Arthroscopic Ankle Lateral Ligament Repair for Chronic Lateral Ankle Instability

Minimally Invasive lateral ligament repair of the ankle has been developed in recent years. These repairs involve threading sutures to the remnant and can be classified into three types. These include arthroscopy-assisted mini-open procedure, arthroscopic with percutaneous procedure, and all-inside arthroscopic procedures. The all-inside arthroscopic procedure is the most minimally invasive procedure because all steps are performed arthroscopically through one portal. Further, since it is possible to suture the ligament with a direct arthroscopic view all-inside arthroscopic procedures can be performed anatomically. In this chapter, the authors provide the history of arthroscopic lateral ankle ligament repair and a recommended procedure for all-inside arthroscopic ankle lateral ligament repair using a modified lasso-loop stitch technique.
