This podcast episode features a conversation between Jake Tuura and Derek Garza, a licensed physical therapist, focusing on ACL injuries, rehabilitation strategies, and the different types of tendon grafts used in ACL reconstruction surgery (autograft vs. allograft, quad, patellar, hamstring). The discussion delves into the intricacies of graft selection, post-surgical management, rehabilitation timelines, and the importance of plyometrics in achieving a successful return to sport.
Graft Selection and Healing: The choice of graft (autograft, allograft, quad, patellar, hamstring) significantly impacts rehabilitation timelines and potential risks. Autografts weaken in the first 6-12 weeks post-surgery, while allografts have a slower cellular repopulation. Each graft type has unique healing characteristics affecting strength recovery.
Early Rehabilitation Focus: Early rehab prioritizes regaining knee extension and quadriceps function. Addressing arthrogenic muscle inhibition (AMI) through swelling management is crucial. The podcast emphasizes the importance of prioritizing knee extension over flexion in early stages.
Plyometrics and Return to Sport: Plyometric exercises are introduced gradually, starting with low-impact movements and progressing to more demanding exercises as the graft matures. The importance of deceleration training is stressed. A crucial point is avoiding premature return to sport, as it significantly increases re-injury risk.
Knee vs. Hip Strategy: Patients often exhibit a "hip strategy," avoiding knee loading, hindering full recovery. Proper assessment and intervention to encourage knee loading are essential.
Education Gaps in ACL Rehab: The podcast highlights significant education gaps in physical therapy schools regarding plyometrics and advanced ACL rehabilitation techniques. The speakers advocate for improved training and collaboration between physical therapists and strength coaches.
What are the specific differences in the recommended plyometric progressions for each graft type (quad, patellar, hamstring)? The transcript doesn't detail specific, distinct plyometric progressions for each graft type. However, it mentions that deeper, more impactful movements might be used with patellar and quad tendon grafts compared to hamstring grafts due to the latter's sensitivity to eccentric loading. The progression is individualized and depends on the patient's response and the healing stage of the graft.
What are the specific metrics Derek Garza uses to assess quadriceps strength and limb symmetry, and what thresholds indicate readiness for plyometric exercises? Derek Garza uses a dynamometer (specifically the T-Index) to measure peak torque, comparing it to body weight to assess limb symmetry and quadriceps strength. For plyometrics, he aims for 1.6 to 1.8 Newton meters per kilogram before starting low-level plyos and roughly 70-80% of 3.0 Newton meters per kilogram for return-to-run.
What are the key indicators Derek Garza looks for to identify a patient utilizing a "hip strategy" versus a "knee strategy" during movement assessments? The transcript doesn't explicitly list specific indicators, but it implies that observation of movement quality during exercises like single-leg hops, triple-leg hops, and crossover hops reveals whether a patient compensates by overusing hip muscles ("hip strategy") rather than engaging the knee properly ("knee strategy"). Video analysis and visual observation are key components in this assessment.
What specific educational resources or changes in physical therapy curriculum does Derek Garza suggest to address the identified knowledge gaps in ACL rehabilitation? The transcript doesn't offer specific educational resources, but Derek Garza advocates for increased emphasis on plyometrics and advanced strength training techniques within physical therapy curricula. He suggests hands-on experience and collaboration with strength coaches to bridge the gap between theoretical knowledge and practical application. He also highlights the inadequacy of some current research, stating some research articles are "worthless" due to insufficiently challenging exercises used in studies.
