Preventing Reinjury After ACL Reconstruction
Reinjury is common after an ACL reconstruction. Summit physical therapists Kyle Hall and Jenny Blade explain the risks and share techniques that can help prevent a second injury.
Summit physical therapists Kyle Hall and Jenny Blade have firsthand experience with ACL injuries. Both women underwent ACL surgery as student athletes, and both suffered second ACL injuries following their surgeries. Now they work in Summit’s ASCEND program, which is designed to reduce the risk of recurrent ACL injury.
“Reinjury following ACL surgery is a real risk,” says Kyle. “And fear of reinjury is another factor that can increase an athlete’s risks. After one knee has been hurt, we have a tendency to try to protect our surgical knee—and that puts more stress on our other knee, increasing the likelihood of a second ACL injury.”
Kyle and Jenny review some of the factors that lead to reinjury once athletes return to sport following ACL reconstruction.
- Muscle weakness
- Impaired balance
- Fear of reinjury
- Returning to play too early
“It takes time to recover after an ACL reconstruction,” says Kyle. “Most reinjuries occur between three and nine months after an ACL surgery.”
“Research also tells us that fear of reinjury is the No. 1 reason that people do not feel ready to re-enter their sport,” Jenny points out. “They might test out with plenty of strength, but still feel nervous about pivoting on their surgical leg, even though they can do it with good form.”
Summit’s ASCEND program was designed for injured athletes who want to get safely back to competition. The program uses rehabilitation techniques shown to reduce reinjury risks.
- Respect the healing process. Because full graft healing can take 8 to 12 months or longer, patients aren’t eligible for the ASCEND program until they’ve completed their functional rehabilitation following surgery. “If your surgeon used a donor allograft to repair your knee, expect healing to take even more time,” Kyle explains. “When you return to sport too soon, you aren’t strong enough—and your surgical repair may not be strong enough—to handle the physical stress of competition. Studies have shown that deficits can remain up to two years after an injury or surgery.”
- Reclaim neuromuscular control. “Graft strength is important,” says Kyle, “but graft strength alone isn’t enough to prevent reinjury. Studies tell us that rebuilding neuromuscular control is an accessible and effective way to reduce the chance of a second ACL injury. The ASCEND program addresses four neuromuscular imbalances, because we know that this approach reduces injury risks by 30 to 80 percent.”
- Make warm-ups a habit. Active warm-ups have been shown to reduce injury by 88 percent.
“We help our patients safely regain strength through techniques supported by research,” says Jenny. “That’s what ASCEND is all about. When our athletes step onto the field, we want them to feel confident, focused, and ready to play.”

There are multiple treatment options for ACL injuries, and new research tells us that age is an important factor in selecting the treatment that will deliver the best outcome. Dr. Skendzel explains how age influences the surgical approach he recommends for an ACL reconstruction.
Everyone is susceptible to bone and joint problems, but studies suggest that genetics influence your degree of risk for certain orthopedic conditions, and may also influence the success of your recovery.
We know that physical therapy after joint surgery is a critical part of the recovery process, but can therapy before surgery also improve our recovery?
