Thank you to for the invitation and outstanding hospitality! It was a privilege to engage with such an experienced and thoughtful group of surgeons. Even more meaningful was the opportunity to share the stage once again with Manik Dham. Our discussions continue to reflect a shared commitment to advancing the science behind rotator cuff augmentation and pushing innovation forward in a way that truly impacts patient care. Grateful for the continued collaboration and the chance to contribute to these important conversations.

A biceps tendon tear can significantly affect strength, rotation, endurance, and the natural contour of the arm.

When distal biceps tears and is not repaired, patients lose 30% flexion (bending) strength and 50% supination (forearm rotation) strength and endurance.

Time is of the essence after a tear. Since muscle and tendon recoil, there is usually a 3-4 week window where the tendon can be repaired directly back to bone. After that, the muscle and tendon scar and can no longer be attached.

For chronic biceps tendon tears, advanced reconstruction may still be possible. Dr. Mirzayan specializes in rebuilding chronically torn biceps tendons using a donor tendon when direct repair is no longer possible.

It’s not too late if you’ve torn your biceps, it can still be fixed.

Save this if you or someone you know has had a biceps tendon injury.

You usually cannot see a rotator cuff tear directly on an X-ray.

But when a tear becomes massive, chronic, and retracted, the bones can start telling the story.

This X-ray shows end-stage rotator cuff tear arthropathy, classified as Hamada Grade 5.

The key findings include superior migration of the humeral head, narrowing of the glenohumeral joint, glenoid bone loss and deformity, sclerosis, and collapse of the humeral head.

This is one reason X-rays are still important in shoulder evaluation. They show the secondary changes that can happen when the rotator cuff is no longer keeping the shoulder centered.

👉🏼Shoulder X-rays can still be useful, even when the tear itself doesn’t show.

Some moments in surgery are quiet, focused, and incredibly deliberate.

Every step is about protecting the patient, respecting the anatomy, and doing the work with the level of precision it deserves.

OCD of the capitellum is a rare but serious cartilage injury in the elbow, often seen in young overhead athletes, especially pitchers.

For many patients, the question is not just how to restore the damaged elbow surface. It is how to do it without creating a new problem in a healthy joint.

Traditionally, one option has been to take cartilage from the patient’s own knee and transfer it to the elbow. But donor-site morbidity is a real concern, which is why I began using fresh donor cartilage and bone to reconstruct the damaged capitellum instead.

In this study, we reported on 35 patients treated between 2006 and 2022 with fresh osteochondral allograft transplantation for OCD of the capitellum. The majority had unstable lesions, and every patient had already failed nonoperative treatment.

The outcomes were significant: pain improved, elbow function improved, and every overhead athlete returned to sport at the same level or higher for more than two years. Two patients went on to play professional baseball, with top pitching speeds of 94 and 96 MPH.

Seventeen years of treating this condition has reinforced one thing for me: when a young athlete has a damaged elbow, the goal should be to restore that elbow without sacrificing a normal knee when another option exists.

Always grateful when patients feel informed and confident through the process.

Needle arthroscopy (Nanoscope) lets the surgeon see inside the joint in real time, through a minimally invasive approach.

Using a tiny camera inside a needle-like arthroscope, the joint can be viewed directly on a monitor and used to diagnose and treat joint conditions, often with local anesthesia, no traditional incision, and no general anesthesia.

For athletes and active patients, the value is precision with less disruption: a clearer look at cartilage, meniscus, labrum, or other joint structures without immediately jumping to traditional arthroscopic surgery.

Save this for later.
