What is the success rate of knee replacement

Many patients do not pay attention to the existence of arthritis in the early stages of the disease, which leads to more and more severe arthritis and the occurrence of joint deformation, joint nodules and other pathological conditions. Once joint deformation occurs, the patient will experience more serious movement disorders, and at this time joint replacement surgery is needed to fundamentally treat arthritis. However, before undergoing knee replacement surgery, patients need to understand the success rate of knee replacement surgery.

Is knee replacement surgery successful?

In the late stage of arthritis, when severe joint deformities and movement disorders occur or when the joint structure changes due to various reasons, it is unwise to use drug treatment alone, because drugs can only partially relieve pain symptoms but cannot change changes in joint structure. Artificial joint replacement can achieve the purpose of relieving pain, correcting deformities, and improving joint function. An artificial joint is an artificial organ designed to save a joint that has lost its function. Among various artificial organs, the therapeutic effect of artificial joints is particularly good. Generally speaking, the design life of artificial joints is 50 years, and 90% of them can last for more than 20 years.

Arthritis can occur in any joint of the body, most commonly in the hip, knee, and finger joints. The knee joint is the largest, heaviest and most weight-bearing joint in the human body and is also the joint most susceptible to arthritis.

When many patients hear that they have arthritis, they ask whether they can be treated conservatively or whether they need surgery.

This cannot be generalized, and the most appropriate treatment method needs to be selected according to the condition.

In the early stages of the disease, knee pain worsens when going up and down stairs and can be relieved on flat ground. Knee X-ray examination shows slight narrowing of the joint space and mild bone hyperplasia around the joint. Non-surgical treatment can be chosen at this time. It includes (1) lifestyle intervention: losing weight, keeping warm, and avoiding exercises that damage joints; (2) oral anti-inflammatory and analgesic drugs, such as celecoxib and diclofenac enteric-coated tablets; (3) intra-articular injection of drugs, such as sodium hyaluronate injection (Sipet or Alge), etc.

When the disease progresses and lifestyle changes and drug treatments are ineffective, surgical treatment should be considered. Knee arthroscopy is an option for surgery.

If the disease develops to the late stage, the joints continue to be painful and deformed, X-rays show that the joint space has disappeared, and the patient cannot walk, which seriously affects the quality of life. At this time, knee replacement surgery should be considered. If the unicompartmental joint is affected, unicompartmental knee replacement surgery can be used. If the entire joint is affected, total knee resurfacing surgery can be considered. By removing the diseased cartilage and installing an artificial joint to replace the cartilage, the purpose of relieving pain, correcting deformities and improving joint mobility can be achieved.
