Brief Summary:
Anterior cruciate ligament (ACL) tears are among the most frequent traumatic knee injuries that occur in physically active individuals. Despite advances in minimally invasive surgical reconstruction techniques and aggressive rehabilitation, this atrophy and loss of strength can persist even after patients return to full activity and can place them at considerable risk for re-injury and developing osteoarthritis (OA). The design of new therapeutic interventions to prevent muscle atrophy is needed to advance the care of patients who suffer from ACL injuries. The growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis plays an important role in promoting muscle growth and protecting muscle from atrophy. While GH therapy has shown promise in protecting immobilized muscle from various models of disuse atrophy, it remains unknown whether GH can help to restore strength and protect against the loss in strength that occurs after ACL tear. GH therapy may help to accelerate the safe return to play of patients that suffer ACL tears, and help to prevent the long-term OA and reduction in quality of life that occur after these traumatic knee injuries.

Arm Intervention/treatment
Active Comparator: Somatropin
Somatropin of rDNA origin
Drug: Somatropin
GH dose will be calculated by nomogram estimation of body surface area, and will be administered via subcutaneous injection in the abdominal area twice per day (BID) at a dose of 0.5mg GH per body surface area (BSA) in m2 (0.5mg/m2). Patients will begin GH treatment one week prior to surgery and will continue through 5 weeks after surgery. On the day of surgery, patients will not take GH, but otherwise patients will take GH every day over this 6 week period.

Placebo Comparator: Placebo
A placebo vehicle that contains somatropin diluent but no active hormone.
Drug: Placebo
A placebo diluent that will be administered via subcutaneous injection in the abdominal area twice per day (BID) at a dose of the equivalent concentration of 0.5mg GH per body surface area (BSA) in m2 (0.5mg/m2). Patients will begin treatment one week prior to surgery and will continue through 5 weeks after surgery. On the day of surgery, patients will not take medication, but otherwise patients will take medication every day over this 6 week period.

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Males between the ages of 18 and 35
  • Have acute unilateral complete ACL tears with or without bucket handle medial meniscus tears that occurred within the past 6 months
  • Consent to undergo an ACL reconstruction by an orthopaedic surgeon using a patellar tendon or hamstring autograft
  • Will be performing supervised post-operative rehabilitation at UMHS MedSport at Dominos Farms

Exclusion Criteria:

  • Patients who are undergoing a revision ACL reconstruction
  • Had a previous injury to the involved knee
  • Have an allergy to recombinant GH
  • Have a BMI<20 or >35
  • Have a growth disorder of bones or connective tissue, type 1 diabetes mellitus, type 2 diabetes mellitus, or who have a history of carpal tunnel syndrome, trigger finger, myopathy, cancer, endocrine disorder, hypertension or rheumatologic disorder.
  • Systolic blood pressure >140mm Hg or diastolic blood pressure >90mm Hg, or with resting heart rate >110 BPM or <40 BPM at screening.
  • Additionally, because GH is currently listed as a banned substance by the World Anti-Doping Agency (WADA), National Collegiate Athletics Association (NCAA) and most professional sports agencies, we will exclude patients who are current collegiate, professional or elite athletes.
