Summary
In a series of 356 arthroscopies of the knee joint 127 patients were explored by arthrotomy. A Storz arthroscope was introduced through the patellar tendon, and we alternated between the 30° and 70° optical systems in the same trocar sheath. The 30° system was used for inspection of the superior, anterior, medial and lateral compartments, and to lead the tip of the instrument to the posterior part of the joint. The 70° telescope was then used, providing a good view of the posterior cruciate ligament and the posterior horn of the menisci and their attachments. It also allowed direct inspection of the posterolateral and posteromedial compartments. No major diagnostic error was made by the arthroscopist in the 127 patients operated on as a result of the findings of endoscopic examination. Arthroscopy with the use of both 30° and 70° telescopes at the same session gives high diagnostic accuracy and detailed, exact pre-operative diagnosis.
Résumé
Sur une série de 356 arthroscopies du genou 127 patients ont été arthrotomisés. Un arthroscope de Storz est introduit au travers du tendon rotulien et l'on utilise alternativement les systèmes optiques de 30° et de 70° dans la même gaine de trocart. Le système de 30° sert à l'inspection des compartiments supérieur, antérieur, interne et externe, et à diriger l'extrémité de l'instrument jusqu'à la partie postérieure de l'articulation. Le système de 70° est ensuite utilisé, donnant une bonne vue du ligament croisé postérieur et de la corne postérieure des ménisques ainsi que de leurs insertions. Il permet également l'inspection directe des compartiments postéro-externe et postéro-interne. Chez les 127 patients opérés en fonction des résultats de l'endoscopie, aucune erreur majeure de diagnostic n'a été décelée. Grâce à l'utilisation simultanée des optiques de 30° etde 70°, l'arthroscopie donne des renseignements précis et permet un diagnostic pré-opératoire détaillé et exact.
