Knee Joint Replacement Surgery

Knee Joint Replacement Surgery

Arthritic knees can be restored through knee replacement surgery (also known as knee arthroplasty or total knee joint replacement surgery). When it comes to kneecaps, metal or plastic parts are used to protect their edges. Anyone with severe arthritis or a serious knee injury may benefit from this procedure. The knee joint can be affected by a variety of forms of arthritis.

Osteoarthritis, an inflammatory joint ailment that affects primarily middle-aged and older people, may be a factor in knee joint cartilage and bone collapse. Rheumatoid arthritis, which causes inflammation of the synovial membrane and results in an excessive amount of synovial fluid, can cause pain and stiffness in the affected joints. The knee cartilage can be damaged by traumatic arthritis, which is arthritis caused by an injury. Surgery for knee joint replacements is aimed at resurfacing and resolving pain that can’t be alleviated through conventional procedures.


We use three type of knee joint replacement surgery, given below :

Computer Assisted Knee Joint Replacement

Computer-assisted total knee joint replacement surgery is a process that uses sophisticated computer imaging to guarantee the maximum level of accuracy during the treatment. With the help of a actual time infrared-based tracking system, we can get almost flawless alignment and soft tissue balance, which are the two most dangerous mechanisms of a successful replacement.

Knee joint replacement surgery has become a common and highly successful procedure in recent years. Recent advancements have resulted in even better long-term and accurate results. More notable and common movements can be seen in new embed plans.

Improved understanding of the role of the tendons in the knee has resulted in a greater understanding of the knee’s structural integrity. Dr. Kaushal Kant Mishra and his team are one of a select group of surgeons who have made significant progress in the preparation of knee joint replacement surgeries and use this method in the operating room. 

Surgery assisted by computer technology aims to combine the precision and accuracy of modern medical technology with human expertise. Because of this, Dr. Kaushal and his team are able to achieve a level of precision impossible with the naked eyes when it comes to insert placement. Those who undergo knee joint replacement surgery are able to return to their daily routines more quickly and with improved outcomes.

The great news for patients is that; negligibly intrusive careful strategies are continually advancing and accelerating the restoration cycle. Every one of these improvements have implied more limited clinic stays, less time on a walker and a speedier getting back to typical lifestyles. Lesser post-usable agony and negligible scar (improved cosmesis) are the immediate advantages of computer assisted surgery.

How Does Computer-Assisted Knee Surgery Work ?

The medical navigation structure uses a progressive stereotactic camera and an infrared light source to trace points in space. In surgery, a high-tech software system keeps track of the position of your bones and the surgeon’s instruments at the same time at all times.

The surgeon’s tool and the bones are linked in a way that establishes a strong connection between the two. An infrared stereotactic camera integrated into the system’s computer tracks the movement of the bones and tools. A 3-D animated model of the patient’s real knee joint is then generated by the navigation software.

In the operating room, this model can be viewed on the system monitor by the surgeon during the knee replacement procedure. As a result of this information, the navigation system can calculate the precise distances, angles, and alignment needed to insert the prosthetics.

Compared to traditional knee joint replacement surgery (commonly used), this level of precision is far better. Using this common (by eye) method can result in knee injuries, which can lead to early failure or disaster.

It’s possible that your replacement isn’t connected properly, which can lead to premature wear and failure of the procedure. In the end, your knee joint will need an early “revision” or “replacement.” The goal of avoiding a second knee joint replacement should not be overlooked.

Who Needs a Computer-Assisted Knee Joint Replacement ?

The advantages of computer-assisted surgery should be thoroughly explained to any patient who is considering a procedure like this. Computer-assisted knee joint replacement surgery provides a benefit to younger patients because of its ability to precisely align the knee joint. The young patient’s knee surgery may be able to last thanks to the improved alignment and tissue balance achieved during this treatment. There are numerous benefits to undergoing a second (or even third) procedure.

Those who have undergone leg surgery previously can also benefit from computer-assisted replacement. An exclusion of previously inserted hardware is frequently required to carry out knee surgery with traditional (non-computer-assisted) surgery. This additional surgery and hardware removal can be avoided when using the computer-assisted method. For the most part, this surgery is the most advanced and accurate method of knee surgery currently available.

Primary Knee Joint Replacement

A MEDICAL INTERVENTION, then, is a primary knee joint replacement procedure. Inserts made of metal, high-density polyethylene, or ceramic are used to replace a knee joint that has been damaged or diseased. When a patient has their first joint replacement, this is the primary process. The femur (the long thigh bone) ends at the tibia (the large lower leg bone), making your knee a pivot joint (tibia).

The femur and tibia are covered by a smooth ligament in a strong knee. Twisting your knee is made easier by the smooth ligament, which allows the two bones to glide over each other. With the help of the muscles and tendons surrounding the knee joint, you can walk without pain.

The femur’s and tibia’s smooth ligament layers can wear out. Smooth surfaces can start to feel like sandpaper when they’ve been around for a long time. When you move your leg, the bones granulate and you experience pain and/or solidity. You will need knee replacement surgery if you are in this situation 

This degeneration can be caused by a wide range of factors, such as the following:

  1. Arthritis
  2. Trauma (fracture)
  3. Increased stress e.g., overuse, overweight, etc.
  4. Connective tissue disorders
  5. Inactive lifestyle etc.
  6. Side effect from medicines, such as steroids
  7. Inflammation e.g., Rheumatoid arthritis

Revision Knee Joint Replacement

Knee joint replacement surgeries can fail for a variety of reasons as time goes on. When this happens, your knee may be swollen and in pain. Everyday tasks may become difficult if it is too firm or unbalanced. The surgeon may recommend that you have a second knee surgery—revision total replacement—if your first knee surgery fails. The genuine prosthesis is removed and replaced with new ones by your surgeon during this procedure.

Revision surgery is distinct from the original procedure, despite the fact that both aim to relieve pain and restore function. Getting good results takes a lot more time and effort, as well as knowledge of the implantations and tools needed to complete this more difficult process.

Revision surgery can take many forms. An element of the prosthesis may only require one revision or re-implant. It’s possible that all three elements of the knee joint—femur, tibia, and patellar—may need to be removed to make room for bone graft or augments (metal pieces that serve as replacements for missing bone).

Before the knee joint replacement procedure :

  • Your surgeon will describe the process to you and request you the chance to ask any query that you might have about the treatment.
  • You will be asked to signature a agreement form that gives your consent to do the treatment. Read the form cautiously and ask query if something is not understandable.
  • In adding to a whole medical past, your surgeon may execute a whole physical checkup to confirm you are in good health before experiencing the treatment. You can go for blood test and other tests.
  • Inform your if you are delicate to or are allergic to any medications, latex, tape, and anesthetic agents (local and general).
  • Inform your surgeon of all medications and herbal supplements that you are using.
  • Inform your surgeon if you have a bleeding disorders past or if you are taking any anticoagulant (blood-thinning) medications, aspirin, or other medications that disturb blood clotting. It may be important for you to break these medications prior to the treatment.
  • If you are pregnant or doubtful that you are pregnant, you should inform your surgeon.
  • You will be suggested to fast for eight hours before the treatment, usually after midnight.
  • You may get a soothing prior to the knee joint replacement treatment to help you calm.

How long does it take to recover from a revision knee joint replacement ?

It could take up to a year for you to be completely recovered. Three to six months after undergoing knee joint replacement surgery, the majority of patients are ready to return to work and resume some of their regular activities (this may not include exercise or other physical activities).

What is the success rate of revision knee joint replacement?

Knee implantations are expected to last 15 to 20 years in 85 percent to 90 percent of people who undergo total knee joint replacement surgery. The earlier a knee joint replacement surgery is performed, the more likely it is that the patient will require a second surgery to clean and fix the implants that were initially placed in the knee joint.
