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.
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.
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).
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.
在全膝关节置换术（TKA）中，选择正确的植入物尺寸很重要。关于血友病膝关节模板的准确性数据不足。我们的目的是测试 2D 数字模板在血友病性膝关节病变（HA）TKA 中的准确性。
筛选了 2011 年 1 月至 2022 年 1 月期间接受 HA 的 TKA。通过使用相同的植入物类型进行一对一匹配，创建了 OA 组作为对照组。在 HA 中测量了观察者内和观察者间的相关性，然后在四个评估（股骨 AP、股骨外侧、胫骨 AP、胫骨外侧）中研究了模板和植入物尺寸之间的相关性，然后与 OA 组进行比较。每组包括 58 个膝关节。
在 HA 中，观察者内相关性方面，股骨 AP [.93（.73-.98）]、股骨外侧 [.98（.91-.99）]和胫骨 AP 模板具有极好的相关性。在 HA 中，观察者间相关性方面，股骨外侧 [.93（.74-.98）]和胫骨 AP 模板具有极好的相关性 [.90（.65-.97）]。在 HA 中，模板和应用尺寸的相关性方面；胫骨 AP、胫骨外侧和股骨外侧模板具有良好的相关性 [.81（.70-.89）、.86（.77-.91）、.79（.67-.87）]，而股骨 AP 模板显示出中度相关性 [.67（.50-.79）]。比较 HA 和 OA，股骨 AP、股骨外侧、胫骨 AP 和胫骨外侧模板的相关性水平没有差异（p=0.056，p=0.781，p=0.761，p=0.083）。
尽管 2D 数字模板在 HA 和 OA 中显示出相当的相关性，但模板在 HA 中的临床适用性在当前状态下似乎受到限制。
