摘要
背景:尽管部分膝关节置换术(PKR)具有公认的优势，但其应用仍然有限。我们调查了医院膝关节置换术(KA)容积和总KA供应商经常使用的PKR的可用性对PKR在医院使用的影响。方法:2007年至2016年，荷兰关节置换术登记册(LROI)共登记了190,204例全膝关节置换术(TKR)和18,134例pkr。对于每家医院，我们将年度绝对KA量(TKR+PKR)确定为四分位数(292次膝关节置换/年)，并确定TKR供应商是否提供常用的PKR。医院被分为常规PKR使用者(≥13 PKR /年)和偶尔/非PKR使用者(结果:在最低容量组中，约15%的医院使用PKR，而在最高容量组中，这一比例为75%。如果TKR供应商也提供经常使用的PKR，则更有可能执行PKR，特别是在小容量医院。结论:医院的KA总量和经常使用的PKR的可用性似乎影响PKR的使用。
Nationwide partial knee replacement uptake is influenced by volume and supplier--A Dutch arthroplasty register study.
Background: Despite the established advantages of partial knee replacements (PKR), their usage remains limited. We investigated the effect of hospital knee arthroplasty (KA) volume and the availability of a frequently used PKR by the total KA supplier on the use of PKRs in a hospital.
Methods: A total of 190,204 total knee replacements (TKR) and 18,134 PKRs were identified in the Dutch Arthroplasty Register (LROI) from 2007 to 2016. For each hospital we determined the annual absolute KA volume (TKR+PKR) into quartiles (<103, 103-197, 197-292, >292 knee replacements/year), and determined whether the TKR supplier provided a frequently used PKR. Hospitals were divided in routine PKR users (≥13 PKRs/year) or occasional/non PKR users (<13 PKRs/year). Based on these parameters, the effect of total KA volume and supplier on PKR usage was investigated, using chi-square tests. Logistic regression analysis was performed to evaluate the influence of the combination of these factors.
Results: In the lowest volume group, around 15% of the hospitals used PKRs, compared to 75% in the highest volume group. Having a TKR supplier that also provides a frequently used PKR resulted in a higher likelihood of performing PKR, especially in low volume hospitals.
Conclusions: Hospitals' total KA volume and the availability of a frequently used PKR appear to influence the use of PKR.
期刊介绍：
Journal of Orthopaedic Surgery is an open access peer-reviewed journal publishing original reviews and research articles on all aspects of orthopaedic surgery. It is the official journal of the Asia Pacific Orthopaedic Association.
The journal welcomes and will publish materials of a diverse nature, from basic science research to clinical trials and surgical techniques. The journal encourages contributions from all parts of the world, but special emphasis is given to research of particular relevance to the Asia Pacific region.
