Outcome Measures

Primary Outcomes (1)

  • Evaluation of IKDC Subjective Score using a dedicated evaluation form

    The non-inferiority of the test device group to the control group will be evaluated 12 months after surgery using the IKDC Subjective Score. (maximum score: 100 and minimum score: 0, higher scores mean a better outcome)

    12 months after surgery

Secondary Outcomes (8)

  • Measurement of Tibial Anterior Translation using a measuring device

    12 months after surgery

  • Evaluation of Donor Site Morbidity using a dedicated evaluation form

    1 week, 1 month, 3 months and 6 months after surgery

  • Measurement of Knee Flexion Strength using a measuring device

    3 months, 6 months and 12 months after surgery

  • Evaluation of TEGNER-Activity-Score using a dedicated evaluation form

    6 months and 12 months after surgery

  • Incidence of additional surgery on the affected side

    Through 12 months after surgery

  • +3 more secondary outcomes

Other Outcomes (8)

  • Thigh Circumference

    1 week and 2weeks after surgery

  • Surgery time

    At index procedure

  • Evaluation of IKDC Subjective Score using a dedicated evaluation form

    24 months after surgery

  • +5 more other outcomes

Study Arms (3)

Safety evaluation cohort; CT-ACL001 treatment group

EXPERIMENTAL

An acute safety evaluation group that will receive treatment with the test device without randomization: 7 cases

Device: Anterior cruciate ligament reconstruction

Randomization cohort; CT-ACL001 treatment group

EXPERIMENTAL

Treatment with the test device (test device group): 38 cases

Device: Anterior cruciate ligament reconstruction

Randomization cohort; autologous tendon treatment group

ACTIVE COMPARATOR

Anterior cruciate ligament reconstruction with autologous tendon (knee flexor tendon) (control group): 19 cases

Procedure: Anterior cruciate ligament reconstruction

Interventions

Single-bundle anterior cruciate ligament reconstruction will be performed using the test device. In addition, single-bundle anterior cruciate ligament reconstruction will also be performed in the control group using autologous knee flexor tendons.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Age: 18 years old or older and under 45 years old.
  • Patients with anterior cruciate ligament injury who are candidates for reconstruction surgery.

You may not qualify if:

  • Chronic anterior cruciate ligament injury (injury occurred more than 12 months ago).
  • History of knee surgery, including anterior cruciate ligament surgery on the index side.
  • Complication or history cruciate ligament injury on the opposite side, history of total knee arthroplasty, osteotomy around the knee, or osteosynthesis around the knee on the opposite side.
  • Meniscus injury that requires extensive resection and is impossible to suture on the index side, collateral ligament injury or posterior cruciate ligament injury of 2° or more on the index side.
  • Complication of osteoarthritis of the knee on the index side, KL classification 2° or higher.
  • Complications of cartilage damage that cannot be treated by drilling or microfracture on the index side.
  • Patients with infection in the index knee or inflammatory joint disease such as rheumatoid arthritis.
  • Patients undergoing radiation therapy, chemotherapy, or both.
  • Patients currently receiving treatment with systemic steroids, immunosuppressants, or both.
  • Patients who are allergic to bovine products (e.g. meat).
  • Patients who cannot discontinue returning to sports until 9 months after reconstruction surgery.
  • Pregnant, breastfeeding and possibly pregnant patients.
  • Female patients of childbearing potential and male patients who cannot agree to contraception for at least one year after reconstruction surgery.
  • Patients who participated in other clinical trials within 4 weeks prior to reconstruction surgery.
