Gold PA, Garbarino LJ, Anis HK, et al. - This research seeks to correlate the impact of catheterization treatments onpostoperative ambulation distances, deep vein thromboses (DVTs), and pulmonary emboli (PEs) following total knee arthroplasty (TKA). Researchers examined a sum of 9,123 prospectively collected primary TKA individuals based on postoperative catheter status. They obtained patient demographics, Charlson Comorbidity Indices, body mass indices, DVT prophylaxes, first ambulation distances, DVTs, and PEs at approximately mean 12 months of follow-up. Univariate and multivariate analyses were conducted with independent t-tests and multiple linear regression models in order to correlate catheterization procedures. The outcomes of this research displayed that that the use of an indwelling catheter for treatment of urinary retention significantly reduced TKA patient ambulation distance and subsequently increased the risk for DVTs. It is suggested that this information is beneficial as we would recommend the treatment with intermittent catheterization rather than indwelling catheters to reduce the risk of immobilization and postoperative DVTs.
