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.
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.
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.
Hospitals' total KA volume and the availability of a frequently used PKR appear to influence the use of PKR.
尽管部分膝关节置换术（PKR）具有已确立的优势，但它们的使用仍然有限。我们研究了医院膝关节置换术（KA）量和总 KA 供应商提供的常用 PKR 的可用性对医院中 PKR 使用的影响。
在 2007 年至 2016 年期间，荷兰关节置换登记处（LROI）共确定了 190204 例全膝关节置换术（TKR）和 18134 例 PKR。对于每个医院，我们将每年的绝对 KA 量（TKR+PKR）分为四分位数（<103、103-197、197-292、>292 个膝关节置换/年），并确定 TKR 供应商是否提供了常用的 PKR。医院分为常规 PKR 用户（≥13 个 PKR/年）或偶尔/非 PKR 用户（<13 个 PKR/年）。基于这些参数，使用卡方检验研究了总 KA 量和供应商对 PKR 使用的影响。进行逻辑回归分析以评估这些因素组合的影响。
在最低容量组中，约有 15%的医院使用了 PKR，而在最高容量组中，这一比例为 75%。拥有同时提供常用 PKR 的 TKR 供应商会增加进行 PKR 的可能性，尤其是在低容量医院。
医院的总 KA 量和常用 PKR 的可用性似乎会影响 PKR 的使用。
