The Capsular Ligaments Stabilise the Hip Joint at Extreme Ranges of Motion

Description

The presentation discusses the critical role of capsular ligaments in stabilizing the hip joint, particularly at extreme ranges of motion, and highlights the increasing trend towards joint-preserving surgical procedures. Kabelan Karunaseelan emphasizes the importance of improving capsular management in arthroscopic hip surgery to enhance exposure while maintaining stability and kinematics. The study aims to quantify the forces generated by the hip capsule ligaments, demonstrating their vital function in preventing labral impingement. The research involved testing nine human cadaver specimens, allowing for a comprehensive analysis of ligament forces in various functional positions. Key findings illustrate that the medial iliofemoral ligament produces the highest force, significantly contributing to hip stability. The results underscore the necessity of preserving the capsular ligaments during surgical interventions, particularly in femoroacetabular impingement surgeries. This study provides valuable insights into capsular management, advancing understanding to minimize complications related to joint instability.
