Gross osteolytic tibia tunnel widening with the use of Gore-Tex anterior cruciate Ligament Prosthesis: a radiological, arthrometric and clinical evaluation of 17 patients 13-15 years after surgery.
Acta orthopaedica, 2005Co-Authors: Olle Muren, Lars Dahlstedt, Eva Brosjö, Mats Dahlborn, Nils DalénAbstract:Background Postoperative widening of the bone tunnels have been found after anterior cruciate Ligament reconstruction using autologus bone-patellar tendon-bone or hamstring tendon grafts. These changes seem to be of no clinical significance in a short to midterm follow-up. We investigated if a synthetic graft evokes the same bone tunnel widening and if it is of clinical significance in a longterm follow-up.Methods We examined 17 patients, 13–15 years after their anterior cruciate Ligament reconstruction using a Gore-Tex Ligament Prosthesis. The follow-up consisted of clinical examination, K-1000 arthrometric measurement, Tegner, Lysholm and IKDC scores, and CT examination of their tibia bone tunnels. 6 patients had been reoperated before follow-up, 3 because of graft rupture and 3 because of effusion and/or pain.Results 5 patients were graded as normal (n = 2) or nearly normal according to the IKDC score, and 4 of these patients still had their Gore-Tex Prosthesis intact. 15 of the patients had a tibia bo...

These changes in the bone tunnels were in some cases without symptoms and could not be detected with arthroscopy, clinical examination, arthrometry or evaluation scores. We do not know whether they are progressive. Interpretation Based on our findings, we recommend that patients who have had a Gore-Tex anterior cruciate Ligament reconstruction should be examined not only clinically or by questionnaire, but also with CT.

Cruciate Ligament Prosthesis vs. augmentation: A randomized, prospective 5-year follow-up of 41 cases
Acta orthopaedica Scandinavica, 1993Co-Authors: Lars Dahlstedt, Nils Dalén, Ulf Jonsson, Per AdolphsonAbstract:In a prospective study, 18 patients were randomized to a Prosthesis and 23 patients to the Kennedy Ligament Augmentation Device (LAD) because of functional instability due to old anterior cruciate Ligament injuries. The operations were performed with use of a modified over-the-top technique. At the last follow-up (5 years), postoperative improvements in scores were maintained for both groups, but LAD-recon-structed patients had better Lysholm and activity scores than the Goretex group. The achieved postoperative improvement in anterior stability (KT-1000) did not deteriorate for either of the groups during the 5-year follow-up. The Goretex patients had more effusion and pain and more secondary operations.
