Arthroscopic Modified Broström Operation for Lateral Ankle Instability / 대한정형외과학회잡지

Lateral ankle sprain is the most common ankle injuries. Patients who fail conservative treatments are candidates for modified Broström operation (MBO). Traditionally, the primary surgical treatment performed is the open MBO. Recently, there has been an evolution in the arthroscopic treatment of lateral ankle injury. Several reports reveal biomechanically equivalent results of arthroscopic vs . open MBO when using matched cadaver pairs. Also there was no difference in the clinical or radiologic outcomes between the arthroscopic and open MBO in randomized controlled trial. Therefore, arthroscopic MBO is reasonable and good alternative treatment for lateral ankle injury. Actually new techniques of arthroscopic treatment for ankle injury is introduced about arthroscopic syndesmotic repair and arthroscopic deltoid repair. Arthroscopic techniques for ankle injuries seem to develop further in the future.

Treatment of Osteochondral Lesions of the Talus in Athletes / 대한스포츠의학회지

The definition of osteochondral lesion of the talus (OLT) is any defect involving both the articular surface and the subchondral bone of the talus. Many of these lesions are associated with acute ankle injury. Although many classification schemes for OLT have been proposed, Berndt and Harty's 4-staging classification is most commonly used. Stage 4 lesions and symptomatic lesions under grade 3 are usually recommended to surgical treatment. The treatment approach for athletes should be more elaborate due to the need for an early return to play. Several different types of treatment are described for OLTs in athletes, including bone marrow stimulation, osteochondral autograft transfer system, and autogenous chondrocyte implantation. Osteochondral autograft transfer system shows good clinical outcome and has the advantages that could be applied to large defect and recurred lesions, however, it has some disadvantages in terms of the complications related with the donor site and the difficult approach to the medial lesions. Although autogenous chondrocyte implantation has been extensively applied for treating OLTs with successful clinical outcomes, it has some limitations that apply to athletes in terms of the 2-stage and complicated procedure and the insurance issues. Bone marrow stimulation being a simple and cost-effective procedure associated with a low complication rate and low postoperative pain has faster return to play and is recommended the first-line treatment for the OLTs of athletes.
