Arthroscopical and clinical evaluation after isolated, augmentated aclreconstruction. A prospective study

80 patients were examined in to perform a prospective essay on the isolated substitute of the anterior crucial ligament being done by Miniarthrotomie and two channel technique. All patients received a substitute of the anterior cruciate ligament by usi ng an autogenous,TETRA-L3 augmentated bone tendon bone graft from the middl e third of the patellar ligament of the injured knee. Clinical and arthrosc opical examination was carried out in the average 28 months (24-36) after c rucial ligament reconstruction, by the routinely removal of the augmentatio n and fixation material. Clinical examination was carried out using the str ict and objective 1KDC-Score. The arthroscopical evaluation of the ACL-graf t was performed with our recently developed Score for ACL-graft evaluation (Marburger Arthroscopy Score for graft evaluation). The Score distinguishes between four stages: type I: tight, crucial ligament like structured graft , type II: a firm, more bundle like structured graft, type III: a lax, unti dy structured graft and type IV: the rudimentary graft. A statistical analy sis was performed on the question whether there is a correlation between th e clinical and the arthroscopical results, furthermore, with the Marbuger A rthroscopy Score for graft Evaluation we introduced a standardised, simple- to-use new score for the arthroscopical ACL-graft evaluation. We find a high correlation (r=0,77) between the clinical results and the ar throscopical findings, so that from clinical evaluation there might be draw conclusion to the arthroscopical expective results with high probability. Due to our previous experience we assume the Marburger Arthroscopy Score Fo r Graft Evaluation to be a standardised and simple assessment method for th e evaluation of the ACL-graft, considering pathobiomechanical influences on the ACL-substitute.
