The Duracon total knee replacement and its forerunner the Porous-Coated Anatomic (PCA) knee system have been associated with good results. This study reviews a series of 181 knee replacements performed with these systems by seven general orthopedic surgeons with follow-up to a mean of 6.7 years. The mean Knee Society knee and function scores were 72 and 68. The mean Western Ontario and MacMaster Universities Osteoarthritis Index score was 76, and the mean 12-Item Short-Form Health Survey result was 55. A mean flexion of 104 degrees was recorded, and 93.8% of patients rated their satisfaction as good to excellent. Fifty-five percent of patients had minor radiographic lucencies-these were of questionable clinical significance. Seven patients required revision. These knee systems used in a relatively low-volume general unit provide consistent results comparable with those from larger arthroplasty units.
杜拉康全膝关节置换术及其前身多孔涂层解剖型（PCA）膝关节系统都取得了良好的效果。本研究回顾了由七位普通骨科医生使用这些系统进行的181例膝关节置换术，平均随访6.7年。膝关节协会的膝关节和功能平均评分分别为72分和68分。西安大略和麦克马斯特大学骨关节炎指数平均评分为76分，12项简短健康调查平均结果为55分。记录的平均屈曲度为104度，93.8%的患者对手术满意度评为良好至优秀。55%的患者有轻微的影像学透亮区——这些区域的临床意义存疑。7例患者需要翻修。在一个手术量相对较少的普通科室使用的这些膝关节系统，能提供与大型关节置换科室相当的一致结果。
