Discrepancy seen between patient satisfaction, implant survival after shoulder arthroplasty
Although investigators found high implant survival rates among patients following shoulder arthroplasty, they discovered lower patient satisfaction rates. In addition, researchers found total shoulder arthroplasty yielded better implant survival and patient satisfaction rates than hemiarthroplasty.
Researchers evaluated patient-reported outcomes and implant survival rates in 71 patients, aged 50 years or younger, who underwent either hemiarthroplasty (HA) or total shoulder arthroplasty (TSA). Investigators contacted patients via email or telephone with a follow-up questionnaire documenting American Shoulder and Elbow Surgeons, Simple Shoulder Test, VAS and Subjective Shoulder Value scores.
Patient satisfaction was determined from two binary questions about patients’ willingness to undergo the procedure and whether their shoulders improved with the procedure. Patient satisfaction failure was defined as a negative response to either question. Investigators used Kaplan-Meier to calculate survival rates for outcome failure with regard to revision surgery for TSA conversion, patient satisfaction failure and resection arthroplasty.
Findings showed that at 5 years, the Kaplan-Meier survival rate for patient satisfaction following HA was 71.6% and was 95% after TSA. Investigators noted clinical failure was seen in 22% of HA cases and in 7% of TSA cases. The Kaplan-Meier implant survival rate at 5 years was 89% for HA and 95% for TSA. According to results from multivariable regression analysis, the primary factor for patient satisfaction failure was postoperative pain. ‒ by Monica Jaramillo
