Radiographic evaluation and pain symptomatology of the knee in severely obese individuals – controlled transversal study

Abstract

ObjectiveTo evaluate the prevalence of pain and radiographic degenerative arthritis in a group of severe obese patients (body mass index [BMI] > 35).Methods41 patients with an indication of bariatric surgery were studied. The group of severely obese patients was subdivided into two subgroups: those with BMI < 50 and those with BMI > 50 (n = 14). They were compared to control group (n = 39). The following parameters were analyzed and correlated: radiographic arthritis by Kellgren-Lawrence's classification, tibiofemoral axis, gender, age, and knee pain (visual analog scale [VAS]). The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to evaluate in 21 severe obese patients and IN 19 controls.ResultsA higher incidence of knee pain was observed in the severely obese group when compared with the control group (p < 0.0001, odds ratio: 2.96). In the severely obese group, increasing levels of pain with aging were observed (p = 0.047). A positive correlation was observed between the incidence of radiographic arthritis and increasing age in the severely obese (p = 0.001) and control (p = 0.037) groups. The WOMAC index results were worse in the severely obese group when compared with the control group (p = 0.001, odds ratio: 18.2).ConclusionA higher incidence of knee pain was observed in the severely obese group when compared with the control group. In the severely obese group, there increasing levels of pain with aging. A positive relation between the incidence of arthritis and increasing age was observed in the severely obese and control groups. The WOMAC index results were worse in the severely obese group.

Avaliação funcional e de sintomatologia dolorosa do pé e tornozelo em indivíduos com obesidade grave – Estudo controlado transversal

“…2 Population studies have shown that obesity is an independent risk factor for knee pain and arthrosis. [3][4][5] In obese patients, feet pain incidence has been less studied in the literature than obesity-related knee pain. [3][4][5] Obesity results in feet pain and biomechanical changes secondary to flat foot deformity, plantar fat alterations, decreased muscle strength and gait pattern abnormalities.…”

[3][4][5] Obesity results in feet pain and biomechanical changes secondary to flat foot deformity, plantar fat alterations, decreased muscle strength and gait pattern abnormalities. 6 This process leads to loss of balance and risk of falling, interfering with the mobility of these individuals.…”

“…2 Estudos populacionais demonstraram que a obesidade é fator de risco independente para a manifestação de dor e artrose de joelho. [3][4][5] A prevalência de dor comprometendo os pés de indivíduos obesos foi menos estudada na literatura do que as alterações dolorosas em joelhos relacionadas à obesidade. [3][4][5] A obesidade ocasionaria dor e alterações biomecânicas no pé secundariamente à deformidade em pé plano, alterações na gordura plantar, diminuição da força muscular e modificações no padrão da marcha.…”
