What is Knee Replacement?

Knee replacement is a surgical procedure where a damaged or worn-out knee joint is replaced with an artificial one, usually made of metal and plastic components. This surgery is often recommended for people who suffer from severe knee pain or stiffness due to conditions like arthritis, injuries, or other degenerative diseases. The main goal of arthroplasty is to relieve pain, improve mobility, and help patients return to their daily activities with greater ease and comfort.

Knee Replacement Recovery Timeline

How long will the recovery take?


Recovery from knee replacement surgery generally takes about 6 to 12 weeks, though this can vary depending on the individual’s overall health and how well they follow post-surgery care instructions.

How long will they need to stay in Turkey?


Patients usually stay in Turkey for about 10 to 14 days after the surgery. This allows enough time for initial recovery, follow-up appointments, and to ensure there are no complications before traveling back home.

When can the patient return to work?


Most patients can return to light work duties within 4 to 6 weeks after surgery. If the job requires heavy lifting or extensive physical activity, it might take up to 3 months or more before the patient can return to work safely.

When can the patient return to exercise?


Light exercises, such as walking, can usually begin soon after surgery, under the guidance of a physical therapist. More strenuous activities, like running or heavy lifting, should generally be avoided for at least 3 months, depending on the surgeon’s advice.

When will the final results be visible?


Final results, including improved mobility and reduced pain, are typically noticeable within 6 to 12 months, as the body fully adjusts to the new knee joint.

What types of activities should be avoided?


Patients should avoid high-impact activities such as running, jumping, or contact sports, as these can put too much strain on the new knee joint. Low-impact exercises like swimming, cycling, and walking are usually recommended.

What type of diet should the patient follow after surgery?


A balanced diet rich in protein, vitamins, and minerals is important for healing. Staying hydrated is also crucial. Additionally, a diet high in fiber can help prevent constipation, which is a common side effect of pain medications.

How Does Knee Replacement Procedure Work

Consultation


During the consultation, the surgeon will review your medical history, conduct a physical examination, and may order imaging tests like X-rays or MRIs. This helps the surgeon determine the extent of the knee damage and plan the surgery. You’ll also discuss the type of knee implant that will be used and any specific risks or concerns you might have.

Before the Surgery


In preparation for surgery, you’ll need to follow specific instructions from your surgeon. This may include stopping certain medications, fasting before the procedure, and arranging for transportation after the surgery. You might also undergo preoperative tests, such as blood work, to ensure you’re in good health for surgery.

The Surgery


The knee replacement surgery itself typically takes about 1 to 2 hours. During the procedure, the surgeon will remove the damaged parts of the knee joint and replace them with an artificial joint designed to mimic the function of a natural knee. This new joint should allow for smooth and pain-free movement.

Follow-Up


Follow-up appointments are usually scheduled a few days to a week after surgery. During these visits, the surgeon will check on your recovery progress, examine the surgical site, and discuss pain management. You may also be referred to a physical therapist to help you regain strength and mobility in your knee.

Side Effects of Knee Replacement Procedure

Some potential side effects or risks associated with arthroplasty include:

  • Infection at the surgical site
  • Blood clots
  • Stiffness in the knee joint
  • Nerve damage
  • Loosening or wear of the implant over time
  • Persistent pain or swelling
  • Differences in leg length

Knee Replacement Surgery Results

Knee replacement surgery is highly successful, with about 90% of patients experiencing significant pain relief and improved mobility. Most knee replacements last between 15 to 20 years, with some lasting even longer, depending on the patient’s activity level and overall health. According to a study, the success rate of knee replacement surgery is high, and the results can significantly enhance the quality of life for those suffering from severe knee pain.

How to Prepare for Knee Replacement Surgery

  • Avoid blood-thinning medications: These can increase the risk of bleeding during and after surgery, so your doctor will likely advise you to stop them several days before the procedure.
  • Refrain from smoking and alcohol consumption: It’s best to avoid these for at least two weeks before surgery, as they can impair healing.
  • Arrange transportation: Make sure you have someone to drive you home after surgery, as you won’t be able to drive yourself.
  • Plan for time off work: Depending on your job, plan to take at least 4 to 6 weeks off to allow for proper recovery.
