From fearing permanent mobility issues to making her high school varsity volleyball team, our daughter's 14-month recovery was made possible by Dr. John Kahl at ACLRX. His unmatched expertise, structured progression, and selfless dedication turned our family’s greatest fear into an incredible victory.
When our daughter, Karina, tore her ACL in April 2025 and underwent surgery that May, we expected a challenging road ahead, but we never anticipated how frightening it would become. By October, five months after surgery, Karina was significantly behind in her rehabilitation. She still lacked full leg extension, her progress had completely stalled, and our primary concern had shifted from ever seeing her play volleyball again to fearing permanent mobility issues.
Finding Dr. John Kahl at ACLRX completely turned her trajectory around. From October 2025 through July 2026, spanning 10 continuous months of dedicated work, Dr. John stood by our side. From our very first consultation, he listened to our fears with genuine empathy and immediately established a structured, actionable plan. He systematically guided Karina through every critical milestone, painstakingly building her back up step by step: restoring her basic mobility and full leg extension, progressing to jogging, building up to running a mile, incorporating high-impact plyometrics, and ultimately mastering dynamic sprinting and cutting on the court. His communication, responsiveness, and clinical guidance were superior at every single stage.
What truly sets Dr. John apart, however, is his remarkable integrity and commitment to his athletes. His focus was never on the billing cycle; it was entirely on getting our daughter healthy.
Looking back on this intense 14-month recovery, the results speak for themselves. In August 2026, Karina officially stepped back onto the court and made her high school varsity volleyball team.
To see her competing at the varsity level after a time when we feared she might live with a lifelong physical disability is an absolute blessing. That achievement would simply not have been possible without the partnership, structure, and selfless dedication of Dr. John Kahl. We are endlessly grateful for what he did for Karina and recommend ACLRX without reservation to any family navigating an ACL journey.
Sincerely,
The Peboontom family
