Abstract: BACKGROUND: More and more patients received the total hip arthroplasty, and the acetabular loosening occurrence is increasing day and day. Commonly used operative methods include structural bone graft, morselized bone grafting and titanium mesh reconstruction, tantalum metal pads reconstruction, Jumbo cup and Cup-Cage technology.  
OBJECTIVE: To summarize the clinical effect of the individual biological acetabular cup application in acetabular loosening after total hip arthroplasty and supply a feasible method for the hip revision.
METHODS: Eleven patients with acetabular loosening after the total hip arthroplasty undergoing acetabular revision used individual biological acetabular cups admitted at Pingdingshan Medical District Second Department of Orthopedics, the 989 Hospital of Chinese People’s Liberation Army Joint Logistics Support Force between March 2017 and March 2019 were included in this study. Of them, there were 7 men and 4 women, with the age of 55-71 years. The individual biological cups were used in the hip revision surgery and followed up for 3 years. Harris score, visual analogue scale score and absolute length difference of both lower limbs were recorded preoperatively and at final follow-up. X-ray films were observed to assess hip functional recovery and bone ingrowth.  
RESULTS AND CONCLUSION: (1) All patients were underdone by the same doctor, followed up for 3 years and none lost. Among them, one case had symptoms of sciatic nerve, orally took mecobalamin tablets and recovered in 6 months. (2) Harris score, visual analogue scale score and absolute length difference of both lower limbs were significantly improved during the last follow-up (P < 0.05). (3) Last X-ray films showed good bone ingrowth. (4) These results imply that the individual biological acetabular cup application in acetabular loosening after total hip joint arthroplasty can restore the primary stability, restore ideal joint function and better bone ingrowth, and provide a feasible method for hip revision.
