    What is Knee Implant?

    A knee implant is an artificial prosthetic which is used during knee replacement operations. In knee replacement surgery, the doctor will remove a damaged section of the knee joint and, in place of that, use a knee implant to restore the structure and functionalities of the joint. 

    Components of Knee Replacement   

    Generally, the knee replacement implant is made up of three elements: metal alloys, plastic and ceramic materials. So, these components are:

    • Femoral Components

    This interacts with the lower bones called the femoral (thigh bone). The design of the bone is usually altered with grooves to ensure that the knee cap is able to move easily and assist in the bending and straightening movements.

    • Patellar Part

    This component takes the place of the regular patellar bone. It is usually constructed of plastic, and its back is shaped like a dome, allowing for the normal movement of knee joints.

    • Component of the Tibia

    This component articulates with the top of the tibia, i.e. it is the bones of the shin. It is typically composed of a cushion made of polyethene and a flat metal platform. In certain situations, when needed, the metal component may be inserted into the tibia for extra stability.

    Different Types of Knee Implants

    There are various types of knee implant available which is used for minimally invasive knee surgery. The leading difference between these implants is whether the implant will change the complete joint or part of it. Also, there are various elements like stability of ligament, misalignment of the knocked knee, bow legs, and situation of bones and muscles, etc., that will decide the suitable type of knee implants. Here are some of the common types of knee implants suggested by the best orthopedic doctor in Delhi.

    1. Implants Based on Material

    Generally, the most common type of implant is made of ceramic, plastic or metal alloys. 

    • Ceramic Implants

    This implant will provide a natural feel to the knee. In comparison to metal and ceramic joints, it is less likely to wear and tear. But, if the ceramic implant is struck forcefully, then there is the probability that it will break. In that case, emergency surgery is required to replace the damaged ceramic part. 

    • Metal Alloy Implant

    It is built by using Metals like Titanium and Cobalt Chromium. These implants are durable and biocompatible. But, if you are allergic to metals, then you should avoid this implant.

    • Plastic Implant

    Implants made of plastic can be an excellent option when you’re looking for the most affordable implants. It works best when paired in conjunction with components made of metal. However, they can trigger an immune response that can cause the surgery to fail.

    1. Implants Based on Design
    • Mobile Bearing Implant

    This type of implant design allows for limited rotation of the knee joint. It has a groove that will fix with the tibial element, which helps in twisting. This type of design is best for youngsters and elders who are less physically active.  

    • Fixed Bearing Implant

    The majority of knee implants are fixed-bearing. They need to be more flexible, and it is best suited for patients with chronic illnesses who do not lead active lifestyles. A lot of movement could cause wear and tear because the implants aren’t as flexible.

    1. Implants Based on Affixing Material

    The implants which are attached to the knee are using two different techniques:

    • Cemented Joint

    In the cemented joint techniques, the implants are fixed with the knee bone by using quick-drying cement. However, there is a chance of breaking this cement, which can lead to the failure of surgery. 

    • Non – Cemented Joint

    When the procedure is done by using a joint that is not cemented, it allows room for the bone’s natural growth to grow. Implants are firmly anchored within the bone. It’s ideal for young people who have bones of good quality and are growing rapidly.

    Conclusion

    Choose the best knee replacement implant which has a good track record and is suitable to the situation. So, if you are in a dilemma about which option is better, then consult with the best orthopedic doctor in Delhi who has successful years of experience in working. A good implant restores normal function to the knee and lasts for a lifetime.
