“…Previous studies also found that the comparison of the raw impedance data between the affected limb vs. the unaffected limb was valid and correlated to volume [ 33 , 36 , 38 , 39 , 40 ]. The values observed in this study were within the range observed in previous studies that addressed the evaluation of upper arm lymphedema [ 38 ] or lower limb post-traumatic swelling [ 37 , 39 ]. Although post-surgical swelling has a less homogeneous composition than lymphedema, the evaluation of ECF appears to be of comparable validity for both conditions.…”

BackgroundThe evaluation of swelling is important for the outcome of total knee arthroplasty (TKA) surgery. The circumference or volume measurements are applicable at the bedside of the patient but are altered by muscular atrophy and the post-surgical dressing. Bioimpedance spectroscopy might overcome these limitations; however, it should be validated. This study aimed to explore the validity, the reliability and the responsiveness of bioimpedance spectroscopy for measuring swelling after TKA.MethodsThe degree of swelling in 25 patients undergoing TKA surgery was measured using bioimpedance spectroscopy (BIS R0), knee circumference and limb volume. The measurements were performed on D-1 (day before surgery), D + 2 (2 days after surgery) and D + 8 (8 days after surgery). The BIS R0 measurements were repeated twice, alternating between two evaluators. The percentage of the difference between the limbs was calculated for BIS R0, circumference and volume. The intra- and inter-observer intraclass correlation coefficients (ICCs), limits of agreement (LOA), effect size (Cohen’s d), correlations between the methods and diagnostic sensitivity were calculated.ResultsBIS R0, circumference and volume detected swelling < 3.5% at D-1. The swelling at D2 and D8 was greater with BIS R0 [mean (SD) 29.9% (±9.8) and 38.27 (±7.8)] than with volume [14.7 (±9.5) and 14.9 (±8.2)] and circumference [11.1 (±5.7) and 11.7 (±4.1)].The BIS R0 intra- and inter-evaluator ICCs ranged from 0.89 to 0.99, whereas the LOA were < 5.2%. The BIS R0 correlation was 0.73 with volume and 0.75 with circumference. The BIS R0 Cohen’s d was 3.32 for the D-1–D2 evolution. The diagnostic sensitivity was 83% D2 and 96% at D8.ConclusionBioimpedance is a valid method for the evaluation of swelling following TKA. BIS R0 also demonstrated excellent intra- and inter- evaluator reliability. The diagnostic sensitivity and responsiveness is superior to that of concurrent methods. BIS R0 is an efficient method for post-surgical follow up at the bedside of the patient. The measurement of BIS R0 is a straightforward, valid, reliable and responsive method for lower limb swelling following TKA surgery that could be used in clinics and research.Trial registrationClinicalTrials.gov Identifier: NCT00627770.

“…As for the evidence of BIS, it was demonstrated that BIS measurement for ankle swelling in subjects with ankle fracture correlated with volume measured by water displacement (r = −0.92, p = 0.001) better than single circumferential measurement (r = 0.81, p < 0.01). 23 In the context of TKA, Pichonnaz et al (2015) 24 reported a good correlation between BIS R0 with lower limb volume calculated by frustum model (r = 0.73) and BIS intra- and inter-evaluator ICCs ranging from 0.89 to 0.99. Yet, the correlation of bioimpedance to knee effusion and muscle volume has not been investigated.…”

“…On the other hand, the low capacitive effect of the cell membrane when the current at infinite frequency allows current to pass through both the intracellular and extracellular compartments and the impedance measured (the Ri variable) reflects the total fluid volume. 23 As post-surgical swelling is confined to the extracellular space, R0 could thus be considered as a potential indirect estimator of post-surgical swelling without the need to compensate for the metallic implant interference with measurement. 24 During a bioimpedance spectroscopy (BIS) measurement, the R values are predicted using a Cole–Cole plot without the need of administering current at zero frequency or extremely high frequency.…”

Background 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. Methods 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. Results 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. Conclusion Bioimpedance spectroscopy and 3D scanning technology can be the future tools for clinically measurement of knee swelling after total knee arthroplasty.
