A perfect final case to close out the rotation for our visiting researchers from Austria 🇦🇹. Now that’s a textbook Type I tear! Huge thanks to and for their dedication and tireless contributions to the ongoing research. Your attention to detail has not gone unnoticed and we’re excited to see the results of your efforts in a few upcoming publications. The future is bright for these two. Wishing you both a safe journey home. Gute Reise! ✈️

Comeback Alert! We’re celebrating the incredible recovery of our rockstar 22-year-old patient who recently crushed some major milestones:
🏃‍♀️ Ran a half marathon at just 11 months post-op
🥾 Summited Mount Washington on the 1-year anniversary of her ACL repair

Her journey started with a mid-substance ACL tear from a skiing injury. Timing wasn’t right for surgery at first, and during that delay, her ACL began to heal. When it was finally time, I was able to dissect the healing ligament off the PCL and reattach it to its native footprint, no graft needed.

Today, her knees are completely symmetric in strength and stability and she’s back to living life at full speed. Total comeback. Total inspiration. 💪

Another great follow-up! Two years out from an ACL Avulsion Fracture, also known as a McKeever Fracture, Repair and doing incredibly well.

📸 Swipe through the case:

Picture 1: Sagittal MRI showing the displaced tibial spine avulsion, where the ACL was pulled off its bony attachment. Picture 2: Intraoperative arthroscopic view of the fracture site before fixation. Picture 3: Post-fixation view, showing the ACL re-tensioned and the avulsed fragment reduced and stabilized with sutures. Picture 4: The best shot of the series, celebrating her successful recovery! Love it!

What a case! This patient is a 42-year-old man, 3 months out from a ski injury with an isolated proximal ACL tear. Seen here just one week after undergoing primary ACL repair and already doing remarkably well. It’s not every day you hear a patient describe ACL surgery recovery as “super easy.” We will continue to follow him closely over the course of his recovery!

Looking forward to the AOSSM Annual Meeting 2025! Join me at Booth 628 on Thursday at 10:15 AM for ACL Repair Hour, where I’ll be sharing real-world cases and answering your questions live. I’ll be discussing how I have incorporated OSSIOfiber® biointegrative suture anchors into my Preservation First® approach. Hope to see you there!

One year out from an ACL reconstruction using autograft quadriceps tendon with lateral extra-articular tenodesis. Heading into the summer season back out on the pitch. We wish her luck on her upcoming season!

1.5 years out from an ACL Avulsion Fracture (also known as a McKeever fracture) Repair and doing great! Full range of motion and back to her activities. These injuries can be tricky—especially when it comes to fully reducing the fracture. Here’s my approach: In image 2️⃣, you can see the ACL secured with sutures for better control, as well as the gap where the avulsion occurred (arrow). In images 3️⃣ and 4️⃣, the fracture is reduced and everything is back in place. Healed beautifully.

Back for her 2-year follow-up after Right knee ACL Primary Repair and doing great! Skiing, running, and she just completed her first half marathon. She previously had an ACL reconstruction on her Left knee 8 years ago and was determined to explore her options. That’s how she found us. Her repaired knee not only feels better than her reconstructed one, but on objective testing with the , it’s actually 1 mm more stable. Always rewarding to see patients thriving.
