The Benefits of Knee Replacement Surgery: Why It’s a Good Option
For the surgical treatment of knee osteoarthritis, the most routine clinical treatment is knee replacement surgery, which brings good news to patients with end-stage knee osteoarthritis. This operation’s pain relief effect is certain; knee prostheses’ survival rate is very high, and the 10-year survival rate can reach 98%; the total knee replacement technology is becoming increasingly mature and more procedural. All of the above has led to the continuous expansion of the indications for clinical knee replacement surgery; after patients with knee joint OA, due to the lack of other treatment methods in addition to conservative treatment in most hospital orthopedics departments, the patient’s choice is only “either directly replace the joint, or wait.” Change your joints.”
This operation can effectively relieve pain and improve joint function, but at least 20% of patients are not satisfied with the function after surgery .
Patients under 60 accounts for 15% of the population receiving knee replacement surgery, and there is an increasing trend. Compared with older patients, younger patients had higher dissatisfaction rates after surgery , lower prosthetic survival rates, and higher revision rates. A multi-center study included 661 patients under 60 who underwent this treatment. The results showed that the incidence of intractable pain and stiffness after surgery was 33% and 41%, respectively. And 50% could not return to sports and leisure. Activity. In addition, young patients also have a longer life expectancy, greater activity, higher expectations for surgery, and need one or more surgical revisions.
Therefore, in addition to “knee replacement,” more attention should be paid to “keep preservation” in the treatment strategy for young patients. The ideal knee-preserving treatment can effectively relieve pain, improve joint function, delay or stop cartilage degeneration. Improve the quality of life, and regenerate damaged cartilage if possible. This article follows the concept of individualized and step-by-step treatment. It reviews the progress of knee-sparing treatment for young patients, aiming to provide a reference for clinical treatment.
However, the goal of knee replacement surgery is functional reconstruction. Through the replacement of the prosthesis, all knee joints can made into a unified line of force, angle, backward tilt. And balance so that all people’s soft tissues can adapt to the function of the prosthesis; at the same time. The cruciate ligament resected during the operation, and the collateral ligament released. The cruciate ligament plays a very important role in providing different flexibility and stability in knee flexion, active movement, passive movement, weight-bearing state, and non-weight-bearing state. Moreover, there are proprioceptors in the cruciate ligament, which can always let us Feel the state of the knee joint. No two people in the world have the same cruciate ligaments.
It sacrifices the cruciate ligament and loses the functions mentioned above. After surgery, no one feels that the knee prosthesis is their joint because the inherent kinematics and proprioception lost. Although major manufacturers have been upgrading total knee prostheses in recent years. The function of the prosthesis and patient satisfaction have not improved. The reason is that the patient allowed to adapt to the movement of the prosthesis rather than the prosthesis. Soft tissue conditions. Therefore, some say this surgery is a kind of “amputation in the joint.”
