New analyses fill an important evidence gap while we wait for trials In 2020, the National Institute for Health and Care Research commissioned the randomised RAPSODI trial, aiming to find the best type of joint replacement for the treatment of painful osteoarthritis of the shoulder. This trial commenced in 2022, but will not report its results until the spring of 2027 at the eaanatorliest.1 In a linked paper in The BMJ (doi:10.1136/bmj-2023-077939), Valsamis and colleagues leveraged routinely collected data from public and private hospitals in England, using modern epidemiological methods to provide faster high quality evidence to answer this important question.2 By combining data from the National Joint Registry and NHS Hospital Episode Statistics datasets, they harnessed one of the world’s largest and most comprehensive repositories of shoulder replacement information. Joint replacement is an effective treatment for pain and reduced function caused by osteoarthritis of the shoulder. The implant design can be anatomical, where the ball and socket are replaced (which has been the conventional treatment for many years); or reverse, where the orientation of the …

选择最佳的肩关节置换术

在我们等待试验的同时，新的分析填补了重要的证据空白 2020 年，美国国家健康与护理研究所委托开展随机 RAPSODI 试验，旨在寻找治疗肩部疼痛性骨关节炎的最佳关节置换术类型。该试验于 2022 年开始，但要到 2027 年春天才会报告结果。1 在《BMJ》的一篇链接论文中 (doi:10.1136/bmj-2023-077939)，Valsamis 和同事利用了从公众那里定期收集的数据和英格兰的私立医院，使用现代流行病学方法提供更快的高质量证据来回答这一重要问题。2通过结合国家联合登记处和 NHS 医院病例统计数据集的数据，他们利用了世界上最大、最全面的数据库之一肩部置换信息。关节置换术是治疗肩部骨关节炎引起的疼痛和功能下降的有效方法。种植体设计可以是解剖学的，其中球和窝被替换（这是多年来的传统治疗方法）；或相反，其中...的方向
