The “cam” deformity of the femoral neck is the leading cause of hip impingement. This is essentially an area of extra bone that creates impaction and friction between the femoral head and acetabulum. What then gets caught in the middle of this is the labrum, which sits at the edge of the acetabulum. This bony impingement is what creates the soft tissue injury of a labral tear in many cases. 

During hip arthroscopy for hip impingement and labral tear, the Cam resection is a vitally important part of the procedure to eliminate the bony impingement 

Revision knee arthroplasty provides an excellent opportunity to showcase the capabilities of modern robotic technology. These procedures often involve significant challenges, including managing bone loss, selecting appropriate implants, and achieving optimal motion and stability of the joint. Robotic assistance can significantly enhance the efficiency, accuracy, and safety of these complex surgeries.

In this video, I demonstrate a revision case in which a medial unicompartmental knee arthroplasty (partial knee replacement) is converted to a total knee arthroplasty (full knee replacement). As is often the case with partial knee replacements, the remaining compartments of the knee can continue to degenerate over time. This patient presented with worsening pain due to progressive arthritis in the lateral and patellofemoral compartments, indicating the conversion to a full knee replacement.

Robotic technology plays a critical role in these revision procedures by guiding implant selection and placement, with or without the use of augments. It ensures precise alignment and positioning of components, contributing to a well-balanced and stable knee.

Testimonial Tuesday!

Heterotopic Ossification excision 😳
•
This patient had been dealing with pain and loss of range of motion despite extensive PT and non surgical treatments. Initial work up with X-rays demonstrated this very large calcification anterior to his hip. MRI revealed this was within his re**us femoris.
•
After seeking a few opinions this patient reached out virtually and after discussion decided to travel from out of state to have this removed. This was able to be completely removed while preserving his re**us as well as concomitantly decompressing his subspine.
•
This calcification, otherwise known as heterotopic ossification, likely formed from a strain of his re**us or avulsion fracture of the anterior iliac spine (he did not recall a specific injury but played a high level of football into his mid 20s). The HO at the time of surgery was very mature and well defined. He was placed on NSAIDs postoperatively to lower the risk of recurrent heterotopic ossification formation.
