Orthopaedic patients with poor nutritional status are at an increased risk of postoperative complications, such as infection and wound healing. Nasal colonization with Staphylococcus aureus, especially with methicillin-resistant Staphylococcus aureus, has been shown to be a risk factor for surgical-site infections. We examined the incidence of nutritional depletion in our arthroplasty population and its correlation with Staphylococcus aureus colonization. We conducted a retrospective review of prospectively collected data of our arthroplasty patient population. Patients with known Staphylococcus aureus colonization or surgical-site infection were compared with a random cohort of patients. Patient demographics, preoperative nasal culture, and two nutritional screening scores were collected. Six hundred and fifty-two patients underwent arthroplasty and completed preoperative nasal cultures and nutritional assessment. A high percentage (27%) of our patients demonstrated some level of nutritional depletion prior to joint replacement. Overall nutritional scores were not significantly associated with surgery-type, preoperative nasal culture, or surgical- site infection in our patient population.
营养状况不佳的骨科患者术后出现并发症（如感染和伤口愈合问题）的风险会增加。已证实，金黄色葡萄球菌在鼻腔定植，尤其是耐甲氧西林金黄色葡萄球菌定植，是手术部位感染的一个风险因素。我们研究了关节置换患者群体中营养耗竭的发生率及其与金黄色葡萄球菌定植的相关性。我们对前瞻性收集的关节置换患者群体数据进行了回顾性分析。将已知有金黄色葡萄球菌定植或手术部位感染的患者与随机抽取的患者队列进行比较。收集了患者的人口统计学资料、术前鼻腔培养结果以及两项营养筛查评分。652例患者接受了关节置换手术，并完成了术前鼻腔培养和营养评估。我们的患者中有很大比例（27%）在关节置换术前就表现出一定程度的营养耗竭。在我们的患者群体中，总体营养评分与手术类型、术前鼻腔培养结果或手术部位感染并无显著关联。
