Tibiotarsal arthroscopy

Summary

The objective of this retrospective article was to describe the use of, and to determine long-term outcome of, tibiotarsal arthroscopy in dogs. The medical records of 20 client-owned dogs with tibiotarsal joint disease with arthroscopic treatment were reviewed. Long-term follow-up evaluation of lameness, force plate gait analysis, and radiographs to assess progression of degenerative joint disease (DJD) were performed. Arthroscopy was utilized in the diagnosis of talar osteochondritis dissecans (OCD), collateral ligament injury, septic arthritis, immune mediated arthritis, and a distal talar fragment. Sixteen joints with OCD treated resulted in 10/14 dogs with lameness after exercise only, progression of DJD in most cases, and chronic lameness when comparing operated to unoperated limbs with force plate evaluation at a mean follow-up of 35 months. Following treatment, three dogs with collateral ligament injury had reduced weight bearing on the operated limb, radiographic progression of DJD, and minimal lameness at a mean follow-up of 27 months. Tibiotarsal arthroscopy can be successfully used to help diagnose, and often to treat: OCD, collateral ligament injury, fractures, septic and non-septic arthritis in the dog. The minimally invasive nature of arthroscopy preserved joint stability while allowing complete examination of the articular cartilage. In most cases long term tibiotarsal DJD advancement was the rule.
