NATURAL HISTORY OF POLY L-LACTIDE BIOABSORBABLE SCREW FOLLOWING TIBIAL FIXATION OF HAMSTRINGS GRAFT IN ACL SURGERY

摘要: Purpose The purpose of this study was to assess radiologically the absorption a poly L-lactide bioabsorbable interference screw used in anterior ligament reconstruction. Methods A case series ten sequential patients undergoing reconstruction with four-strand hamstrings technique were assessed MRI scans at one, two, four, seven and years postoperatively. reported by an independent radiologist, respect resorption post changes bone. Fixation graft ACL surgery is varied from metal screw, resorbable screws made PLLA, staple fixation. advantage allow imaging knee postoperatively, perceive benefit replacement host Results No had occurred after 4 any patients. By complete progressive three. Five displayed new bone formation within tibial tunnel. Of five no demonstrable formation, fluid collection present In one these patients, revealed ganglion beyond limit We will final data years. Conclusions This has shown that take longer resorb than initial vitro data. It unclear as whether related resorption, or presence hamstring theoretical advantages bio-absorbable must be weighed against findings.
