Less time between TSA surgeries may optimize postoperative function, satisfaction for bilateral patients
Patients undergoing bilateral total shoulder arthroplasty may have optimized postoperative functional outcomes and satisfaction if the second surgery is performed within 6 months of the first arthroplasty, according to results.
Researchers categorized the shoulders of patients who underwent bilateral total shoulder arthroplasty (TSA; 82 shoulders) for osteoarthritis into the following groups:
patients who underwent the second TSA fewer than 6 months after the first TSA;
patients who underwent the second TSA 6 months to 12 months after the first TSA;
patients who underwent the second TSA 12 months to 24 months after the first TSA;
patients who underwent the second TSA more than 24 months after the first TSA.
Researchers compared postoperative patient-reported outcomes, biometrics and a subjective questionnaire between these four groups.
Results showed a mean postoperative University of California, Los Angeles (UCLA) score of 29, a Constant score of 72 and a Simple Shoulder Test score of 9 points. Researchers noted satisfaction with both shoulders was reported by 83% of patients. Researchers found significantly better UCLA scores among patients with fewer than 6 months between surgeries vs. patients with a 6-month to 12-month interval. Patients with fewer than 6 months between surgeries also had greater Constant scores compared with all other groups, as well as greater Simple Shoulder Test scores compared with patients with a 6-month to 12-month interval and patients with a 12-month to 24-month interval, according to results. Researchers noted no differences in length of follow-up between groups. – by Casey Tingle
