    This RCT tested ultrasound-guided PRP injection plus rehabilitation versus rehabilitation alone in 48 athletes with partial (grade 1-2) ACL injuries. Unlike ACL reconstruction augmentation studies, this examined PRP as a non-surgical treatment for partial tears. The PRP group showed significantly better IKDC and Lysholm scores and lower VAS pain at 4, 8, and 12 months. This represents a distinct clinical scenario from complete ACL tears requiring reconstruction.

    Clinical Relevance

    Opens a potential role for PRP in non-surgical management of partial ACL tears, a situation where the intact ligament fibers may serve as a scaffold for PRP-enhanced healing. This is a different clinical question from PRP augmentation during surgical reconstruction.

    Key Takeaways

    • PRP + rehab significantly superior to rehab alone at 4, 8, and 12 months
    • IKDC and Lysholm scores both significantly improved
    • Tested in partial ACL tears (grade 1-2), not complete ruptures
    • Ultrasound-guided injection directly to the ligament
    • 48 athletes (small but focused population)
    • PRP may support ligament healing in partial tears where some intact fibers remain

    Key Findings

    48 athletes. PRP + rehab significantly improved IKDC and Lysholm vs rehab alone at 4, 8, 12 months. PRP may have a role in PARTIAL ACL tears.
