Return to previous activity level for non-athlete patients after periacetabular osteotomy

Area of Science:

• Orthopedic surgery
• Hip reconstruction
• Biomechanical analysis

Background:

• Periacetabular osteotomy (PAO) is a rising surgical technique for hip dysplasia.
• Acetabular reorientation aims to improve hip joint function and alleviate pain.

Purpose of the Study:

• To evaluate recovery timelines after PAO in non-athletic patients with hip dysplasia.
• To assess return to activities, driving, and pain-free full weight-bearing post-surgery.

Main Methods:

• Retrospective review of 40 non-athletic patients undergoing PAO (2018-2022).
• Analysis of radiographic parameters including center-edge angles and joint space width.
• Evaluation of clinical outcomes and return to function.

Main Results:

• Patients returned to pre-surgery activity levels in an average of 4.5 months.
• Pain-free full weight-bearing was achieved in an average of 3.4 months.
• Significant improvements in radiographic parameters (e.g., lateral center-edge angle) and clinical scores were observed.

Conclusions:

• PAO leads to improved radiographic measures and functional outcomes in hip dysplasia patients.
• Non-athletic individuals typically resume activities within 4.5 months and achieve pain-free ambulation in 3.4 months.
• Preoperative joint space narrowing correlates with longer pain-free weight-bearing duration.
