There are numerous subjective rating scales available to evaluate outcomes of total knee arthroplasty (TKA). Single Assessment Numerical Evaluation (SANE) score was developed to reduce the burden of patients or clinicians to evaluate patients' status by asking patients to simply rate the current status of their injured body part on a scale of 0-100. The purpose of this study is to investigate the correlation between SANE score and Lysholm score in patients who underwent primary TKA.
Forty-nine patients who underwent primary TKA participated. Patients who underwent bilateral TKA or revision TKA were excluded from this study. They were asked to respond to SANE and Lysholm scores. Regression analysis was used to evaluate the correlation between 2 scores. Bilateral isometric quadriceps strength and limb symmetry index were also measured and recorded.
There were a total of 49 patients in the study. The mean age of the subjects was 73.04 ± 6.63 years. The mean height and body weight were 153.37 ± 8.81 cm and 55.51 ± 8.61 kg, respectively. The mean scores for SNAE and Lysholm scores were 66.08 ± 16.77 and 71.0 ± 17.55, respectively. Pearson correlation coefficient between SANE and Lysholm scores was 0.38 ( = .003). Regression analysis showed statistically significant correlation between 2 scores with of 0.15 ( = .005). The average time from surgery was 16.02 weeks. The mean isometric quadriceps strength was 26.76 ± 11.30 kgf for the involved knee and 40.58 ± 11.55 kgf for the non-involved knee. The limb symmetry index was 66.10% ± 21.51%.
The results of the investigation showed that there was a statistically significant, however relatively weak, correlation between SANE score and Lysholm score. SANE score may serve as an alternative method to assess TKA patients' subjective post-operative outcomes to Lysholm score.
有许多主观评分量表可用于评估全膝关节置换术（TKA）的结果。单评估数值评定（SANE）评分的制定是为了减轻患者或临床医生评估患者状况的负担，方法是让患者简单地对其受伤身体部位的当前状况在0至100的量表上进行评分。本研究的目的是调查初次接受TKA的患者中SANE评分与Lysholm评分之间的相关性。
49例接受初次TKA的患者参与了研究。接受双侧TKA或翻修TKA的患者被排除在本研究之外。要求他们对SANE和Lysholm评分做出回应。采用回归分析来评估两个评分之间的相关性。还测量并记录了双侧等长股四头肌力量和肢体对称指数。
本研究共有49例患者。受试者的平均年龄为73.04±6.63岁。平均身高和体重分别为153.37±8.81厘米和55.51±8.61千克。SNAE评分和Lysholm评分的平均值分别为66.08±16.77和71.0±17.55。SANE评分与Lysholm评分之间的Pearson相关系数为0.38（P = .003）。回归分析显示两个评分之间存在统计学上的显著相关性，R²为0.15（P = .005）。手术平均时间为16.02周。患侧膝关节等长股四头肌平均力量为26.76±11.30千克力，健侧膝关节为40.58±11.55千克力。肢体对称指数为66.10%±21.51%。
调查结果表明，SANE评分与Lysholm评分之间存在统计学上的显著相关性，但相对较弱。SANE评分可作为一种替代方法，用于评估TKA患者术后的主观结果，以补充Lysholm评分。
