Ten weeks after an ACL primary repair with BEAR augmentation and already back in the gym. Weighted Bulgarian split squats with great control and confidence. Steady progress and solid work at this stage. 💪

Broke out the holiday jacket to celebrate our patient who is one year out from ACL reconstruction using autograft quadriceps tendon with remnant tensioning. He is officially back on the track. At his first meet back he took second place in the 300 m. Not a bad Christmas present at all! Wishing everyone a joyful holiday season filled with health, strength, and wins like this. Merry Christmas and happy holidays to all 🎄✨

18 months after an ACL reconstruction using autograft quadriceps tendon with remnant tensioning and absolutely thriving. Backflips. Power. Confidence. All of it on full display as she crushes it with the cheer team at Seton Hall. So proud of this comeback and even more excited to watch what comes next.

Had a fantastic OR day last Friday. Five cases. Seven repairs.
Rotator cuff. Pec tendon. Three ACLs. Two meniscal repairs. We capped off an incredible day by celebrating our research fellow, . So grateful for everything he brought to the team and excited to see what’s next for him.

Who says 44-year-olds aren’t athletes?
Two years out from ACL primary repair and he’s proving exactly the opposite. He went undefeated in the 18+ USTA 4.5 Vermont season, starting just seven months after surgery. Yes, that means he’s competing in the 18–40 bracket… and outperforming everyone.

He even tossed in a couple of Turkey Trots last month with zero issues, just for fun.

Grateful he traveled three states to have his ACL repaired and even more grateful to see him thriving.

From the operating room to long-term follow-up. This is why Preservation First® matters. Swipe to see something pretty special: a skier’s ACL, repaired in the OR, and an MRI eight years later showing it still intact, still strong, and still doing its job. Preservation First® isn’t a theory. It’s measurable.

There is a lot of stress being a surgeon. Only in the past five years since the pandemic have people been talking about it. It’s about time! We need to take care of ourselves mentally, or we won’t be able to help others.
I have always played guitar. Acoustic, old stuff, sang a bit. I found it a good release. Didn’t have the confidence to play much in public.
Then one day, I was taking care of a patient who got hit by a car. Acute ACL/MCL Repair. Quick recovery. Perfect outcome. He was a lead guitarist for multiple bands. I asked him to show me some riffs on electric. We jammed for 3 hours. What fun! He told me, “Doc, it’s much more fun to play in a band,” so I asked him to be in my band. Why not? Two weeks later, another patient returned to thank me for his successful rotator cuff repair. He told me that he had been a drummer on Broadway for 35 years! So, I asked him if he wanted to be in my band. One of my singers, broke her collarbone. So, I asked her to be in my band.
And so it went. My band’s called Dr. D & The Repaired Men.
Seriously. That’s the actual lineup. Patients/players have come and gone, but the common thread is that they (or their wives recently) have all been repaired. Every one of them had something fixed or replaced by me. Every one worked their way back to the life they loved, including playing or singing.
Over the years, the band has gotten bigger and better. We play around the city, and my friends help me to raise money to support my research so I can better help others. And the research helps other docs to better help others. My first bandmate was right. It is much more fun playing with others in a band.
What surprised me most wasn’t the music. It was the reminder that the people you help to heal often become part of your own story too. Some surgeons end up with trophies or plaques. I ended up having fun with friends who make music with me.

Honored to meet and share my experience with ACL Primary Repair with Dr. Florian Imhoff from University Hospital Basel, Dr. Robin Martin from University Hospital Lausanne, and Dr. Christian Egloff from the Schulthess Klinik in Zurich. We had a fantastic day in the OR with four ACL cases: two Primary Repairs, one repair with BEAR Augmentation, and one straight reconstruction. And of course, I had to share a bit of New York City nightlife — a pizza and pub crawl through Greenwich Village that ended at Terra Blues with some great live music.

Enjoyed hosting from Münster, Germany a few weeks ago for some meaningful conversations on ACL and multiligament preservation. Dr. Schneider has contributed significantly to this growing field has published, alongside his mentor Dr Georg Ahlbäumer, of the Klinik Gut in St Moritz, Switzerland, on their impressive experience with ACL primary repair.

It was a pleasure to spend time sharing insights, research, and future directions. Congratulations to Dr. Schneider not only on his clinical achievements, but also on completing the New York City Marathon. And of course, no international visit is complete without a jersey exchange.

Two years after an ACL Primary Repair and already achieving new heights. Winning her Tennis Club Championship is an incredible reminder of what dedication, patience, and a strong recovery plan can make possible. This journey shows that healing is not just about getting back to normal, it is about coming back stronger. Huge congratulations on an inspiring achievement.

Check this out! At just 8 weeks after an ACL Primary Repair, our patient here was back to running a mile. Fast forward to 10 weeks, and he’s crushing box jumps without a single issue. Watching the body respond and rebuild like this never gets old.

Eight months out from ACL Primary Repair with the Bear Implant and already back to Beast Mode. 🇨🇦🏉🛷
From Canadian Junior rugby to bobsled… this athlete doesn’t slow down, she accelerates. Proud to be part of her comeback story.
