With great interest, we have read the paper by Kumar et al. [1]. In this paper, the authors conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing cemented and cementless hemiarthroplasty in the treatment of femoral neck fractures. The authors excluded RCTs which studied outdated and rarely used stems (e.g., Austin Moore and Thompson). We agree with the authors that these stems are less relevant today and might have influenced the results of previously published meta-analyses. Therefore, we conducted a comparable meta-analysis with currently relevant stems in 2017 [2].

Shortly after our publication, a relevant RCT was published by Moerman et al. [3]. This publication was identified by the systematic literature search conducted by Kumar et al., who included no other additional RCTs in the pooling of results. Furthermore, they did not include two RCTs [4, 5], which were included in our meta-analysis. Talsnes et al. [4] compared the cementless...
