Theodoulou A, et al. - In this systematic review, researchers intended to examine the impact of obesity on outcomes after total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA). The findings implied that after TSA or RTSA, heightened odds of dislocation, fracture, and revision was seen in individuals who were obese. Inversely, on the odds of an unscheduled return to the operating theater, obesity had no impact. In individuals who were obese, postoperative forward flexion varied from those who were not obese, nonetheless, no variations in other functional measures including abduction and external rotation were discovered. However, individuals who were obese recorded significantly higher levels of pain, the variation was not clinically appropriate. In summary, while recognizing elective TSA or RTSA, surgeons should acknowledge advising individuals who are obese of the greater risk of dislocation, fracture, and revision. Findings are restricted by confounding variables however extending the understanding of extra risks related to preexisting obesity, which would encourage better-informed decisions former to proceeding with surgery.
