Background
- Low body mass index (BMI) in females undergoing primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) has been poorly studied.
- This study evaluates the outcomes for females with low BMI and compares them with a control group of normal BMI females.
Methods
- Female patients with a BMI under 18.5 who underwent primary hip arthroscopy for FAIS between 2008 and 2019 were included.
- Patient-reported outcomes (PROs) were collected at a minimum of two years, and these results were compared to a matched group of females with normal BMI.
Key Findings
- Females with low BMI showed significant improvement in PROs, including the modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS).
- However, they had lower rates of achieving the patient-acceptable symptom state (PASS) compared to normal BMI females.
- The low BMI group had higher rates of revision surgery, though this difference was not statistically significant.
Conclusions
- Low BMI in females undergoing hip arthroscopy for FAIS may negatively impact outcomes, as evidenced by lower rates of achieving satisfactory symptom resolution compared to those with normal BMI.
What Does This Mean for Patients
- If you're a female with low BMI considering hip arthroscopy for FAIS, it is important to understand that while surgery can improve pain and function, achieving the highest levels of satisfaction may be more challenging compared to those with normal BMI.
