All You Need to Know About Primary Knee Replacement – A Guide by Dr. (Prof.) Anil Arora Joint Replacement

 If you've been struggling with knee pain, stiffness, or limited movement that affects your daily life, you’re not alone. Many people face these issues, especially with age, injury, or arthritis. The good


news? Modern medicine has come a long way, and Primary Knee Replacement (also known as Total Knee Arthroplasty) has become one of the most successful procedures to relieve pain and restore mobility.

Understanding Your Knee Joint

Your knee acts like a hinge – where your thigh bone (femur) meets your shin bone (tibia). In a healthy knee, a smooth layer of cartilage covers the ends of these bones, allowing them to glide over each other easily. This lets you walk, sit, stand, and move around without discomfort.

But over time, that smooth cartilage can wear away. The result? Bones start grinding against each other like sandpaper, causing pain, stiffness, swelling, and reduced movement.

Why Do Knees Get Damaged?

There are several reasons why your knee joint may start to break down:

  • Osteoarthritis – the most common cause

  • Injuries or fractures

  • Excess body weight or overuse

  • Rheumatoid arthritis or inflammation

  • Connective tissue disorders

  • Side effects of long-term steroid use

  • Lack of physical activity

If your x-rays show damage and your symptoms interfere with daily activities, your doctor might suggest knee replacement surgery.

What is Primary Knee Replacement?

Primary Knee Replacement is a surgery where the damaged parts of the knee joint are removed and replaced with artificial components (called prostheses) made of metal and strong plastic. These parts mimic your natural joint and allow smooth, pain-free movement.

Depending on your condition, these parts can be fixed with bone cement or designed to let your natural bone grow into them for stability.

When Is It Time for Surgery?

Surgery is usually recommended when:

  • Pain keeps you from doing everyday activities

  • Other treatments like medication, injections, or physiotherapy haven’t helped

  • X-rays show severe joint damage

This procedure is especially common in older adults, but younger people with joint damage may also benefit.

What Happens After Surgery?

Dr. (Prof.) Anil Arora Joint Replacement team focuses on early recovery and mobility. In many cases, patients stand up and even begin walking on the same day or the next day after surgery. Physical therapy usually starts right away to help you regain strength and motion.

Your surgeon will guide you on how much weight you can put on your leg (this is called your Weight Bearing Status), and this may change as you heal.

You’ll likely use a walker, crutches, or a cane at first. Mild pain after surgery is normal as your body heals, but it usually fades within weeks. Your medical team will help manage any discomfort with pain relief and regular checkups.

Life After Knee Replacement

With dedication to your recovery exercises and physiotherapy plan, most patients regain excellent mobility. You might soon return to doing things you love, such as:


  • Walking comfortably

  • Gardening

  • Dancing

  • Cycling

  • Playing golf

A successful Total Knee Replacement improves quality of life, boosts independence, and helps you enjoy a more active lifestyle.

If you're struggling with constant hip pain, stiffness, or difficulty walking, you're not alone. Hip problems affect millions of people, especially with age or certain health conditions like arthritis. When conservative treatments like medications and physical therapy stop helping, doctors may suggest a Primary Hip Replacement .

Primary Hip Replacement (also called Total Hip Arthroplasty) is a surgical procedure in which the damaged or worn parts of the hip joint are removed and replaced with an artificial joint, called a prosthesis. The hip is a ball-and-socket joint where the ball (femur head) fits into the socket (pelvis). In this surgery, both the ball and the socket are replaced with metal and plastic components that mimic the movement of a natural joint. The word "primary" means this is the first-time r...

Computer-Assisted Knee Replacement: A Revolution in Precision Surgery

 Knee replacement surgery has come a long way with advancements in medical technology. One of the most significant innovations in recent years is Computer-Assisted Knee Replacement , a cutting-edge approach that enhances precision and improves patient outcomes. Why is Alignment Important in Knee Replacement? The success of a knee replacement depends on the proper alignment of the implant and the balance of surrounding soft tissues. Even minor misalignment can lead to early wear and tear, loosening of the implant, and discomfort for the patient. Traditionally, surgeons have relied on manual methods using jigs and rods to position knee implants. While these techniques have been effective, they sometimes result in small errors that may impact the longevity of the knee replacement. How Does Computer-Assisted Knee Replacement Work? With computer-assisted technology, Dr. (Prof.) Anil Arora Joint Replacement and his team use advanced navigation systems to achieve a high degree of precis...
