Adjustable femoral resection guide

A chamfer resection guide assembly for effecting chamfer cuts into a resected distal surface of a femur in connection with a distal total knee implant, the chamfer resection guide assembly having an anterior end and comprising:

• an anchor member configured for anterior referencing of the chamfer cuts;
• a block member including one or more cutting guide slots and a femoral contacting surface for placement against the resected distal surface of the femur, wherein the femoral contacting surface is provided with a recessed region in which the anchor member is slidably engaged therein,
• wherein the anchor member comprises a second femoral contacting surface and a footplate extension that extends from the second femoral contacting surface near the anterior end of the chamfer resection guide assembly;
• and
• a camming member operably connecting the block member and the anchor member and configured for linearly displacing the anchor member and the block member with respect to each other by a camming action;
• wherein the block member is provided with a blind hole provided in the recessed region and the anchor member is provided with a blind slot, wherein the camming member is captured between the block member and the anchor member by engaging the blind hole and the blind slot, whereby turning the camming member about its longitudinal axis produces the camming action;
• wherein the camming member comprises:
• a first end engaging the blind hole of the block member;
• a second end engaging the blind slot of the anchor member;
• and
• an elastically compressible member contained between the first end and the second end and urging the first end against the block member and the second end against the anchor member.
