You're Not Too Old for ACL Surgery

At least once a week, I see a patient in their 50s or 60s who tore their ACL skiing, playing pickleball, or just stepping off a curb wrong. They've already been told by someone — a friend, the internet, sometimes even another doctor — that they're "too old" for ACL reconstruction.

That advice is outdated, and new research confirms what I've been seeing in my own practice for years.

What the research says

A study out of NYU Langone Health, presented at the American Academy of Orthopaedic Surgeons annual meeting earlier this year, looked at 155 patients over age 50 who underwent ACL reconstruction. These weren't cherry-picked cases — 82% also had a meniscus tear that needed to be addressed at the same time.¹ The results were striking:

That 7.1% graft failure rate is comparable to what we see in younger patients. And nearly two-thirds of patients got back to doing exactly what they were doing before their injury. The takeaway: physiological age — how healthy and active you are — matters far more than the number on your driver's license.

What I see in my own practice

I perform approximately 85 ACL reconstructions per year, and a growing number of those patients are over 50. The conversation I have with them is the same one I have with a 25-year-old: What do you want to get back to? If the answer is skiing, tennis, hiking on uneven terrain, or chasing grandkids around the yard, a floppy knee without an ACL is going to limit you. Activity level drives the decision, not age.

The surgery itself is no different. I use the same techniques and grafts. Recovery follows the same protocol — though I'll be honest, patients in their 50s sometimes take a little longer to hit their milestones compared to a college athlete. That's normal and expected. What doesn't change is the end result: a stable knee that lets you do what you love.

When it makes sense — and when it doesn't

ACL reconstruction isn't the right call for everyone. If your knee is stable enough for daily life and you're content with walking, golf, and swimming, you may do just fine with physical therapy alone. But if your knee buckles when you pivot or you're giving up activities that keep you healthy and happy, surgery is worth a serious conversation.

The one caveat: significant arthritis can change the equation. If you've got bone-on-bone wear in the same compartment as the torn ACL, we need to talk about that. In general, we do not do ACL reconstruction if the knee is arthritic, because the knee needs treatment of the arthritis more than stability from the ACL. Sometimes the better path is a partial or total knee replacement rather than a ligament reconstruction. That's a case-by-case call, and it's exactly the kind of nuance that makes an in-person evaluation important.

If you've been told you're too old for ACL surgery and that doesn't sit right with you, trust that instinct. The data backs it up. I'd love to talk it through with you in clinic.
