What People Are Saying About Catalyst

  • Timothy G.
    I’ve used the Catalyst system for the last year with tremendous results in patients with end-stage shoulder arthritis. The system allows anatomic reconstruction of the glenohumeral joint with a minimally invasive approach, and simple, easy to use, instrumentation. My patients are recovering quicker, with less pain, and have very good short-term results compared to patients that have a more standard, stemmed design.

    I have been using the Catalyst shoulder prosthesis for all my anatomic total shoulder arthroplasty cases since 2017. I have used most of the other systems currently available and have found that the Catalyst is simply the most anatomic system on the market. The fit is a precise anatomic reconstruction in every single case. The surgical technique and instrumentation are pared down and streamlined, and the cases go much quicker. The system is easy to learn - the X-rays from my first Catalyst case looked perfect! I have been doing less soft tissue releases with the Catalyst, which means less postoperative pain and a faster recovery for my patients.

    All I can say is WOW. In March of 2016, I had my right shoulder replaced. Then in January 2017, I had total shoulder replacement on the left side [with] the new Catalyst Total Shoulder System. I thought my right shoulder replacement surgery was fine because it was all I knew at the time. My result with Catalyst is so much better. After the right shoulder surgery, I slept in a chair for 3 weeks. This time, on the very first night after surgery, I slept in my bed the whole night. I felt really good and was virtually pain-free. Three months later, I feel like I haven’t even had surgery. I am able to put dishes away on the top shelf and hang clothes without difficulty or pain. I definitely could not do that at this point after my right shoulder surgery.
