Knee surgery is a medical procedure used to treat various conditions affecting the knee joint, such as ligament tears, cartilage damage, or arthritis. There are different types of knee surgeries available depending on the patient’s condition and the severity of their symptoms. Some of the most common knee surgeries include knee arthroscopy, total knee replacement, and partial knee replacement. These procedures are performed by a specialized orthopedic surgeon and involve the removal of damaged tissue or bones and replacing them with prosthetic or artificial joints to restore the knee’s functionality. After knee surgery, patients will need to undergo a period of rehabilitation and physical therapy to regain mobility, strength, and flexibility in the knee joint.
Knee arthroscopy is a minimally invasive surgical procedure that is used to diagnose and treat problems in the knee joint. During a knee arthroscopy, a small camera (arthroscope) is inserted through a small incision into the knee joint. The arthroscope allows the surgeon to see inside the joint and identify any problems, such as damage to the cartilage, ligaments, or meniscus.
If a problem is identified, the surgeon can use small surgical instruments that are inserted through other small incisions in the knee to repair or remove damaged tissue. For example, if there is a torn meniscus, the surgeon may use a small instrument to trim or repair the tear. Knee arthroscopy can also be used to remove loose pieces of cartilage or bone that may be causing pain or catching in the joint. Knee arthroscopy is usually performed as an outpatient procedure, meaning the patient can go home the same day. The recovery time after knee arthroscopy is typically shorter than with traditional open surgery, and patients may be able to return to their normal activities within a few weeks, depending on the extent of the surgery.
A meniscus tear is a common injury that can occur in the knee. The meniscus is a C-shaped piece of cartilage that cushions the knee joint and helps absorb shock. It can tear if the knee is twisted or subjected to excessive force, such as during sports activities or other physical activities. The symptoms of a meniscus tear can include pain, swelling, stiffness, and a limited range of motion in the knee joint. In some cases, the knee may also lock or give way, making it difficult to walk or bear weight on the affected leg.
Treatment for a meniscus tear depends on the severity of the tear and the individual’s symptoms. In some cases, rest, ice, and physical therapy may be recommended to help relieve pain and improve mobility. In more severe cases, surgery may be necessary to repair or remove the damaged tissue. Arthroscopic surgery is often used to treat meniscus tears, as it is minimally invasive and allows for a quicker recovery time. After surgery, physical therapy may be necessary to help restore strength and flexibility in the knee joint.
Knee replacement, also known as knee arthroplasty, is a surgical procedure used to replace a damaged or worn-out knee joint with an artificial joint, called a prosthesis. Knee replacement surgery is usually recommended for people who have severe knee pain and stiffness that limits their ability to perform daily activities, and who have not found relief with other treatments, such as medications, physical therapy, or injections. During knee replacement surgery, the damaged bone and cartilage are removed from the knee joint and replaced with metal and plastic components that mimic the natural shape and movement of the knee joint. The procedure can be done using traditional open surgery or minimally invasive techniques.
After knee replacement surgery, patients usually stay in the hospital for a few days for monitoring and rehabilitation. Physical therapy is an important part of the recovery process, as it can help patients regain strength and mobility in the knee joint. Recovery time varies depending on the individual and the extent of the surgery, but most people can return to their normal activities within a few weeks to a few months after surgery.
