Conclusion There are many risk factors associated with developing an infection after elective shoulder surgery .
The findings of this systematic review are clinical ly relevant as it has been shown that infection after shoulder surgery results in poor patient-reported outcomes and pose a significant financial burden .
Purpose Infection is a concern after all orthopedic procedures , including shoulder surgery .
This systematic review of literature aim ed to determine risk factors for infection as well as the availability and effectiveness of measures utilized to prevent infection after elective shoulder surgery .
What Are the Instability and Infection Rates After Reverse Shoulder Arthroplasty?
Background A concern regarding  reverse shoulder arthroplasty ( RSA )  is the possibly higher complication rate compared with conventional unconstrained shoulder arthroplasty . Questions / purpose sWe determined ( 1 ) the rate of instability and infection ; ( 2 ) whether diagnosis influenced instability and infection rates ; and ( 3 ) whether these complications affect ASES , Constant , and WOOS scores after RSA . Methods A prospect i ve data base , clinical charts , and radiographs of 284 patients who had undergone primary ( n = 212 patients ) or revision ( n = 72 patients ) RSA  were review ed to identify patients whose postoperative course was complicated by instability or infection . Results The rate of instability was similar in patients with primary ( eleven of 212 [ 5 % ) ] and revision ( six of 72 [ 8 % ] ) reverse arthroplasty . The rate of infection was higher in the revision ( five of 72 [ 7 % ] ) than in the primary ( three of 212 [ 1 % ] ) group . Patients with an irreparable subscapularis tendon had a higher rate of instability ( 14 of 123 [ 12 % ] ) compared with patients with a repairable subscapularis tendon ( one of 161 [ less than 1 % ] ) . The fracture sequelae group had the highest rate of instability ( seven of 25 [ 28 % ] ) among diagnoses within the primary group . The rates of infection were similar between the diagnoses within the primary group . The improvements in the ASES score , the Constant score , and the WOOS score from preoperatively to postoperatively were better in the no instability/infection group as compared with the instability/infection group . Conclusions This information confirms the available literature allowing surgeons to give patients realistic expectations regarding the infection and instability rates after RSA.Level of Evidence Level III , therapeutic study .
