A fixation system for arthroscopic surgical procedures is disclosed. A staple is adapted to be removably secured to the end of an elongated impact-type driver-extractor device. The staple and the end of the driver-extractor are dimensioned to be received within a cylindrical cannula which guides the staple to its point of affixation within the patient\s body. Actuation of the driver-extractor permits the staple to be hammered into place. By a reversal in this procedure, a previously implanted staple can be removed from the patient.
