Partial knee replacement is a surgical intervention in which only the damaged and damaged part of the knee is replaced, leaving the cartilage, meniscus and ligaments intact. It is performed by replacing the inner or outer part of the knee or the kneecap. Compared to full knee replacements, it is possible to have a faster healing process, a natural feeling and comfortable knee movements.
Damage to the joints can cause pain and restriction of movement in the future. Partial knee replacement is usually performed on middle-aged or elderly patients.
Even if the knee problems are in a partial area, they may prevent the person from performing some movements. The person may experience severe pain when climbing stairs, sitting on the knee and getting up. With partial knee replacement surgery, the person can continue their normal life without pain. There are 3 main parts that make up the knee joint. Any wear condition (arthrosis / osteoarthritis) can develop in these parts of the knee consisting of the inner, outer and kneecap. Generally, arthrosis is more common in the inner part of the knee and less common in other parts. The prosthesis suitable for the person is determined according to the age and weight of the person after the X-ray images and MRI reports of the region are checked by the doctor.
How is Partial Knee Replacement Surgery Performed?
The person does not need to be hospitalized during the examinations before the surgery. A drug (anesthesia) is given to prevent pain before surgery. There are two types of anesthesia. General anesthesia or regional anesthesia is applied in this intervention. When general anesthesia is applied, the person is unconscious and does not feel pain. Under regional anesthesia, the lower back is completely numb and relaxing medication may be given. During the intervention, an incision of approximately 7.5 cm to 13 cm in length is made on the knee. The surgeon then examines the knee joints. The damaged bone and tissue inside the knee is removed and replaced with a piece of plastic or metal. The part is glued to the implanted area and the wound is closed.
Who Can Have Partial Knee Replacement Surgery?
In order for this intervention to be performed on a person, the wear in the joints should only be in a limited part of the knee. It is generally applied to middle-aged and elderly patients. The ligaments in the knee of the person should not be damaged and there should be no restriction in knee movements.
Is Partial Knee Replacement Suitable for Me?
Its suitability depends on the results of the examination to be performed by the doctor, such as X-ray images. As a result of these examinations, it is determined what the problem in the knee is and how much wear is in which area. If there is pain and wear in only a limited area of the knee, this intervention may become appropriate. However, it varies depending on the method the doctor will apply on the examinations performed by the doctor.
Who is not suitable for partial knee replacement?
Partial knee replacement application differs from person to person and is not a procedure that can be applied to everyone. The suitability of the person is very important in terms of functional results and long use. This procedure is not recommended in cases such as overweight problems, calcification spreading to most parts of the knee, severe deformity, and obstacles in joint movements.
How is Recovery After Partial Knee Replacement Surgery?
The recovery process after surgery progresses very quickly. The healing process varies from person to person. People can usually walk without a walker and support within 3-4 weeks after surgery. Physical therapy can be seen after surgery. The person can do most of the exercise types including walking, swimming, cycling, tennis and golf. However, jogging should not be done before full recovery is seen. In addition, postoperative activities should be done according to the doctor's control.
