Complications in foot and ankle arthroscopy

Arthroscopy of the foot and ankle has become an important diagnostic and therapeutic tool for the orthopaedic surgeon. A thorough knowledge of foot and ankle anatomy and intraarticular anatomy is critical to avoid complications in foot and ankle arthroscopy. Numerous complications can occur in foot and ankle arthroscopy, such as neurologic, tendon, and ligament injuries, wound complications, infections, and instrument breakage. The most common complication is neurologic injury. The overall complication rate is 9%. Most complications associated with foot and ankle arthroscopy are transient and tend to resolve within 6 months. The only complication that persisted at 10 years followup was a neurologic injury, specifically, numbness at the incision site. Because the difficulty of procedures has increased, so has the complication rate. Knowledge of the more common complications in foot and ankle arthroscopy and improved techniques and instruments may reduce the overall complication rate.
