Clinical Trial Summary

Pediatric ACL: Understanding Treatment Outcomes (PLUTO) is a multi-center, prospective cohort study. Specific aims of PLUTO are to evaluate the safety and comparative effectiveness of non-operative treatment, as well as four operative treatments including (1) transphyseal ACL reconstruction (2) partial transphyseal ACL reconstruction, (3) physeal-sparing epiphyseal ACL reconstruction using the Anderson technique, and (4) physeal-sparing ACL reconstruction using the Micheli/Kocher technique in prepubescent and pubescent skeletally immature patients.

Description:

Anterior Cruciate Ligament (ACL) injuries are being seen with increased frequency in pediatric and adolescent patients. The management of these injuries is controversial and includes nonoperative treatment and operative treatment with various surgical techniques. Pediatric ACL: Understanding Treatment Outcomes (PLUTO) is a multi-center, prospective cohort study. Specific aims of PLUTO are to evaluate the safety and comparative effectiveness of non-operative treatment, as well as four operative treatments including (1) transphyseal ACL reconstruction (2) partial transphyseal ACL reconstruction, (3) physeal-sparing epiphyseal ACL reconstruction using the Anderson technique, and (4) physeal-sparing ACL reconstruction using the Micheli/Kocher technique in prepubescent and pubescent skeletally immature patients. Accrual will take place over eight years at 9 pediatric sports medicine centers. Post-treatment outcome assessment will be performed at 6-9 months, 1 year, and 2, 5, and 10 years after treatment , including functional outcome, activity level, health-related quality of life, graft survivorship, knee stability, knee motion, and growth disturbance.

Intervention

Other:
• Non-operative treatment group will undergo standardized treatment which will include rehabilitation, bracing and certain activity restrictions
The non-operative treatment group will undergo standardized treatment which will include rehabilitation, bracing and certain activity restrictions.

Procedure:
• Surgical technique: Transphyseal reconstruction
Study physicians will have the option to treat ACL injuries operatively or non-operatively, according to their standard of care. However, once the decision is made to manage the injury operatively or non-operatively, the physician must follow the appropriate standardized treatment protocol developed for the study. The operative treatment protocol will include standardized surgical techniques for transphyseal reconstruction with soft tissue graft and metaphyseal fixation.
• Surgical technique: Partial transphyseal reconstruction
Study physicians will have the option to treat ACL injuries operatively or non-operatively, according to their standard of care. However, once the decision is made to manage the injury operatively or non-operatively, the physician must follow the appropriate standardized treatment protocol developed for the study. The operative treatment protocol will include partial transphyseal reconstruction (tibial transphyseal and femoral epiphyseal) with soft tissue graft.
• Surgical technique: Physeal sparing reconstruction by the Anderson method
Study physicians will have the option to treat ACL injuries operatively or non-operatively, according to their standard of care. However, once the decision is made to manage the injury operatively or non-operatively, the physician must follow the appropriate standardized treatment protocol developed for the study. The operative treatment protocol will include standardized surgical techniques for physeal sparing epiphyseal reconstruction with soft tissue graft (Anderson technique).
• Surgical technique: Physeal sparing reconstruction by the Micheli/Kocher method
Study physicians will have the option to treat ACL injuries operatively or non-operatively, according to their standard of care. However, once the decision is made to manage the injury operatively or non-operatively, the physician must follow the appropriate standardized treatment protocol developed for the study. The operative treatment protocol will include physeal-sparing with Iliotibial band combined extra-articular and intra-articular reconstructions (Micheli/Kocher Technique).
