🫷 Elbow pain, locking, or catching? It could be loose bodies in the joint.

Sometimes small pieces of bone or cartilage break off inside the elbow and float around in the joint — which can cause pain, stiffness, or a “catching” sensation when you bend or straighten your arm. These are called loose bodies, and they can interfere with smooth movement and daily activities.

If conservative treatment isn’t enough, surgical removal can often relieve symptoms and improve motion. Dr. Jonathan Glashow offers diagnosis and advanced minimally invasive treatment for loose bodies in the elbow right here in NYC, helping patients get back to the activities they love.

Nikos’s Journey Back to Soccer

When multiple ACL surgeries and ongoing injuries create a perfect storm of cartilage damage and joint narrowing, sometimes you need to think beyond traditional approaches.

Nikos came to us with lateral compartment damage - not just torn cartilage, but loss of joint space from previous surgeries and injuries. This required a two-part solution: an osteochondral allograft to fill the cartilage “pothole” and a corrective osteotomy to realign the bone and take pressure off the repair.

The result? Nikos went from severe pain to walking without crutches, swimming, and moving better each day. Much of his success so far has also been due to his determination and consistently during the rehab process. Great work so far, Nikos!

Every knee tells a story - this one had multiple chapters, but we’re working on writing a better ending.

A meniscus tear is one of the most common knee injuries in sports medicine. It can happen during a quick pivot on the basketball court, a sudden twist while skiing, or even a deep squat at the gym. The meniscus is a C-shaped piece of cartilage that cushions the knee joint and helps distribute weight. When it tears, the knee often loses some of the smooth, stable movement you normally expect.

Common causes, symptoms and repair:

If you or someone you know is dealing with a torn ACL, there’s an exciting new option now available with Dr. Glashow — the BEAR® (Bridge Enhanced ACL Restoration) implant! 🙌

Instead of traditional ACL reconstruction that uses tendon grafts, the BEAR implant helps the body heal its own torn ligament by bridging the gap in the ACL with a biologic implant and using your own blood to kick-start the healing process. This innovative, FDA-approved approach preserves your natural ACL anatomy and may lead to faster recovery and less surgical trauma compared with traditional methods.

✨ Why this matters:
• Uses your own blood and natural healing
• Quicker return of muscle strength & higher patient satisfaction.
• The implant is absorbed by your body in 8 weeks as you heal

Dr. Glashow is a leading orthopedic surgeon with decades of experience helping athletes and everyday people get back in the game. If you’ve suffered an ACL tear, this could be a less invasive, next-generation treatment option worth exploring! 💪

Distal bicep tears are one of the most time sensitive injuries we see. Early evaluation matters and this patient came in within days, which has made all the difference so far 👍

✨ Tuesday Tip ✨
Revision ACL surgery is a second reconstruction performed when a prior ACL repair hasn’t fully restored stability or has failed. It’s more complex than the first surgery and requires careful planning and rehab, but many patients can still return to activity with the right approach.

Consulting with an experienced knee specialist early can help you understand your options and set realistic recovery expectations!
