Endoscopy-Assisted Periacetabular Osteotomy.

Area of Science:

• Orthopedic surgery
• Minimally invasive surgical techniques
• Hip arthroscopy

Background:

• Periacetabular osteotomy (PAO) is crucial for hip preservation.
• Minimizing soft tissue disruption and improving visualization are key challenges in PAO.
• Current techniques may involve extensive dissection, increasing complication risks.

Purpose of the Study:

• To introduce and evaluate the endoscopy-assisted periacetabular osteotomy (PAO) technique.
• To demonstrate the benefits of reduced soft tissue dissection and enhanced visualization.
• To assess the application of this method for hip dysplasia and acetabular retroversion.

Main Methods:

• A staged surgical approach combining hip arthroscopy and mini-open PAO.
• Utilizing endoscopic and fluoroscopic guidance during the osteotomy.
• Performing a final dynamic hip arthroscopy for assessment and potential femoroplasty.

Main Results:

• Achieved minimized soft tissue dissection.
• Improved visualization of vital anatomical structures.
• Successfully treated hip dysplasia and acetabular retroversion in a minimally invasive manner.

Conclusions:

• Endoscopy-assisted PAO offers a viable minimally invasive alternative.
• This technique enhances visualization and reduces dissection, potentially improving patient outcomes.
• It is effective for treating specific hip pathologies like dysplasia and acetabular retroversion.
