Seven-year survivorship and functional outcomes of the high-flexion Vanguard complete knee system.

Certain recreational, cultural, occupational, and religious practices may require knee flexion exceeding typical daily living activity needs. Some total knee prostheses mechanically accommodate high flexion to help meet such demands, e.g.

The relationship between pre- and postoperative range of motion utilizing three cruciate-retaining total knee prostheses.

We prospectively examined the relationship between pre- and postoperative range of motion utilizing three cruciate retaining knees with various mechanical flexion potentials, i.e., two at about 130 degrees -135 degrees (one with posterior lip and the other without) and the third at about 140 degrees -145 degrees .
