Patellar Ligamenet Length after Anterior Cruciate Ligaament Reconstruction

Abstract

We studied changes in patellar ligament length after reconstruction of the anterior cruciate ligament using either the middle of the patellar ligment as an autogenous graft or a Dacron prosthesis wrapped into the ilio-tibial tract. The mean change in length in the ligament graft group was 1.9%; in the Dacron group it was 1.5%. The change in length was no significanat in both groups. There was shortening of 7% or more in these groups.
