Between 1978 and 1984, 183 hips in 154 patients with the uncemented Gerard double-cup arthroplasty were resurfaced. The clinical and radiographic results of the 106 original arthroplasties were reviewed after a median follow-up period of 98 months. Although many of these patients had clinically improved immediately, the Harris Hip score decreased significantly in most hips in subsequent years. No correlation was found between the clinical score and radiographic complications. Major revision surgery with removal of the double cup was performed in 54 of 183 patients, making the cumulative success rate after 132 months only 48%. Survival was significantly greater in patients younger than 50 years of age and in patients with a low body weight (Quetelet index less than 25). This high failure rate eliminates the Gerard double-cup arthroplasty, except possibly for the patient with a destructive inflammatory arthropathy for whom there are no other surgical alternatives.
1978年至1984年间，对154例采用非骨水泥型杰拉德双杯关节成形术的患者的183个髋关节进行了表面置换。在中位随访98个月后，对106例初次关节成形术的临床和影像学结果进行了评估。尽管这些患者中有许多人术后立即出现临床改善，但在随后几年中，大多数髋关节的哈里斯髋关节评分显著下降。未发现临床评分与影像学并发症之间存在相关性。183例患者中有54例接受了去除双杯的翻修手术，132个月后的累积成功率仅为48%。年龄小于50岁的患者和体重指数较低（体重指数小于25）的患者生存率显著更高。除了患有破坏性炎症性关节病且无其他手术选择的患者外，这种高失败率排除了杰拉德双杯关节成形术的应用。
