Popis: Objective To evaluate the mid‐term clinical and radiographic results of revision total hip arthroplasty (THA) using jumbo cups in Chinese patients. Methods We retrospectively studied 61 patients (63 hips; 29 men [30 hips], 32 women [33 hips]) who underwent acetabular revision with jumbo cups between January 2001 and April 2016 at our institution. The mean age at the index operation was 59.4 ± 11.4 years. The mean body mass index of the patients was 24.9 ± 3.8 kg/m2. Clinical evaluation was determined using the Harris hip score preoperatively and at follow up. Major complications (including instability, sepsis, and revision of the femoral or acetabular component) were recorded. Radiographic measurements included inclination and anteversion angles of the acetabular components, and the vertical and horizontal distances of the centers of rotation (V‐COR and H‐COR, respectively). In the 42 patients with normal contralateral hip joints, the postoperative V‐COR and H‐COR were compared between right and left sides. Their improvement in leg‐length discrepancy (LLD) after revision THA was also evaluated. Cup survival was evaluated using the Kaplan–Meier analysis. Clinical and radiographic outcomes were analyzed. Results Mean follow up was 5.7 years (2–16 years). At the latest follow‐up, the average Harris hip score (preoperative vs postoperative values) had improved from 46 to 83 (P
