Soft-tissue Quadriceps Autograft ACL-reconstruction in the Skeletally-immature vs. Hamstrings (SQuASH)
ACL - Anterior Cruciate Ligament Rupture
About this trial
This is an interventional treatment trial for ACL - Anterior Cruciate Ligament Rupture focused on measuring Autograft, Soft-tissue hamstring, Quadriceps Tendon
Eligibility Criteria
Inclusion Criteria:
- Males and females aged 10-18 years.
- History, physical exam, and magnetic resonance imaging (MRI) or arthroscopic image confirmation of ACL insufficiency.
- Suitable for anatomic, single-bundle arthroscopic-assisted ACL reconstruction.
- Complete or partial transphyseal ACL femoral and tibial tunnel drilling/reconstruction techniques.
- Patient involved in sport (competitive and/or recreational level) prior to injury.
- Patient and parent/guardian speak, read, and understand the language of the clinical site.
- Patient and parent/guardian provide informed consent.
Exclusion Criteria:
- Evidence (i.e. radiographic and/or arthroscopic) of International Cartilage Repair Society (ICRS) Cartilage Lesion Classification System Grade 2 and higher osteoarthritis.
- Tibial eminemence/spine fractures.
- Concomitant collateral, posterior cruciate, and/or cartilage pathology.
- Previous knee surgery in the affected or contra-lateral knee.
- Previous distal femur and/or proximal tibial/fibular physeal injury in the affected or contra-lateral knee.
- Allograft or allograft-augmentation of the ACL reconstruction.
- ACL reconstruction utilizing synthetic grafts.
- Primary ACL repair.
- Generalized ligamentous laxity and/or hypermobility (i.e. Beighton Criteria ≥ 4/9), given statistically significant higher failure rates (24% vs. 7.7%) and inferior subjective outcomes in this population.
- Significant medical co-morbidities (requiring daily assistance for activities of daily living).
- Patient, parent/guardian, and/or clinical investigator believe the patient will have difficulty maintaining follow-up.

Active Comparator
Active Comparator
Soft-tissue hamstring
Quadriceps tendon
All patients in the study will undergo arthroscopic-assisted, single-bundle, complete transphyseal, anatomic primary ACL reconstruction at the discretion of the surgeon, considering the individual patient's age, physeal status, and anticipated years of growth remaining to skeletal maturity. Patients in this arm will undergo soft-tissue autograft reconstruction using hamstrings (i.e. semitendinosus and/or gracilis) grafts. Grafts will be secured on the femur and tibia according to surgeon preference, given literature demonstrating no clear superior method for graft fixation.
Patients in this arm will undergo soft-tissue autograft reconstruction using all-soft-tissue quadriceps (i.e. full or partial thickness) grafts. Grafts will be secured on the femur and tibia according to surgeon preference, given literature demonstrating no clear superior method for graft fixation.
