A 68-year-old woman with osteoarthritis had a ceramic-on-ceramic left total hip arthroplasty, including ceramic femoral head and acetabular liner. At 5 years after surgery, the patient developed onset of a very loud squeaking noise, which could be heard 25 m from her, associated with limited hip movement. Findings at revision surgery included a broken ceramic femoral head component, complete wear of the ceramic acetabular component, and black wear debris. Squeaking hip after ceramic-on-ceramic total hip arthroplasty may be associated with catastrophic failure of the arthroplasty components.
一名68岁的骨关节炎女性接受了左全髋关节陶瓷对陶瓷置换术，包括陶瓷股骨头和髋臼内衬。术后5年，患者开始出现非常响亮的吱吱声，在距离她25米处都能听到，同时伴有髋关节活动受限。翻修手术的发现包括陶瓷股骨头部件断裂、陶瓷髋臼部件完全磨损以及黑色磨损碎屑。陶瓷对陶瓷全髋关节置换术后出现髋关节吱吱声可能与关节置换部件的灾难性故障有关。
