Abstract

Introduction

In total knee arthroplasty (TKA), choosing the correct implant size is important. There is lack of data on accuracy of templating on haemophilic knees. Our aim was to test the accuracy of 2D digital templating for TKA on haemophilic arthropathy (HA) of knee.

Materials and Methods

TKAs performed on HA between January 2011 and January 2022 were screened. Osteoarthritis (OA) group was created as control group by a one-to-one matching regarding type of implant used. Intra- and interobserver correlations were measured in HA, then correlation between templated and implanted sizes was investigated in four assessments (femur AP, femur lateral, tibia AP, tibia lateral), then compared with OA group. Fifty-eight knees in each group included.

Results

Regarding intraobserver correlation in HA, there was excellent correlation for femur AP [.93 (.73–.98)], femur lateral [.98 (.91–.99)], and tibia AP (1.0) templating. Regarding interobserver correlation in HA, excellent correlation was observed for femur lateral [.93 (.74–.98)] and tibia AP templating [.90 (.65–.97)]. Regarding correlation of templated and applied sizes in HA; tibia AP, tibia lateral and femur lateral templating showed good correlation [.81 (.70–.89), .86 (.77–.91), .79 (.67–.87) while femur AP templating showed moderate correlation [.67 (.50–.79)]. Comparing HA and OA, there was no difference in correlation levels regarding femur AP, femur lateral, tibia AP and tibia lateral templating (p = .056, p = .781, p = .761, p = .083, respectively).

Conclusion

Although 2D digital templating shows comparable correlation in HA and OA, clinical applicability of templating on HA appears to be limited in its current state.

血友病膝关节全膝关节置换术数字模板的准确性和临床作用

导言：在全膝关节置换术（TKA）中，选择正确的植入物尺寸非常重要。目前还缺乏有关嗜血膝关节模板制作准确性的数据。我们的目的是测试二维数字模板对嗜血细胞性膝关节病（HA）的 TKA 的准确性。骨关节炎（OA）组作为对照组，在所用植入物类型上进行一对一匹配。在HA组中测量观察者内部和观察者之间的相关性，然后在四项评估（股骨AP、股骨侧、胫骨AP、胫骨侧）中调查模板尺寸和植入尺寸之间的相关性，然后与OA组进行比较。结果关于HA的观察者内相关性，股骨AP[.93（.73-.98）]、股骨侧[.98（.91-.99）]和胫骨AP（1.0）模板的相关性极佳。在医管局的观察者间相关性方面，股骨外侧[.93（.74-.98）]和胫骨AP模板[.90（.65-.97）]的相关性极佳。关于HA中模板和应用尺寸的相关性，胫骨AP、胫骨外侧和股骨外侧模板显示出良好的相关性[.81（.70-.89）、.86（.77-.91）、.79（.67-.87）]，而股骨AP模板显示出中等相关性[.67（.50-.79）]。结论虽然二维数字模板在HA和OA中显示出相似的相关性，但目前模板在HA中的临床应用似乎还很有限。
