10 seconds each will be elicited during each session. For eccentric exercise, patients will train for 4 sets of 10 repetitions. This group will also receive standard of care ACL rehabilitation alongside the study interventions.
Group II: NMES placebo + ECC placeboPlacebo Group2 Interventions
Neuromuscular electrical stimulation (NMES) placebo + Eccentric Exercise (ECC)placebo arm. Patients randomized to the NMES placebo + ECC placebo group will first receive NMES placebo for 2x/week for 8 weeks, beginning at the first post-operative physical therapy visit. Beginning at 9 weeks after anterior cruciate ligament reconstruction (ACLR) patients will begin to receive an eccentric exercise placebo 2x/week for 8 weeks. For the NMES placebo, patients will have NMES placebo delivered to their quadriceps 2x/week for 8 weeks beginning at the first post-operative visit. Fifteen isometric actions lasting 10 seconds each will be elicited during each session. For the eccentric exercise placebo, patients will begin to receive eccentric exercise two times per week for 8 weeks. Patients will train for 4 sets of 10 repetitions.
