Arthroscopy is a surgical procedure orthopaedic surgeons use to visualize, diagnose, and treat problems inside a joint using a tube-like viewing instrument called an arthroscope. The word arthroscopy comes from two Greek words, “arthro” (joint) and “skopein” (to look). The term literally means “to look within the joint.”
In an arthroscopic examination, an orthopaedic surgeon makes a small incision in the patient’s skin and then inserts pencil-sized instruments that contain a small lens and lighting system to magnify and illuminate the structures inside the joint. Light is transmitted through fiber optics to the end of the arthroscope that is inserted into the joint. By attaching the arthroscope to a miniature television camera, the surgeon is able to see the interior of the joint through this very small incision rather than a large incision needed for surgery. The surgeon can determine the amount or type of injury and then repair or correct the problem, if it is necessary.
A meniscus tear is a common knee injury. The meniscus is a rubbery, C-shaped disc that cushions your knee. Each knee has two menisci (plural of meniscus)-one at the outer edge of the knee and one at the inner edge. The menisci keep your knee steady by balancing your weight across the knee. A torn meniscus can prevent your knee from working right.
- Stiffness and swelling.
- Catching or locking of your knee.
- The sensation of your knee “giving way”
- You are not able to move your knee through its full range of motion.
Anterior Cruciate Ligament Injury
The ACL is one of the four main ligaments within the knee that connect the femur to the tibia. The knee is essentially a hinged joint that is held together by the medial collateral (MCL), lateral collateral (LCL), anterior cruciate (ACL) and posterior cruciate (PCL) ligaments. The ACL keeps the knee stable.Injuries range from mild, such as a small tear, to severe, such as when the ligament tears completely
- A loud “pop” or a “popping” sensation in the knee
- Severe pain and inability to continue activity
- Swelling that begins within a few hours
- Loss of range of motion
- A feeling of instability or “giving way” with weight bearing
