Doctor’s Tip

One helpful tip a doctor might tell a patient about knee replacement surgery is to follow the prescribed rehabilitation and physical therapy program diligently. This is crucial for achieving optimal results and regaining strength and mobility in the affected knee. It’s important to commit to the exercises and activities recommended by your healthcare team to ensure a successful recovery and long-term success of the knee replacement.

Suitable For

Patients who are typically recommended for knee replacement surgery are those who have severe knee pain and stiffness that limits their everyday activities, such as walking, climbing stairs, and getting in and out of chairs. These patients may also have tried other treatments such as medications, physical therapy, and cortisone injections without success. Additionally, patients with advanced arthritis, deformities in the knee joint, or previous knee injuries may also be good candidates for knee replacement surgery.

It is important for patients considering knee replacement surgery to consult with their healthcare provider to determine if they are a good candidate for the procedure. The decision to undergo knee replacement surgery should be based on a thorough evaluation of the patient’s overall health, lifestyle, and expectations for the surgery. Additionally, patients should be aware of the potential risks and benefits of knee replacement surgery, as well as the expected recovery process and rehabilitation.

Timeline

Before knee replacement surgery:

  1. Patient experiences chronic knee pain, stiffness, and limited mobility.
  2. Patient consults with an orthopedic surgeon to discuss the possibility of knee replacement surgery.
  3. Pre-operative tests and evaluations are conducted to determine if the patient is a suitable candidate for surgery.
  4. The surgeon discusses the procedure, potential risks, and expected outcomes with the patient.
  5. The patient undergoes pre-operative physical therapy to strengthen the muscles surrounding the knee.

After knee replacement surgery:

  1. The patient undergoes the surgery, which involves removing damaged cartilage and bone and replacing them with artificial components.
  2. The patient is monitored closely in the hospital for a few days post-surgery to manage pain and monitor for any complications.
  3. The patient begins physical therapy to regain strength, flexibility, and range of motion in the knee.
  4. The patient gradually increases activity levels under the guidance of a physical therapist.
  5. Follow-up appointments with the surgeon are scheduled to monitor progress and address any concerns.
  6. Over time, the patient experiences improved mobility, reduced pain, and a better quality of life due to the successful knee replacement surgery.
