Everything You Need To Know About Primary TKR

TKR or total knee replacement is a surgical procedure during which the damaged knee joint is replaced by an artificial joint or by the prosthesis. Forgetting a TKR done the primary indication is pain which usually gets followed by limitations of the functionality of the patients. To get a primary TKR, the condition of the knee should be pretty serious as this is the last resort after all the medicine and physiotherapy. Before you get primary TKR done for unbearable knee pain, there are some of the things you need to know about it.

What is the Primary TKR?

Arthritis of the knee is the disease for which primary TKR is done. In this condition, the knee experiences a loss of the articular cartilage of tibia, femur or patella. In the x-ray, it is observed as a gap between 2 of the ends of the bone. People with arthritis often experience stiffness in the knee region as there is a loss of the gliding surface and it might even restrict the movement. Normally walking for a long distance or standing for a long time can make arthritis pain worse. The three types of arthritis that commonly occurs in the knee are osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis. While there is no specific age, it normally occurs at an age greater than 60 years. Thus, advance to a doctor’s chamber, to be precise, orthopaedic when you experience and have difficulty in walking.

Signs and symptoms of Primary TKR

Pain – while the pain can begin suddenly it will increase gradually. Some people feel the pain when the seasons change; other people feel the pain even when lying down or sitting.

Inflammation – the knee may swell after it has been inactive for a long time. Tenderness of the knee is also commonly observed in this disease.

Weakness- you may observe weakness in the knee so that your knees lock often and the joint structure becomes unstable. These symptoms might come and go or even stay permanently.

Grinding – do not get scared if you feel a sensation of grinding as you move your knees. Also, nothing to be afraid of the popping and cracking sounds, these happen as you have already lost the smooth cartilage.

Motion – it becomes increasingly difficult for people suffering from arthritis to move their legs as the movements almost become impossible. The motion also gets restricted.

Treatment of Primary TKR

Based on the severity of arthritis and the age of the patient the diagnosis is chosen. However, the most common method of treating it is performing primary TKR.

Primary TKR has evolved over the years, and now there has been a lot of improvement in the surgical techniques and the implants. Thus, it is the most widely used orthopaedic procedure currently. Primary TKR is classified as a major operation and can only be chosen as a last resort. In the process of primary TKR, the damaged knee gets replaced by a prosthesis or an artificial knee joint. TKR involves three major types of replacement prosthesis; they are the non constrained, semi-constrained and the constrained ones.

Some of the risks involved with performing primary TKR are that there might be infection, stiffness, loosening, etc. however, it is effective surgery, and the patients of osteoarthritis that undergo this have faced major improvements in pain reduction and movement. There is substantial evidence of primary TKR effectively reducing the pain experienced by the patients so it should be considered by all the people suffering. Primary TKR makes it possible for the aged people to walk and run again freely, without any constraints.
