Femoral de-rotation osteotomy versus hip arthroscopy for management of femoroacetabular impingement in adult patients with decreased femoral anteversion: a matched retrospective cohort study.

Femoral de-rotation osteotomy (FDO) and hip arthroscopy are both recognized surgical options for the management of femoroacetabular impingement (FAI) in the setting of decreased femoral anteversion (<5°). Minimal comparative data exist regarding the difference in outcomes between these two techniques, and we believe this is the first study to provide that comparison. This retrospective cohort study included a total of 20 patients with such pathology, matched for age, gender and body mass index. A total of 10 patients were included in the FDO group [median anteversion -0.5° (true retroversion); average follow-up 17.9 months]. In total, 10 patients were included in the hip arthroscopy group [median anteversion -0.5° (true retroversion); average follow-up 28.5 months]. Both groups demonstrated statistically and clinically significant improvement in the post-operative International Hip Outcome Tool (iHOT-33) scores [median improvement: FDO group, 37.7 points (r 14-58.8; P < 0.041); hip arthroscopy group, 35.9 points (r 11.1-81; P < 0.05)], noting that the minimal clinically important difference for the iHOT-33 is 6.1 points. However, the study was not adequately powered to delineate a difference in improvement between the two groups. The findings suggest significant improvement in patient-reported outcomes, and clinical findings can be achieved with either FDO or hip arthroscopy for FAI in the setting of decreased femoral anteversion. However, selection of the most suitable surgical procedure using a patient-specific approach may optimize outcomes in this challenging population.

Anesthesia for hip arthroscopy: a narrative review.

PURPOSE: Hip arthroscopy is a minimally invasive surgical procedure indicated for the treatment of specific hip disorders. In this narrative review, we aim to examine the key components in providing anesthesia for this procedure. SOURCE: MEDLINE(®), PubMed, and EMBASE™ databases were searched for peer-reviewed articles discussing the anesthetic management of patients undergoing hip arthroscopy. PRINCIPAL FINDINGS: The primary anesthetic regimen used for hip arthroscopy should balance patient factors, preferences of the surgeon, and the demands of the procedure itself. Both general and neuraxial anesthetic techniques are well suited for this mostly ambulatory surgical procedure. There is a lack of current literature specifically comparing the benefits and risks of the two techniques in this setting. Postoperative pain management consists mainly of intravenous and oral opioids; however, a variety of regional anesthesia techniques, such as lumbar plexus block and fascia iliaca block, can be performed pre- or postoperatively. Overall, hip arthroscopy is safe, although positioning-related difficulties, extravasation of irrigation fluid, hypothermia, infections, and thromboembolic events are potential perioperative complications that warrant specific monitoring and prompt treatment. CONCLUSIONS: Until now, the anesthetic technique for hip arthroscopy has not been well studied. Thus, increasing emphasis should be directed towards examining relevant clinical outcomes that can better inform evidence-based decision-making in the anesthetic management of hip arthroscopy patients. In the meantime, awareness of potential complications and vigilant monitoring are paramount in providing safe anesthetic care for patients undergoing hip arthroscopy.
