Anterolateral impingement is an uncommon complication of ATFL tears and secondary microinstability. Repetitive motion during the healing phase can induce the development of synovitis and focal fibrous tissue, which can be painful and produce changes in the normal biomechanics

Impingement of the distal fascicle of the anterior tibiofibular ligament or Bassett ligament. Repetitive friction with talus can lead to ligament thickening, focal synovitis, fibrosis, and abrasion to the articular cartilage of the lateral aspect of the talar dome.

Ligamentum teres anatomy:
Acetabular origin with six insertions: transverse acetabular lig., ischial and pubic margins of the acetabular notch, and attachments at the bones that converge in the cotyloid fossa (ilium, ischium and pubis). Femoral insertion into the fovea capitis

Treatment of unstable Hill-Sachs (‘off-track’ or engaging lesions) consist of remplissage procedure with arthroscopic placement of suture anchors into the HS lesion through the posterior capsule, converting the HS lesion into an extra-articular defect and preventing engagement
