We report a 52-year-old female with end-stage osteoarthritis of the hip accompanied by acetabular dysplasia in whom quality of life (QOL) was improved by Kampo treatment.When she was 42 years old, she developed pain in the left hip joint, and early-stage OA of the hip was diagnosed by hip joint x-ray. Therefore, she took NSAIDs, and received conservative therapies such as diet and muscle training. However, pain in the hip joint increased and her activity of daily life (ADL) decreased at the age of 50, although she continued to receive the conservative therapies. At the age of 52, she consulted our department requesting Japanese Oriental (Kampo) Medicine. Kampo formulae; Keishikaryojutsubuto (12Tab/day: Kuracie Co. Ltd. Japan), and Boiougito (7.5 g/day: Kuracie Co. Ltd. Japan), were administered. Treatment for 3 months resulted in a decrease in the left hip joint pain using visual analogue scale (VAS) and improvement of her ADL. One year later, her joint symptoms have not increased, and both the Harris hip score and the clinical evaluation criteria of osteoarthritis of the hip have improved.The course of this disease varies depending on the lifestyle of the patient, and Kampo formulations may offer safe, potent supplemental treatment.
