Total knee arthroplasty (TKA) can improve pain, quality of life, and functional outcomes. Although uncommon, postoperative complications are extremely consequential and thus must be carefully tracked and communicated to patients to assist their decision-making before surgery. Identification of the risk factors for complications and readmissions after TKA, taking into account common causes, temporal trends, and risk variables that can be changed or left unmodified, will benefit this process.
To assess readmission rates, early complications and their causes after TKA at 30 days and 90 days post-surgery.
This was a prospective and retrospective study of 633 patients who underwent TKA at our hospital between January 1, 2017, and February 28, 2022. Of the 633 patients, 28 were not contactable, leaving 609 who met the inclusion criteria. Both inpatient and outpatient hospital records were retrieved, and observations were noted in the data collection forms.
Following TKA, the 30-day and 90-day readmission rates were determined to be 1.1% ( = 7) and 1.8% ( = 11), respectively. The unplanned visit rate at 30 days following TKA was 2.6% ( = 16) and at 90 days was 4.6% ( = 28). At 90 days, the unplanned readmission rate was 1.4% ( = 9). Reasons for readmissions included medical (27.2%, = 3) and surgical (72.7%, = 8). Unplanned readmissions and visits within 90 days of follow-up did not substantially differ by age group ( = 0.922), body mass index (BMI) ( = 0.633), unilateral bilateral TKA ( = 0.696), or patient comorbidity status (30-day = 0.171 and 90-day = 0.813). Reoperation rates after TKA were 0.66% ( = 4) at 30 days and 1.15% ( = 8) at 90 days. The average length of stay was 6.53 days.
In this study, there was a low readmission rate following TKA. There was no significant correlation between readmission rate and patient factors such as age, BMI, and co-morbidity status.
全膝关节置换术（TKA）可改善疼痛、生活质量和功能结局。尽管术后并发症并不常见，但后果极其严重，因此必须仔细跟踪并告知患者，以帮助他们在手术前做出决策。识别TKA术后并发症和再入院的风险因素，考虑常见原因、时间趋势以及可以改变或不改变的风险变量，将有助于这一过程。
评估TKA术后30天和90天的再入院率、早期并发症及其原因。
这是一项对2017年1月1日至2022年2月28日在我院接受TKA的633例患者进行的前瞻性和回顾性研究。在633例患者中，28例无法联系，剩下609例符合纳入标准。检索了住院和门诊病历，并在数据收集表中记录观察结果。
TKA术后，30天和90天的再入院率分别确定为1.1%（n = 7）和1.8%（n = 11）。TKA术后30天的非计划就诊率为2.6%（n = 16），90天为4.6%（n = 28）。90天时，非计划再入院率为1.4%（n = 9）。再入院原因包括医疗（27.2%，n = 3）和手术（72.7%，n = 8）。随访90天内的非计划再入院和就诊在年龄组（p = 0.922）、体重指数（BMI）（p = 0.633）、单侧 vs 双侧TKA（p = 0.696）或患者合并症状态（30天p = 0.171和90天p = 0.813）方面没有显著差异。TKA术后30天的再次手术率为0.66%（n = 4），90天为1.15%（n = 8）。平均住院时间为6.53天。
在本研究中，TKA术后再入院率较低。再入院率与年龄、BMI和合并症状态等患者因素之间没有显著相关性。
