These authors conducted a systematic review of 13 studies reporting sequential followup of 984 patients at several time points, up to a minimum of 2 years after total shoulder. Assessment for clinically significant improvements between time intervals was made by using the minimal clinically important difference specific to each patient-reported outcome measure.
Clinically significant improvements in patient-reported outcome scores were noted up to 1 year following TSA, but no further clinical significance was seen from 1 year to 2 years.
For both the subjective and objective outcomes, the majority of improvements occurred in the first 3 months after the procedure.
These authors found similar results for reverse total shoulders as shown in this link.

Comment: It is of interest and importance that the Simple Shoulder Test results of our recent, currently unpublished 11 international center study including 1270 patients receiving anatomic total shoulders with a standard (non-augmented) all polyethylene glenoid component (shown below):
are virtually identical to the Simple Shoulder Test results from this systematic review (shown below):
It also of interest that in this systematic review, the normalized outcomes are essentially independent of the patient reported outcome scale used:
Thus measuring the outcomes of shoulder arthroplasty can be simplified: (1) any of the validated patient reported scoring systems can be used and (2) the one year results are as good as the two year year results (the "standard" requirement for 2 year followup may not be necessary for TSAs). In order for new total shoulder systems to demonstrate that they offer increased value over current approaches, their one year outcomes need to exceed those shown here.
Of course it is recognized that radiographic failure often occurs at 5 to 10 years after shoulder arthroplasty, so much longer periods of followup are required to assess loosening and revision rates.
