Is there evidence that the outcomes of primary anatomic and reverse shoulder arthroplasty are getting better?

Purpose

Have the results of shoulder arthroplasty got better over the last two decades? To answer this question, we sought published evidence that the patient-reported outcomes and re-operation rates have improved in reports of more recently performed anatomic (TSA) and reverse (RSA) total shoulder arthroplasties.

Methods

We analyzed the arthroplasty results among studies published from 1990 to 2015, adjusting for the fact that the different publications presented patient groups with different combinations of diagnoses, used various outcome scales, and had different lengths of follow-up.

Results

The adjusted clinical outcomes (p = 0.048), but not the revision rates (p = 0.3), were significantly better for articles reporting more recent TSA procedures. Neither the clinical outcomes (p = 0.9) nor the revision rates (p = 0.4) were significantly better in articles reporting more recent RSA surgeries.

Conclusions

Better evidence from reports with greater detail will be necessary to show that patients are realizing progressively better outcomes from shoulder arthroplasty.
