Modified arthroscopic Brostrom procedure

•Arthroscopic Brostrom procedure allows repair of chronic lateral ankle instability and management of intra-articular lesions.•The strength of pullout with bone tunnel is comparable with suture anchor.•Arthroscopic Brostrom procedure with bone tunnels may reduce the risk of iatrogenic fracture of the lateral malleolus.

The open modified Brostrom anatomic repair technique is widely accepted as the reference standard for lateral ankle stabilization. However, there is high incidence of intra-articular pathologies associated with chronic lateral ankle instability which may not be addressed by an isolated open Brostrom procedure. Arthroscopic Brostrom procedure with suture anchor has been described for anatomic repair of chronic lateral ankle instability and management of intra-articular lesions. However, the complication rates seemed to be higher than open Brostrom procedure. Modification of the arthroscopic Brostrom procedure with the use of bone tunnel may reduce the risk of certain complications.
