A New Arthroscopic One-Needle-One-Suture Repair Technique for Scapholunate Instability

Scapholunate instability (SLI) is the most frequent cause of carpal instability. There is a plethora of repair methods with a trend towards minimally invasive techniques, with the general principles aimed at restoring the integrity of the ligament and physiological carpal kinematics. We introduce a novel, all-arthroscopic one-needle-one-suture repair technique as a potential repair technique for SLI. Utilising a single 0 FiberWire suture threaded through an 18-gauge (18-G) needle, this technique allows for precise suture placement within the scapholunate ligament complex. The suture is secured with an arthroscopic gliding knot. This method reduces the need for multiple punctures and complex suture manoeuvres, thereby streamlining the surgical procedure and providing a simpler, minimally invasive alternative for certain patients with SLI. Level of Evidence: Level V (Therapeutic).
