Was knee joint replacement surgery recommended by your doctor? Some important information are summarized here about preparation for the intervention, process of the surgery and details of the postoperative care. Knee joint replacement surgery is currently one of the most advanced interventions in medicine, it helps treating knee joint problems, and may significantly improve quality of life and mobility.
Knee joint replacement surgery
Structure of the knee
The knee is one of the biggest and most complex joint of the body, which involves three main bones: thighbone (femur), shin bone (tibia) and kneecap (patella). These bones are supported and stabilised by strong ligaments. The cartilage covering the knee joint allows its smooth movement and decreases friction.
About the knee joint replacement surgery
Knee joint replacement surgery is an orthopaedic intervention to treat knee joint wear and pain. During the intervention, an artificial knee joint (a prosthesis) is implanted to replace the injured parts of the joint.
When may this kind of surgery be necessary?
Knee joint wear: Wear of the knee joint causing pain and limited mobility.
Ligament rupture: Previous injuries, such as cruciate ligament rupture may cause instability and pain.
Sport injuries: Previous sport injuries, which can affect the condition of the knee in the long term.
Axis deformity: Long-term axis deformity, such as bow legs causes knee wear and pain.
Answers from the doctor – What do knee joint replacement surgeries look like?
How are knee joint replacement surgeries performed?
During preoperative consultation, the doctor reviews the X-ray or MRI images brought by the patient to assess the condition of the knee. Afterwards, the doctor explains the course, advantages and risks of the surgery, and answers any questions the patient may have.
01
During the preparation for surgery, the patient participates in a consultation with the anaesthesiologist, during which the anaesthesiologist decides if the surgery will be performed under general anaesthesia or local anaesthesia.
02
The surgeon makes small incisions above the kneecap to access the joint. Sparing the muscles, the kneecap is slid to one side.
03
The worn bone surfaces are removed and prepared for implantation of the prosthesis. A thin, 6-8-mm bone layer is removed from the surface of the thighbone and the shin bone.
04
The prosthesis is attached to the appropriate parts of the thighbone and the shin bone using bone cement. The prosthesis consists of metal and plastic components, which provide smooth movement and stability.
05
After implantation of the prosthesis, the surgeon tests movement of the joint to provide proper alignment and stability. Balance is important both with extended and bent knee. Afterwards, the surgeon closes the incision and applies sterile dressing onto the wound.
06
Postoperatively, the patient remains under monitoring at the clinic. Even on the day of the surgery (if the intervention was performed in the morning; or the next morning, if it was in the afternoon), the patient is able to sit on the side of the bed, stand up and start rehabilitation exercises with the help of a physiotherapist. The patients need to continue their physiotherapy and rehabilitation exercises at home to provide complete recovery and regain mobility, besides attending regular follow-ups.

More information
What are the most common causes of knee-related complaints?
1. Knee joint wear (arthrosis): Knee joint wear is one of the most common causes of knee pain. Gradual thinning and wear of the cartilage and the resulting rubbing of the bones to each other cause pain and inflammation. Knee joint wear often develops as a result of axis deformity (bow legs).
2. Ligament rupture: Previous injuries, such as cruciate ligament rupture causes instability and pain in the joint. These injuries often develop as a result of sport injuries or traumas, and have long-term consequences.
3. Previous sport injuries: Sport injuries, such as injury of the knee ligaments or meniscus can cause knee joint wear and pain, if left untreated.
4. Axis deformity: Chronic axis deformity, such as bow legs (O legs) or knock knees (X legs) exert uneven load on the knee joint, and cause wear and pain in the long term.
5. Swelling and oedema: Limited joint movement and swelling are often the natural reaction to knee joint wear, and can lead to oedema. This excess fluid is a natural reaction of the worn joint to inflammation and pain.
Surgery as a solution?
Before any orthopaedic intervention, it is important to consider alternative, non-surgical solutions. These approaches, such as medicinal treatments, physiotherapy or injection therapy can be effective in several cases in improvement of symptoms and treatment of joint problems.
However, when these methods do not provide appropriate results, and the patient has severe pain and limited ability to move, orthopaedic surgery can be the only effective solution. A lot of people are afraid of this surgery, it is important to know that these interventions can result in significant improvement in quality of life and pain relief. Therefore, people with severe joint problems that cannot be resolved appropriately with other treatments, should consider orthopaedic surgery.
How to prepare for surgery?
Before a knee surgery, our specialists will provide detailed information on how you should prepare for the intervention. It may include restrictions in diet, modification in medicines, and arrival on fasting state on the day of the operation. It is important to follow the instructions of the doctor to contribute to the success of the intervention and your quicker recovery.
What are the risks of this surgery?
Knee and thighbone surgeries may involve the following risks:
- unsuccessful correction
- thrombosis
- scarring in the operated area
- infection of the operated area (with 1% frequency)
In case any complications develop during/after the surgery, and it is necessary, care will be provided at Szent-Györgyi Albert Medical Center – Emergency Care Unit, for a fee.
What happens after the surgery?
Following these kind of surgeries, generally there is a postoperative healing process that includes paint relief, wound care, rehabilitation (such as physiotherapy), and based on the type of the condition and nature of the surgery, regular follow-up examinations to follow the results and help full recovery.
