Weight reduction before surgery on obese patients has been widely recommended, but its practical possibilities have not been elucidated so far. Operation for osteoarthrosis of the hip was offered to 130 obese patients on the condition that they reduced their weight to normal. After a minimum observation period of 1 year the weight had returned to normal, and operation was performed, in 73%. Only 5% gave up losing weight. The weight reduction averaged 8.6 kg (1-25 kg). A weight reduction of up to 15 kg was achieved within less than year by eating less (94%) or changing the dietary habits (88%), and only 3% had to be admitted to hospital.
术前建议肥胖患者减重，这一建议已被广泛采纳，但目前其实际可行性尚未阐明。130例肥胖患者接受了髋关节骨关节炎手术，条件是他们需将体重减至正常水平。经过至少1年的观察期后，73%的患者体重恢复正常并接受了手术。只有5%的患者放弃了减重。体重减轻平均为8.6千克（1至25千克）。94%的患者通过少吃或88%的患者通过改变饮食习惯，在不到一年的时间内体重减轻了15千克，只有3%的患者需要住院治疗。
