Results of porous-coated anatomic and duracon total knee arthroplasty

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.
