GLP-1 Receptor Agonists and Orthopaedic Surgery¶
How GLP-1 receptor agonists (semaglutide and related drugs) affect orthopaedic and arthroplasty patients — perioperative risk, weight optimisation, bone and fracture healing, and infection or revision risk.
Overview¶
Glucagon-like peptide-1 (GLP-1) receptor agonists are increasingly utilized in orthopaedic practice, particularly for preoperative weight loss in patients with obesity and type-2 diabetes mellitus [5]. Arthroplasty surgeons will encounter a growing number of patients on these agents, necessitating an understanding of their perioperative implications [3]. While GLP-1 receptor agonists affect bone health and carry specific implications for spine surgery, their role in joint arthroplasty is defined by evolving outcome data [1].
Current evidence suggests that perioperative GLP-1 receptor agonist use in total hip or knee arthroplasty is associated with improved early surgical outcomes and decreased resource utilization [7]. These patients may also experience a reduced risk of postoperative infection and reduced readmission risk following joint arthroplasty, without evidence of increased postoperative medical harm [6]. However, findings remain inconsistent regarding broader complications; while some data indicate no significant association with 90-day or 2-year adverse events following total shoulder arthroplasty, further research is needed to clarify their impact on outcomes and establish standardized perioperative management guidelines [2, 4].
Regarding skeletal health, GLP-1 receptor agonists may provide benefits in type 2 diabetes mellitus by addressing mechanisms underlying diabetic osteopathy, with effects varying by agent type and treatment duration [16]. Exenatide is identified as the best option regarding fracture risk among this class [11]. Conversely, further investigation is required to elucidate the association between GLP-1-RA use and increased incidence of osteoarthritis diagnosis in patients with no preexisting osteoarthritis [15]. Due to the risks of hyperglycaemia and compromised weight control, elective preprocedural cessation of GLP-1 receptor agonists is not recommended due to insufficient data supporting cessation [10]. High-quality studies are needed to address optimal perioperative care for this expanding patient population [8, 9].
Effects on Surgery and Recovery¶
Arthroplasty Outcomes: Current observational data indicate that perioperative GLP-1 RA use in patients undergoing total hip or knee arthroplasty is not associated with a consistent increase in short-term revision rates [8]. GLP-1RA use was associated with improved early surgical outcomes and decreased resource utilization following total hip arthroplasty (THA) and total knee arthroplasty (TKA) [7]. Perioperative GLP-1 RA use in patients undergoing total hip or knee arthroplasty may be associated with a reduced risk of postoperative infection [8]. A meta-analysis of eight retrospective cohort studies involving over 76,000 arthroplasty patients found that GLP-1 RA use was associated with reduced risk of prosthetic joint infection (PJI) [18]. Preoperative glucagon-like peptide-1 receptor agonist use may be linked to reduced readmission risk following joint arthroplasty, without evidence of increased postoperative medical harm [6]. GLP-1 agonist use is not significantly associated with 90-day or 2-year adverse events following total shoulder arthroplasty [2].
Soft-Tissue and Hand Surgery: Perioperative GLP-1RA use was associated with a small yet statistically significant reduction in the odds of wound dehiscence following carpal tunnel release (CTR) [17]. Perioperative GLP-1RA use did not increase the odds of any other 90-day postoperative complications following carpal tunnel release (CTR) [17].
Gastric Aspiration Risk: Patients treated with GLP-1 RAs may retain considerable gastric contents even after standard preoperative fasting, thereby increasing the likelihood of regurgitation and aspiration during anesthesia induction or emergence [12]. Most studies reported an association between GLP-1 RA and increased residual gastric contents, but evidence linking these medications to a statistically significant rise in regurgitation or aspiration events remains highly inconsistent [20]. Available observational evidence suggests that extended GLP-1 RA withholding, 24-hour clear liquid diets, and pre-procedural gastric POCUS may be associated with reduced residual gastric content in selected patient populations [19].
Perioperative Management and Research Gaps: Elective preprocedural cessation of GLP-1RAs and GLP-1/GIPRAs is not recommended due to insufficient data supporting cessation and risks of hyperglycaemia and compromised weight control [10]. While GLP-1 receptor agonists show potential to reduce postoperative complications in total joint arthroplasty, findings remain inconsistent, and further research is needed to clarify their impact on outcomes and establish perioperative management guidelines [4]. Conflicting findings highlight the need for further research, particularly well-designed multicenter studies and randomized controlled trials, to clarify the effects of GLP-1 RAs on surgical outcomes [13]. Further investigation is needed to elucidate the association between GLP-1-RA use and the increased incidence of osteoarthritis diagnosis and conversion to TKA in patients with no preexisting OA [15].
Practical Considerations¶
GLP-1 receptor agonists serve as a promising tool for preoperative weight loss in patients with obesity and type-2 diabetes mellitus undergoing orthopaedic surgery [5]. Semaglutide and other agents may increase the pool of eligible candidates for elective total joint arthroplasty by enabling weight loss and improving diabetic control [14]. These medications may potentially reduce postoperative complications such as sepsis and prosthetic joint infections [14].
In patients undergoing total hip or knee arthroplasty, GLP-1RA use is associated with improved early surgical outcomes [7] and decreased resource utilization [7]. Preoperative use may be linked to reduced readmission risk following joint arthroplasty [6] and is not associated with evidence of increased postoperative medical harm [6]. Current observational data suggest that perioperative GLP-1 RA use is not associated with a consistent increase in short-term revision rates [8]. Perioperative use may also be associated with a reduced risk of postoperative infection [8].
For total shoulder arthroplasty, GLP-1 agonist use is not significantly associated with 90-day adverse events [2] or 2-year adverse events [2]. Exenatide is the best option agent with regard to the risk of fracture among GLP-1 receptor agonists [11].
Patients treated with GLP-1 RAs may retain considerable gastric contents even after standard preoperative fasting [12]. This retention increases the likelihood of regurgitation and aspiration during anesthesia induction or emergence [12].
Elective Preprocedural Cessation: Not recommended due to insufficient data supporting cessation [10]. Cessation is not recommended due to risks of hyperglycaemia [10]. Cessation is not recommended due to risks of compromised weight control [10].
Findings regarding the potential for GLP-1 receptor agonists to reduce postoperative complications in total joint arthroplasty remain inconsistent [4]. Further research is needed to clarify the impact of GLP-1 receptor agonists on outcomes in total joint arthroplasty [4]. Further research is needed to establish perioperative management guidelines for GLP-1 receptor agonists in total joint arthroplasty [4]. Conflicting findings regarding the effects of GLP-1 RAs on surgical outcomes highlight the need for further research [13]. Further well-designed multicenter studies are needed to clarify the effects of GLP-1 RAs on surgical outcomes [13]. Further randomized controlled trials are needed to clarify the effects of GLP-1 RAs on surgical outcomes [13]. High-quality studies are needed to address the optimal perioperative care of patients on GLP-1RAs [9].
