Comparison of Complications in X-Ray Versus Ultrasound-Guided Hip Arthroscopy
Abstract
PURPOSE: To report the complication rates and frequency of iatrogenic injury to the cartilage and labrum when using an ultrasound-guided hip arthroscopic technique compared with the standard x-ray-guided technique.
METHODS: In this retrospective cohort study of prospectively collected data, intraoperative videos were evaluated for iatrogenic injury during portal establishment. Postoperative complications and revision procedures were monitored for 12 months.
RESULTS: The study included 460 patients, with 38% in the ultrasound cohort. Video review showed a 2% complication rate of femoral head scuffing and <2% labral injury in both techniques, with no significant difference between techniques in cartilage injury (P = .90) or labrum puncture (P = .41). Six patients underwent revision procedures, 2 in the x-ray group and 6 in the ultrasound group. One patient developed a deep infection postoperatively. There were no other major complications.
CONCLUSION: Ultrasound-guided hip arthroscopy is a safe alternative to the standard x-ray-guided procedure in patients with a BMI less than 35.
LEVEL OF EVIDENCE: III, retrospective cohort.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 460 participants or records.
