Juan Gutiérrez: Complete Achilles Tendon Tear Heals After Frassati Novena

In 2017, Juan Gutiérrez, a Mexican seminarian studying at the Archdiocese of Los Angeles, tore his Achilles tendon playing basketball. An MRI confirmed a complete rupture. His orthopedic surgeon recommended surgery. Gutiérrez, aware of Pier Giorgio Frassati's reputation, began a novena to him.

Several days into the novena, Gutiérrez was praying in an empty chapel and felt an unusual sensation of heat around his injured foot. When he returned to the orthopedic surgeon for the pre-surgical appointment, the surgeon examined him and then reviewed the imaging: "You must have someone in heaven who likes you." The tendon appeared healed. Gutiérrez resumed sports without restriction.

The Archdiocese of Los Angeles opened a diocesan inquiry. The case was forwarded to Rome, where the Dicastery for the Causes of Saints medical board reviewed the MRI comparisons and clinical record. Pope Francis formally recognized the miracle on November 25, 2024. Frassati was canonized on September 7, 2025, alongside Carlo Acutis, by Pope Leo XIV.

The scientific crux: a complete Achilles tendon rupture in a healthy young athlete does not self-repair within a novena — roughly nine days. The tendon heals via scar tissue over months, never regenerating structurally within days. If the pre-prayer MRI accurately reflects a complete rupture, the post-prayer MRI showing a normal tendon requires explanation beyond natural history. The qualification is that MRI reading accuracy for complete versus partial tears is not 100%, and no independent radiology review has been published.
