Knee Replacement Surgery


Knee replacement, also referred to as complete knee replacement or knee arthroplasty, is a surgical procedure that resurfaces a knee that has been damaged by arthritis. Metal and plastic components are used to cover the extremities of the bones that make up the knee joint, as well as the kneecap. This procedure may be worth considering if you have severe arthritis or a catastrophic knee injury.

The knee is made up of the thighbone’s lower end,thetibia’shigher-end,and the kneecap. Articular cartilage,as smooth layer that protects the bones while allowing them to move easily, covers the ends of these three bones where they join. The menisci are found between the femur and tibia. The”resistance to shock” that these C-shaped wedges provide cushions to the joint.

The shin and tibia remain held together by large ligaments, which give stability. The knees are supported by the lengthy thigh muscles. A thin membrane called the synovial membrane covers the remaining surfaces of the knees. Inahealthyknee, this membrane releases a fluid that softens the cartilage and efficiently eliminates friction.

What is an arthroscope’s purpose?

An arthroscope is a thin tube that is introduced into the body to observe internal organs. The kit includes a lens system, a small video camera, and a viewing light. The camera is linked to a monitoring system, which allows a surgeon to keep an eye on the process as it occurs. In addition to the arthroscope, other tools that are inserted through a second cut or incision are frequently used. Gripping, cutting, and probing are all done with these devices.

Which arthroscopic procedures are performed?

Arthroscopy or a combination of arthroscopy and open surgery is used for the following procedures:

– Rotator cuff repair – In the knee or shoulder, torn cartilage (meniscus) is repaired or resected.

– Reconstruction of the anterior cruciate ligament (ACL) in the knee

– Synovium is removed from the knee, shoulder, elbow, wrist, or ankle – The carpal tunnel in the wrist is opened.

– Ligament reattachment – Loose bone or cartilage removal from the knee, shoulder, elbow, wrist, or ankle

What is the arthroscopy procedure?

Even though arthroscopic surgery is less invasive in terms of recovery than open surgery, it still requires anaesthetics and specialized equipment in a hospital operating theatre or outpatient surgical suite. You will be given a general, spinal, or local anaesthetic, depending on the joint or suspected condition.

A small indentation will be made to implant the arthroscope (about the size of a buttonhole). To see additional parts of the joint or implant other instruments, different incisions may be required.

During corrective surgery, specific tools are delivered into the joint through accessory incisions. Initially, arthroscopy was solely used to plan open surgery as a diagnostic tool. Arthroscopy techniques may now be utilized to treat a wide spectrum of disorders because of the advancement of better instruments and surgical procedures.

After surgery, the tiny incisions will be wrapped with a bandage. You will be moved to a recovery room from the operating room. Many people just need a tiny dose of pain medicine.

Before being discharged, you will be given advice on how to care for your incisions, which activities to avoid, and which exercises to do to aid your recovery. During your follow-up visit, the surgeon will examine your incisions, remove any sutures if required, and review your rehabilitation plan.

The severity of your problem will influence the amount of surgery and recovery time required. Occasionally, during arthroscopy, the surgeon will discover that the damage or condition cannot be successfully addressed by arthroscopy alone. More extensive open surgery may be performed while you are still sedated, or after you have discussed the findings with your physician.

What are some of the benefits of arthroscopy?

People may prefer it to other surgical options since arthroscopy typically involves:

– tissue injury is decreased – healing time is shortened – fewer stitches are used

– Because the incisions are smaller, there is less pain and a lower risk of infection after the procedure.

Arthroscopy, on the other hand, is not suitable for all patients. There is limited evidence that knee arthroscopy can help people with osteoarthritis or degenerative diseases.

Keep an open mind and ask as many questions as you need to understand why your doctor advises you to avoid arthroscopic surgery.

Arthroscopic surgery has progressed from a desirable alternative to open surgery to the standard of therapy for many types of joint problems. Arthroscopy isn’t a one-size-fits-all technique, though.
