Several studies have evaluated total hip and knee arthroplasty in solid organ transplant (SOT) patients; however, there are limited studies evaluating shoulder arthroplasty in SOT patients. This study compares the complications and functional outcomes of SOT patients undergoing shoulder arthroplasty with a matched control group. The institution's database was retrospectively reviewed for patients with a history of SOT undergoing primary shoulder arthroplasty (with minimum 2-year follow-up) and compared with a control group matched for age, sex, preoperative diagnosis, and surgical procedure. Preoperative and postoperative range of motion and outcome scores, perioperative surgical and medical complications, hospital length of stay, and mortality were compared. Fifteen patients with previous SOT underwent 19 shoulder arthroplasties. Thirty-four underwent 35 shoulder arthroplasties in the control group. At last follow-up, the SOT group had a significantly worse UCLA score. The SOT group had a significantly worse improvement in UCLA, active elevation, and passive elevation scores in pre- to postoperative scores. There was no difference in length of stay, infection, or surgical complications. Ninety-day readmissions, medically related complications, and required blood transfusion were significantly higher in the SOT group. There was increased mortality in the SOT compared with the control group (death occurred on average 1577 days after arthroplasty). Shoulder arthroplasty in patients with previous SOT appears safe and effective for degenerative shoulder disorders. Patients should be counseled preoperatively that their range of motion and function may not improve as much as their nontransplant cohorts. SOT patients may have increased incidence of postoperative blood transfusions and medically related complications.
