Quelle est la prévalence de l'arthrose et des pathologies intra-articulaires de la hanche chez les athlètes actifs souffrant de douleurs à la hanche et à l'aine, comparées à ceux qui n'en ont pas ? Une revue systématique et une méta-analyse



INTRODUCTION

Les douleurs à la hanche et à l'aine sont courantes chez les athlètes, en particulier ceux participant aux activités tel que le football, le hockey sur glace et la danse. La douleur à la hanche et à l'aine constitue jusqu'à 18% de toutes les blessures entraînant une perte de temps dans le football professionnel. En outre, dans le football, 59% des hommes et 45% des femmes vont souffrir de douleurs à l'aine ou de blessures durant une saison de compétition. De nombreux athlètes connaîtront des symptômes de longue durée, un footballeur élite sur trois souffrant de douleurs à la hanche et à l'aine présentant des symptômes persistants depuis plus de 6 semaines. La chronicité des symptômes est associée à de plus grandes difficultés dans les activités de la vie quotidienne, à une baisse de la qualité de la vie et à une altération des performances sportives.
 
La douleur à l'aine liée à la hanche chez les athlètes résulte souvent du syndrome de conflit fémoroacétabulaire (type cam ou pince) et de lésion labrales. Au fil du temps, la morphologie en cam peut entraîner des affections intra-articulaires de la hanche, y compris l'arthrose de la hanche. La morphologie en cam est associée à une pathologie intra-articulaire, notamment des déchirures labrales chez les personnes souffrant ou non de douleur [25–27], et multiplie par dix le risque de développer une arthrose chez les adultes plus âgés.
 
Des études sur la prévalence d'affections intra-articulaires de la hanche, y compris la morphologie osseuse, les déchirures labrales et les défauts du cartilage chez les athlètes, n'ont pas décrit toutes les pathologies intra-articulaires fréquemment rapportées. De plus, La prévalence de l'arthrose de la hanche chez les athlètes à la retraite est connue, mais la prévalence chez les athlètes pratiquant actuellement un sport ne l'est pas.

OBJECTIF 

Le but de cette revue était de déterminer la prévalence de pathologies intra-articulaires de la hanche telles que les déchirures labrales, les défauts du cartilage, les déchirures ligamenteuses, les lésions de la moelle osseuse, la synovite et l'arthrose de la hanche chez les athlètes avec et sans douleur à la hanche et à l'aine qui font actuellement du sport.

METHODE

Deux auteurs indépendants ont entrepris une recherche exhaustive à l'aide des bases de données OVID MEDLINE, Pub-Med, CINAHL, EMBASE, SPORTDiscus, SCOPUS et Cochrane.
 
Deux auteurs ont indépendamment extrait les données des 20 articles inclus.
 
Pour déterminer la prévalence des pathologies intra-articulaires de la hanche et / ou de l'arthrose, le nombre d'athlètes (cas) a été divisé par la population totale d'athlètes incluse dans l'article. Les auteurs ont utilisé le logiciel Comprehensive Meta-Analysis pour déterminer la prévalence globale et les intervalles de confiance à 95%. La prévalence des pathologies intra-articulaires de la hanche et de l'arthrose a été rapportée soit par personne, soit par hanche, selon la méthode utilisée dans l'article inclus.

RESULTAT
 
  • À la fin de la recherche dans la base de données, 847 articles ont été identifiés. L'élimination des doublons a laissé 470 articles à filtrer par titre et par résumé, et 69 articles en texte intégral dont l'éligibilité a été évaluée à l'aide des critères d'inclusion énumérés. Au total, six articles supplémentaires ont été récupérés et évalués pour inclusion après la fin de la recherche dans la liste de références et le suivi des citations. Cinquante-cinq articles ont été exclus, avec un total de 20 articles inclus dans l'analyse pour une analyse qualitative et quantitative.
Quelle est la prévalence de l'arthrose et des pathologies intra-articulaires de la hanche chez les athlètes actifs souffrant de douleurs à la hanche et à l'aine, comparées à ceux qui n'en ont pas ? Une revue systématique et une méta-analyse

  • Chez les athlètes asymptomatiques, des preuves limitées identifiaient une prévalence de déchirure labrale de 54% par personne et une preuve modérée de 33% par hanche. Chez les athlètes symptomatiques, une prévalence modérée de 20% de déchirure labrale par hanche a été constatée.
Quelle est la prévalence de l'arthrose et des pathologies intra-articulaires de la hanche chez les athlètes actifs souffrant de douleurs à la hanche et à l'aine, comparées à ceux qui n'en ont pas ? Une revue systématique et une méta-analyse

  • Des preuves modérées d'une prévalence de 10% par défaut de cartilage ont été rapportées chez des athlètes asymptomatiques. Chez les athlètes symptomatiques, la prévalence des défauts du cartilage était de 7 à 40%.
 
  • Chez les athlètes asymptomatiques, la prévalence de l'arthrose de la hanche était de 0 à 17%, contre 2% chez les athlètes symptomatiques.
Quelle est la prévalence de l'arthrose et des pathologies intra-articulaires de la hanche chez les athlètes actifs souffrant de douleurs à la hanche et à l'aine, comparées à ceux qui n'en ont pas ? Une revue systématique et une méta-analyse

CONCLUSION

Cette revue systématique met en évidence que des pathologies intra-articulaires de la hanche par imagerie définies sont observées chez les athlètes avec et sans douleur. Parmi les études incluses, les méthodes utilisées pour évaluer la présence de pathologies intra-articulaires de la hanche présentaient une hétérogénéité considérable.
 
Des pathologies intra-articulaires de la hanche sont observées chez les athlètes avec et sans douleur. Les déchirures labiales ont été identifiées chez un sportif sur deux sans douleur, soulignant ainsi une relation discordante potentielle entre les déchirures labrales et la douleur chez les athlètes. Des défauts cartilagineux, des lésions de la moelle osseuse, des hernies, une érosion de la hanche, une dégénérescence labrale et des déchirures ligamentaires ont été observés chez des athlètes symptomatiques et asymptomatiques. Une relation complexe existe entre les conditions structurelles de la hanche identifiées avec l'imagerie et la douleur chez les athlètes.
