Background: The Asian lifestyle requires deep hip flexion, which increases the risk of dislocation. Hence, Asian total hip arthroplasty (THA) patients may have problems postoperatively. This study aimed to 1) document quality of life (QoL), Asian lifestyle-related items (five postures that require deep hip flexion), and perceived satisfaction in patients who underwent THA in Japan versus Korea, 2) assess the differences in QoL and Asian lifestyle-related items by patient lifestyle, and 3) identify the factors predicting QoL. Methods: This cross-sectional study included 222 THA patients. Korean patients completed the questionnaires. Japanese patients were then matched with Korean patients by age, sex, and post-THA period. Assessed parameters included QoL measured by the EuroQoL, Oxford hip score (OHS), Asian lifestyle (measured by the Asian lifestyle-related items), and perceived satisfaction (measured by the five items of postoperative satisfaction). Multiple regression analysis was used to determine the predictors of QoL. Results: Compared with Korean patients, Japanese patients had better QoL, but more difficulty performing postures requiring deep hip flexion. Greater QoL was associated with greater satisfaction. The predictors of decreased QoL after THA were lower OHS in both countries, worse squatting ability in Japan, and worse leg-crossing ability in Korea. Conclusions: In Japan and Korea, the OHS is an important predictor of QoL after THA.
