A method and apparatus for arthroscopic surgery provides a means for retaining loose tissue within a joint so that the tissue may be readily cut and removed from the joint. The apparatus comprises a harpoon-like shaft which is inserted into the body joint and the barb on the end of the shaft is engaged with the loose tissue within the joint. The shaft is then drawn outwardly slightly to tension the loose tissue so that it can be cut to permit the removal of the tissue from the joint. A cannula is slidable over the shaft and the end portion of the cannula is bevelled to fit beneath the barb. With the cannula engagable with the undersurface of the barb the device can be removed from the joint without engaging any adjacent tissue. The completely detached tissue may then be grasped and withdrawn through an opening into the joint.
