The arthroplasty was performed via an anterior midline incision and medial parapatellar approach. All patients received Leicester Patellofemoral Prosthesis (Corin). One patient had a revision procedure following a failed PFJR performed elsewhere. The age of the patient at the time of operation ranged from 31–68 years (Mean age 50.3 years). The duration of follow-up was 6 months to 88 months (Mean 36 months). The results were evaluated using the Oxford Knee Score.
We reviewed the outcome of 116 primary cemented Omnifit 7000 series total knee arthroplasties implanted into 108 patients over a period of two years with a mean follow up of 68 months (range, 48–90). During the review period, 12 patients died and 8 patients were lost to follow up (24 knees). The mean Knee Society score postoperatively at review was 86 (range, 65 to 95). The mean functional score at review was 76 (range, 60 to 100). The mean range of motion at review was 100 degrees (range, 85 to 115). Radioluscent lines greater than or equal to 1mm in width were present in 9 (10%) of the femoral views, 12 (14%) of the tibial AP views, 4 (4%) of the tibial lateral views and there was no evidence of progression of the radioluscent lines. There were three revisions; one because of an early deep joint infection, on due to instability in the AP plane and one due to aseptic loosening. The clinical and radiographic results with a minimum five year follow up show very satisfactory results. The Omnifit 7000 series provides results, which compare well with other cemented arthroplasties in the medium term.
