Anterior cruciate ligament reconstruction with the patellar tendon--augmentation or not? A 2-year follow-up of 82 patients.
The aim of this bi-centre study was to assess the possible effects of the addition of the Kennedy ligament augmentation device (LAD) in the reconstruction of the anterior cruciate ligament (ACL). The method of reconstruction used was a modification of the Brückner and Broström procedures, using the medial third of the patellar tendon tunnelled through the proximal tibia into the lateral femoral condyle and fastened with pull-out sutures. Eighty-two patients with chronic ACL insufficiency and severe symptoms of instability in spite of physiotherapy were randomly selected for reconstruction with or without a LAD. The LAD-augmented knees had the synthetic augmentation stitched to and embedded into the autogenous tissue and the composite graft was pulled through a femoral tunnel and stapled proximally. The patients were followed up regularly and the 2-year results are presented here. The outcome in both groups was good. The augmented-knee group had a larger extension deficit 1 month post-operatively compared to the non-augmented knee group but a smaller extension deficit at the 2-year follow-up. There was no difference in the median of the Lysholm knee function score but there were more patients in the non-augmented group with a lower Lysholm knee function score at the 2-year follow-up.
