Abstract

Background

Thrombosis is a common postoperative complication after unicompartmental knee arthroplasty (UKA), and the ability to squat is an important functional outcome reflecting recovery of knee function. This study aimed to investigate the factors influencing postoperative thrombosis as well as the ability to squat within 1 year after UKA.

Methods

Data from UKA patients were retrospectively analyzed and grouped based on the occurrence of thrombosis (including deep vein thrombosis and superficial vein thrombosis) and the ability to squat within 1 year. Factors affecting thrombosis and squatting were compared and analyzed using multifactorial logistic regression.

Results

Univariate analysis revealed that age (P = 0.014), pre-operative haemoglobin (P = 0.044), and gender (P = 0.047) were associated with thrombosis, while multifactorial analysis found age (P = 0.024) as the key factor. Regarding squatting ability, univariate analysis identified age (P = 0.018), body weight (P = 0.001), BMI (P = 0.001), waist circumference (P < 0.001), pre-operative VAS score (P = 0.002), and family living conditions (P = 0.019) as influencing factors, with multifactorial analysis identifying waist circumference (P = 0.002) as a significant factor.

Conclusions

Older age increases the likelihood of thrombosis after UKA. Additionally, a larger waist circumference decreases the likelihood of squatting within 1 year after surgery.

背景血栓形成是单间室膝关节置换术（UKA）后常见的术后并发症，而下蹲能力是反映膝关节功能恢复的重要功能结果。本研究旨在探讨影响术后血栓形成以及单关节膝关节置换术后一年内下蹲能力的因素。方法回顾性分析单关节膝关节置换术患者的数据，并根据血栓形成（包括深静脉血栓形成和浅静脉血栓形成）和一年内下蹲能力进行分组。结果单因素分析显示，年龄（P = 0.014）、术前血红蛋白（P = 0.044）和性别（P = 0.047）与血栓形成有关，而多因素分析发现年龄（P = 0.024）是关键因素。关于下蹲能力，单变量分析发现年龄（P = 0.018）、体重（P = 0.001）、体重指数（BMI）（P = 0.001）、腰围（P < 0.001）、术前 VAS 评分（P = 0.002）和家庭生活条件（P = 0.019）是影响因素，多因素分析发现腰围（P = 0.002）是重要因素。结论年龄越大，UKA术后血栓形成的可能性就越大，此外，腰围越大，术后1年内下蹲的可能性就越小。
