Science Reconfirms Benefits of Shoulder Inlay Glenoid Arthroplasty For Active Patients

May 10, 2017

OVO with Inlay Glenoid Arthroplasty ImplantFranklin, MA., May 10, 2017 – Arthrosurface, Inc., the Global Leader in Inlay Glenoid Arthroplasty announced new evidence showing dramatic differences between the company’s inlay glenoid technology and the standard of care in total shoulder replacement.

According to a comparative study in the Journal of Shoulder and Elbow Surgery, the inlay glenoid (socket) design was far superior to the onlay alternative with respect to the biomechanical stability. “Increased stress on the implant edge resulted in loosening of all onlays through a roc
king horse phenomenon, whereas none of the inlays became loose during testing” said the lead author Jeffrey Gagliano, MD from the Boulder Bone and Joint in Colorado. Richard Hawkins, MD, from the Steadman Hawkins Clinic of the Carolinas, Greenville, SC and senior author of the study concluded, “given the results of the study, future research and development should be directed toward inlay glenoid prosthetic design, matching native anatomy and size variation.”

The American Academy of Orthopaedic Surgeons estimates about 53,000 people in the United States have shoulder replacement surgery each year. The benefits of replacing both sides of the joint with a total shoulder arthroplasty have been well established, however, glenoid loosening remains the Achilles Heel of the procedure.

“According to the literature, 2-10% of patients treated with a standard total shoulder replacement will require a revision procedure within the first decade following surgery due to onlay glenoid component loosening. Inlay arthroplasty may provide a solution to lower the revision burden on patients and the healthcare system,” said Matthias Schurhoff, VP of Clinical Operations and Scientific Affairs at Arthrosurface.

The company’s OVO Primary Stemless Shoulder System with inlay glenoid replacement was launched in the US in 2009 and has experienced excellent surgeon adoption. The inherent advantages are particularly well suited for younger and active patients requiring shoulder joint replacement surgery.

    I had an arthrosurface arthropladty almost a year ago and opted for nothing to be done to my Gleniod. I have been very happy and resumed all prior sports.
    What are the thoughts why anything needs to be done to the Glenoid?

  2. Russell Zito says:

    I’ve had a hemicap procedure 1yr 3mo ago and my shoulder is getting pain again more and more with daily activities. What should I do next to get this fixed before it gets real bad .

    • Stephen Gertson says:

      I am in the same boat as Russell Zito. I am three years post hemicap procedure. I am experiencing more frequent and prolonged incidents of shoulder pain. My labrum was almost non existent at the time of hemicap procedure. We opted not to implant the glenoid capsule due to my age and high activity level at the time of hemicap surgery. I am wondering if going back in and putting the glenoid capsule would help.

        Hi Stephen, only a licensed doctor can tell you for sure if the glenoid implant is the right solution for you. We recommend going back to see your implanting surgeon to discuss all options.

    Sorry to hear. I am 18 months out now without a glenoid inlay and continue to enjoy an active lifestyle relatively free of any pain. Some stiffness of the joint after long swims and heavy lifting but otherwise less discomfort than my other shoulder.

    Are there any doctors that perform is procedure in Canada? Particularly Vancouver Canada

    Are there any studies showing if the glenoid inlay helps patients with pre-exisiting sub-chondral cysts in the glenoid. I had a ream and run surgery in 2016, however, the reaming hasn’t helped due to the sub-chondral cysts. My next step is to have some sort of glenoid component installed. Just curious if the inlay would be an option. I am very active and do lift weights, however, the shoulder pain has restricted what I can do.
