Abstract
A provisional knee implant assembly includes a femoral provisional having an articulating surface and a plurality of locating openings. A patella height gauge has at least two projections which each engage with a corresponding locating opening in the femoral provisional. The patella height gauge includes at least one visual locating reference for a patella. The femoral provisional is located relative to the patella by placing the femoral provisional on a distal end of the femur; attaching the patella height gauge to the femoral provisional; overlying the patella onto the gauge; and repositioning the femoral provisional relative to the one or more visual locating references on the patella height gauge.
