Knee Joint Replacement Surgery

Knee Joint Replacement Surgery

Knee joint replacement surgery, also called knee arthroplasty or total knee joint replacement surgery, is a medical process to come up a knee spoiled by arthritis. Metal and plastic parts are used to cover the edge of the bones that arrange the knee joint, including the kneecap. This surgical treatment may be suggest for anyone who has serious arthritis or a serious knee injury. Several types of arthritis may disturb the knee joint. 

Osteoarthritis, a degenerative joint ailment that disturbs mostly middle-aged and grown-up people, may reason the collapse of joint cartilage and adjacent bone in the knees. Rheumatoid arthritis, which creates irritation of the synovial membrane and outcomes in extreme synovial fluid, can increase pain and toughness. Traumatic arthritis, arthritis due to injury, may create harm to the cartilage of the knee. The target of knee joint replacement surgery is to come up the parts of the knee joint that have been spoiled and to release knee pain that cannot be measured by other surgeries.

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 today become a normally performed and profoundly fruitful surgery. Late developments have brought about additional improvement in right on time and long haul careful results. New embed plans give more prominent and more typical scope of movements. 

Better comprehension of the job of the tendons in the knee has brought about improved joint soundness. Dr. Kaushal Kant Mishra and his group are among a selected gathering of specialists who have progressed preparing knee joint replacement surgeries and use this strategy in the working room.

The target of this surgery helped a medical procedure is to join the exactness and precision of computer assisted innovation with the specialists’ ability and skill. Therefore, Dr. Kaushal and his group can accomplish arrangement of inserts with a level of precision unrealistic with the unaided eye. Knee joint replacement surgery helps to their patients with improved outcomes and recuperation alongside a speedy getting back to ordinary life.

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 ?

In this technique, the medical navigation structure uses an progressive stereotactic camera and an infrared light source to trace points in space. The sophisticated software system used throughout surgery trace the position of your bones and the surgeon’s tools in relation to each other at the same time at all times throughout the treatment. 

To set up these serious relationships, specific deep indicators are linked to the bones and the surgeon’s tool. The movement of the bones and tools are then traced by an infrared stereotactic camera, which is combined into the system’s computer. The navigation software then generates a 3-D animated model of the patient’s real knee joint. 

This model is presented on the systems monitor for the doctor to see throughout the whole knee joint replacement surgery. With the data gained, the navigation system computes accurate distances and angles and alignment to confirm the maximum degree of correctness to insert the prostheses. 

This level of accuracy is far better than that attained by traditional knee joint replacements surgery (commonly used) where tools that fix the new knee alignment are literally inserted “by eye”. This usually used (by eye) method can lead to injurious surfaces in the knee, which consequences in early disaster or failure.

When your replacement is not associated accurately the forces across the components are irregular, which consequences in premature wear and failure of the surgery. The last result is the requirement for an early repeat or “revision” of your knee joint. Avoiding a revision knee joint replacement is an important objective and should be ignored if possible.

Who Needs a Computer-Assisted Knee Joint Replacement ?

Any patient who have the idea of replacement surgery should really understand the advantages of computer-assisted surgery. Younger patients in particular can advantage from the accuracy alignment related with computer-assisted knee joint replacement surgery. With the better alignment and tissue balance gained during this treatment, the young patient’s knee surgery may very well last. The advantages of  a revision (or repeat) surgery are many.

In addition, patients with surgery of former fractures of the leg can advantages more from computer-assisted  replacement. With the traditional (non-computer-assisted) knee joint surgery, formerly inserted hardware frequently needs exclusion  to executing the knee surgery. When using the computer-assisted method, this added surgery and hardware removal can be ignored. In short, this surgery is the most technologically progressive accurate method of executing your knee surgery today.

Primary Knee Joint Replacement

Primary Knee Joint Replacement Surgery is a MEDICAL INTERVENTION. This Surgery uses Inserts made from metal, high density polyethylene or ceramic to exchange a diseased or damaged knee joint. The primary process is the PATIENT’s first joint replacement process on a specific joint. Your knee is a pivot joint where the finish of the thigh bone (femur) meets the start of the huge bone in your lower leg (tibia). 

A solid knee has smooth ligament that covers the closures of the femur and tibia. The smooth ligament lets the surfaces of the two bones coast easily as you twist your knee. The muscles and tendons around the knee joint help your weight and help move the joint easily so you can stroll without torment.

The smooth ligament layers can wear out on the finishes of the femur and tibia. At the point when the smooth surfaces become unpleasant, the surfaces resemble sandpaper. Rather than the joint coasting when you move your leg, the bones granulate and you have torment and/or solidness. In this condition, you need to have knee joint replacement surgery.

This degeneration can occur because of assortment of reasons, for example, the accompanying causes:

  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

As  time passes away, knee joint replacement surgeries may fail for many reasons. When this happens, you may have a painful and swollen knee. It may also feel firm or unbalanced, making it problematic to execute your everyday actions. If your knee surgery fails, your surgeon may suggest that you have a second surgery—revision total  replacement. In this process, your surgeon eliminates some or all of the parts of the genuine prosthesis and exchanges them with new ones.

Although both process have the same objective—to release pain and recover function—revision surgery is different . It is a extended, more difficult process that needs more planning, and expertise in implantations and tools to attain a good result.

There are many types of revision surgery. In some cases, only one implantation or element of the prosthesis has to be revised or repeated. Other times, all three elements—femoral, tibial, and patellar—require to detach or exchanged and the bone around the knee requires to be recreated with augments (metal pieces that substitute for missing bone) or bone graft.

Injury to the bone may make it hard for the surgeon to use standard total knee implantation for revision knee joint replacement. In most cases, he or she will use good implantations with longer, thicker stems that fit  in- depth inside the bone for extra support.

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 may take up to 12 months to fully get well. Mostly people will feel relaxed going back to job and continuing some of their normal doings three to six months after the knee joint replacement treatment (this may not include exercise or other physical activities).


What is the success rate of revision knee joint replacement?

In 85% to 90% of people who have a total knee joint replacement surgery, the knee implantations performed will last about 15 to 20 years. This means that some patients who have a knee joint replacement surgery at a earlier age may eventually required a second surgey to clean the bone surfaces and refix the implantations.
