Disadvantages of Knee Replacement Surgery

Disadvantages of Knee Replacement Surgery

Knee replacement surgery has been one of the most popular treatment methods in the world and in our country for over 30 years. There is no serious risk or harm in general. However, as with any surgery and surgery, there are some risks involved in knee replacement surgery. In order to avoid a possible risk after surgery, it is necessary to carry out the necessary examinations and research prior to surgery and to take care of the choice of the doctor and the institution to perform the surgery.

 

Possible Risks In Knee Replacement Surgery

  • Implant fracture: Of course, the reasons for this condition include the material used and the person performing the surgery. But the biggest cause of this condition is excessive weight, movements and activities that force the knee region.
  • Bone Abrasion: After knee replacement surgery, abrasions may occur in the bones around the prosthesis. This can lead to a re-function-loss of the knee and pain.
  • Infection: As with any surgery, a non-sterile sloppy environment, or for a variety of reasons, the surgical region may become infected.
  • Blood Coagulation: Knee replacement surgery directly affects the veins of the legs. This may occur if the circulation of blood in the veins in the legs is disrupted after surgery. For this reason, the leg should be moved and blood circulation should be accelerated by doing exercises with certain tempos after surgery.
  • Allergic Reactions: In rare cases, the body of some patients may have an allergic reaction to the implant metal applied to the knee area. The easiest way to prevent this is to determine whether a patient has this type of allergy prior to a knee replacement surgery.

 

In Which Circumstances Should Knee Replacement Surgery Not Be Performed?

  • As with any surgery, there are situations where knee replacement surgery is inconvenient and risky, and these situations can be listed as follows:
  • If the bones of the patient are weak or the patient has osteoporosis that can not carry the prosthesis.
  • If there is an active infection in the knee area that has not yet been healed, or if there has been a serious infection before.
  • If the veins in the knees have been damaged by various causes.
  • If the muscles in the region have lost function or are damaged.

If the patient has insufficient bone development, etc.

What Is a Knee Replacement?

What Is a Knee Replacement? After the cartilage joint bones in the knees are deformed and unable to function due to various reasons, the cartilage joint bones in the knees are removed and replaced with knee prosthetics. The purpose of this surgery is to eliminate movement restriction and pain of the individual by simulating the current functioning with the implanted prosthetics.

 

In Which Cases Is Knee Replacement Surgery Considered Necessary?

Knee replacement surgery is performed for individuals who have arthritis in the knee joints for a variety of reasons and experience pain and movement restrictions as a result. There are major reasons for deformation and calcification of the knee joints;

  • Various inflammatory diseases
  • Excess weight
  • Fractures and cracks in joints
  • Advanced rheumatism disorders
  • Lesion formations
  • Meniscus ruptures and injuries, etc.

The reasons mentioned above cause damage to the knee joints and the knee joints are largely unable to perform their functions. The pain that occurs as a result of these deformities can cause people to experience extreme pain even when they are stable at advanced levels of the disease. In cases of infection, if there is still infection in the region, a knee replacement surgery can not be performed unless the infection is completely healed.

Process After Knee Replacement Surgery

  • The hospitalization process for patients after surgery is an average of one week.
  • The patient may perform movements related to basic individual needs, such as walking, sitting and going to the toilet no later than 2 days after surgery.
  • The exercises recommended by the doctor should be continued on a regular basis after the stitches have been removed at the end of the 15th day and after surgery.
  • Depending on the operation, the formation of turgescency in the knee region continues for up to 5 months. However, normal mobility can generally be achieved at the end of 1-1, 5 months.

The life span of the prosthesis used in knee replacement surgery has increased to 20 years in parallel with today’s technologies. On the other hand, there are many different factors and reasons that affect the life span of knee prostheses;

 

  • First of all, the institution where the surgery is performed, the environment and the doctor who performs the surgery have a very large share of the life-span of the prosthesis.
  • In addition to these, the patient has the largest share to determine the life-span of the prosthesis. The age , sex, weight and lifestyle of the patient are determining factors in this regard. After surgery , the patient should pay close attention to weight and exercise and avoid challenging movements that may lead to re-deformation of the knees.
