Arthroskopische Außenbandrekonstruktion des Sprunggelenks
摘要
Injuries of the lateral ligaments of the ankle are among the most frequent musculoskeletal traumas. Despite high success rates of primary conservative treatment, a considerable proportion of patients develop chronic lateral ankle instability. In addition to the classical open modified Broström technique, arthroscopic procedures have increasingly been established in recent years, enabling simultaneous diagnostics and treatment of intra-articular concomitant pathologies.
ObjectiveThe aim of this study is to provide an overview of arthroscopic reconstruction of the lateral ankle ligament complex and to describe modern surgical techniques, biomechanical principles, indications and clinical outcomes.
Material and methodsA narrative review of the current literature was performed addressing the background, diagnostics and both conservative and surgical treatment options for chronic lateral ankle instability. The focus was placed on the arthroscopic modified Broström technique, all-inside procedures and augmented techniques using SutureTape (InternalBrace). In addition, biomechanical aspects, indication criteria and postoperative treatment concepts are discussed.
ResultsArthroscopic procedures demonstrate functional outcomes that are at least comparable to open techniques, while being associated with lower soft tissue morbidity and reduced complication rates. The arthroscopic modified Broström technique enables an anatomical refixation of the anterior talofibular ligament. All-inside techniques minimize additional surgical incisions. Augmentation with SutureTape increases the primary stability and enables early functional rehabilitation with a faster return to sports activity.
DiscussionArthroscopic lateral ligament surgery has now become an established minimally invasive treatment option for chronic lateral ankle instability. The choice of technique should be individualized, taking tissue quality, degree of instability, athletic demands and associated pathologies into account. A precise anatomical reconstruction and appropriate patient selection are crucial for long-term treatment success.
