Total knee arthroplasty with unresurfaced patella

In this prospective study, we evaluated the outcome of total knee replacement without resurfacing of the patella in 97 cases. There were 55 males and 42 females. The age at the time of surgery ranged from 65 to 81 years. All patients underwent cementless total knee replacement [Profix, Smith and Nephew]. The patients were assessed, at intervals of 6 weeks, 6 months and 18 months postoperatively. The mean follow up of the last visit was 15.3 months. We used the knee society score and the patellar score for assessment. According to the final, knee society score results, the outcome was excellent in 35 cases [36.1%], good in 42 cases [43.3%], fair in 12 cases [12.4%] and poor in 8 cases [8.2%]. The patellar score was satisfactory [excellent and good] in 83 cases [85.6%] and poor in 13 cases [14.4%]. The results of total knee replacement with the implant design used in this study and routine patellar retention provided satisfactory mid-term outcome and a high degree of patient satisfaction
