Think Outside the Block: Rehabilitation Continuum After ACL Reconstruction with Adaptive Macro-Blocks-A Narrative Review.

Background: Conventional rehabilitation after anterior cruciate ligament reconstruction often follows a rigid, phase-based model. This structure may overlook individual differences in healing, neuromuscular control, and psychological readiness, leading to low return-to-sport rates and a high risk of reinjury. Methods: This narrative review proposes a flexible rehabilitation framework based on overlapping progression blocks. Inspired by principles of strength and conditioning, motor learning, and cognitive training, this model emphasizes continuous, individualized development instead of fixed timelines. Results: The proposed model integrates essential components-such as joint mobility, muscle activation, motor control, and psychological factors-throughout the entire recovery process. Functional testing is redefined as a dynamic and ongoing diagnostic tool that helps clinicians identify areas needing further development, rather than acting as a simple pass/fail gateway. Progression is guided by demonstrated readiness rather than time or phase completion. Conclusions: Rehabilitation using adaptive, overlapping progression blocks offers a more holistic and responsive approach. It allows for better personalization, supports safer decision-making, and improves the transition back to sport through sustained development of physical and cognitive capacities.
