Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure performed to relieve pain and restore function in severely damaged knee joints. It is a common orthopedic procedure recommended for individuals with advanced arthritis or other degenerative conditions affecting the knee joint. In this comprehensive guide, we will explore the various aspects of knee replacement surgery, from pre-operative preparation to post-operative recovery.

What is Knee Replacement Surgery?

Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure aimed at relieving pain and restoring function in a severely damaged knee joint. During the procedure, the damaged cartilage and bone surfaces of the knee joint are replaced with prosthetic components made of metal, plastic, or ceramic materials. Knee replacement surgery can significantly improve mobility and quality of life for individuals suffering from advanced arthritis or other degenerative conditions affecting the knee joint.

What are the Different Types of Knee Replacement Surgery?

Total Knee Replacement (TKR)

In TKR, both the ends of the femur and tibia are replaced with prosthetic components, along with the kneecap or patella if necessary.

Partial Knee Replacement (PKR)

PKR involves the replacement of only one part of the knee joint, typically either the inside (medial) or outside (lateral) compartment of the knee.

Revision Knee Replacement

This procedure is performed to replace a previously implanted prosthetic knee joint that has become worn out, damaged, or infected.

Bilateral Knee Replacement

In bilateral knee replacement, both knees are replaced during the same surgical procedure, either simultaneously or in staged surgeries.

Who Might Need a Knee Replacement?

Knee replacement surgery may be recommended for individuals experiencing:

  • Chronic knee pain that limits daily activities and mobility.
  • Severe knee stiffness and swelling.
  • Persistent knee pain that does not respond to conservative treatments such as medication, physical therapy, and lifestyle modifications.
  • Advanced osteoarthritis, rheumatoid arthritis, or other degenerative problems affecting your knee joint.
  • Significant knee deformity or instability.

Preparing for Knee Replacement Surgery

Preparing for knee replacement surgery involves several essential steps to ensure a smooth and successful procedure and recovery process. Here are some points to consider:

1. Preoperative Evaluation

Your orthopaedic surgeons will conduct a thorough preoperative evaluation to assess your overall health, medical history, and the severity of your knee condition. This may include physical examinations, imaging tests (X-rays, MRI scans), and blood tests to ensure you are a suitable candidate for surgery.

2. Medical Clearance

Depending on your medical history and any underlying health conditions, your orthopaedic surgeons may request medical clearance from your primary care physician or other specialists to ensure that you are medically fit for surgery.

3. Medications

Your surgeon may advise you to adjust or temporarily discontinue certain medications, such as blood thinners or anti-inflammatory drugs, before surgery to minimize the risk of complications.

4. Physical Therapy

Preoperative physical therapy exercises may be prescribed to strengthen the muscles surrounding the knee joint, improve range of motion, and enhance overall joint function, which can facilitate a smoother recovery post-surgery.

5. Nutrition and Lifestyle

Maintaining a healthy diet, staying hydrated, and quitting smoking (if applicable) can help optimize your body’s healing ability and reduce the risk of complications during and after surgery.

6. Home Preparation

Make necessary arrangements at home to ensure a safe and comfortable environment for your recovery, such as installing handrails or grab bars in bathrooms, securing assistive devices like walkers or crutches, and arranging for assistance with daily tasks during the initial recovery period.

Before Knee Replacement Surgery

Consultation with the Best Knee Replacement Surgeon in Kanpur

Seek consultation with experienced orthopaedic surgeons specializing in knee replacement surgery. Choose the best orthopedic doctor in Kanpur with a proven track record of successful outcomes and patient satisfaction.

Evaluation and Pre-operative Preparation

  • Undergo a thorough evaluation, including medical history review, physical examination, and diagnostic tests such as X-rays and MRI scans, to assess the extent of knee damage and determine candidacy for surgery.
  • Follow pre-operative instructions provided by the orthopaedic surgeons, which may include medication adjustments, lifestyle modifications, and cessation of certain medications like blood thinners.

During Knee Replacement Surgery

Anesthesia and Incision

  • The surgery is performed under either general anesthesia, spinal anesthesia, or a combination of both, depending on the patient’s health status and surgical preferences.
  • The orthopaedic surgeons makes an incision over the knee joint, exposing the damaged surfaces of the knee bones.

Resurfacing and Implant Placement

  • The damaged cartilage and bone surfaces of the knee joint are removed and replaced with prosthetic components made of metal, plastic, or ceramic materials.
  • The orthopedic doctor meticulously positions the implants to restore proper alignment and function of the knee joint.

After Knee Replacement Surgery

Hospital Stay and Rehabilitation

  • After surgery, the patient is closely monitored in the hospital for pain management, wound healing, and early mobilization.
  • Physical therapy and rehabilitation exercises are initiated to improve strength, flexibility, and range of motion in the knee joint.

Post-operative Care and Follow-up

  • Follow the post-operative care instructions provided by the orthopaedic surgeons, including wound care, medication management, and activity restrictions.
  • Attend scheduled follow-up appointments with the orthopedic doctor for monitoring of progress and assessment of the surgical outcome.

Alternatives to Surgery

Before considering knee replacement surgery, individuals may explore non-surgical treatment options to manage knee pain and improve joint function. Some alternatives to surgery include:

1. Medications

Nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroid injections, and viscosupplementation injections may help alleviate knee pain and inflammation.

2. Physical Therapy

Exercise programs focusing on strengthening the muscles surrounding the knee joint, improving flexibility, and enhancing balance and stability can provide symptomatic relief.

3. Assistive Devices

Using supportive devices such as braces, orthotics, or walking aids may help reduce knee pain and improve mobility.

4. Lifestyle Modifications

Maintaining a healthy weight, engaging in low-impact activities, and adopting proper body mechanics can help alleviate knee pain and delay the need for surgery.


Knee replacement surgery is a highly effective treatment option for individuals suffering from debilitating knee pain and dysfunction due to arthritis or other knee conditions. By choosing the best knee replacement surgeon in Kanpur following pre-operative preparation, undergoing surgery, and adhering to post-operative rehabilitation protocols, patients can achieve significant improvements in knee function and quality of life.
