Purpose: 

To synthesize contemporary evidence on definitions, diagnosis, imaging, management, and outcomes in hip microinstability and to propose a phenotype-guided framework grounded in the labrum-capsule-ligamentum teres (LT) stability continuum.

 

Mechanistically, capsular ligaments provide the primary rotational and translational restraints across most of the arc of motion, with the labrum and ligamentum teres serving as secondary stabilizers.24 The relative contribution of the ligamentum teres increases in positions of high flexion with adduction and external rotation, which helps explain the position-dependent increases in excursion observed following capsular injury or insufficiency.24 This ligament-angle relationship aligns with clinical observations of apprehension and giving-way in provocative positions, underscoring the rationale for measured capsular management and labral seal restoration in surgical treatment algorithms.24

 

Ligamentum Teres

The ligamentum teres (LT) augments stability by resisting distraction and constraining rotation at high flexion angles.39,40 Although the LT’s contribution to microinstability is adjunctive rather than primary, LT pathology is observed frequently in athletes who perform extreme ROM.41 Addressing LT lesions in the context of optimized capsulolabral management leads to symptomatic improvement.42,43

 

Ligamentum Teres—Function, Indications, and Outcomes

The LT provides measurable end-range rotational restraint and contributes to distraction resistance, particularly in high flexion/adduction/external-rotation positions.39,40 Debridement may relieve symptoms from partial or degenerative tears; LT reconstruction (auto/allograft) is reserved for refractory instability after labral and capsular optimization.42

Systematic reviews and ≥ 2-year series report short-term improvements in PROs, with reoperation rates of approximately 10–20% and limited long-term survivorship data.42,99 LT reconstruction better serves as an adjunct rather than a primary stabilizing procedure.43,100 RTS following LT reconstruction is inconsistent and commonly reported to be around 40–60% in available series.43,100 Given variable outcomes and lower-level evidence, LT reconstruction is best viewed as an adjunctive procedure rather than a stand-alone stabilizer.

Biomechanically, LT contribution is modulated by structural morphology (length, cross-sectional area, and insertional integrity) and by the status of the capsulolabral complex.39,40 Shorter or thicker LTs tend to demonstrate greater stiffness and higher load-to-failure, whereas attenuated ligaments engage later and tolerate lower loads, predisposing to earlier terminal rotation.39,40 For these reasons, LT reconstruction is most rational when (1) labral seal and capsular function have been optimized but symptomatic end-range rotational laxity persists, (2) imaging or arthroscopy documents marked LT attenuation or partial absence, and (3) intraoperative testing shows persistent excess terminal rotation or drive-through despite repair and plication.42,43 Routine primary LT reconstruction is not supported by high-level evidence; morphology-informed selection (MRI/arthroscopic measurement of LT length and cross-sectional area (CSA) plus quantitative intraoperative rotation testing) strengthens mechanistic justification and should be incorporated into future comparative studies.

 

Future progress hinges on standard definitions, objective laxity measurement, multicenter comparative-effectiveness- research, and rehabilitation trials tailored to microinstability—with specific attention to the unanswered role of dynamic stabilizers and the durability of LT reconstruction and femoral head-neck remplissage.16,53,59,66,115

Approximately 4% of patients treated with the modified Dunn procedure develop postoperative hip instability, with common causes including capsular laxity, resection of the ligamentum teres, and excessive shortening of the femoral neck.[5] It is clinically crucial to be cautious of residual laxity, as it may compromise postoperative stability, joint congruence, and functional outcomes if left unaddressed.[5]

Delayed treatment may lead to structural changes such as inverted labrum, hypertrophied ligamentum teres, pulvinar tissue, and capsular tightening.

Both autograft and allograft tissues have been successfully used for labral reconstruction, including graft sources such as the iliotibial band, gracilis tendon, and ligamentum teres. In particular, circumferential allograft reconstruction (in which the graft replaces the labrum around the entire acetabular rim) has demonstrated excellent mid-term outcomes and low failure rates in both primary and revision hip arthroscopy settings. 25

Abstract:

An experimental technique for reconstruction of the ligamentum capitis femoris (ligamentum teresfemoris) is described. The proposed method involves creating two portions of the ligament analog:a pubic portion and an ischial portion. Fixation of these portions is performed in ischial and pubictunnels drilled in the corresponding pelvic bones. The technique was tested on a hip joint model.In arthroscopic reconstruction, it is proposed to provide visualization through the inferior approachand the femoral tunnel without distraction in the joint.

Conclusion.

In the case of hip-femoral joint injury, the development of sharp morphological changes in the ligament of the head of the femur, the tendon inside the acetabulum, the tendon covering the femur head, and then in the synovial membrane of the joint bag, the deepening of destructive and degenerative changes is an irreversible process and is considered the main indication for endoprosthesis.

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

Arkhipov Keywords: ligamentum capitis femoris, ligamentum teres, ligament of head of femur, abductor muscle group, role,  function, hip joint, model, biomechanics, walk, gait cycle, single-legged stance  ABSTRACT New experimental and clinical data on the function of the ligamentum capitis femoris (LCF) and its participation in maintaining an erect posture were obtained. It was established that this anatomical element is involved in constraining the hip joint adduction and may fi x the joint in the frontal plane, turning it into an analogue of a second-class lever. In both unstrained one-support and asymmetrical two-support orthostatic postures, when the LCF is stretched and the abductor muscle group is exerted, a load equal to the body weight is evenly distributed between the upper and lower hemispheres of the caput femoris. In addition, the LCF fu...
