Abstract
INTRODUCTION. The number of patients with obesity and coxarthrosis increases progressively every year. However, there is currently no consensus on the tactics of preoperative management of patients with obesity and osteoarthritis of the hip joint.
The OBJECTIVE of our research was to study the effectiveness of conservative and surgical treatment of morbid obesity in patients with coxarthrosis.
METHODS AND MATERIALS. A retrospective single-center cohort study was conducted, patients with coxarthrosis were examined who were referred to the clinic for total hip arthroplasty, while the patients had a history of morbid obesity (body mass index over 40 kg/m2) before hospitalization. The cohort consisted of 115 patients, 29 men (25.2 %) and 86 women (74.8 %), the average age was 64.2±6.9 years, the average body mass index was 44.3±2.7 kg/m2. Two groups of patients were selected: 56 patients (study group I) with diagnosed coxarthrosis and morbid obesity, who voluntarily underwent conservative treatment of obesity in outpatient settings at their place of residence; the second group (group II) included 59 patients with coxarthrosis who underwent bariatric surgery.
RESULTS. Conservative treatment of morbid obesity in the presence of a primary effect of 5 % of BMI (3 months) gives a maximum weight loss by 9 months after the start of treatment, reaching 13 % (38.7±1.1 kg/m2) of the initial average. BO cause weight loss of up to 28.9 % by 6 months (32.1±1.0 kg/m2) and subsequently stabilize at about 20 % of the initial BMI.
CONCLUSION. Conservative treatment of morbid obesity in patients with coxarthrosis gives maximum weight loss by 9 months after the start of treatment, reaching 13 %, after bariatric surgery for 6 months there is a maximum weight loss of up to 28.9 % of the initial average BMI of patients.
