Exploring Minimally Invasive Techniques in Knee Replacement Surgery

12 mins read


Every year, millions of people globally are confronted with knee problems that severely hamper their quality of life. A growing trend among these individuals is undergoing knee replacement surgery to regain mobility and alleviate pain. Total knee replacement, also known as total knee arthroplasty, has revolutionized orthopedic surgery, offering hope to those who have suffered from debilitating knee conditions. In recent years, India has seen an upward trajectory in knee surgeries, making it a hub for affordable and quality knee replacement surgeries. The purpose of this blog is to delve into the details of knee replacement surgery, the various minimally invasive techniques available, the cost implications, and the expected recovery time.

Minimally Invasive Techniques in Knee Replacement Surgery

Minimally invasive techniques in knee replacement surgery have revolutionized the way this procedure is performed, providing several advantages over traditional open surgery. These techniques aim to reduce surgical trauma, minimize scarring, decrease recovery time, and improve patient outcomes. Let’s explore some of the key aspects of minimally invasive knee replacement surgery:

Smaller Incisions: One of the primary features of minimally invasive knee replacement is the use of smaller incisions compared to traditional surgery. Instead of a single large incision, surgeons make one or more smaller incisions, typically around 3 to 6 inches in length.

Tissue-Sparing Approach: Minimally invasive techniques focus on sparing surrounding muscles and tissues. Specialized instruments and surgical approaches allow surgeons to work around muscles instead of cutting through them, leading to less muscle damage.

Reduced Blood Loss: Smaller incisions and tissue-sparing approaches result in reduced blood loss during the procedure. This can lead to a lower risk of needing a blood transfusion during surgery.

Faster Recovery: Minimally invasive knee replacement often leads to a quicker recovery compared to traditional open surgery. The reduced trauma to tissues allows patients to experience less pain and swelling, and they can often start moving and walking sooner.

Shorter Hospital Stay: Due to the faster recovery and reduced postoperative complications, patients who undergo minimally invasive knee replacement surgery typically have shorter hospital stays, with some patients even being discharged on the same day as surgery.

Improved Cosmesis: Smaller incisions result in smaller scars, which can be less noticeable and more cosmetically appealing compared to the larger scars associated with traditional knee replacement surgery.

Precision and Technology: Minimally invasive knee replacement surgery often incorporates advanced technologies like computer-assisted navigation and robotic assistance. These technologies help surgeons achieve greater precision in implant positioning, potentially leading to better long-term outcomes.

Potential Drawbacks: Minimally invasive knee replacement surgery may not be suitable for all patients or all types of knee conditions. In some cases, the surgeon may need to convert to a traditional open technique if they encounter unexpected difficulties during the procedure.

It’s essential to note that while minimally invasive knee replacement offers numerous benefits, the decision to use this approach depends on the individual patient’s condition, the surgeon’s experience, and the availability of the necessary equipment and resources.

As with any surgical procedure, risks and potential complications are possible. Patients considering knee replacement surgery should have a thorough discussion with their orthopedic surgeon to determine the most appropriate approach based on their unique circumstances.

The Journey of Knee Replacement Surgery in India

The quality of knee replacement surgery in India has steadily improved over the years, with the country boasting some of the best knee replacement surgeons globally. India has become a preferred destination for many looking to undergo this procedure due to the affordable knee replacement surgery cost in India compared to other countries.

Before and After Knee Replacement Surgery

Here’s what happens before and after a knee replacement surgery:

Before Knee Replacement Surgery

  • Evaluation: Your orthopedic surgeon will review your medical history, conduct a physical examination, and likely recommend imaging tests (like X-rays, MRI, etc.) to assess the extent of damage to your knee joint.
  • Preparation: You may need to undergo a series of pre-operative tests such as blood tests, EKG, or a complete physical examination to ensure you’re in good health for surgery. You may also need to stop taking certain medications and supplements.
  • Physical therapy: Some doctors recommend pre-surgical physical therapy to strengthen the muscles around your knee, which can help speed your recovery after surgery.
  • Home preparation: Since mobility will be limited after surgery, it is advised to make some adjustments at home. This may include setting up a sleeping area on the first floor, installing safety bars in the bathroom, or arranging for assistance during the initial recovery period.

After Knee Replacement Surgery

  • Recovery in the hospital: Typically, you’ll start moving the replaced knee as soon as possible, often within a day of the surgery. Most patients are able to walk with the aid of walking support and under the supervision of a physiotherapist within a day or two following surgery.
  • Pain management: Post-surgery, you will be on medication to handle the pain. It is crucial to manage the pain well because it allows you to start moving the replaced joint sooner.
  • Physical therapy: A physical therapist will provide you with exercises to help strengthen your knee and improve flexibility. This is a vital part of the recovery process and is usually continued for weeks to months after surgery.
  • Follow-up visits: Your surgeon will schedule regular follow-up visits to monitor your progress, adjust your rehabilitation program as necessary, and check for any complications.
  • Long-term care: A successful knee replacement can last up to 20 years or more, depending on your age, activity level, and other factors. However, you may need to avoid certain high-impact activities to prevent wear and damage to the artificial joint.

The Cost of Knee Replacement Surgery in India

 Here’s an approximate cost breakdown for knee replacement surgery in India:

Total Knee Replacement (Unilateral – One Knee):

  • Standard Implant: ₹2,50,000 to ₹4,50,000 
  • High-End Implant: ₹4,50,000 to ₹6,50,000 

Total Knee Replacement (Bilateral – Both Knees):

  • Standard Implants: ₹4,50,000 to ₹7,50,000 
  • High-End Implants: ₹7,50,000 to ₹10,00,000 

Please note that these are rough estimates and the actual cost may vary. It’s important to consider that the prices for high-end implants may be significantly higher, but they often come with advanced features and materials that may improve the longevity and performance of the implant.

Additionally, the cost mentioned above is typically inclusive of hospital charges, surgeon’s fees, anesthesia, pre-operative investigations, post-operative care, and a standard hospital stay. However, some hospitals may provide different packages or have additional charges for specific services or requirements.
