Knee Replacement Surgery: Everything You Need to Know

Knee pain is one of the most common complaints among adults, especially those above the age of 50. Whether caused by arthritis, injury, or general wear and tear, chronic knee pain can significantly impact your mobility and quality of life. In cases where medications, physical therapy, and other conservative treatments fail to bring relief, knee replacement surgery may be the best option.

In this comprehensive guide, we will explore everything you need to know about knee replacement, including the types, benefits, risks, recovery, and how to choose the best orthopedic surgeon for your needs.

What is Knee Replacement Surgery?

Knee replacement surgery, also known as arthroplasty, is a medical procedure in which a damaged or worn-out knee joint is replaced with an artificial joint (prosthesis). This procedure helps relieve pain, improve joint function, and restore mobility.

There are two main types of knee replacement:

• Total Knee Replacement (TKR): The entire joint is replaced with artificial components.

• Partial Knee Replacement (PKR): Only the damaged portion of the knee is replaced, preserving healthy bone and tissue.

Who Needs Knee Replacement?

Knee replacement is generally recommended for individuals who suffer from:

• Severe osteoarthritis or rheumatoid arthritis

• Post-traumatic arthritis due to a previous injury

• Chronic knee pain that limits daily activities

• Deformity in the knee joint

• Lack of response to non-surgical treatments like medication, injections, or physical therapy

The decision to undergo knee replacement should always be made in consultation with a qualified orthopedic surgeon who can evaluate your condition and overall health.

Common Causes of Knee Damage

Understanding the underlying causes of knee damage helps determine the need for surgery. Some of the common causes include:

1. Osteoarthritis

A degenerative joint disease that affects millions, osteoarthritis causes the cartilage in the knee to wear away, leading to pain, swelling, and stiffness.

2. Rheumatoid Arthritis

An autoimmune disorder, rheumatoid arthritis leads to inflammation in the joint lining, causing damage and eventual joint deformity.

3. Post-Traumatic Arthritis

Injuries such as fractures, ligament tears, or meniscus damage can lead to post-traumatic arthritis, especially if not treated correctly.

Benefits of Knee Replacement Surgery

The advantages of undergoing knee replacement surgery are numerous and life-changing for many patients:

• Pain relief from chronic knee pain

• Improved mobility and joint function

• Better quality of life

• Correction of deformities in the knee

• Ability to return to normal activities such as walking, climbing stairs, or even light sports

Preparing for Knee Replacement Surgery

Preparation is key to a successful surgery and smooth recovery. Here are some essential steps:

1. Medical Evaluation

Your orthopedic surgeon will conduct a thorough examination, including X-rays, MRI scans, and blood tests to ensure you're a suitable candidate.

2. Pre-Surgical Instructions

You may be asked to:

• Stop smoking (if applicable)

• Manage diabetes or hypertension

• Avoid certain medications

• Do pre-surgery exercises to strengthen the muscles

3. Home Preparation

Arrange your home for easy movement after surgery:

• Install handrails in the bathroom

• Clear pathways of obstacles

• Place essentials within easy reach

• Arrange for someone to assist you in the first few weeks

The Knee Replacement Procedure

Knee replacement surgery is typically performed under spinal or general anesthesia and lasts between 1 to 2 hours. Here’s a general overview of the procedure:

1. Incision: A surgical cut is made over the knee.

2. Removal: Damaged bone and cartilage are removed from the thighbone, shinbone, and kneecap.

3. Implant Placement: The artificial joint is placed and secured using bone cement or other materials.

4. Closure: The incision is closed, and a drain may be inserted to remove excess fluids.

Recovery After Knee Replacement

Recovery is a gradual process that typically takes 6 to 12 weeks, though full healing can take up to a year.

1. Hospital Stay

Patients usually stay in the hospital for 2 to 3 days. You will start walking with the help of a physiotherapist within a day after surgery.

2. Pain Management

Pain and swelling are normal. Your doctor will prescribe medications to manage discomfort and prevent infections.

3. Physical Therapy

Rehabilitation exercises are crucial to regain strength and mobility. Regular physiotherapy sessions will include:

• Knee bending and straightening

• Walking with support

• Muscle strengthening exercises

4. At-Home Care

• Follow the prescribed exercise routine

• Keep the surgical area clean and dry

• Avoid high-impact activities

Risks and Complications

While knee replacement surgery is generally safe, like any surgical procedure, it carries some risks:

• Infection

• Blood clots

• Implant loosening or wear

• Stiffness or limited range of motion

• Nerve or blood vessel damage

Choosing a highly experienced orthopedic surgeon can minimize the risk of complications.

Choosing the Best Orthopedic Surgeon for Knee Replacement

When considering knee replacement surgery, selecting the right orthopedic specialist is crucial. Here’s what to look for:

• Qualifications and experience: Choose a board-certified surgeon with extensive experience in joint replacements.

• Patient reviews: Positive feedback from past patients can help you gauge the doctor’s reputation.

• Advanced technology: Surgeons using robotic-assisted techniques often deliver better precision and outcomes.

• Hospital affiliation: Check if the surgeon is affiliated with a reputed hospital equipped with modern facilities.

• Post-operative care: Choose a surgeon who offers comprehensive rehabilitation and follow-up care.

Searching for the best orthopedic surgeon in [City] or knee replacement doctor near me can lead you to reliable options. Always schedule a consultation to understand the process, expected results, and ask questions.

Cost of Knee Replacement in India

The cost of knee replacement surgery varies depending on factors like:

• Type of surgery (total or partial)

• Surgeon’s experience

• Type of implant

• Hospital facilities

• Location

On average, the knee replacement cost in India ranges from ₹1.5 lakh to ₹3.5 lakh per knee, making it a more affordable option compared to other countries. Insurance coverage and cashless facilities may also reduce the burden.

Life After Knee Replacement: What to Expect

Most patients experience a dramatic improvement in pain and mobility after surgery. However, it's important to maintain healthy habits to ensure long-term success:

• Maintain a healthy weight

• Continue low-impact exercises like walking, swimming, or cycling

• Avoid high-impact activities that can damage the implant

• Follow-up with your doctor regularly

Artificial knees generally last 15 to 20 years or more, depending on usage and care.
