About parts knees

Types of parts knees

To understand better what are parts knees, it is essential to learn the different kinds available. Here are the common types of knee parts:

  • Medial pivot knee

    This type of knee is the most common one. It imitates the natural movement of the knee joint, allowing it to bend and straighten. It has two main points of rotation, which are the medial (inner side) point and the lateral (outer side) point. Think of it like a hinge on a door. When the door opens, it moves around the hinge; the same way, the knee joint moves around its pivot point. With this movement, the knee joint is able to provide stability and flexibility that is needed for different activities like walking, running, and jumping.

  • Knee flexion-extension

    The flexion-extension knee is a type of knee joint that allows movement in only one plane, which is forward and backward. This movement is similar to a hinge, which provides stability and support for the leg during activities such as walking, running, and jumping. The flexion-extension knee is commonly used in prosthetic limbs and orthotic devices, helping individuals regain mobility and improve their quality of life.

  • Condylar knee

    The condylar knee joint is a type of joint found in the human body that allows for movement in two planes, providing more flexibility and adaptability than other joint types. This joint is shaped like a cylinder and fits into a groove, allowing for a rolling motion. This unique movement is similar to a bicycle pedal, providing a smooth and stable motion for activities such as walking, running, and climbing stairs. The condylar knee joint is essential for maintaining balance and stability in the leg, allowing individuals to perform various physical activities.

  • Polycentric knee

    The polycentric knee joint allows for movement in multiple planes, providing greater flexibility and stability than other joint types. This joint is composed of several curved surfaces, allowing for smooth and fluid movement. Picture a set of gears working together; each gear allows a different movement, providing a versatile and adaptable motion for activities such as walking down stairs, running on uneven terrain, and changing direction quickly. The polycentric knee joint is crucial for maintaining balance and stability in the leg, allowing individuals to perform various physical activities with ease.

Scenarios of Knee Parts

  • Sports Injuries

    In the event of a sports injury, a doctor may perform knee surgery to insert artificial knee parts or implants. These implants can be made of metal or plastic and provide the required strength and support to the knee. They are especially useful in cases of severe injury when the cartilage is damaged but the bones remain intact.

  • Knee Replacement

    Knee replacement surgery is usually recommended when an individual suffers from chronic pain due to arthritis or has experienced a significant injury that damages the knee joint. In such cases, partial or total replacement of knee parts may be necessary to restore the functionality of the knee. The surgery involves replacing the damaged tissue with artificial knee parts and implants.

  • Synovial Joint Disease

    Synovial joints are the most common type of joint found in humans. These joints have a fluid-filled cavity that allows the knee bones to move against each other without any friction. However, in the event of a disease such as osteoarthritis, rheumatoid arthritis, or psoriatic arthritis, the synovial fluid may reduce or become toxic, leading to immense pain during movement. Doctors may resort to using artificial knee parts to replace the damaged tissue and bone and restore the synovial joint functionality.

  • Bone Disorders

    Bone disorders such as avascular necrosis can lead to death of bone tissue and may require implantation surgery to save the affected limb. During the implantation surgery, knee parts and implants can be used to replace the dead bone. This not only helps to slow down the spread of the disease but also to restore mobility in affected individuals.

  • Accident Victims

    Victims of accidents often suffer from broken bones or damaged tissue that require immediate medical attention and surgery. In such cases, doctors may perform knee surgery and use knee parts and implants to treat the injury. The artificial parts can be made of metal or plastic and are used to replace the damaged bone or cartilage. Using these parts can help expedite the healing process and reduce the need for more invasive surgery.

How to choose parts knees

When buying replacement parts, it is good to consider various factors to ensure they select a suitable product for their requirements.

The first thing to consider is the compatibility of the parts with the existing equipment or vehicle. Check the make, model, and year of the vehicle or equipment and the original part number if available. Compatible parts are vital for effective operation and safety.

Buyers should also check the quality and construction material of the parts. They should look for parts constructed with durable and high-quality materials like cast iron, stainless steel, and carbon steel. Such materials can withstand heavy loads and harsh conditions and have a longer lifespan.

Another factor to consider is the reputation of the manufacturer or supplier. Read reviews and testimonials from other customers and ask for referrals from trusted sources. A reputable manufacturer or supplier offers quality parts knees and provides excellent customer service.

Business owners should also consider the cost of the parts. While they should look for affordable parts, they should also avoid parts that are too cheap since they may be of low quality. Instead, they should look for parts that fit their budget and are of good quality. They can also request quotes from different suppliers to compare prices. This way, they will get value for their money.

The last thing to consider is the lead time and delivery option. If buying from an overseas supplier, it is essential to know the delivery time to prepare accordingly.

In some cases, businesses may require customized parts. In such situations, they should check if the supplier can provide customized solutions based on their specifications and requirements.
