Hip arthroscopy in obese, a successful combination?

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomedical Engineering

Background:

• Hip arthroscopy is increasingly popular for treating hip conditions.
• The impact of obesity on hip arthroscopy outcomes remains a significant clinical question.
• Limited data exists comparing outcomes between obese and non-obese patients.

Purpose of the Study:

• To systematically review and synthesize existing literature on hip arthroscopy outcomes in obese versus non-obese patients.
• To evaluate the influence of body mass index (BMI) on revision rates and patient-reported outcome scores after hip arthroscopy.

Main Methods:

• A systematic literature search was conducted on Pubmed/Medline.
• Three studies comparing hip arthroscopy outcomes across different BMI groups were included.
• Data were extracted and pooled using Review Software Manager, calculating weighted mean differences and odds ratios (OR).

Main Results:

• Obese patients had significantly higher rates of conversion to total hip replacement (OR=2.21) and re-arthroscopy (OR=4.68).
• Overall reoperation rates were higher in the obese group (OR=2.87).
• Obese patients reported lower scores on the Non Arthritic Hip Score and modified Harris Hip Score, with clinically relevant differences.

Conclusions:

• Obesity negatively impacts hip arthroscopy outcomes, evidenced by increased reoperation rates and lower subjective scores.
• Despite similar improvements, obese patients experience poorer functional outcomes post-hip arthroscopy.
• Further research is needed to optimize surgical strategies for obese patients undergoing hip arthroscopy.
