Minimally Invasive Surgery (MIS) for Knee Replacement

Knee replacement surgery has long been a beacon of hope for individuals suffering from severe knee arthritis or injury. However, the traditional approach often involves extensive recovery periods and significant post-operative discomfort. Enter Minimally Invasive Surgery (MIS) for knee replacement—a modern technique that is transforming patient experiences and outcomes. In this article, we'll explore the benefits, procedure, and frequently asked questions about MIS knee replacement, particularly highlighting its availability with top orthopaedic specialists in Mumbai, Dr. Amyn Rajani.

What is Minimally Invasive Surgery (MIS) for Knee Replacement?

Minimally Invasive Surgery (MIS) for knee replacement is a surgical technique designed to reduce the trauma associated with traditional knee replacement procedures. Unlike conventional methods, MIS involves smaller incisions and less disruption to the surrounding muscles and tissues. This approach leads to quicker recovery times, less post-operative pain, and improved mobility.

Key Benefits of MIS Knee Replacement:

  1. Reduced Pain: Smaller incisions and minimal tissue disruption significantly reduce post-operative pain.
  2. Faster Recovery: Patients can often return to their daily activities much sooner than with traditional surgery.
  3. Less Scarring: Smaller incisions mean less visible scarring.
  4. Improved Functionality: MIS aims to preserve as much of the natural knee structure as possible, leading to better functionality post-surgery.
  5. Decreased Hospital Stay: Many patients are able to leave the hospital sooner, reducing healthcare costs and the risk of hospital-acquired infections.


The Procedure of MIS Knee Replacement

  • Pre-Operative Preparation

Before undergoing MIS knee replacement, patients typically undergo a thorough evaluation by an orthopaedic doctor in Mumbai. This includes physical examinations, imaging tests like X-rays or MRIs, and a review of the patient's medical history. The goal is to ensure the patient is a suitable candidate for MIS.


  • Surgical Technique

The MIS technique for knee replacement involves the following steps:

  1. Incision: A small incision, usually 3 to 4 inches, is made over the knee joint. This is significantly smaller than the 8 to 10-inch incision used in traditional knee replacement.
  2. Tissue Sparing: The surgeon carefully navigates around muscles and tendons rather than cutting through them, which is common in traditional procedures.
  3. Implant Placement: Specialized instruments and advanced imaging techniques guide the precise placement of the knee implant.
  4. Closure: The incision is closed with sutures or staples, and a dressing is applied.


  • Post-Operative Care

Post-surgery, patients are encouraged to begin physical therapy almost immediately to promote healing and restore mobility. Regular follow-ups with the knee specialist in Mumbai are crucial to monitor progress and address any complications promptly.
