Great time at the AAOS Annual Meeting in New Orleans and the NFL Combine. Always a pleasure connecting with former fellows and the OG himself, Dr. Rick Ferkel.

One of the best parts of these meetings is teaching the next generation while continuing to push the field forward in small-scope technology and biologics.

None of this would be possible without an incredible team at NYU Langone Orthopedics, our outstanding fellows, and the continued collaboration with industry partners. Grateful to be part of such a strong community advancing foot & ankle care.

Concentrated bone marrow aspirate (CBMA) is an advanced orthobiologic that contains growth factors, mesenchymal stem cells, and potent anti-inflammatory mediators such as IRAP.
It is used to augment tendon repair, fracture healing, and cartilage procedures by enhancing the biologic environment at the treatment site.
Published evidence shows that CBMA works not by by activating local signaling pathways and modulating inflammation, leading to faster and better healing.
As always, appropriate indication and technique are key.

Sunday was about the game, but it was also about perseverance, resilience, and the people who make the journey worth it. Forever grateful for quality time with my son and nephew, and the athletes who remind us that with hard work, faith and family, anything is possible.

Platelet-rich plasma (PRP) is a biologic treatment derived from a patient’s own blood and designed to support healing by reducing inflammation and promoting tissue repair.

When appropriately prepared and correctly applied, PRP can play a valuable role in treating tendon pathology, cartilage injury, bone healing challenges, and select muscle injuries.

Not all PRP is the same which is why patient selection, preparation method, and evidence-based use matter.

A glimpse into this week’s cases in the operating room 💪🏻
From AOT to fracture fixation and ligament repair, each procedure is tailored to the patient and pathology. Always focused on precision and biologic augmentation. 💥

A well-executed Scarf Osteotomy provides a powerful and stable correction for hallux valgus (or bunion). Our rotational modification improves cortical engagement, preserves vascularity and is supported by the largest US series and multiple peer-reviewed studies.

Educational surgical footage ⚠️

Take a look at the new surgical technique we’re using to treat arthritis of the first toe (hallux rigidus). This approach uses an osteoperiosteal graft to help restore anatomy and support better outcomes.

Also we just published a new article on this technique! Screenshot at the end of the video and link in bio to read more. 💪🏻

I’m truly impressed after our visit to the ARTHREX campus in Naples, FL. Outstanding infrastructure, an exceptional team, and a culture driven by research and innovation.
Let’s just say some exciting projects are quietly taking shape… 👀
And because the best work also happens outside the lab, we wrapped up the weekend with great food, great conversations, and even better team bonding!!

Excellence on College Football’s biggest stage 🏆
I was honored to witness the Heisman Trophy ceremony with Doug Flutie and an incredible group of finalists: Diego Pavia, Jeremiyah Love, and Julian Saying.
And of course a special congratulations to Fernando Mendoza, our 2025 Heisman Trophy winner! 👊🏻

Grateful for another year and for the incredible team who surprised me with a birthday celebration this Wednesday 🥳
Ended the post with a throwback picture featuring my sons Jack and James, always part of my celebrations, near or far. 💙
