Background
This study examines the impact of complete ligamentum teres (LT) tears on patient outcomes following hip arthroscopy for femoroacetabular impingement (FAI) and labral tears.
Methods
18 patients with complete LT tears were matched to 54 controls without LT tears. Patients were evaluated with modified Harris Hip Score (mHHS), Non-arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), International Hip Outcome Tool-12 (iHOT-12), and visual analog scale (VAS) for pain. The rate of conversion to total hip arthroplasty (THA) was also assessed.
Key Findings
Patients with LT tears showed significant improvement in PRO scores post-surgery, though their improvements were less than controls, particularly on the HOS-SSS. Patients with LT tears were three times more likely to require THA.
Conclusions
Complete LT tears in hip arthroscopy patients are associated with higher rates of conversion to THA. Despite significant improvements in functional scores, these patients are considered at higher risk for long-term joint failure.
What Does This Mean for Patients
Patients with complete LT tears undergoing hip arthroscopy for FAI and labral tears should be aware that while functional outcomes can improve, they face a higher risk of needing a THA in the future.
