ACL injuries are among the most common ligament injuries and can have an immediate, significant impact on an individual’s physical function and emotional well-being. While surgical techniques continue to advance, determining when an athlete is truly ready to return to sport remains a complex and high-stakes decision.

A New Standard for ACL Return-to-Sport — The Keiser Approach
Many ACL rehabilitation programs continue to rely heavily on time since surgery to guide progression and return-to-sport decisions. While healing timelines provide useful context, they don’t always reflect an athlete’s true functional readiness or ability to tolerate sport-specific demands.
The Keiser ACL Recovery Guide introduces a criteria-based framework designed to move clinicians beyond timelines alone. Drawing from current evidence and clinical best practices, it outlines three key considerations that support more objective return-to-sport decision-making:
Recovery
Respecting biological healing timelines
Precision
Using objective data, including strength testing, movement symmetry, and force–velocity profiling, to guide decisions
Readiness
Accounting for neuromuscular, neurocognitive, and psychological factors.
By applying these principles across each phase of rehabilitation, clinicians can support more consistent progress, clearer return-to-sport decisions, and a more defensible care process while differentiating their practice through a more data-informed, performance-driven approach.
