Background

Hip arthroscopic surgery for borderline hip dysplasia remains controversial. This study explores whether an intact ligamentum teres (LT) improves long-term outcomes for patients with borderline dysplasia.

Methods

Patients with borderline dysplasia and either an LT tear or intact LT underwent hip arthroscopic surgery. They were matched in pairs based on age, sex, and other factors, and their outcomes were compared after 5 years.

Key Findings

Patients with an intact LT had better mental health outcomes and were more likely to achieve a “patient acceptable symptomatic state” (PASS) for hip function. Overall, both groups had favorable outcomes, but the group with an intact LT performed better in some aspects.

Conclusions

An intact ligamentum teres is associated with better long-term hip function and mental health outcomes after hip arthroscopy for borderline dysplasia.

What Does This Mean for Patients

If you have borderline hip dysplasia and an intact ligamentum teres, you may have a better chance of achieving optimal results from hip arthroscopic surgery.
