Abstract

Background

The ligamentum teres (LT) has received attention in patients undergoing hip arthroscopy (HA) for femoroacetabular impingement (FAI). Indeed, a better understanding of the function of the LT and its implications for clinical outcomes in the presence of a torn LT is required. This systematic review analyses the patient-reported outcome measures (PROMs) and the complication rate when an intact or torn LT is encountered during HA for FAI.

Methods

Studies that compared patients with an intact to those with a torn LT managed with debridement during hip arthroscopy for FAI were identified from the Web of Science, PubMed, and Embase. The minimum follow-up for inclusion was 24 months. The Risk of Bias in Non-randomised Studies of Interventions (ROBINS-I) tool was used to assess the risk of bias. Patient characteristics and PROMs were assessed at the baseline and last follow-up.

Results

The systematic review identified two studies comprising 611 patients. No statistically significant difference was found in pain, Harris Hip Score, and the activities of daily living and sports subscales of the Hip Outcome Score between patients with an intact LT and those with a torn LT treated with debridement, both of whom underwent HA for FAI.

Conclusions

In patients undergoing arthroscopic management for FAI, an intact or torn ligamentum teres managed with debridement does not influence postoperative PROMs. Given the importance of the LT as a structure of the hip joint and the increasing interest in HA for FAI, further standardised studies will be a valuable source for surgeons encountering this pathology.

The role of the ligamentum teres in congenital dislocation of the hip (1970). The authors proposed an analogy for the role of the ligamentum capitis femoris (LCF) as a “ball and chain control” and noted that it can spontaneously reduce congenital hip dislocation. The text in Russian is available at the following link: 1970MichaelsG_MatlesAL . [ii]   Original text Quote p. 199 Many papers in the literature have implicated the ligamentum teres as a hindrance to the late open reduction of a congenitally dislocated hip. Occasionally the ligamentum teres has been reported to be absent. However, in most cases it is hypertrophied and elongated. Our present knowledge confirms the fact that congenital dislocation of t...

Catalog. Classifications of LCF Pathology

  The classifications are intended to systematize of ligamentum capitis femoris pathology and assist in the development of general approaches to its description, registration, analysis and treatment.   Keywords ligamentum capitis femoris, ligamentum teres, ligament of head of femur, hip joint, histology, pathological anatomy, pathology, trauma INTRODUCTION In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. The development of arthroscopic surgery has made it possible to identify various, previously undescribed types of LCF pathology, which prompted the development of various modern classifications based on intraoperative observations. Analysis of literature data and our own morphological observations allowed us to propose a General Classification of the Ligamentum Teres Pathology, which has the form of a collection of classifiers, as well as a Classification of Functions of the Ligamentum Teres.
