Background:
Revision shoulder arthroplasty (SA) is a surgical procedure performed to address complications or failures of primary total SA. However, limited evidence exists regarding the functional outcomes and longevity of implants following revision.
Methods:
A retrospective analysis was conducted on patients who underwent revision SA for failed primary arthroplasty at a single institution between 2009 and 2021 with a minimum of 2-years follow-up. Data was collected from medical records, including type of arthroplasty (anatomic total SA [TSA], reverse total SA [RSA], or hemi-SA [HSA]), demographics and patient-specific information, functional measurements, and implant survival. Patient reported outcomes were obtained during follow-up by phone.
Results:
The mean age at index and revision surgeries was 60.5 ± 12.1 years and 64.8 ± 11.1 years, respectively, and average total follow-up was 5.5 ± 3.5 years. The average time to revision was 4.5 ± 5.2 years (range 0.01-24.5 years). Among 99 revision shoulder arthroplasty procedures, 28 were TSA/HA to TSA/HA, 51 were TSA/HA to RSA, 18 were RSA to RSA, and 2 were RSA to HA. Revision surgery significantly improved functional outcomes in forward elevation (preoperative: 79.8 ± 41.0 vs postoperative: 118.5 ± 38.3; p < 0.001), external rotation (preoperative: 27.8 ± 19.3 vs postoperative: 34.3 ± 16.2; p = 0.028), internal rotation (preoperative: glute vs postoperative: S1; p = 0.002), and forward elevation strength (preoperative: 4+/5 vs postoperative: 5/5; p = 0.002). Postoperative patient reported outcomes included: VAS pain (2.2 ± 2.9), SANE (72.6 ± 21.5), ASES (73.3 ± 20.4), and SST (7.7 ± 2.8) scores. The overall 2-, 5-, and 10-year post-revision implant survival rate was 85.48%, 83.06%, and 79.84%, respectively. Patients who had an initial RSA and were revised to RSA were at higher risk of implant failure and subsequent re-revision (RSA to RSA: 1.5 ± 2.5 years vs. TSA/HA to RSA: 2.5 ± 2.1 years vs. TSA/HA to TSA/HA: 4.0 ± 3.5 years; p = 0.0046).
Conclusion:
Revision shoulder arthroplasty improved patient outcomes post-index arthroplasty failure. Revisions were more likely to be successful when revising from TSA/HA to RSA.
Level Of Evidence:
Level III - retrospective comparative study.
