Abstract
A retrograde resection apparatus may include a cutting blade including a slot defined in the cutting blade, a recess defined in at least a portion of the slot, a screw, including a proximal end and a distal end defining a bore therethrough, a shaft having a distal end and a proximal end, wherein the shaft passes through the bore and the distal end is configured to be received in the recess, and a biasing device configured to bias the shaft against the cutting blade. In addition, the apparatus may include a tether, a first portion of which is affixed to the cutting blade and a second portion of which passes through the bore.
