Body mass indices in patients with disabling hip osteoarthritis

Abstract

Hip osteoarthritis (OA) is a degenerative joint disease that results in substantial morbidity. The disease may be preventable in some instances by reducing risk factors associated with the disease. We undertook a study to determine whether being overweight or obese, a health risk that applies to younger and older age groups, is commonly associated with hip joint OA. The body mass indices (BMIs) of 1021 males and females ranging in age from 23 to 94 years and requiring surgery for end-stage hip joint OA were analyzed to find the prevalence of high body weights at the time of surgery. Being overweight was defined as having a BMI of 25–29.9 kg/m2 and being obese as having a BMI >30 kg/m2. BMIs indicative of overweight were recorded for 68% of the patients surveyed. Of 35 patients aged 30–39 years, 53.3% had BMIs >25, with a mean of 28.8, which nearly reaches the lower limit defined for obesity. On average, patients who had had previous surgery and complications warranting reimplantation of new surgical devices had BMIs in the obese range. Our findings suggest that a high percentage of patients with end-stage hip OA are overweight, including younger adults and those with symptoms of 3–6 months' duration. Moreover, patients whose BMIs are in the obese range may be at increased risk for removal and reimplantation of their prosthesis.

“…59, 73, 92, 95, 117 The most current evidence shows BMI is not related to hip OA. 161 What seems apparent is that obesity is probably associated with the progression of hip OA rather than onset, 127 and the therapeutic value of weight loss is important. 52, 202 …”

Leptin Induces IL-6 Expression through OBRl Receptor Signaling Pathway in Human Synovial Fibroblasts

“…The potential role of leptin in OA is supported by the relationship between high body mass index and an increased risk of OA [19]. Leptin has been detected also in synovial fluid obtained from patients with OA [20,21].…”

Do patients lose weight after total hip arthroplasty?

“…In relation to higher BMI among patients who are candidates for hip arthroplasty, some studies have correlated hip osteoarthrosis with obesity. 10 , 11 It has been observed that the great majority of the patients who are candidates for THA are outside of this ideal weight range.…”
