Hip osteoarthritis (OA) in athletes is important to acknowledge, with early hip OA associated with elite-level high joint impact sports, such as football, ice hockey and handball.1 Current management of hip OA is largely reactive (when OA disease is established and irreversible). Identifying athletes at risk of, or with early-stage hip OA, may improve treatment success and reduce disease burden. Clinicians and researchers need to understand the natural history of OA in active populations, risk factors for early hip OA and whether OA in athletes can be prevented. In this editorial, focussing on elite athletes, we aim to describe the natural history of hip OA, consider the role of primary cam morphology in hip OA development and provide clinical and research recommendations for the prevention of hip OA. Understanding the natural history of hip OA across the lifespan (figure 1), could empower clinicians and athletes/patients to prioritise appropriate evidence-based interventions (eg, education, clinician-led incremental exercise rehabilitation or surgery) for better hip health: 1. Adolescence : Changes in articular cartilage composition—a biomarker of early-stage OA—are evident in elite adolescent football players, possibly affecting its tolerance to high joint loads and increasing susceptibility to pathological change.2 This concept is supported by a recent longitudinal study of adolescent athletes where cartilage damage increased over 24 months.3 Primary cam morphology develops due to load-related femoral capital growth plate changes during maturation—from …

预防运动员髋骨关节炎：这真的是一项不可能完成的任务吗？

必须承认运动员的髋部骨关节炎 (OA)，早期髋部 OA 与精英级别的高关节冲击运动相关，例如足球、冰球和手球。1 目前髋部 OA 的治疗很大程度上是反应性的（当 OA 疾病确立时）并且不可逆转）。识别有髋关节骨关节炎风险或患有早期髋关节骨关节炎的运动员可能会提高治疗成功率并减轻疾病负担。临床医生和研究人员需要了解活跃人群中 OA 的自然史、早期髋关节 OA 的危险因素以及运动员中的 OA 是否可以预防。在这篇社论中，我们重点关注优秀运动员，旨在描述髋部 OA 的自然史，考虑初级凸轮形态在髋部 OA 发展中的作用，并为预防髋部 OA 提供临床和研究建议。了解髋关节 OA 在整个生命周期的自然史（图 1），可以帮助临床医生和运动员/患者优先考虑适当的循证干预措施（例如教育、临床医生主导的增量运动康复或手术），以改善髋关节健康：1.青春期：关节软骨成分的变化（早期 OA 的生物标志物）在青少年精英足球运动员中很明显，可能会影响其对高关节负荷的耐受性并增加对病理变化的敏感性。2 这一概念得到了最近一项纵向研究的支持。青少年运动员的软骨损伤在 24 个月内增加。3 由于成熟过程中与负荷相关的股骨头生长板变化，初级凸轮形态发生变化——从……
