Objectives: To describe a technique for arthroscopy of the fetlock joint of the dromedary

camel, and the problems that could occur during and after arthroscopy. Methods: Seven animals (4 cadaveric limbs and 3 living camels) were used in this study. Two dorsal arthroscopic portals (lateral and medial) and one palmaro-lateral portal were used. Distension of the joint capsule was affected by injecting Ringer´s lactate solution into the joint cavity. Landmarks for the dorsal arthroscopic portals were located at the Centre of the groove bounded by the lateral branch of the suspensory ligament and the large metacarpus at a point 1 cm proximal to the joint. The palmaro-lateral portal was located in a triangular area between the branch of the suspensory ligament, the large metacarpus, and the sesamoid bone, with insertion of the arthroscope in a 45° joint flexion angle.

Results: Arthroscopy of the fetlock joint via the dorso-lateral portal allowed examination

of the distal end of the large metacarpus and the proximal end of the first phalanx of the

fourth digit. Arthroscopy via a dorso-medial approach allowed examination of the distal

end of the large metacarpus and the proximal end of the first phalanx and the distal end of

the third digit. The palmaro-lateral portal allowed examination of the sesamoid bones, the synovial membrane, and the synovial villi. The main complications recorded during arthroscopy were iatrogenic articular surface injury as well as obstruction of vision with the synovial villi.

Clinical significance: This is the first work to describe the normal arthroscopy of the fetlock

joint in the dromedary camel, the arthroscopic portals, and the complications that could occur during and after arthroscopy. Further studies are required for the diagnosis of pathological changes in the fetlock joint of the dromedary camel and for arthroscopy of other

joints in the dromedary camel.
