Knee Replacement Surgery: Procedure, Types, Risks, and the Expertise of Dr. Mrinal Sharma

Knee pain can significantly impact a person’s quality of life, making even simple tasks challenging. When non-surgical treatments no longer provide relief, knee replacement surgery becomes a viable option. In this comprehensive guide, we’ll delve into the procedure, types of knee replacement, and the associated risks, all with the added perspective of the expertise of Dr. Mrinal Sharma, a renowned Knee Replacement Surgeon.

Understanding Knee Replacement Surgery

Knee replacement surgery, also known as knee arthroplasty, is a medical procedure designed to alleviate pain and restore function in a severely damaged or arthritic knee. This surgical intervention involves removing damaged portions of the knee joint and replacing them with artificial components, often made of metal and plastic. The goal is to reduce pain, improve mobility, and enhance the overall quality of life.

The Procedure

The procedure can be broadly divided into the following steps:

  1. Preparation: Before the surgery, you’ll meet with your orthopedic surgeon, in this case, the renowned Dr. Mrinal Sharma. With his extensive experience and expertise, He will conduct a thorough examination, discuss your medical history, and provide you with the assurance and information you need.
  2. Anesthesia: In the capable hands of Dr. Mrinal Sharma, the anesthesiologist will administer anesthesia to ensure you’re comfortable and pain-free during the surgery. You may receive either general anesthesia, which puts you to sleep, or regional anesthesia, such as a spinal block, to numb the lower half of your body.
  3. Incision: The surgeon, in this case, the highly skilled Dr. Mrinal Sharma, makes an incision in your knee to access the joint. The type and size of the incision can vary depending on the specific procedure.
  4. Reshaping Bones: With the precision of an expert like Dr. Mrinal Sharma, the damaged bone and cartilage are removed. The end of the thigh bone (femur) and the top of the shinbone (tibia) are reshaped to accommodate the prosthetic components.
  5. Implantation: The artificial knee components, which typically consist of a metal alloy for the femur and tibia, and a plastic spacer in between, are implanted. Dr. Mrinal Sharma, with his knowledge of the latest advancements, will select the most appropriate prosthesis for your unique needs.
  6. Stabilization: The components are secured in place, and the knee is tested for stability and range of motion.
  7. Closure: The incision is expertly closed with sutures, staples, or adhesive, and a sterile dressing is applied.
  8. Recovery Room: You’ll be monitored in the recovery room to ensure your immediate post-operative needs are met, with Dr. Mrinal Sharma overseeing your initial recovery.

Recovery and Rehabilitation

Recovery from knee replacement surgery is a multi-stage process. After surgery, you’ll spend some time in the hospital to recover from the anesthesia and receive initial physical therapy. Rehabilitation plays a pivotal role in regaining function and strength. Over the weeks and months following the surgery, you’ll work closely with a physical therapist to regain mobility and strengthen the knee, all under the guidance of Dr. Mrinal Sharma. Full recovery can take several months, and it’s crucial to follow the prescribed rehabilitation plan diligently.

Types of Knee Replacement

Several types of knee replacement procedures are available to address different degrees of knee damage. Here are the primary ones:

  1. Total Knee Replacement (TKR): As mentioned earlier, TKR involves replacing the entire knee joint with artificial components. This is typically recommended when all three compartments of the knee are damaged.
  2. Partial Knee Replacement (PKR): In a PKR, only one compartment of the knee is replaced. It’s suitable when the damage is limited to one area, and it’s less invasive with a faster recovery compared to TKR.
  3. Kneecap Replacement (Patellofemoral Arthroplasty): This procedure is designed to address issues specifically in the kneecap and its groove in the thigh bone. It’s suitable for those with isolated patellofemoral arthritis.
  4. Bilateral Knee Replacement: For individuals with severe arthritis in both knees, bilateral knee replacement involves replacing both knees, either in a single surgery or in two separate procedures, with Dr. Mrinal Sharma’s expert guidance.

The choice of the procedure depends on the extent of knee damage, your age, overall health, and Dr. Mrinal Sharma’s recommendation based on his extensive experience.

Risks Associated with Knee Replacement Surgery

While knee replacement surgery is generally considered safe and effective, like any surgical procedure, it carries some inherent risks. It’s essential to be aware of these risks and discuss them with Dr. Mrinal Sharma before making a decision. Common risks and complications include:

  1. Infection: Infection at the surgical site is a risk with any surgery. Prophylactic antibiotics are typically administered to minimize this risk.
  2. Blood Clots: Deep vein thrombosis (DVT) and pulmonary embolism (PE) are potential complications. Measures like blood thinners, compression stockings, and early mobilization help reduce this risk, with Dr. Mrinal Sharma’s expertise in post-operative care.
  3. Implant Wear and Tear: Over time, the artificial knee components can wear out, necessitating a revision surgery. The longevity of the prosthesis varies by the type and the patient’s activity level, and Dr. Mrinal Sharma can advise on long-term care.
  4. Stiffness: Some individuals may experience postoperative stiffness. This can often be managed with physical therapy, guided by Dr. Mrinal Sharma’s expert team.
  5. Nerve and Blood Vessel Damage: While rare, injury to nerves or blood vessels can occur during surgery, potentially leading to persistent numbness, weakness, or bleeding.
  6. Pain: Pain after surgery is normal, but some patients may experience long-term discomfort. Medications, physical therapy, and other interventions can help manage pain, with Dr. Mrinal Sharma’s guidance.
  7. Allergic Reactions: Though uncommon, some individuals may have allergic reactions to the materials used in the prosthesis. Dr. Mrinal Sharma will ensure the selection of materials that suit your specific needs.
  8. Loosening of Implants: In some cases, the artificial components may loosen over time, leading to instability and pain. Regular follow-ups with Dr. Mrinal Sharma can help detect and address this issue early.
  9. Joint Instability: Patients may experience joint instability, which may require revision surgery to correct, with Dr. Mrinal Sharma’s expertise guiding the process.
  10. Limited Range of Motion: Achieving a full range of motion in the knee can be challenging for some patients, but Dr. Mrinal Sharma’s expert team can help you optimize your mobility.

It’s crucial to discuss these risks, along with your overall health, with Dr. Mrinal Sharma. His expertise and experience in knee replacement surgery will help you assess the potential benefits of surgery and the associated risks, allowing you to make an informed decision.


Knee replacement surgery has been a life-changing option for countless individuals suffering from chronic knee pain and limited mobility. While the procedure can significantly improve the quality of life, it’s essential to understand the process, types of knee replacement, and the associated risks. Working closely with an expert like Dr. Mrinal Sharma, a renowned Knee Replacement Surgeon, to make an informed decision based on your specific circumstances is the key to a successful knee replacement and a return to an active, pain-free life. Dr. Mrinal Sharma’s experience and expertise ensure that you receive the best care and guidance throughout your knee replacement journey.
