when is knee replacement required?

product1

The decision to have total knee replacement surgery is usually made cooperatively by you, your family, your family physician, and your orthopaedic surgeon. Your physician may first refer you to an orthopaedic surgeon for a thorough evaluation to determine if you might benefit from this surgery. There are several reasons why your doctor may recommend knee replacement surgery. You might be recommended to undergo a knee replacement if you have:

1) Severe knee pain or stiffness that limits everyday activities, including walking, climbing stairs, and getting in and out of chairs. You may find it hard to walk more than a few blocks without significant pain and you may need to use a cane or walker. 2) Moderate or severe knee pain while resting, either during the day or at night. 3) Chronic knee inflammation and swelling that does not improve with rest or medications. 4) Knee deformity — a bowing in or out of your knee. 5) Failure to substantially improve your condition with other treatments such as antiinflammatory medications, cortisone injections, lubricating injections, physical therapy, or other surgeries. There are no absolute age or weight restrictions for total knee replacement surgery. Recommendations for surgery are based on a patient’s pain and disability, not age. Most patients who undergo knee replacement are aged 50 to 80, but orthopaedic surgeons evaluate patients individually.

Total knee replacements have been performed successfully at all ages in patients with degenerative arthritis. An evaluation with an orthopaedic surgeon consists of several components: A medical history: Your orthopaedic surgeon will gather information about your general health and ask you about the extent of your knee pain and your ability to function. A physical examination: This will assess knee motion, stability, strength, and overall leg alignment. X-rays: These images help to determine the extent of damage and deformity in your knee. Other tests: Sometimes, blood tests, or advanced imaging such as a magnetic resonance imaging (MRI) scan, may be needed to accurately determine the condition of the bone and soft tissues of your knee. Your orthopaedic surgeon will review the results of your evaluation with you and discuss whether total knee replacement is absolutely required to relieve your pain and improve your function. Other treatment options — including medications, injections, physical therapy, or other types of surgery — will also be considered and discussed.

What is knee replacement

product1

“The knee is human body’s largest joint and their healthy maintenance is required to perform most of everyday activities, easily. The knee is made up of the lower end of the thighbone (femur), the upper end of the shinbone (tibia), and the kneecap (patella). The ends of these three bones where they meet are covered with articular cartilage, a smooth substance that protects the bones and enables them to move easily. The menisci are C-shaped wedges located between the femur and tibia. These act as “”shock absorbers”” that cushion the joint. Large ligaments hold the femur and tibia together and provide stability whereas, the long thigh muscles provide strength to the knee. All remaining surfaces of the knee are covered by a thin lining called the synovial membrane. This membrane releases a fluid that lubricates the cartilage, reducing friction to nearly zero in a healthy knee. Normally, all of these components work in harmony. But disease or injury can disrupt this harmony, resulting in pain, muscle weakness, and reduced function.

benefit

The most common disease responsible for disrupting the harmony and causing chronic knee pain and disability is arthritis. Although there are many types of arthritis, mostly knee pain is caused by just three types: osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis. Osteoarthritis is an age-related “”wear and tear”” type of arthritis. It usually occurs in people 50 years of age and older, but may occur in younger people, too. In this type of arthritis, the cartilage that cushions the bones of the knee softens and wears away. The bones then rub against one another, causing knee pain and stiffness. Rheumatoid arthritis is a disease in which the synovial membrane that surrounds the joint becomes inflamed and thickened. This chronic inflammation can damage the cartilage and eventually cause cartilage loss, pain, and stiffness. Rheumatoid arthritis is the most common form of a group of disorders termed “”inflammatory arthritis.””

Post-traumatic arthritis is a type of arthritis that can follow a serious knee injury. Fractures of the bones surrounding the knee or tears of the knee ligaments may damage the articular cartilage over time, leading to knee pain and limiting knee function. Knee replacement involves the removal of your damaged knee joint (due to arthritis or injury) and replacing it with an artificial joint. This is a major surgical procedure requiring hospital admission for 2 to 3 days. A knee replacement might be more accurately termed as knee “”resurfacing”” because only the surface of the bones are actually replaced. There are four basic steps to a knee replacement procedure. 1) Preparation of bones: First of all, the damaged surfaces of the cartilage at the ends of the thighbone and the shinbone are removed along with a small portion of bone lying beneath the surface. 2) Positioning of the artificial implant: The cartilage and the bone which have been taken out are now replaced with artificial metallic components reforming. These artificial components can either be glued to the joint’s surface using a cement or simply “”press-fit”” into the bone. 3) Resurfacing the kneecap: This step involves the cutting of the inner surface of the kneecap and resurfacing it by using a plastic button. Not all surgeons will resurface the kneecap as per the patient’s condition. and 4) Inserting the spacer: A spacer composed from medical grade plastic is then placed in the middle of the metallic parts for facilitating a friction-free movement.”

How much does it cost to have a bilateral total knee replacement surgery using oxinium implants in India

Related image

The cost of total knee replacement is comparatively lesser in India vs. the western nations. Cost ranges between 2 to 3.5 lakhs for a single TKR while a bilateral TKR costs around 5 to 6 lakhs. However, a single seating bilateral TKR is less costly than bilateral TKR done in separate seatings. However, oxinium implants may cost more 70 to 80 thousand more. Selection of the knee implant type is a vital aspect of TKR. It involves consideration of multiple aspects such as ROM, type of metal alloy composition and most importantly, cost of the implants in a country like India. Durability of the implant is as vital as any other aspects listed above. Average durability of any TKR implant ranges from 15 to 20 years.

Gradually, the implant gets subjected to normal wear and tear due to varied forces and begins to lose its quality and strength. This wear and tear gives rise to metal debris into the joint. Hence, it is vital to select an implant that is highly non-reactive to biological components to prevent any hypersensitive reactions arising from the metal debris. Co-Cr and oxinium alloys are a couple of such highly effective materials. Oxinium alloy is composed of two of the most biologically inert metals known till today. TKR implants composed from oxinium possess excellent resistance against fracture and wear. Hence, they prove to be highly favourable materials to manufacture TKR implants.

Theoretical benefits associated with oxinium implants are as follows: 1) >0.0035% detectable Nickel which leads to reactions. 2) Ceramic coating over metal leading in less wear and tear and resulting into higher durability. 3) No evident bioreactivity and is biocompatible. 4) 20% lighter vs. Co-Cr. However, real-world studies have failed to demonstrate considerable difference in terms of safety and effectiveness between Co-Cr and oxinium implants.

90% of patients are overdue for surgery, which reduce chances of success! Total Knee Replacement

benefit img

If you have already tried every other method to treat your pain and restricted movement of your knee, but still are facing the problem, then you can decide opting for a total knee replacement on the basis of the recommendations made by your family doctor and your orthopedic surgeon. The decision to have total knee replacement surgery should usually be made cooperatively by you, your family, your family physician, and your orthopaedic surgeon. Your physician may first refer you to an orthopaedic surgeon for a thorough evaluation and then determine if you might benefit from this surgery and only post the entire evaluation, your orthopaedic surgeon will recommend whether you should go for a TKR or not. Knee replacement is a safe and effective procedure to relieve pain, correct leg deformity, and help you resume normal activities. Knee replacement surgery was first performed in 1968. Since then, improvements in surgical materials and techniques have greatly increased its safety as well as effectiveness. Total knee replacements are one of the most successful procedures in all of medicine.

The rate of complications post TKR is low. Serious events such as knee joint infection, happens in less than 2% of patients. Major systemic complications such as a MI or stroke have even less than the above stated occurence rate. On the contrary, post a TKR, you will be able to experience regained ability to walk or navigate through staircases without pain as well as ability to walk, swim, bike and hike (light hikes). These recreational activities play a vital role in alleviating some of the unavoidable stress that we experience in our daily lives. Such activities which we call hobbies lend us an escape route to get rid from our boring routine and bring about a happy distraction and help in rejuvenating ourselves. In a way, a TKR can enable you to become independent and enjoy your favourite hobbies which you might have not being able to enjoy due to your knee pain and restricted movement.

Who should have a bilateral total knee replacement?

Who should have a bilateral total knee replacement?

product1

Arthritis is a progressive inflammation disease affecting the joints. It can affect any one joint, or in serious cases, multiple joints could also be affected. When symptoms of arthritis affect your knee or both of the knees, it simply means that your cartilages are getting degraded and a TKR might be helpful for you. However, your doctor will only insist that you go for a total knee replacement, if your knee pain and inflammation are affecting your routine activities and adversely affecting your quality of life. In majority of patients, a TKR is carried out if their age is above 60, as artificial knees tend to get degraded more rapidly in younger patients due to their engagement in higher physical activities. In case your both knees have been affected by severe arthritis, you might be suggested to undergo a double TKR or bilateral TKR.

In case of severe arthritis in both your knees, you could have significant stiffness leading to difficulty even in performing simple tass such as wearing shoes. In such a case, pain would get bad during weight bearing tasks such as walking. However, this procedure is more risky as compared to a single TKR. Hence, a bilateral TKR is normally recommended only in patients who are

1) Physically fit

2) In overall good state of health and

3) self-motivated to get PT and tedious rehabilitation post surgery to regain their lost movement. The ideal patient suited for a bilateral TKR is generally younger, healthy, not overweight and suffering from pain, stiff knees, and restricted mobility. Patients with major deformity in both knees can also be considered for a bilateral TKR as correction of deformities in both knees will facilitate the patient to tread straighter and aid rehabilitation.
