Abstract：
UNASSIGNED: This study aimed to evaluate the changing experiences of shoulder surgeons working in a district general hospital.
UNASSIGNED: A consecutive series of 395 shoulders (225 male, 170 female) over a 19-year period (2000-2019) with a minimum follow-up of 2 years were analyzed. Outcome measures were length of stay, operating time, satisfaction visual analog score (VAS), pain VAS, Oxford Shoulder Score (OSS), Constant-Murley score, range of movement, complications, and implant survival.
UNASSIGNED: The incidence of a diagnosis of osteoarthritis as the surgical indication increased over time. The number of cases by surgeon per year increased from three cases in 2,000 to a peak of 33 in 2011. Up to seven implant manufacturers were used. The incidence of hemiarthroplasties decreased, and more numerous reverse polarity and anatomic arthroplasties were performed (P<0.001). More glenoid and humeral components were cemented and more short-stem implants were used in later years (P<0.001). Length of stay was a median of 1 day with a trend towards daytime surgery in recent years. Patients were satisfied (VAS 8/10) and OSS improved by 8 points on average throughout the observation period.
UNASSIGNED: Despite frequent introductions of new implants, patient outcome, satisfaction, and complication rates remained good. There appears to be a need for large-scale, generalizable studies to understand why technological advancements leading to changes in implants do not influence clinical outcomes. Level of evidence: III.

摘要：
■本研究旨在评估在地区综合医院工作的肩部外科医生不断变化的经历。
■连续395个肩膀（225个男性，分析了170名女性），历时19年（2000-2019年），最少随访2年。结果衡量标准是停留时间，操作时间,满意度视觉模拟评分(VAS)，疼痛VAS,牛津肩评分（OSS），Constant-Murley得分,运动范围,并发症,和植入物存活。
■作为手术指征的骨关节炎的诊断发生率随时间增加。外科医生每年的病例数量从2,000例中的3例增加到2011年的33例峰值。使用了多达七个植入物制造商。半关节置换术的发生率下降，进行了更多的反极性和解剖关节置换术（P<0.001）。更多的关节盂和肱骨组件被骨水泥化，更多的短柄植入物在以后的几年中被使用（P<0.001）。住院时间的中位数为1天，近年来有白天手术的趋势。患者满意（VAS8/10），OSS在整个观察期间平均提高8分。
■尽管经常引入新的植入物，患者结果,满意,并发症发生率保持良好。似乎需要大规模，可推广的研究，以了解为什么导致植入物变化的技术进步不会影响临床结果。证据等级：III.
