The cost of shoulder arthroplasty is usually divided by its benefit to the patient. The preoperative to postoperative changes in comfort and function of the patient are commonly referred to as “benefit”. The costs of preoperative care, the implant, hospital care, and any complications could be considered “costs”.
Longitudinal Assessment of Shoulder Arthroplasty Use, Clinical Outcomes, And Value: A Comparative Assessment Of Changes in Improvement over 15 Years With a Single Shoulder Prosthesis. The authors conducted a longitudinal analysis of the extensive experience they had with anatomic (aTSA), and reverse total shoulder surgery (rTSA). Their goal was to quantify changes in clinical outcomes, cost, value, and other factors associated with the adoption and use of new shoulder arthroplasty technology.
2007 saw 19% prosthetics attributed to rTSA compared to 57% aTSA.
In 2021, 76% of prostheses were accounted for by rTSA, compared with 14% aTSA
