Eligibility Criteria

Inclusion

  • INCLUSION CRITERIA
  • In order to be eligible to participate in this study, an individual must meet all of the following criteria:
  • 18-55 years of age
  • Complete ACL tear as confirmed by MRI
  • Selected surgical treatment of ACL injury
  • Believed to be a surgical candidate for ACL reconstruction by treating physician
  • Time from injury to surgery is ≤50 days
  • Stated willingness to comply with all study procedures for the duration of the study, including lifestyle, activity, and sports restrictions
  • Provision of signed and dated informed consent form
  • EXCLUSION CRITERIA AT PRE-OPERATIVE EXAM
  • An individual who meets any of the following criteria, either during a pre-operative exam or during intraoperative arthroscopic evaluation, will be excluded from participation in this study:
  • Any prior ACL surgery on affected knee (except simple arthroscopy for plica, debris removal, or diagnosis)
  • Any prior ACL surgery on unaffected knee (except simple arthroscopy for plica, debris removal, diagnosis or partial meniscectomy)
  • Confirmed or suspected contralateral ACL tear
  • ACL tear found to be only partial and the treating physician feels it does not require surgery because it is "stable"
  • Diagnosis of posterolateral corner injury (complete lateral collateral ligament tear, biceps femoris tendon avulsion, arcuate ligament tear, popliteus ligament tear) that requires concurrent or staged surgical treatment
  • Diagnosis of Grade III medial collateral injury that requires concurrent or staged surgery
  • Insufficient ACL tissue on MRI
  • Diagnosis of complete patellar dislocation
  • Diagnosis of complete patellar tendon or quadriceps tear
  • Obesity with a BMI ≥45
  • Does not speak or understand English
  • Daily smoking (occasional or social use is accepted if smoking ≤ 3 days/ week and ≤ 5 cigarettes/day)
  • Documented history of illicit drug or alcohol abuse (except for recreational use of marijuana)
  • Inability to take oral medications
  • Use of intra-articular corticosteroids in the affected knee within last 6 months
  • Chronic use of corticosteroids for treatment of an autoimmune disorder such as lupus, rheumatoid arthritis, etc. (maintenance or rescue inhaler for asthma is allowed)
  • History of prior infection in knee
  • History of chemotherapy treatment
  • History of sickle cell disease
  • History of anaphylaxis, requiring a documented medical intervention
  • Any condition that, in the opinion of the investigator, could affect healing (e.g., diabetes, inflammatory arthritis, etc.)
  • Pregnancy or lactation
  • Known allergic reactions to meat products or collagen
  • Known allergy to bovine collagen, bovine gelatin, or other bovine products
  • Known adverse reaction to any bovine product
  • Febrile illness within 7 days
  • Treatment with another investigational drug or other intervention, either concurrently or previously, that would interfere with surgical healing
  • Not considered by treating physician to be a good research candidate
  • EXCLUSION CRITERIA AT INTRAOPERATIVE ARTHROSCOPIC EVALUATION
  • Time from injury to surgery has exceeded 50 days
  • No ACL tear found upon arthroscopic inspection
  • ACL tear found to be only partial, with normal pivot shift and endpoint, and does not require surgery
  • Displaced bucket handle meniscal injury requiring repair
  • Diagnosis of full-thickness chondral injury of Grade 3 or 4, or that requires more than microfracture (i.e., osteochondral autograft transplant), on either condyle
  • Unrecognized lateral or medial sided Grade 3 ligamentous injury that requires concurrent or staged surgery
  • Tibial stump length is \< 1cm
  • Tibial footprint attachment is \< 50% intact
  • Any other reason the ACL stump should be deemed irreparable (e.g., tissue quality too poor to hold suture)
