After surgery, rehab is what determines whether you come back — and whether you re-tear. Our force-plate-tested, benchmark-driven program has returned hundreds of athletes to sport stronger and more confident than before.
Returning to sport too early — or without symmetry between legs — is one of the biggest drivers of ACL re-injury. We don’t guess. We measure strength, power, and movement symmetry with force plates and dynamometers, and we clear you only when the numbers say you’re ready.
A progressive benchmarking approach — each phase is earned, not timed.
Reduce swelling, restore range of motion, and reawaken the quad early and safely.
Close the strength gap between legs with targeted, measurable loading.
Retrain jumping, landing, and cutting mechanics to absorb force without risk.
Force-plate and field testing confirm symmetry before you’re cleared to compete.
Coming back from an ACL tear is as much mental as physical — especially for young athletes. Our DPTs are trained to manage every stage, from the early post-surgical weeks through high-level return, rebuilding both the knee and the confidence to trust it.
A perfect 5-star rating across nearly 300 reviews — straight from our patients.
Most athletes return to sport between 9 and 12 months after ACL reconstruction, but the timeline is individual. At One Nine we use force-plate and strength testing to clear you based on objective limb symmetry and movement quality — not just the calendar.
Rehab typically begins within days of surgery to control swelling and restore motion early. The sooner you start a structured program, the better your long-term outcome. We coordinate with your surgeon’s protocol.
Force plates objectively measure how much force each leg produces and absorbs. They reveal strength and landing asymmetries you can’t feel — the exact gaps linked to re-injury — so we can clear you to return only when both legs are truly ready.
Yes. Many of our ACL patients had surgery elsewhere and come to One Nine specifically for return-to-sport rehab. We’ll review your surgical protocol and build your program from where you are today.
Some ACL injuries can be managed non-operatively depending on the tear and your goals. We’ll assess your knee and, in coordination with your physician, build the right rehab plan for your situation.
