Total knee arthroplasties with an asymmetric tibial tray and posterior femoral condyles were implanted in 224 knees. Follow-up averaged 6.3 years. All components were cemented, all patellae were resurfaced, and all femoral components were cruciate-substituting. Postoperative alignment averaged 3.3° valgus. Radiolucencies were absent around 116 knees (66%). No components were radiographically loose. Knee Society scores averaged 85 postoperatively and modified Western Ontario and McMaster Universities Index scores averaged 82. Postoperative flexion averaged 114°. Ten knees required manipulation for arthrofibrosis. Lateral release was necessary in 62 knees (28%). No revisions were required for aseptic loosening. Survivorship free of additional surgical procedures was 97% at 5 years. Compared with other series by designing surgeons, similar excellent survivorship was seen but with a higher lateral release rate.
