Clinical overlap with femoroacetabular impingement syndrome (FAIS) and borderline dysplasia delays recognition.  \nPurpose: 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.  \nStudy Design: Narrative review.  \nMethods: Peer-reviewed literature (2000–2025) focusing on biomechanical investigations, comparative cohorts, meta-analyses, and consensus statements on microinstability, hip capsular management, borderline dysplasia, and LT pathology.  \nResults: A four-pillar diagnostic approach improves accuracy. The Abduction-Hyperextension-External Rotation (AB-HEER) and Hyperextension-External Rotation (HEER) tests provide the highest single-test accuracy among exam maneuvers, whereas the prone instability test offers high specificity to rule in. The femoroepiphyseal acetabular roof (FEAR) index aids in risk stratification for borderline dysplasia but is position-sensitive. Arthroscopy with labral preservation and complete hip capsular closure improves patient-reported outcomes (PROs) and survivorship relative to non-closure. Iatrogenic cam over-resection can precipitate microinstability; femoral headneck remplissage is a revision option to restore contour and sealing mechanics. In borderline dysplasia, both arthroscopy and periacetabularosteotomy (PAO) improve PROs when selection is phenotype-guided; PAO trends toward lower total hip arthroplasty (THA) conversion when undercoverage is the primary driver. Early postoperative circumduction is associated with lower rates of adhesion-related reoperation. Return-to-sport (RTS) decisions are criteria-based rather than time-based across successful programs.  \nConclusion: A seal-first, close-second strategy, situated within a stability continuum, underpins contemporary care. Standardized definitions, objective laxity metrics, multicenter registries, and microinstability-specific rehabilitation/RTS batteries are needed torefine indications and improve durability; evidence specific to labral augmentation in microinstability remains limited.  \nClinical Relevance: Precise phenotyping and capsular stewardship reduce the risk of revision hip arthroscopy and conversion to total hip arthroplasty, inform sport-specific counseling, and align with joint-preservation goals in young, active patients.  \nLevel of Evidence: V (Narrative Review) .  \nPlain Language Summary: Hip microinstability refers to the hip being slightly too loose to maintain the ball of the joint centered during everyday movement or sports. It can cause pain in the front or side of the hip, feelings of the hip giving way, and a clicking sensation. It is more common in athletes and in people with mild undercoverage of the hip socket (sometimes referred to as borderline dysplasia), generalized joint looseness, or differences in the twist of the thigh or pelvis.
