Background
Hip arthroscopy in borderline dysplasia is controversial. The effect of ligamentum teres (LT) tears on outcomes has not been studied in this context.
Methods
Match-controlled study of 40 patients with borderline dysplasia (LCEA 18–25°), comparing those with and without LT tears. All underwent labral treatment and capsular plication, and outcomes were assessed over at least two years.
Key Findings
- LT tear group showed trends toward lower functional scores (mHHS, NAHS).
- Higher rates of revision (5 vs. 1) and conversion to total hip arthroplasty (3 vs. 0) in LT tear group.
- No statistically significant differences in outcome scores, but results suggest clinical relevance.
Conclusions
LT tears may signal underlying instability in borderline dysplastic hips and lead to slightly worse outcomes. These patients may be more prone to further surgical intervention.
What this means for patients
- LT tears may predict worse recovery after hip arthroscopy in borderline dysplasia.
- Patients may face higher chances of needing additional surgery or hip replacement.
- Surgeons may consider more extensive stabilization procedures up front.
