The clinical results and problems of anterior criciate ligament reconstruction using the Leeds-Keio artificial ligament in a series of 28 patients who desired to participate in sports and vigorous labor were reviewed a mean of sixteen months after surgery.
Nineteen (68%) of the 28 could almost completely return to their desired activities after surgery. Lachman's test was positive in ten cases even after surgery. Although we placed the substitute at the isometric point with a special instrument (isometric positioner), Lachman's test changed into positive in eight cases with further flexion beyond 130 degrees. The cause of failure was suspected to be the lack of the elasticity of the substitute.
This procedure should be done with the correct knowledge about the problems of the artificial ligament.
