There were 1 male (1 hip) and 14 females (17 hips) with a mean age of (55.1±9.1) years. There were 12 hips with Crowe type Ⅱ, 6 hips with Crowe type Ⅲ. The preoperative pelvis three-dimensional CT data in those patients were used to design integral anatomical acetabular prosthesis. The model development group used 3D printing technology to print life-size pelvis models. The acetabulum was reamed and the acetabulum cup was inserted into the socket according to conventional THA procedures. The bone defect above the acetabulum cup was filled with bone wax. The Mimics and 3-matic software were used to simulate the THA procedures, design and install the integrated anatomical acetabular prosthesis in the software development group. The operation time, the size of the acetabular cup, the volume and surface area of the acetabulum bone defect, the acetabular cup's inclination and anteversion, the horizontal distance and the vertical distance of hip rotation center were compared between the two methods. &lt;b&gt;Results:&lt;/b&gt; The study in the two groups were all based on the data of 18 hips in the 15 patients. The horizontal and vertical distances of rotation center in the model development group and software development group was (32.08±1.80) mm, (32.17±2.40) mm and (14.36±1.53) mm, (15.11±1.45) mm, respectively (both &lt;i&gt;P&lt;/i&gt;&gt;0.05). The cup size in model development group was (48.56±1.15)mm, and it was (48.77±1.22) mm in the software group (&lt;i&gt;P&lt;/i&gt;=0.160). The anteversion and inclination of the acetabular cup in the model and software groups were 23.79°±6.31°, 30.49°±11.03° and 15.17°±0.52°, 40.24°±0.58°, respectively (both &lt;i&gt;P&lt;/i&gt;&lt;0.01). The volume and surface area of the acetabulum bone defect in the model development group was (5.06±2.86) mm&lt;sup&gt;3&lt;/sup&gt; and (8.31±2.21) mm&lt;sup&gt;2&lt;/sup&gt;, respectively, while it was (4.01±2.56)mm&lt;sup&gt;3&lt;/sup&gt; and (6.83±2.71) mm&lt;sup&gt;2&lt;/sup&gt;, respectively, in the software development group (both &lt;i&gt;P&lt;/i&gt;&lt;0.05).
