Objective: To (1) develop an arthroscopic approach to the subextensorius recess of the lateral femorotibial (LFT) joint in foals and (2) report its use in foals with LFT joint sepsis.
Study Design: (1) Anatomic study and (2) retrospective case series.
Sample Population: (1) Cadaveric hind limbs (n = 32 foals) to delineate the anatomy of the subextensorius recess; 13 foal limbs for cadaver surgery to assess the approach to the subextensorius recess; and (2) foals (n = 8) with LFT joint sepsis.
