There are 12 signs of the zodiac, each attributed with its own specific personality traits, desires and attitudes. The aim of the study was to evaluate the effect of zodiac sign on patient-reported outcome measures (PROMS) following primary total knee arthroplasty (TKA).
Patients undergoing primary TKA during a 2-year period (January 2019 to December 2020) were identified retrospectively. Patient demographics, Oxford Knee Score (OKS), EuroQol 5-dimension (EQ-5D) (baseline, 1 and 2 years) and patient satisfaction scores (1 and 2 years) were collected. Each patient's zodiac sign was assigned from their date of birth.
There were 509 patients (228 males [44.8%] and 281 females [55.2%]) with a mean age of 70.9 years and a mean BMI of 30.3. There were no significant differences in gender (p=0.712), age (p=0.088), BMI (p=0.660), or pre-operative OKS (p=0.539). Aries and Gemini (0.366) had the worst and Pisces the best (0.595) pre-operative EQ-5D scores (p=0.038). When adjusting for confounding, Aries (p=0.031) had a greater improvement in EQ-5D at 1 year, although this was not maintained at 2 years. When adjusting for confounding, Pisceans had significantly less of an improvement in OKS at both 1 (p=0.022) and 2 years (p=0.042) and also had a significantly lower risk of satisfaction at 2 years (odds ratio 0.41, p=0.043).
Zodiac sign was associated with outcome following TKA. Pisceans had the best pre-operative EQ-5D scores, but the least improvement in the post-operative joint specific score (OKS) and were less likely to be satisfied, despite achieving an equal improvement in their health-related quality of life (EQ-5D). Aries started with the lowest pre-operative EQ-5D scores but achieved the best scores at 1 year. Our study shows that an individual's zodiac sign may serve as a useful predictive factor for functional outcomes and satisfaction following TKA. However, our findings are the result of multiple testing in a large dataset following a data trawl, and correlation does not necessarily equal causation even in a real-world registry.
有 12 个星座，每个星座都有其独特的个性特征、欲望和态度。本研究旨在评估星座对初次全膝关节置换术（TKA）后患者报告的结果测量（PROMs）的影响。
回顾性地确定了在 2 年期间（2019 年 1 月至 2020 年 12 月）接受初次 TKA 的患者。收集了患者的人口统计学资料、牛津膝关节评分（OKS）、欧洲五维健康量表（EQ-5D）（基线、1 年和 2 年）和患者满意度评分（1 年和 2 年）。从患者的出生日期为每位患者分配星座。
共有 509 名患者（228 名男性[44.8%]和 281 名女性[55.2%]），平均年龄为 70.9 岁，平均 BMI 为 30.3。在性别（p=0.712）、年龄（p=0.088）、BMI（p=0.660）或术前 OKS（p=0.539）方面无显著差异。白羊座和双子座（0.366）的术前 EQ-5D 评分最差，而双鱼座（0.595）最好（p=0.038）。在调整混杂因素后，白羊座（p=0.031）在 1 年时 EQ-5D 的改善更大，但在 2 年时没有维持。在调整混杂因素后，双鱼座在 1 年（p=0.022）和 2 年（p=0.042）时 OKS 的改善明显较少，并且在 2 年时满意度的风险明显较低（优势比 0.41，p=0.043）。
星座与 TKA 后的结果相关。双鱼座术前 EQ-5D 评分最高，但术后关节特异性评分（OKS）改善最小，且术后满意度较低，尽管他们的健康相关生活质量（EQ-5D）也有同等改善。白羊座术前 EQ-5D 评分最低，但在 1 年时得分最高。我们的研究表明，一个人的星座可能是 TKA 后功能结果和满意度的有用预测因素。然而，我们的发现是在大数据集进行数据挖掘后进行多次测试的结果，即使在真实世界的登记处，相关性也不一定等同于因果关系。
