Human Arthroscopy • Interest dates back to Roman times • The lichtleiter-1806 • Incandescent light bulb-1879 • Cystoscope developed • Arthroscopy-1918 • Evaluation of the human stifle • Modern arthroscopy-1959
Veterinary Arthroscopy • Large animal arthroscopy-early 1970s • Well accepted mid 1980s • Small animal arthroscopy-late 1970s • Further evaluated in 1980s
Advantages • Enhanced visualization • Improved precision • Magnification • Evaluation of different compartments • Decreased post operative pain • Earlier return to normal activity
Disadvantages • Steep learning curve • Video game players at advantage • Potential need for conversion • Based on arthroscopic findings • Cost of instrumentation • Purchase • Repair
Potential Complications • Extravasation of fluid into soft tissues • Collapses the joint • Increased surgical time • Iatrogenic trauma to joint surface • Experience • Inappropriately sized scope • Infection • Nerve damage
Instrumentation • Arthroscope • Various sizes • Diameter • Length • Lens angle • External end • Camera • Light source • Cannula interlock
Instrumentation • The tower • Monitor • Light source • Documentation • Video recording • Still images • Irrigation • Shaver
Instrumentation • Hand instruments • Probes • Grasping forceps • Knives • Curettes • Shaver/burr
Diagnostic work up • Radiographs • Elbows 3 views • Shoulder 2 views • Stifle 2 views • Sedation • Dexmedetomidine 2.5 mcg/kg IV along with Hydromorphone 0.05 mg/kg IV
Elbow Joint • Pathology • Ununited anconeal process • Medial coronoid disease • Osteochondritis dissecans • Incongruity
