Having knee replacement surgery is a great way to relieve joint pain. Knee replacement surgery is also called knee arthroplasty. This surgery involves replacing the damaged knee joint with a prosthetic device.
Partially knee replacement
Compared to total knee replacement, partial knee replacement surgery is less invasive and usually requires a smaller incision. In addition, the procedure is associated with less pain and faster recovery. However, patients are generally eligible for this type of surgery only if they have an arthritic injury that has not responded to nonsurgical treatments.
A patient can decide whether or not to undergo partial knee replacement surgery by examining the medical history, including pain, stiffness, and instability of the knee. In addition, an MRI scan or X-ray may be used to determine the extent of the damage.
A patient’s age, level of activity, and weight are factors that can affect eligibility for this surgery. In addition, severe knee damage may require total knee replacement.
Partial knee replacement surgery is generally a minimally invasive procedure, but there are still risks. For example, blood clots, infection, and nerve damage are all potential complications.
Patients may have to be hospitalized for a period of time after the surgery. They may also be asked to stop taking certain medications. Patients who smoke or have certain health conditions may not be eligible for this procedure.
The surgical procedure involves using special instruments to remove damaged cartilage from the knee. A tourniquet may also be used to control bleeding. The surgeon may also use a local anesthetic to numb the area. This reduces postoperative pain and swelling.
The procedure typically takes one to two hours. The patient is usually in the hospital for a day or two, but most patients are able to return home the same day. In addition, patients will undergo physical therapy. During this time, they will learn exercises to strengthen their leg. They may also participate in low-impact sports to avoid excessive wear on the new knee joint.
The recovery process may take several months. Patients will need someone to help them with their daily activities. They should also wear TED stockings for two weeks. They may also be instructed to wear a walker.
Patients should discuss the risks of this surgery with their healthcare provider. The surgical procedure is considered a last resort for many patients.
Disadvantages
Despite its many benefits, there are still some disadvantages of knee replacement surgery. The majority of the complications associated with this operation can be avoided if patients follow certain pre-operative and post-operative steps.
The most important thing to remember during knee replacement surgery is to select an experienced doctor. Your doctor will explain the advantages of the operation and answer any questions you may have.
The procedure is often done under general anesthesia, but some patients may have to receive local anesthesia. Local anesthesia is generally safe but can have some negative effects.
The surgeon will cut a 15-25cm incision at the bottom of the knee. This allows them to expose the knee joint and the thigh bone. The surgeon will also cut and stretch the muscle and ligaments around the joint. This can lead to pain and discomfort.
The surgeon will then insert a flat piece of plastic and a metal stem into the thigh bone. They will also use a thin, flexible telescopic instrument called an arthroscope to examine the knee joint.
The surgeon will also insert a plastic button under the kneecap. This helps stabilize the patient’s body temperature during the procedure.
The surgeon will also use special tourniquets to restrict blood flow in the leg. This can cause nerve damage. It is also possible for the wound to become infected. It may require further surgery to remove the infected tissue.
Patients can have their legs wrapped in an ice pack to help reduce swelling. This will also help to decrease the pain. Patients will also have to avoid contact with water as this can make the incisions wet and increase the risk of infection.
Some patients may have to wear a walking frame for a while after the surgery. This is to ensure proper circulation of blood and avoid blood clots. Patients can usually return to work after six to eight weeks.
Patients with certain medical conditions, such as diabetes, have a higher risk of infection. People with HIV are also at increased risk. People with heavy manual jobs are also at a higher risk.
Recovery time
During the recovery time after knee replacement surgery, the patient can experience pain and swelling. There is also an increased risk of blood clots. The patient must avoid excessive stress on the new joint. However, there are a few things to consider to help speed up the recovery process.
Patients who choose to stay home after surgery can take advantage of a home physical therapy program. These sessions teach the patient how to use crutches and other aids to regain mobility. The patient will also learn exercises that can help increase mobility and strength.
While most patients are advised to stay home for at least a few weeks, some people are able to go home the same day as their operation. This is an important step for people who live alone or who want to avoid the expense of an extended stay at a hospital.
Depending on the patient’s age, occupation, and health, the recovery time after knee replacement surgery can vary from one day to up to three months. It is important to start doing low-impact daily activities around the seven-week mark.
One of the best ways to help the knee recover is to begin physical therapy. The exercises will help the knee regain its full motion and strength. This may include putting full weight on the knee for the first time. The PT may also ask the patient to climb a few steps at a time.
While the recovery time after knee replacement surgery is variable, most patients can resume normal activities within two months. This includes work and household duties. Some patients can even return to a desk job in as little as a week.
During the recovery time after knee replacement surgery, a patient may also be given narcotic pain medication. These medications are used to help the patient feel comfortable during rehabilitation.
Another important part of the recovery time after knee replacement surgery is the use of an assistive device. The use of crutches or a walker can be beneficial for the first several weeks. The patient will also be given a knee brace to help with recovery.
Complications
During total knee replacement surgery, the surgeon removes damaged tissue and replaces it with a metal and plastic prosthesis. This prosthesis is custom-fitted to the patient’s knee. Depending on the type of surgery, it can take between one and three hours.
Patients may be given a general anesthetic and an epidural catheter to numb their knees. During the surgery, the surgeon uses special tourniquets to control blood flow to the leg. They also need to stretch the muscles of the leg. If the muscle is not stretched, it may damage the nerves around the knee joint.
The surgical procedure involves making a 15 to the 25-cm incision in the knee. The surgeon will also apply a tourniquet to reduce blood flow to the knee.
The surgeon uses specialized jigs and instruments to remove bone from bone. Then, he attaches a metal plate and screws to connect the broken bone fragments.
Patients can expect some pain after knee replacement surgery. Patients may need to take painkillers for a few weeks. In addition, patients may need to wear compression stockings to prevent blood clots. Patients may also need to use ice packs during their recovery. Patients may also have to avoid certain fluids, black coffee, and milk.
Patients may have to use a cane or other aid to walk for three to four weeks. Most patients are able to walk without assistive devices by the time they are three months post-surgery.
A nerve block is often used to numb the area around the knee. This may cause some complications. In 2009, a study conducted in The Journal of Arthroplasty found that 1.3 percent of patients had a nerve block complication. These complications can sometimes delay recovery.
Patients may also experience bone fractures. These fractures may occur in the thighbone or kneecap. If this happens, patients need to seek immediate treatment. The fracture may be severe and can result in amputation. Patients may also develop an infection. Infections require treatment with antibiotics. If the infection is not treated, it may cause the prosthetic knee to fail. This may require revision surgery.
Patients may also have a blood transfusion during surgery. Blood clots are a serious complication of knee replacement surgery.
