The Columbus Knee System: 4-Year Results of a New Deep Flexion Design Compared to the NexGen Full Flex Implant
Figure 6
X-ray of a Columbus knee: a.p. view pre- and postoperatively (standing position with full weight bearing) and lateral view in maximum flexion. There is soft tissue contact of calf and tight. The reduced length of the posterior implant condyles led to bone contact of the remaining original posterior condyles with the posterior edge of the polyethylene inlay.
