Forte ceramic head on delta ceramic liner articulation showed satisfactory midterm results without ceramic-related complication. We aimed to investigate the clinical and radiological outcomes of cementless total hip arthroplasty (THA) with forte ceramic head on delta ceramic liner articulation.
Overall, 107 patients (57 men, 50 women; 138 hips) who underwent cementless THA with forte ceramic head on delta ceramic liner articulation were enrolled. The mean follow-up duration was 11.6 years. For the clinical assessments, Harris hip score (HHS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), presence of thigh pain, and presence of squeaking were evaluated. Radiographs were assessed to search for osteolysis, stem subsidence, loosening of implants. Kaplan-Meier survival curves were evaluated.
The mean HHS and WOMAC improved from 57.1 and 28.1 preoperatively to 81.4 and 13.1 at the final follow-up, respectively. Nine revisions (6.5%) were performed; 5 hips for stem loosening, 1 hip for ceramic liner fracture, 2 hips for periprosthetic fracture, and 1 hip for progressive osteolysis around cup and stem. Thirty-two patients (37 hips) complained squeaking, in which 4 cases (2.9%) were identified as ceramic-related noises. After a mean follow-up period of 11.6 years, 91% (95% CI 87.8-94.2) were free from revision of both femoral and acetabular components due to any reason.
Cementless THA with forte ceramic-on-delta ceramic articulation showed acceptable clinical and radiological results. Serial surveillance of these patients should be performed due to the possibility of cerami- related complications such as squeaking, osteolysis, and ceramic liner fracture.
forte 陶瓷头与 delta 陶瓷衬里的关节在中期表现出令人满意的结果，没有与陶瓷相关的并发症。我们旨在研究 forte 陶瓷头与 delta 陶瓷衬里关节的非骨水泥全髋关节置换术（THA）的临床和放射学结果。
共有 107 例（57 名男性，50 名女性；138 髋）接受了 forte 陶瓷头与 delta 陶瓷衬里关节的非骨水泥 THA。平均随访时间为 11.6 年。临床评估包括 Harris 髋关节评分（HHS）、安大略西部和麦克马斯特大学骨关节炎指数（WOMAC）、大腿疼痛的存在和吱吱声的存在。评估 X 线片以寻找骨溶解、柄下沉、植入物松动。采用 Kaplan-Meier 生存曲线进行评估。
平均 HHS 和 WOMAC 分别从术前的 57.1 和 28.1 改善到最终随访时的 81.4 和 13.1。进行了 9 次翻修（6.5%）；5 髋因柄松动，1 髋因陶瓷衬里骨折，2 髋因假体周围骨折，1 髋因杯和柄周围进行性骨溶解。32 例（37 髋）抱怨有吱吱声，其中 4 例（2.9%）被确定为陶瓷相关噪音。在平均 11.6 年的随访后，91%（95%CI 87.8-94.2）的患者因任何原因免于股骨和髋臼组件的翻修。
forte 陶瓷头与 delta 陶瓷衬里关节的非骨水泥 THA 显示出可接受的临床和放射学结果。由于可能出现陶瓷相关并发症，如吱吱声、骨溶解和陶瓷衬里骨折，应对这些患者进行连续监测。
