Situation

Optimizing regional analgesia in primary total hip arthroplasty (THA) is essential for rapid same-day ambulation. This prospective randomized controlled trial compared dual-glucocorticoid anterior quadratus lumborum and lateral femoral cutaneous nerve blocks with periarticular local infiltration analgesia (PALIA).

Background

Interfascial plane blocks have gained popularity for somatic and visceral hip denervation, but whether specialized ultrasound-guided regional nerve blocks provide tangible analgesic or functional benefits over surgeon-administered periarticular infiltration remains contentious.

Assessment & Findings
  • Study Design & Cohort: Prospective randomized trial of 192 patients (188 analyzed; mean age 61 years, 46% male) undergoing primary THA receiving either ultrasound-guided aQLB plus LFCN block or intraoperative PALIA. Both cohorts received standardized dual glucocorticoids (10 mg dexamethasone sodium phosphate + 80 mg methylprednisolone acetate) mixed with 60 mL 0.2% ropivacaine.
  • Primary Opioid Consumption: Inpatient opioid consumption on postoperative day (POD) 1 demonstrated no statistically significant difference between aQLB+LFCNB (median 29.84 oMME; IQR 17.72 to 38.75) and PALIA (median 30.50 oMME; IQR 18.00 to 42.00; P = 0.57).
  • Functional Recovery & Pain Trajectories: Postoperative day 2 opioid use, Brief Pain Inventory (BPI) severity and interference scores, and functional mobility (AMPAC and PROMIS scores) showed no significant differences from POD 0 through 1 year.
  • Metabolic Profiles: POD 1 fasting serum glucose was slightly lower in the aQLB+LFCNB cohort (median 141.5 vs 153.0 mg/dL; P = 0.003), but no clinical hyperglycemic complications occurred.
Recommendation & Practice Takeaway

Clinical Pearl: Complex ultrasound-guided anterior quadratus lumborum and lateral femoral cutaneous nerve blocks offer no superior analgesia, opioid reduction, or functional acceleration over direct surgeon-administered periarticular local infiltration (PALIA) containing dual glucocorticoids. Surgeons can comfortably rely on rapid, meticulous capsular and pericapsular infiltration without adding pre-incision regional anesthesia delays or block-associated logistical costs.

2. Efficacy of Intraosseous Tranexamic Acid in Primary Total Hip Arthroplasty: A Prospective Randomized Controlled Trial

Authors: Chen Y, Cao L, Ji B, Li G, Zhang X | Journal: The Journal of Arthroplasty (Oct 2026) | View Source / DOI

Situation

Blood conservation in primary total hip arthroplasty (THA) relies heavily on antifibrinolytic therapy. This randomized controlled trial evaluated whether direct intraosseous (IO) tranexamic acid (TXA) administration is noninferior to conventional intravenous (IV) or topical delivery routes.

Background

While IV and topical TXA are widely utilized, bleeding in THA originates predominantly from rich cancellous bone beds of the acetabulum and femoral canal. Direct trabecular bone delivery has been proposed to enhance immediate local clot stabilization with minimal systemic plasma concentration peaks.

Assessment & Findings
  • Study Design & Cohort: Prospective, equal-proportion noninferiority randomized trial of 126 patients undergoing primary THA randomized to (1) intraosseous TXA (20 mg/kg delivered into cancellous bone of femur and ilium), (2) intravenous TXA (20 mg/kg 5 minutes prior to incision), or (3) topical TXA (20 mg/kg applied prior to closure).
  • Hemoglobin Drop & Bleeding: Hemoglobin drop from baseline was equivalent across all three cohorts on the day of surgery (DOS) and POD 1 through 3 (all P > 0.40). Exploratory analyses revealed significantly lower calculated total blood loss in the IO cohort on DOS and POD 1 compared with IV and topical groups (P = 0.005 and 0.016).
  • Transfusion & Adverse Events: Allogenic transfusion rates were 2.3% in IO, 7.1% in IV, and 2.3% in topical cohorts (P = 0.434). Zero deep vein thromboses, pulmonary embolisms, or surgical site infections occurred in the intraosseous cohort.
Recommendation & Practice Takeaway

Clinical Pearl: Intraosseous application of tranexamic acid directly into cancellous acetabular and proximal femoral bone provides noninferior blood conservation compared to standard intravenous and topical regimens. IO administration represents a highly viable delivery strategy, particularly in patients with difficult intravenous peripheral access or when systemic antifibrinolytic exposure warrants minimization in complex vascular pathology.

3. Systematic Review of Wound Complications After Direct Anterior Approach Total Hip Arthroplasty: Incidence, Risk Factors, and Management Strategies

Authors: Subramanian T, Oles A, Halayqeh S, Mazzucco M, Jolissaint J et al. | Journal: The Journal of the American Academy of Orthopaedic Surgeons (Oct 2026) | View Source / DOI

Situation

The direct anterior approach (DAA) for total hip arthroplasty provides muscle-sparing intermuscular access and rapid early recovery, but groin wound complications remain a recognized concern. This systematic review and meta-analysis characterized complication incidence, patient risk factors, and the protective effect of bikini versus longitudinal incisions.

Background

Proximity to the inguinal skin crease and potential perspiration in obese patients with abdominal pannus increase wound shear stress. Establishing whether transverse (bikini) incisions mitigate surgical site complications is crucial for optimizing anterior approach safety.

Assessment & Findings
  • Study Design & Cohort: Systematic review and meta-analysis across 8 biomedical databases adhering to PRISMA guidelines, analyzing 36 clinical studies comprising 35,300 primary DAA total hip arthroplasties.
  • Incidence of Wound Events: Overall complication rates remained low: superficial wound dehiscence occurred in 1.41%, superficial surgical site infection in 1.34%, delayed healing in 1.15%, and hematoma/seroma in 0.80%.
  • Incision Morphology Meta-Analysis: Pooled meta-analysis demonstrated that transverse (bikini) groin crease incisions reduced wound complication risk by 55% compared with traditional longitudinal incisions (relative risk [RR] 0.45; 95% CI, 0.23 to 0.89; P = 0.0219).
  • Patient-Level Risk Factors: Elevated BMI (obesity) and female sex were the most prominent independent risk factors for wound compromise. Over 90% of superficial healing issues responded successfully to conservative local wound care without surgical revision.
Recommendation & Practice Takeaway

Clinical Pearl: Utilizing a transverse (bikini) incision oriented along Langer tension lines cuts wound complication risk by more than half compared to traditional longitudinal incisions during direct anterior THA. Surgeons adopting the DAA in female patients or patients with elevated BMI should strongly consider the bikini approach to optimize healing and avoid distal incision tension across the femoral flexion crease.
