The Impact of Weight Loss on Lomber and Knee Pain

Abstract

Objectives: When the risk factors of symptomatic osteoarthritis (OA) are evaluated, it has been shown

that increased body mass index, lower educational levels and social support, depressive mood are

associated with reporting more pain. The aim of this study was to investigate the relationship with

radiological grade of osteoarthritis of knee at symptomatic obese patients and body mass index,

functional status.

Materials and Methods: Forty‐one patients whose BMI was more than 30 kg/m2 and diagnosed as

primary knee OA due to knee pain complaints were included in the study. The anatomic tibiofemoral

angle (aTFA) was measured on orthoro‐ entgenography by Picture Archiving Communication Systems

(PACS). Western Ontario McMaster Osteoarthritis Index (WOMAC) and knee Visual Analogue Scale

(VAS) were evaluated according to the knee which has more pain complaint.

Results: A statistically significant correlation in the positive direction was found between the decrease

in BMI and the decrease in the Lumbar VAS (Initial‐3rd month difference). However, there was a

correlation between the decrease in BMI and the decrease in knee function and VAS which was not

statistically significant.

Conclusion: It is suggested that short term knee pain due to knee OA is not directly associated with

weight loss and irreversible mechanical factors (knee varus, cartilage damage in knee joint) caused by

obesity can be the effective factor.

Kilo Vermenin Bel ve Diz Ağrılarına Etkisi

Öz

Amaç: Semptomatik osteoartrit (OA) ‘in risk faktörleri değerlendirildiğinde yüksek vücut kitle indeksi (VKİ) ‘nin, düşük eğitim düzeyi ve sosyal desteğin, depresif durumun daha fazla ağrı bildirilmesi ile ilişkili olduğu görülmüştür. Bu çalışmanın amacı, obez ve semptomatik diz osteoartriti ve bel ağrısı olan hastalarda; radyolojik evre ve vücut kitle indeksi ile fonksiyonel durum arasındaki ilişkiyi değerlendirmekti.

Materyal ve Metot: Çalışmaya diz ağrısı yakınması nedeniyle başvuran primer diz OA tanısı alan VKİ 30 kg/m2üstü 41 hasta dahil edildi. Anatomik tibiofemoral açı (aTFA), ortoröntgenografiler üzerinde Resim Arşivleme İletişim Sistemleri (PACS) ile ölçüldü. Ağrı yakınması daha çok olan dize göre Western Ontario McMaster Osteoartrit Indeksi (WOMAC) ve görsel ağrı skalası (VAS) ile değerlendirildi.

Bulgular: VKİ’deki düşme ile bel ağrısı VAS’daki (0‐3.Ay Fark) düşme arasında pozitif yönde istatistiksel olarak anlamlı korelasyon gözlenmiştir. Fakat VKİ’deki değişim ile diz fonksiyonları ve VAS arasında pozitif yönde düşme gözlenirken istatistiksel olarak anlamlı bulunmamıştır.

Sonuç: Obez diz osteoartiritine bağlı kısa dönem diz ağrılarının kilo vermek ile direk bağlantısı olmayıp, fazla kilonun yol açtığı geri dönüşümü olmayan mekanik faktörlerin (dizin aşırı varusu, diz eklemindeki kıkırdak hasarı) etken olduğunu düşündürmüştür.
