The Use of Stems for Morbid Obesity in Total Knee Arthroplasty

J Knee Surg DOI: 10.1055/s-0039-1681078Morbidly obese patients undergoing total knee arthroplasty have worse functional outcomes and implant survival, and increased revision rates compared with nonobese patients. In addition to increased medical comorbidities and difficult exposure, increased stress on the tibial implant and altered kinematics of knee motion contribute to aseptic loosening and medial collapse. Increased implant fixation, including use of a stemmed tibial implant, may be a way to help avoid these complications. While there is limited data on tibial stems in the morbidly obese patients specifically, cemented stemmed tibial implants should be strongly considered in these patients, especially if bone quality is poor. The initial increased cost of a stemmed implant can be justified in this high-risk patient population to minimize the risk of costly revisions related to compromised tibia component fixation.

CONCLUSIONS: Although DM was the disease most commonly associated with PUs and NAs, chronic hyperglycemia may not have been the major underlying risk factor. The major risk covariates are sensation loss from polyneuropathy, old age, obesity, repetitive foot injury, and inadequate foot care or treatment. Physicians and other healthcare providers can help by identifying patients at risk and instituting measures such as adequate foot care to decrease these risks.

Publication date: Available online 19 March 2019Source: Colloids and Surfaces A: Physicochemical and Engineering AspectsAuthor(s): Soomin Han, Younghun KimAbstractObesity is one of the most serious health problems, and liposuction among the treatment strategies is the most common and popular regimen, but it induces various undesired side-effects. Here, we synthesized a polypyrrole (PPy)-coated hollow gold nanoshell (HAuNS@PPy) that minimized these side-effects of liposuction (pain, bleeding, infection, and long recovery times). To improve biocompatibility and photothermal conversion efficiency, PPy was coated on the surfac...

ConclusionOur findings revealed that women with low MUAC were more likely to have an inadequate gestational weight gain rate during pregnancy whereas higher MUAC was associated with an excessive gestational weight gain rate. MUAC may be a useful indicator of nutritional status associated with GWG. Routine measurement of MUAC in pregnant women may help health professionals, particularly in middle-income countries, to counsel women about gestational weight gain.

AbstractPurposeTo evaluate the relationship between obesity and insulin resistance among women with polycystic ovary syndrome (PCOS) using a gold standard test.MethodsA retrospective database analysis of 75 women with PCOS and 118 normal controls who underwent a modification of the insulin suppression test. The relationships between body mass index (BMI) and steady-state plasma glucose (SSPG) levels were investigated.ResultsMean SSPG score for PCOS subjects was statistically similar than that of the controls at all BMI groupings. Only when PCOS subjects reached a BMI of ≥30 kg/m2 that the PCOS subjects had higher...

This study reports single-surgeon experience with extended gastrectomy including en-bloc resection of adjacent organs/structures for T4b stage gastric adenocarcinoma. Time-related changes in patient selection criteria and outcomes were also analyzed.MethodsAll consecutive gastrectomies for adenocarcinoma performed between May 2004 and December 2017 were extracted from prospectively collected database to study surgical and oncologic results. Time-related changes in outcomes were examined according to three time periods.ResultsFive hundred eighty-seven gastrectomies were performed throughout the study period including 87 (14...

Hypothalamic obesity (HO) frequently occurs following damage to the medial hypothalamic region, encompassing the arcuate nucleus, the paraventricular nucleus, the ventromedial nucleus, the dorsomedial nucleus, and the dorsal hypothalamic area, which are critically involved in the regulation of satiety and energy balance through neural and humoral connections. HO is most commonly described in the context of craniopharyngioma and its treatment, but it can also occur following other suprasellar tumors, radiation, trauma, or a surgical insult to the hypothalamus. A constellation of loss of satiety and a reduction of the metabo...
