Our Summary

This research paper discusses the use of custom-made knee replacements. The study aimed to collate current research on this topic, as there’s not a lot of literature available. The researchers found that custom-made knee replacements are a reliable method that has shown good results in terms of rebuilding the leg’s structure, mimicking the natural movements of the knee, improving patient outcomes, and being cost-effective. These findings led the UK’s National Health Service’s Orthopaedic Data Evaluation Panel to give a high rating to the Conformis custom-designed knee replacement in 2017.

Doctor’s Tip

One helpful tip a doctor might tell a patient about knee replacement is to follow their rehabilitation plan closely. Physical therapy and exercises prescribed by the healthcare team are essential for regaining strength, flexibility, and range of motion in the knee after surgery. Consistent effort and dedication to the rehabilitation program can lead to a faster and more successful recovery.

Suitable For

Typically, patients who are recommended for knee replacement surgery are those who have severe knee pain and stiffness that limits their daily activities and affects their quality of life. These patients may have conditions such as osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, or other degenerative joint diseases. They may have tried other conservative treatments such as physical therapy, medications, and injections without success.

Other factors that may indicate a need for knee replacement surgery include:

  • Severe pain that is not relieved by medication
  • Difficulty walking or climbing stairs
  • Swelling and inflammation that does not improve with rest or medication
  • Significant joint deformity or instability
  • Failure of previous conservative treatments

It is important for patients to undergo a thorough evaluation by a healthcare provider to determine if they are a suitable candidate for knee replacement surgery. Custom-made knee replacements may be recommended for patients who have specific anatomical variations that may not be adequately addressed by traditional off-the-shelf implants. These custom-designed implants can provide a more precise fit and alignment, potentially leading to better outcomes and improved longevity of the joint replacement.

Timeline

Before knee replacement surgery:

  1. Patient experiences persistent knee pain, stiffness, and swelling that limits their ability to perform daily activities.
  2. Patient consults with an orthopedic surgeon who assesses their condition and determines if they are a candidate for knee replacement surgery.
  3. Patient undergoes pre-operative tests and evaluations to ensure they are in good health for surgery.

After knee replacement surgery:

  1. Patient undergoes the surgical procedure to replace the damaged knee joint with an artificial one.
  2. Patient stays in the hospital for a few days for post-operative care and rehabilitation.
  3. Patient begins physical therapy and rehabilitation exercises to regain strength and mobility in the knee.
  4. Patient may experience some pain, swelling, and stiffness in the knee post-surgery, which gradually improves with time.
  5. Patient gradually resumes normal activities and experiences improved quality of life with reduced knee pain and increased mobility.
