膝蓋骨近位裂の関節鏡支援内側側副靭帯修復術（インサイドアウト縫合テクニック）

Medial collateral ligament (MCL) injuries are among the most common ligamentous injuries of the knee. Although most MCL injuries have favorable outcomes with conservative treatment, surgical intervention may be considered in cases of chronic instability or in conjunction with injuries to other knee structures, such as the anterior cruciate ligament or meniscus. In this Technical Note, we describe a minimally invasive arthroscopic-assisted technique for femoral-sided MCL repair using an inside-out suture method with suture anchor fixation and internal bracing using FiberTape. This technique offers biomechanical support, proprioceptive preservation, and reduced soft-tissue trauma. Although early results are promising, further long-term studies are warranted to assess durability, clinical outcomes, and potential complications.
