All Details About Knee Replacement Surgery

You cannot move like you formerly did. It is excruciating to walk the dog, ascend a flight of stairs, or even rise from a chair. You have already attempted medications, injections, and physical therapy. Nothing is working. If this is the case, knee replacement surgery may be necessary.



Knee replacement surgery, also known as arthroplasty, is one of the most common bone procedures. It can reduce the discomfort associated with severe arthritis.

It may also improve your mobility. Most knee replacement procedures are currently performed robotically.

An orthopedic surgeon removes the injured portion of the knee during surgery and replaces it with a metal-and-plastic prosthetic joint. The prosthetic joint is then secured to the thigh bone, shinbone, and kneecap using a specific adhesive such as acrylic cement. Dr. A K Sharma is the best knee replacement surgeon in Noida for all knee replacement surgeries.


Why do I require surgery?

Osteoarthritis is the primary reason individuals need knee replacement surgery. The age-related problem arises when cartilage — the cushion between the knee and the bone joints — deteriorates.


Additional reasons include:

Rheumatoid arthritis occurs when the immune system of the body assaults and damages the lining of the knee.

Deformities: People with bent legs or "knock-knees" frequently have surgery to restore the knee's posture.

Knee injuries: A damaged bone or torn ligaments surrounding the knee can lead to arthritis, which causes severe discomfort and limits mobility.


Different Types of Surgery

There is five primary knee replacement surgery:

Total knee replacement: This is the most widespread type. Your surgeon will replace the thigh and shin bone surfaces attached to the knee.

Partial knee replacement: If only one side of your knee is affected by arthritis, this surgery may be an option. However, you only qualify if your knee ligaments are sturdy and the remainder of your knee cartilage is healthy. A smaller incision is needed for a partial knee replacement.

Patellofemoral replacement: This replaces the underside of the kneecap and the groove in which it rests. People with persistent kneecap arthritis may find this quite helpful.

Complex knee replacement (or revision): This treatment may be necessary if you have severe arthritis or have previously undergone two or three knee replacement procedures.

Cartilage restoration: When the knee has only an isolated region of damage or wear, this area can be replaced with a live cartilage transplant or cells that differentiate into cartilage.


Different Designs

Knee replacement surgery, which may last between one and two hours, has become so accurate that surgeons can pick from a range of knee designs based on the patient's height, weight, and degree of activity.

Implants comprise various materials, including metal, ceramic, and plastic. They are constructed for mobility. Certain implants are designed specifically for the female anatomy.

The PCL (posterior cruciate ligament) in the rear of the knee is replaced with a standard prosthetic knee design. Another substitute is the ACL (anterior cruciate ligament). Some prosthetic knees are designed for partial joint replacement, while others leave the PCL and ACL intact.


How Much Time Do They Last?

In the early 1970s, doctors began replacing knees for the first time. Doctors then estimated that the replacement knees would last around a decade. Current implants have a 20-year lifespan.

Five Symptoms of a Thumb Sprain

A Sprained Thumb: What Is It? Unlike a thumb fracture (break), which affects the bone, a sprained thumb affects the ligament, which is a soft tissue that stabilizes the joints by connecting bones. The thumb ligament that sustains injuries the most is the ulnar collateral ligament. The thumb and the hand on the side that is next to your index finger are joined by this specific ligament. Thumb sprains are frequently caused by falls or sports-related injuries. For instance, thumb injuries are common in contact sports like basketball and volleyball. In volleyball, setting the ball torques the thumb as well.  A common injury to the thumb is an ulnar collateral ligament (UCL) tear; also called “skier’s thumb” or “gamekeeper’s thumb”. Symptoms of a Sprained Thumb So, is it just a jammed finger, a broken thumb, or a sprained thumb? The following five indications point to a sprained thumb: 1. Bruising 2. Swelling 3. Pain 4.

While these injuries can be painful and debilitating, incorporating regular stretching routines into your daily life can significantly reduce your risk of injury and improve your overall physical performance. The Importance of Shoulder Stretches The shoulder joint is one of the most complex joints in the human body, and it is prone to injury due to overuse, trauma, or underlying conditions. Regular shoulder stretches can help to: Increase flexibility: Improved flexibility allows for greater range of motion, reducing the risk of strains and tears. Enhance strength: Stronger shoulder muscles can better support the joint, reducing the risk of instability and dislocation. Reduce pain: Stretching can help to alleviate pain and discomfort associated with conditions like shoulder impingement syndrome and rotator cuff ...
