[The weight-loss injection : An orthopaedic overview].

Abstract

Background: The increasing prevalence of obesity represents a significant and growing challenge in orthopaedic surgery. This is particularly true for patients with morbid obesity, who have a significantly increased risk of postoperative complications. The newer incretin-based therapies (such as semaglutide and tirzepatide), these so-called "weight loss injections", offer promising potential for preoperative weight reduction and minimisation of peri- and postoperative complications.

Study situation: However, the evidence regarding their influence on postoperative outcomes is inconsistent. Retrospective studies suggest that rapid weight loss immediately prior to orthopaedic surgery may increase the risk of complications, including septic shock and revision surgery. Meta-analyses, on the other hand, indicate potential protective effects in surgical outcomes with prior long-term weight reduction.

Conclusion: There are currently no sufficiently qualitative studies on the safety and efficacy of these new drugs in the orthopaedic surgery sector. An individualised and multidisciplinary approach, therefore, remains relevant in order to achieve an optimal surgical outcome for the individual patient.
