Breakthrough in Longevity of Artificial Knee Joints: Insights from Taiwan

Breakthroughs in the Longevity of Artificial Knee Joints

On March 23, 90, the Liberty Times reported on an interview with Mr.
Wang Guozhao, the president of Kaohsiung Medical University, mentioning that the lifespan of new artificial joints can reach 20 to 30 years.
Are there hospitals in the northern region that are using this product? Which ones?

Dr. Shi Guozheng reply Orthopedics

The longevity of artificial joints, potentially lasting up to twenty years, depends not only on the quality of the materials but also on factors such as surgical technique, the patient's arthritis condition, overall health, and the presence of other diseases.
Current artificial knee joints have been documented in medical literature for over twenty years.
The claim that new artificial joints can last more than twenty years is plausible, and researchers are actively developing this technology.
However, the materials that have proven to last that long are those that were invented in the past and have been clinically validated through extensive use without failure, which is supported by evidence-based medicine.

Some may question how new materials, which have just been invented and used in a limited number of patients, can be claimed to be durable for such a long time.
Only time can provide the answer.
It is common for newly developed products to be touted as the best upon their release; without such claims, they may not attract attention.
Therefore, it is prudent to exercise caution when considering the use of a new product.
Being the first to try it carries risks, whether the outcome is positive or negative.
Why not wait for more substantial evidence to confirm its safety, efficacy, and suitability for the Taiwanese population? There will still be time to adopt it later.

More Info

The longevity of artificial knee joints has been a significant focus in orthopedic surgery, particularly with advancements in materials and surgical techniques. According to recent insights from Taiwan, particularly from the interview with Dr. Wang Guozhao, the president of Kaohsiung Medical University, new artificial joints are reported to have a lifespan of 20 to 30 years. This is a substantial improvement compared to older models, which often required replacement after 10 to 15 years.

In Taiwan, several hospitals are equipped to perform knee replacement surgeries using these advanced artificial joints. Notably, major medical centers in northern Taiwan, such as National Taiwan University Hospital and Taipei Veterans General Hospital, are known for their orthopedic departments and are likely to offer these newer knee joint replacements. These institutions are at the forefront of orthopedic innovations and often participate in clinical trials for new medical technologies, including artificial joints.

The longevity of artificial knee joints is influenced by various factors, including the patient's age, weight, activity level, and adherence to post-operative rehabilitation protocols. The materials used in the construction of these joints have evolved, with newer models utilizing advanced polymers and metal alloys that enhance durability and reduce wear over time. Additionally, the surgical techniques have improved, allowing for better alignment and positioning of the joint, which can significantly affect its longevity.

It is essential for patients considering knee replacement surgery to consult with their orthopedic surgeon about the specific types of artificial joints available and their expected lifespan. Surgeons can provide personalized recommendations based on the patient's medical history, lifestyle, and specific needs.
Furthermore, patients should be aware that while advancements in artificial joint technology have improved outcomes, the success of the surgery also heavily relies on proper post-operative care. Engaging in physical therapy, maintaining a healthy weight, and avoiding high-impact activities can contribute to the longevity of the artificial joint.

In summary, the advancements in artificial knee joints in Taiwan are promising, with reports indicating a lifespan of 20 to 30 years for newer models. Patients in northern Taiwan can access these innovations at major medical centers, where they can receive comprehensive care tailored to their individual needs. As always, thorough discussions with healthcare providers will help ensure the best possible outcomes for those considering knee replacement surgery.
