title: Early results with a patient specific interpositional knee device.
abstract: The iForma ConforMIS Interpositional knee device is a recently developed patient specific implant used for the treatment of mild to moderate uni-compartmental osteoarthritis. The benefits over traditional methods of surgical management are: it is less invasive, can be performed as a day procedure and does not limit future options. Bespoke implants are produced from data extracted from MRIs. Twenty-six patients with the iForma ConforMIS interpositional knee implant from November 2007 were retrospectively reviewed. The average age was 54.7 years, The average pre-operative WOMAC score was 37.8 improving to 67.6 post-operatively. Five patients required revision. No dislocations were reported. Our early experience suggests this device is a viable and safe treatment option. However, patient selection plays an important role in the outcome following surgery and long term results should be awaited.
