Shoulder osteoarthritis across the lifespan
Osteoarthritis (OA) in the shoulder is a common problem in our patients. Thereby, in patients older than 60 years, a prevalence of up to 20% is mentioned [1,2]. However, due to the unique anatomy of the shoulder as a non-weight-bearing joint, surgical options such as arthroplasty have been traditionally used to a much lower extent, for example, for the hip and knee joints [3,4]. This is also based on the fact that the symptomatic glenohumeral osteoarthritis (GHOA) is not as common as osteoarthritis of the weight-bearing joints such as the hip and knee [1].
