Editorial Commentary: There Is No Standard for or Standardization of Postoperative Rehabilitation Protocols After...

The anterior cruciate ligament (ACL) is the most studied ligament in the knee and one of the most studied topics in orthopaedics, with little consensus on best options for surgical technique or graft choice. While there is little question that physical rehabilitation is one of the most important variables in the episode of care before and after ACL reconstruction (ACLR), recent research surveying orthopaedic surgeons demonstrates no consensus of how to rehab ACLR patients and how to get them to return to sport safely and quickly. Seventy-two percent of surgeons prescribe "pre-hab" prior to ACLR, and 83% of surgeons use postoperative bracing, with most (55%) bracing for 3 to 6 weeks postoperatively. Patient-reported outcome measures (35%) and assessments of psychological readiness (23%) are not commonly used to progress patients through the stages of rehab. When asked what they believe is the single most important factor in unrestricted return to sport, 52% of surgeons stated functional testing scores were most important, while 38% stated time since surgery, and 5% stated muscle strength. As for average time to return to full activity, 50% of surgeons waited until 9+ months for full return, and 42% allowed return within 6 to 8 months. Reductions in practice variability have been shown in orthopaedic surgery and other fields to reduce costs of care delivery and improve patient outcomes, and with so much variability in ACLR rehabilitation protocols, the orthopaedic community would be wise to strive for more consensus focused on evidence-based recommendations for rehabilitation and to fill in knowledge gaps with focused, high-quality research where needed.
