What is a knee arthroscopy?

  1. A surgical procedure used to replace the damaged or worn surfaces of the knee by replacing it with an implant or prosthesis to relieve pain and increase mobility. 
  2.  An incision of a joint usually performed to gain access for a surgical procedure, such as a joint replacement. Another reason for the procedure is to provide drainage for infection.
  3.  A surgical procedure that allows a physician to view the knee joint without making a large incision through the skin and other soft tissues.  
  4. A procedure that fuses the thigh bone to the lower leg bone at the knee. Sometimes the joint bones are secured with plates and screws.

Answer:

C. A surgical procedure that allows a physician to view the knee joint without making a large incision through the skin and other soft tissues.  

Being able to break down medical terms is important for anyone working in healthcare. It helps us determine the meaning of a term.

‘Let’s break down the term arthroscopy:

arthr/o means joint; -scopy means visual examination. Arthroscopy is the visual examination of the internal structure of a joint using an arthroscope.

Knee Arthroscopy

An arthroscopy is a procedure a physician carries out to look at the knee joint without having to make a large cut through the skin and other soft tissues. 

According to the American Academy of Orthopaedic Surgeons, an arthroscopy helps a physician make a diagnosis and treat many different types of knee problems. During the procedure, the surgeon inserts an arthroscope, which is a small camera, into the knee joint and takes pictures that can be seen on a video monitor. These images help the physician to direct the small surgical instruments.

Since the arthroscope and surgical instruments are so thin and only small incisions are needed, this results in much less pain than an open surgical would with a larger incision. It also benefits the patient by causing much less stiffness in the joint and a shorter recovery time.   

A knee arthroscopy may be recommended by a physician if there is pain and inflammation involved and other nonsurgical treatments fail, such as rest, physical therapy, medications, and injections.  

A, B, and D are incorrect.

A. A surgical procedure used to replace the damaged or worn surfaces of the knee by replacing it with an implant or prosthesis to relieve pain and increase mobility is called an arthroplasty or total knee replacement.

B. An incision of a joint usually performed to gain access for a surgical procedure, such as a joint replacement. Another reason for the procedure is to provide drainage for infection. This is a knee arthrotomy.

D. A procedure that fuses the thigh bone to the lower leg bone at the knee. Sometimes the joint bones are secured with plates and screws. This is a knee arthrodesis.
