Fluoroscopy Learning Curve in Hip Arthroscopy-A Single Surgeon's Experience.

Area of Science:

• Orthopedic Surgery
• Medical Imaging
• Patient Safety

Background:

• Hip arthroscopy is a common procedure for femoroacetabular impingement and labral injuries.
• Minimizing radiation exposure is crucial for patient and staff safety during fluoroscopic procedures.

Purpose of the Study:

• To evaluate the impact of surgical experience on radiation dose and fluoroscopy time.
• To determine if a learning curve exists for hip arthroscopy regarding radiation exposure and procedure duration.

Main Methods:

• Retrospective analysis of the first 100 hip arthroscopy cases by a single surgeon.
• Subjects were grouped into four sets of 25 cases.
• Statistical analysis included one-way ANOVA and simple linear regression.

Main Results:

• Significant linear decrease in both radiation dose (mGy) and fluoroscopy time with increasing case number.
• Radiation dose and fluoroscopy time were significantly lower in later case groups (group 4) compared to the earliest group (group 1).
• Findings remained significant after adjusting for patient weight, height, and BMI.

Conclusions:

• A clear learning curve exists for hip arthroscopy, characterized by reduced radiation dose and fluoroscopy time.
• Surgical experience leads to improved efficiency and potentially reduced patient risk.
• Further studies can explore specific techniques contributing to this learning curve.
