Total knee arthroplasty is a commonly performed elective orthopaedic surgery. Patients may endure substantial knee swelling following surgery, which are attributable to both effusion and edema. Studies have been aiming to identify an accurate and reliable method to quantify post-operative knee swelling to aid monitoring progress and treatment. The aim of this article was to review the means of clinically applicable measurements for knee swelling post TKA.
The medical literature was searched using PubMed to search for articles published using the terms knee edema, effusion, swelling, knee arthroplasty, knee replacement, total knee arthroplasty, total knee replacement, TKA, TKR. Year of publication was not restricted. Only English language publications were included. Only full-text published articles from peer-reviewed journals were eligible for inclusion. The knee swelling measurement methods used in post TKA were reviewed.
Advancement in bioimpedance spectroscopy and handheld 3D scanning technology allows quick and precise quantification of knee swelling volume that the traditional clinical circumferential measurement and volumetric measurement lack. Handheld 3D scanning is also a potential tool to estimate the change of knee effusion volume and muscular volume after the surgery. Magnetic resonance imaging is accurate in effusion measurement but also the most time and resource demanding method.
Bioimpedance spectroscopy and 3D scanning technology can be the future tools for clinically measurement of knee swelling after total knee arthroplasty.
全膝关节置换术是一种常见的择期矫形手术。患者术后可能会经历大量的膝关节肿胀，这归因于渗出液和水肿。研究旨在寻找一种准确可靠的方法来量化术后膝关节肿胀，以帮助监测进展和治疗。本文旨在回顾 TKA 后膝关节肿胀的临床适用测量方法。
使用 PubMed 搜索医学文献，使用“膝关节水肿”、“渗出液”、“肿胀”、“膝关节置换术”、“膝关节置换”、“全膝关节置换术”、“全膝关节置换”、“TKA”、“TKR”等术语搜索文章。没有限制发表年份。仅包括使用英语发表的出版物。只有同行评议期刊的全文出版文章才有资格入选。回顾了 TKA 后用于膝关节肿胀测量的方法。
生物阻抗光谱和手持式 3D 扫描技术的进步允许快速准确地量化膝关节肿胀体积，而传统的临床周径测量和体积测量方法则缺乏这一功能。手持式 3D 扫描也是估计手术后膝关节积液量和肌肉量变化的潜在工具。磁共振成像在测量积液方面非常准确，但也是最耗时和最耗费资源的方法。
生物阻抗光谱和 3D 扫描技术可能是全膝关节置换术后膝关节肿胀临床测量的未来工具。
