These authors collected data on 1,183 patients who underwent either anatomic total shoulder arthroplasty (n = 505) or reverse total shoulder arthroplasty (n = 678) and had a minimum follow-up of 2 years.
They found that most improvement occurred by 6months, with some additional improvement up to 2 years for both anatomic total shoulder arthroplasty and reverse total shoulder arthroplasty.
Here are there results for the Simple Shoulder Test, showing the preoperative scores and the results out to two years (the time at which all shoulders were represented).
Comment: These data obtained using the Simple Shoulder Test are useful in informing shared surgeon-patient decision making by demonstrating both (a) the typical self-assessed shoulder comfort and function before surgery and (b) the rate of improvement in this measure after surgery.
In viewing these data, it is important to recognize that these results are from a high volume center with established guidelines for patient selection and standardized surgical technique. These parameters may or may not be the same for other practice venues.
