Complete details About the Types of Knee Replacement Surgery

Introduction

Knee replacement surgery is a common solution for managing advanced joint conditions like osteoarthritis. This degenerative disease often causes pain, swelling, and stiffness in joints, making daily tasks difficult. Osteoarthritis affects various joints, including the hips, hands, knees, and spine, and is typically more common in older adults, those with excess body weight, and individuals with a history of joint injury or overuse. Women are generally more affected than men. Early intervention through exercise and diet can help manage symptoms, but severe cases may require surgical intervention, especially knee replacement surgery.

What is Knee Replacement Surgery?

Knee replacement surgery, also known as knee arthroplasty, is performed to replace damaged parts of the knee joint, either partially or entirely. The goal is to alleviate pain and enhance knee mobility. During a pre-surgical evaluation, your surgeon will assess your knee’s strength, stability, and range of motion, often using X-rays to determine the extent of the joint damage. Factors like knee size, age, weight, activity level, and overall health are used to select the best implant and surgical approach for each patient.

Why is Knee Replacement Surgery Needed?

Knee replacement surgery is commonly recommended to relieve arthritis pain and improve knee function. Symptoms often include difficulty walking, standing from a seated position, and climbing stairs. Depending on the extent of knee damage, the surgeon may opt for a partial or total knee replacement:

Total Knee Replacement: This involves replacing all three knee joint components—the medial (inside), lateral (outside), and patellofemoral (kneecap) sections. It’s the most frequently performed knee replacement surgery.

Partial Knee Replacement: Here, only one or two sections of the knee joint are replaced. Partial replacements are more common in younger patients following an injury or trauma and generally involve faster recovery.

Types of Knee Replacement Implants

Different types of implants are available for knee replacement surgery. The choice of implant depends on factors like longevity, material type, and the patient's allergies or sensitivities.

Metal-on-Plastic Implant: The most common and cost-effective type, consisting of a non-reactive metal alloy and a biocompatible plastic component. Durable and widely used, although in rare cases it may cause immune reactions.

Ceramic-on-Ceramic Implant: This implant uses ceramic components for both the femur and tibia. It’s a safe option with minimal immune response but tends to be noisier.

Metal-on-Metal Implant: Consisting of metal components for both femur and tibia, this type is highly durable, although it has decreased in popularity due to potential side effects.

Ceramic-on-Plastic Implant: Ideal for patients with nickel allergies, this implant has a ceramic femoral component and a plastic spacer.

Success Rate of Knee Replacement Surgery

According to the American Academy of Orthopaedic Surgeons (AAOS), knee replacement surgery has a high success rate, with 90% of patients experiencing significant pain relief. More than 90% of knee replacements are still functioning well 15 years after surgery, and around 82% remain effective even after 25 years. A successful knee replacement offers improved mobility, reduced pain, and a better quality of life.

Factors Influencing the Cost of Knee Replacement Surgery in India

Doctor’s Expertise: Higher expertise often means a higher cost due to the surgeon’s skills and successful case history.

Doctor’s Experience: More experienced surgeons tend to charge more for their services.

Extent of Knee Damage: Severe knee damage requires complex surgery, increasing costs.

Patient’s Health Status: Older patients or those with pre-existing conditions may require more postoperative care, raising the expense.

Insurance Coverage: If the procedure isn’t covered, patients may incur higher out-of-pocket expenses.

Pre-Surgical Tests: Diagnostic tests can add to the total cost.

Hospital Fees: Private hospitals generally charge more than government or smaller regional hospitals.

Type of Surgery: Depending on the extent of the damage, a total or partial replacement may be chosen, affecting cost.

City of Treatment: Hospitals in major cities like Delhi, Mumbai, and Chennai tend to charge more than those in smaller cities.
