Knee Arthroscopy

Knee arthroscopy is a technique involving a surgeon examining problems with a small instrument called an arthroscope and fixing them. It is a less invasive surgical procedure used both to diagnose and to treat conditions in the joints.

The arthroscope is a fiber-optic telescope that can be inserted to examine and treat a variety of conditions in a joint (usually the knee, shoulder and ankle). A camera is mounted to the arthroscope and the image is visualized on a TV display. The majority of arthroscopic procedures are conducted as a day-only procedure and are typically performed under general anesthesia. A typical procedure is knee arthroscopy.


In assessing and treating the following conditions, arthroscopy is useful:

  • Floating cartilage (meniscus) torn: The cartilage is cut to a stable rim or to a stable edge
  • Repaired periodically
  • Surface torn (articular) cartilage
  • Removal of loose bodies and cysts (the cartilage or bone that has fallen off).
  • The repair of the ligament Anterior Cruciate
  • Knee-cap (patello-femoral) disorders
  • Infected knees washout
  • Specific uses of diagnosis


There is a camera attached to the arthroscope, and this helps doctors to check the joint for injury. Very minor cuts in the skin are required for the operation, which gives arthroscopy some benefits over more invasive procedures.

Knee arthroscopy surgery has become common because it typically requires shorter recovery times. The operation usually takes less than 1 hour and there are rare serious complications.

The other ligaments and cartilage in the knee may be weakened at the time of the injury. The medial collateral ligament can most frequently tear, and either the medial or lateral meniscus can tear. This can result in the knee joint locking

In order to minimize swelling and improve the range of motion through adequate exercises, initial treatment is necessary. To remove a fracture, an x-ray is taken and an MRI scan is periodically scheduled to further test the knee joint. The presence of bone bruising on the MRI scan is very normal. Explains Dr. Pranjel Pipara the best ACL Surgeon/Orthopedic Surgeon in Gujarat, India

For patients whose knees give way on repeated occasions, ACL reconstruction surgery is recommended. ACL surgery might not be appropriate if you have built up your thigh muscles and your knee does not give way. In order to maintain the knee for the future, there is a theoretical case for doing an ACL reconstruction. It has been found to have broken cartilage.

Advantages of Knee Arthroscopy

Knee arthroscopy is less invasive than surgical types that are open. Using a very small instrument, an arthroscope, which passes through an incision in the skin, a surgeon may diagnose problems and function.

In diagnosing a variety of problems, knee arthroscopy surgery can be helpful, including:

  • Persistent pain and weakness in the joints
  • Cartilage weakened
  • Bone or cartilage pieces floating
  • A fluid accumulation, which must be drained,

Arthroscopy is all that is needed in most of these instances. Instead of other surgical procedures, people can prefer it because arthroscopy often involves:

  • Less damage to tissues
  • A quicker cycle of recovery
  • Less stitches
  • After the treatment, less discomfort
  • A reduced chance of infection, since there are smaller incisions

Anatomy of the Knee

The largest joint in the body is the knee. The femur, tibia and patella make up the knee joint (knee cap). Articular (surface) cartilage is lined with all these bones. This articular cartilage functions as a shock absorber and helps the knee to travel on a smooth, low friction surface. Two floating cartilages called menisci lie between the tibia and femur. The medial (inner) meniscus and the lateral (outer) meniscus rest and are mobile on the cartilage of the tibial surface. Menisci also act as stabilizers and shock absorbers. Ligaments that are both in and outside the joint support the knee. The collateral ligaments of the medial and lateral protect the knee from repetitive side-to-side motion. The anterior and posterior cruciate ligaments of the (internal) protect the knee from buckling and giving way. A capsule (envelope) that creates a larger one is surrounded by the knee joint

How is Knee Arthroscopy procedure performed?

Depending on the nature of the arthroscopy, the form of anaesthetic used for numbing pain will vary.

In order to numb only the affected knee, a doctor can inject a local anaesthetic. The doctor can use a regional anaesthetic to numb the person from the waist down if both knees are affected.

Doctors will use a general anaesthetic in some situations. In this case, during the operation, the person will be fully asleep.

They might be able to watch the operation on a monitor if the person is awake. This is totally voluntary, and certain individuals might not be comfortable watching it.

The operation begins in the knee with a few minor cuts. A pump is used by surgeons to force saline solution into the area. This would expand the knee, making it easier to see their job for the doctors.

The surgeons insert the arthroscope after the knee is extended. The camera attached helps the surgeons to explore the area and recognize any issues. Earlier diagnoses can be confirmed, and they may take photographs.

If arthroscopy will solve the problem, the surgeons can insert small tools through the arthroscope and use them to correct the problem.

The surgeons will remove the instruments after the problem is solved, use the pump to drain the saline from the knee, and patch up the incisions.

The treatment takes less than 1 hour in many cases.


Recovery from Knee Arthroscopy?

It is typically easier to recover from arthroscopy than to recover from open surgery.

On the day of the procedure, most individuals exit the hospital with clear guidance on how to manage rehabilitation.

Tips for general recovery can include:

  • To reduce swelling and discomfort, apply ice packs to the dressing and surrounding area to reduce
  • Holding the leg elevated following surgery for several days
  • Resting comfortably and regularly
  • Regularly altering the dressing
  • Using crutches and following the advice of the doctor on adding knee weight

Usually, our doctors will provide particular orders before a person leaves the hospital. For pain relief, they can also prescribe painkillers.

In certain cases, in order to reduce the risk of blood clots, physicians can suggest taking aspirin.


Recovery times can differ. In 1–3 weeks, a person may be able to return to light exercise and resume most other physical activities in 6–8 weeks.
