What procedure involves using two needles to flush out the superior joint space?

  1. Arthroscopy

  2. Arthrocentesis

  3. Arthroplasty

  4. Osteotomy

The correct answer is: Arthrocentesis

Arthroscopy (A) is a minimally invasive surgical procedure where a small incision is made and a specialized camera is used to view the inside of a joint. This is not the same as using two needles to flush out the joint. Arthroplasty (C) is a type of joint replacement surgery and does not involve using needles to flush out a joint. Osteotomy (D) is a surgical procedure where a bone is cut and reshaped, and it does not involve the use of needles to flush out a joint. Therefore, of the given options, the most appropriate answer is B Arthrocentesis, which is a procedure where fluid is aspirated or injected into a joint using two needles. This is commonly used to diagnose and treat joint conditions such as arthritis or infection.
