Arthroscopy of the Fourth and Fifth Tarsometatarsal Joints: Anatomic Guide, Operative Technique, and Four-Point Inspection.

Soft tissue impingement and arthrofibrosis of the fourth and fifth tarsometatarsal joints can be a source of intractable pain and functional impairment. Arthroscopic debridement of the fourth and fifth tarsometatarsal joints is a minimally invasive method that can provide clinical relief from soft tissue impingement pathologies associated with trauma and degenerative joint disease. Arthroscopic landmarks, four-point arthroscopic inspection, and operative technique will be reviewed.
