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.

  «Prof. Partridge in his lectures on anatomy at King's College was accustomed to compare the Ligamentum Teres, in its function, to the leathern straps by which the body of a carriage is suspended on springs » ( 1874SavoryWS ). Perhaps Nikolai Pirogov listened to these lectures ( 1859PirogoffN ).   The analogy that Richard Partridge used could have arisen after reading the monograph Bell J. The Principles of Surgery (1801) . In it, the author depicted a cart and a pelvis resting on the head of one and two femurs. However, there is no mention of ligamentum capitis femoris (LCF) in the chart descriptions. References Savory WS. On the use of the ligamentum teres of the hip joint.

Fragment from the book Platter F. Observationum (1614). The author notes the role of the ligamentum capitis femoris (LCF) in fixing the femur in the acetabulum and the possibility of its lengthening  (synovitis) . Quote pp. 141-142 [Lat] Cruris dextri astrictio & contractio, post coxendicum dolorem. Cùm enim ligamentum illud articulum circumd ás, omnium totius corporis ligamentorum, quae articulos ambiunt, sit amplissimum; fieri potest, ut adeò cedat, ut (sicuti saepe sit) femoris caput, è suo sinu devoluatur, & in membranae illius (quae cùm erassissima sit, prae omnibus totius corporis ligamentis, nunquam vi qualicunque disrumpi potest) amplitudine seu capacitate subsistat, elongato simul & vehementer attracto, tereti illo & crasso, quod caput aliàs in suo sinu retinere solet, ligamento.
