Causes of arthroscopic knee surgery


Arthroscopic knee surgery may be an option to treat some types of knee pain . Arthroscopic surgery is a procedure in which a small camera is inserted into the joint. Other small incisions can be used to insert tools to repair or remove damaged structures. Arthroscopic knee surgery is often called a "knee exam" or knee arthroscopy.

Many different surgical procedures, which are generally performed arthroscopically, were once performed through large incisions. The advantage of arthroscopy is that you can perform these surgical procedures without damaging the normal structures around the joint. By being less invasive, the hope is for less pain and a faster recovery.

However, arthroscopic surgery remains a serious surgical procedure, carries risks , and requires adequate postoperative rehabilitation. It is important that you understand the nature of any surgical procedure being considered, the risks involved, and the postoperative recovery that is required to achieve a successful outcome.

Reasons for arthroscopic knee surgery

Not all causes of knee pain can be effectively treated with an arthroscopic procedure. Some of the reasons to have arthroscopic knee surgery include :

  • Cartilage Surgery / Meniscus Tear : Meniscectomy is the official name for an operation that involves removing part of the cartilage from the meniscus of the knee joint. The meniscus is a shock-absorbing wedge of cartilage that sits between the ends of the bones to provide cushioning and support. Small meniscus tears can usually be trimmed to relieve symptoms of a meniscus tear.
  • Meniscus Repair: Meniscus repair is a surgical procedure performed to repair a damaged meniscus. Meniscus repair can restore normal knee anatomy and has a better long-term prognosis if successful. However, meniscus repair is a more serious operation. Recovery takes longer, and due to the limited blood supply to the meniscus, meniscus repair is not always possible.
  • ACL Reconstruction : The anterior cruciate ligament or ACL is one of the four main ligaments in the knee. The ACL is critical to the stability of the knee, and people who injure the ACL often complain that their knee is sticking out from underneath. Therefore, many patients who have suffered an ACL tear prefer surgical treatment of this injury. Most ACL operations are performed arthroscopically.
  • Removal of the mucosa: the fold is the rest of the tissue that remains from the intrauterine development of the fetus. Early in development, your knee was divided into separate compartments. The compartment partitions are gradually lost over time, but some debris remains. When this residual tissue is more visible, it is called a crease. When a crease is irritated, it is called crease syndrome . To remove irritated tissue, a fold resection is performed .
  • Lateral release : the patella moves up and down the end of the femur in the cartilaginous groove. The kneecap can slip out of this groove or even dislocate from the groove, causing pain when the knee is flexed. Lateral relaxation is done to loosen the ligaments that pull the patella out of the groove .
  • Microfracture : Microfracture is a treatment used to stimulate the growth of new cartilage in the area of damaged cartilage. During the microfracture procedure, the firm outer layer of the bone penetrates, exposing the inner layers of the bone, in which the bone marrow cells exist. These cells can access the damaged area and fill the space in the cartilage.
  • Autologous chondrocyte implantation : In this procedure, arthroscopic surgery is used to locate areas of cartilage damage and collect cartilage cells. Then , a person's own cells are grown in the laboratory and implanted back into the joint in a separate procedure, which is open surgery. no arthroscopic surgery.
  • Cartilage / Red Blood Cell Transfer: Cartilage transfer involves moving cartilage from healthy parts of the joint to damaged areas. Small cartilage plugs are removed along with some of the underlying bone and transferred to the damaged area. Plugs are taken from areas of the joint where the cartilaginous surface is not needed.

Perform arthroscopic knee surgery

Knee arthroscopy can be performed under general , regional , or local anesthesia . After proper anesthesia, your surgeon will create "portals" to access the knee joint. The portals are placed in specific locations to minimize the possibility of damage to the surrounding nerves, blood vessels, and tendons. Through a portal, a camera is placed in the joint, and through other small instruments it can be used to solve the problem. Patients who have had arthroscopic knee surgery under regional or local anesthesia can often watch their operation on a monitor to see what is causing their problem.

The length of your knee arthroscopy procedure depends on what your doctor needs to do. After your surgery, a soft bandage will be placed on your knee. Depending on the type of surgery you are doing, your doctor may or may not allow you to put weight on the affected leg. Most patients will work with a physical therapist to restore joint mobility and strength. The length of rehabilitation will also vary depending on the procedure that is performed during the operation.


Complications of arthroscopic knee surgery include infection, swelling, and blood clots in the leg. Complications after knee arthroscopy are rare and, although worrisome, knee arthroscopy is considered a low-risk surgical procedure.

Get the word of drug information

Arthroscopic knee surgery is one of the most common surgical procedures performed by a podiatrist. Various surgical procedures can be performed arthroscopically using small incisions and minimal soft tissue damage. Not all surgical procedures can be performed through small incisions, and there are some procedures that are best performed with direct images rather than with a telescope. However, arthroscopy has enormous benefits in many types of knee surgery and can help people return to sports and daily activities much earlier than before.
