The knee is one of the most important joints in the body. It connects the leg and thigh bones to provide assistance in supporting the body weight and in various types of movement. Arthroscopy is a medical investigative and correctional process where the joints in the body are observed and treated with the help of technological instruments. The procedure requires minimal incisions at the knee as the modern devices are sophisticated and offer a great degree of accuracy and clarity. The tissue damage and scarring are minimised and this helps the patient to recover in a quicker amount of time.
What is Knee Arthroscopy?
Knee Arthroscopy is a modern surgical technique which is used in the diagnosis and treatment of knee joint problems. The procedure will involve a small surgical incision followed by the insertion of a tiny camera known as the arthroscope. The surgeon views the inside of the joint on a screen and if necessary performs a correctional step using small instruments fitted to the arthroscope.
Uses of Knee Arthroscopy
- The procedure can be used to diagnose a large number of problems associated with the knee.
- Knee problems such as torn meniscus or misaligned patella or kneecap can be studied very closely for diagnosis and treatment.
- The torn ligaments of the knee joint can also be repaired successfully using this procedure.
- The arthroscopic knee surgery has minimal and limited risks.
- The recovery time for the patients is also very fast as the tissue damage is very small.
Need For Knee Arthroscopy
- Arthroscopy is recommended by doctors when the pain in the knee becomes severe and unbearable.
- The doctor may have already diagnosed properly and may order this procedure for greater clarity and confirmation.
- The usage of technology helps the surgeon in differentiating the finer points of the knee joint damage for proper treatment.
Injuries Treated By Knee Arthroscopy
- Ligament tears in the anterior or posterior regions.
- Tear in the cartilages between the bones in the knee i.e. the meniscus.
- Displaced or dislocated patella or the knee cap.
- Cartilages in the joint coming loose causing lot of pain.
- Baker’s cyst removal.
- Correction of fractures to the bones in the knee.
- The lining of the joint i.e. synovium getting inflamed and swollen.
Knee Arthroscopy Preparation
- Patient has to disclose all the details to the surgeon including prescriptions, over the counter medications, vitamin and other supplements being used.
- Putting a stop to the intake of aspirin or ibuprofen before weeks of surgery.
- Maintaining an empty stomach for 6 to 12 hours before surgery by avoiding solid and liquid foods.
- Patients are advised to purchase any pain relievers prescribed by the surgeon beforehand to avoid unnecessary discomfort at the postoperative stage.
Knee Arthroscopy Procedure
- Local or General or Regional Anaesthesia is given to the patient during surgery.
- Monitor is present to view the entire surgical process. The patients who are awake can also view the surgery in the monitor if they wish.
- Surgical incision or cut is made in the knee by expert hands.
- The knee is expanded with the pumping of saline or sterile salt water.
- The surgeon has a clear view of the entire knee.
- The arthroscope is inserted into one of the cuts by the surgeon.
- The joint problem and damage are closely observed on the monitor.
- The problem area is located and small tools are inserted to make the correction.
- Saline is drained and stitches are applied to close the incisions.
