Arthroscopy of the Knee

By Dr. Richard Edelson

Arthroscopy is the use of a miniature camera to view the interior of a joint. It is particularly useful when diagnosing and treating damaged or diseased knees. Using an arthroscope, an orthopedic surgeon can get a clear view of the inside of the knee and make a definite decision as to how to treat the condition.

Using high resolution cameras and state of the art arthroscopes, this technique is extremely effective in diagnosing and treating knee disorders.

The Structure of the Knee

Three bones make up the knee: The femur, the tibia, and the patella. They are cushioned at their juncture by articular cartilage, which allows the bones to work together smoothly.

The remainder of knee surfaces are coated with synovial membrane. This is a smooth, thin tissue that creates a fluid that lubricates the moving parts of the knee. This lubrication facilitates smooth functioning of the knee.

The largest joint in the body, the knee is (as stated) made up of three bones. The upper end of the shin bone, or tibia, supports the lower end of the thigh bone, or femur. There is a groove in the end of the femur that the patella, or kneecap, slides along. Strong ligaments between the femur and tibia support the structure. The thighs large muscle provides strength.

Knee Difficulties

When everything is functioning properly, the parts of the knee work together smoothly. However, the knee gets a lot of use, and everyday wear and tear can cause problems. Sports, work, injury, weakened tissues, arthritis, and aging all take a toll on the knee. Over the course of time, these things can cause a lot of pain and reduce the ability of the knee to do its job.

With arthroscopy, a number of conditions can be diagnosed and treated:

When the articular cartilage is softened and/or the surfaces of the joints are damaged, it is called chondromalacia.

Crystalline arthropathy: Gouty arthritis, rheumatoid arthritis, inflamed synovial membranes.

The patella or kneecap can become unstable or misaligned.

Arthroscopy can locate these problems.

Damage to meniscal cartilage can be visualized.

Loose and/or fragmented bone and cartilage can be located.

The posterior and anterior cruciate ligaments can become torn.

Arthroscopy is extremely useful to the orthopedic surgeon in locating and assessing all of these knee problems. The use of the modern technology helps todays orthopedic surgeon deliver efficient and effective treatment. - 17268
