Several randomized trials have demonstrated the lack of effect of arthroscopic lavage as treatment for knee osteoarthritis (OA). These results have in turn resulted in a change in Swedish guidelines and reimbursement. We aimed to investigate the use of knee arthroscopies in Sweden between 2002 and 2016. Patient demographics, regional differences, and the magnitude of patients with knee OA undergoing knee arthroscopy were also analyzed.
Trends in knee arthroscopy were investigated using the Swedish Hospital Discharge Register (SHDR) to conduct a nationwide register-based study including all adults (>18 years of age) undergoing any knee arthroscopy between 2002 and 2016.
The total number of knee arthroscopies performed during the studied period was 241,055. The annual surgery rate declined in all age groups, for males and females as well as patients with knee OA. The incidence dropped from 247 to 155 per 105 inhabitants. Over 50% of arthroscopies were performed in metropolitan regions.
We showed a dramatic decline in knee arthroscopy. There is variability in the surgery rate between males and females and among the regions of Sweden.
几项随机试验表明，关节镜灌洗术对膝骨关节炎（OA）的治疗无效。这些结果反过来又导致了瑞典指南和报销政策的改变。我们旨在调查 2002 年至 2016 年间瑞典膝关节镜检查的使用情况。还分析了患者人口统计学、区域差异以及接受膝关节镜检查的膝骨关节炎患者的数量。
使用瑞典住院患者登记系统（SHDR）调查膝关节镜检查的趋势，进行一项全国性的基于登记的研究，包括 2002 年至 2016 年间接受任何膝关节镜检查的所有成年人（>18 岁）。
研究期间共进行了 241055 例膝关节镜检查。所有年龄组、男性和女性以及膝骨关节炎患者的年手术率均下降。发病率从每 105 名居民 247 例降至 155 例。超过 50%的膝关节镜检查在大都市区进行。
我们发现膝关节镜检查数量急剧下降。手术率在男性和女性以及瑞典各地区之间存在差异。
