Table 5 Categories of outcome after shoulder arthroplasty using the constant score

Category	Total CS (/100)	Age and sex adjusted CS (%)
Average shoulder function before arthroplasty	< 30	< 40
Post-op unsatisfactory	< 30	< 40
Post-op fair outcome	30-39	40-49
Post-op good outcome	40-59	50-69
Post-op very good outcome	60-69	70-79
Post-op excellent outcome (i.e., a virtually normal shoulder)	≥ 70	≥ 80
