With age, we all experience pain in our body. One such common pain is knee pain. Multiple studies suggest that Indians and women are more susceptible to knee pain. For many such individuals with chronic pain, a Total Knee Replacement (TKR) surgery becomes the only beacon of hope and a second chance to have an improved quality of life. However, amidst the anticipation of improved quality of life lies a critical decision: the wise choice of correct knee implant.
Before understanding implants, let’s take a moment to understand
Total Knee Replacement Surgery
A Total Knee Replacement surgery becomes necessary when the knee joint sustains damage, resulting in exhausting and intense pain. This severe knee pain can stem from various underlying causes, including:
– Osteoarthritis: This is one of the most common cause of knee pain. This is common in the aging population and is characterized by the ‘wear and tear’ of the joints.
– Rheumatoid Arthritis: This is an autoimmune disorder where the body’s immune system attacks its own tissues, including the joints, leading to inflammation and damage
– Knee Joint Injury: This includes traumatic incidents or injuries to the knee joint and its surrounding structures which can cause significant damage
– Late-Stage Bone Cancer
The knee joint functions similar to a door hinge, facilitating limited motion. It comprises of bones, ligaments, muscles, cartilage, and other soft tissues. The bones include Femur (thigh bone), Tibia (shin bone), and Patella (knee cap). Together, these components ensure stability and the smooth functioning of the joint, enabling activities essential for daily life.
A Total Knee Replacement surgery is aimed at lessening the pain and restoring functionality to a compromised knee joint. During this surgery, the damaged portions of the knee are replaced with specialized implants, effectively restoring the joint function. These implants typically comprise four key components:
– Femoral Component: This component replaces the damaged portion of the Femur (thigh bone)
– Plastic Spacer: This is positioned between the femoral and tibial components and serves as a cushion to minimize friction and wear
– Tibial Component: This component replaces the damaged portion of the Tibia (shin bone)
– Patellar Component: This replaces the worn or damaged Patella (knee cap)
Together, these components work harmoniously to recreate the motion of the knee joint, enabling patients to experience reduced pain and improved mobility following surgery.
So, how to make sure you are making the right choice?
With a plethora of knee implants available in the market, selecting the most suitable option can be a confusing task. To make informed decisions, it’s crucial to understand the intricacies of these implants.
A knee implant serves as a substitute for the natural knee joint, yet many traditional designs are unable to replicate its intricate motions as they rely on a simplistic hinge-like mechanism. However, the OURO EXCEL Medial Pivot Knee (MPK) implant stands out as an exception.
Distinguished by its innovative design, the OURO EXCEL Medial Pivot Knee implant is engineered with the singular objective of ensuring patients achieve a high level of satisfaction post-total knee replacement. Its unique construction closely mimics the physiological kinematics and anatomical structure of the native knee joint, aiming to replicate its natural movement patterns.
In a natural knee joint, the inner side plays a pivotal role in providing stability during everyday activities such as bending or walking. Thus, it bears a substantial portion of the strain. By prioritizing stability on the inner side, the OURO EXCEL Medial Pivot Knee effectively imitates this crucial function. This emphasis on stability, coupled with three distinct design advancements, enables the implant to offer patients a truly ‘natural knee’ experience.
But, how exactly OURO EXCEL Medial Pivot Knee provides a ‘Natural Knee’ experience?
The OURO EXCEL Medial Pivot Knee implant sets itself apart with a host of innovative features aimed at enhancing stability, functionality, and long-term patient satisfaction.
Femoral Component: Has a single-radius design which minimizes instability, providing patients with confidence in their movements.
Anatomic Insert: Has a deep groove that accommodates the natural shape of bones, reducing pressure on the knee joint and unexpected knee joint motion.
Tibial Component: Has a 3-degree posterior slope, dove-tail locking mechanism, and peripheral rim, which delivers maximum rotational stability.
The Gold* coating on the OURO EXCEL Medial Pivot Knee enhances body safety and offers allergy protection.
Swiss precision is used in its creation to guarantee dependability and a precise fit.
Vitamin E polyethylene, which has a better oxidative resistance, is used to make the components. As a result, there is reduced bone loss and infection.
All of these characteristics increase patient satisfaction following surgery and give the implant overall long-term stability.
Multiple studies** have demonstrated the efficacy of the Medial Pivot Knee implant, with patients experiencing significant improvements in the Oxford Knee Score (OKS), a key measure of knee pain and function. Post-surgery, OKS scores soared from 19.5 to 41.2, indicating remarkable enhancements in patient outcomes. Furthermore, the average maximum active movement post-surgery reached 124°, highlighting the implant’s ability to restore mobility and function effectively. These studies indicate that there are minimal chances of patients requiring a repeat surgery after a Medial Pivot Knee surgery.
The OURO EXCEL Medial Pivot Knee implant represents a beacon of innovation, providing more than just relief from knee pain. It offers patients a pathway to restored mobility, stability, and overall satisfaction post-surgery. From regaining confidence to rediscovering independence, the journey post-surgery is significantly catalyzed by OURO EXCEL Medial Pivot Knee.
Given the significance of Total Knee Replacement surgery, it is crucial to make the decision thoughtfully, in consultation with a qualified healthcare professional, ensuring personalized care and optimal outcomes.
