What surgical therapy procedure uses two cannulas to instrument within the superior joint space?

  1. Arthrocentesis

  2. Arthroscopy

  3. Joint replacement

  4. Disc repositioning

The correct answer is: Arthroscopy

Arthroscopy is the best answer because it is a surgical therapy procedure that uses specifically two cannulas to insert instruments into the superior joint space. Arthrocentesis is not a surgical procedure but rather a diagnostic procedure that removes fluid from a joint. Joint replacement involves replacing a damaged joint with an artificial one and would not require cannulas. Disc repositioning also does not involve the use of cannulas and is typically performed through non-invasive methods. Therefore, arthroscopy is the most appropriate answer in this context.
