The collective gasp heard across Kansas City on December 14th was more than just a reaction to a lost game; it was the sound of a city holding its breath for its hero. When Patrick Mahomes left the field with what has now been confirmed as a ruptured ACL, the immediate reaction was one of devastation. However, according to leading sports rehabilitation expert Aaron Borgman, the narrative of “season over” for 2025 might be premature. In a recent deep-dive discussion, Borgman, a veteran of 12 years on NFL sidelines and owner of Borgman Rehab Solutions, provided a masterclass on why modern medicine and elite-level care offer a much brighter outlook than fans might expect.

The Mechanics of the Injury

To understand the path forward, we must first understand the damage. The ACL, or anterior cruciate ligament, is the primary stabilizer of the knee, controlling the forward and backward movement of the femur on the tibia. Borgman explains that the mechanism of Mahomes’ injury—a combination of a rolled ankle, a hyperextended knee, and a “pivot shift” rotary motion—is the textbook recipe for an ACL tear. While the word “rupture” sounds final, Borgman notes that in the world of professional sports, the ACL is actually one of the most straightforward ligaments to address. Unlike multi-ligament tears that require staged surgeries and years of recovery, a “clean” ACL tear allows for a more predictable and streamlined rehabilitation process.

The Revolution in Recovery

One of the most encouraging takeaways from Borgman’s analysis is how far the profession has come. “We’ve gotten really, really good at ACL recovery,” Borgman says, noting that what was once a “death sentence” for an athlete’s career 20 or 30 years ago is now a common hurdle. The secret lies not just in the surgery, but in the evolution of rehabilitation.

One of the game-changing tools mentioned is Blood Flow Restriction (BFR) therapy. Originally pioneered by the U.S. military for amputees, BFR allows trainers to advance strengthening exercises much earlier than previously possible by magnifying the effects of low-intensity workouts. Combined with force plate testing and digital monitoring, the quality of the time spent in rehab has increased exponentially. While biological healing cannot be “rushed”—Borgman points out that graphs can take up to two years to be 100% biologically integrated—athletes are now routinely returning to peak performance long before that mark by hitting specific functional benchmarks.

The September Question: Can He Make It?

The question on every fan’s mind is simple: Will Patrick Mahomes be under center in September? Borgman’s “napkin math” suggests it is a very real possibility. While the standard recovery window for an NFL player is typically 9 to 10 months, the elite level of care Mahomes receives could shorten that.

“I don’t see missing the entire season as a likely option,” Borgman states confidently. He outlines three scenarios: starting the season on time, missing just a few games, or missing the whole year. According to his expertise, the first two options are “vastly more likely.” For a player with Mahomes’ resources, surgery happens within days, not weeks. The rapid transition from injury to the operating table to the rehab pool is a luxury that gives professional athletes a significant head start.

Benchmarks to Watch

For fans looking for signs of progress, Borgman suggests keeping an eye out for specific “checkpoints.” The three-month mark is usually when straight-line running begins. While fans shouldn’t over-analyze social media clips of Mahomes throwing a football during OTAs—as throwing doesn’t require the same “pivot” stability as game-speed cutting—hearing reports of “cutting and lateral movement” will be the true indicator that the MVP is nearing a return.

Borgman also highlights the “proprioception” factor—the body’s ability to sense its position in space. This “feel for the game” is often the final hurdle. An athlete can be physically strong and fast in a gym, but regaining the instinctual movement required in a live pocket is what defines the final stage of recovery.

A Message of Resilience

While the road ahead is undoubtedly long, the message for the Chiefs Kingdom is one of resilience. The technology and expertise available today are designed for exactly this situation. “The things that were a death sentence 20 years ago aren’t that anymore,” Borgman concludes. Patrick Mahomes has built a career on defying the impossible on the field; now, he prepares to do the same in the training room. With a recovery window that aligns closely with the start of the 2025 season, the narrative isn’t about the end of an era, but the beginning of an incredible comeback story.
