Knee Replacement Surgery

Treatment Overview

Knee replacement surgery is one of the most frequently performed orthopedic or musculoskeletal surgical procedures in highly affordable cost brackets. Globally, the number of cases performed is rising exponentially, although procedural rates vary greatly across countries and regions. Primarily, the surgery addresses the debilitating effects of knee osteoarthritis, characterized by excruciating pain and diminished functionality, impacting the quality of life. The decision to undergo surgery lacks precise criteria and is influenced by various factors including patient and surgeon preferences.

Most patients who receive a knee replacement have outstanding clinical outcomes. However, many research investigations indicate that few of patients do not respond well to the treatment. As a result, even with the procedure's exceptional long-term survivorship, its success also depends on the surgeon's expertise, availability of required infrastructure, and proficiency with technically advanced surgical equipment.

Although it has long been thought that altering the design of implants would improve results, there is growing awareness that better implantation techniques, preventing complications, and enhancing patient perioperative care, such as more intensive recovery programs, can also lead to outstanding improvements in overall procedural outcomes.

The integration of new technologies holds promise for advancing knee replacement care in the future. However, their implementation requires careful regulation and vigilant monitoring to safeguard patient well-being. If you or your loved ones are suffering from knee joint degeneration, then you are at the right place. Dr. Ishwar Bohra is one of the top orthopedic surgeons in India. He has earned great merits and has been recognised as one of the best doctors for knee replacement surgery in India. People are experiencing best outcomes from the surgeries performed by Dr. Bohra.

Knee Replacement Surgery

What is Knee Replacement Surgery?

Through knee replacement surgery, damaged or worn-out knee or parts of it are replaced partially or completely with implants/prosthetics via surgical intervention. The procedure can improve knee function and reduce pain. Damaged bone and cartilage are replaced during the procedure with metal and plastic components.

Your surgeon will examine your knee's strength, stability, and range of motion to determine if a replacement is the best course of action for you. X-rays support the damage assessment. The appropriateness of joint prosthetics and surgical methods for you will depend on your age, weight, degree of physical activity, knee dimensions, and general health status.

Types of Knee Replacement Surgery

Your orthopedic surgeon will advise you full or partial replacement depending upon the extent and severity of damage:

Total knee replacement

The most common kind of knee replacement procedure is a total knee replacement. All three components of your knee joint (medial, lateral, and patellofemoral) will all be replaced by your surgeon.

Partial knee replacement

This is precisely what it sounds like. A partial knee replacement is performed if your knee joint is not completely damaged. Your surgeon will likely replace only those components of the knee that are degenerated. After suffering an injury or trauma, younger adults are more likely to undergo partial knee replacements.

Purpose of Knee Replacement Surgery

Reducing arthritis pain is the most common reason for knee replacement surgery. Knee joint replacement may be advised by your healthcare professional if:

  • Knee arthritis is causing you pain that prevents you from sleeping or going about your daily business.
  • Getting out of chairs, walking, and climbing stairs is getting difficult
  • Other treatments have not made your knee pain go better

This surgery is typically performed on patients 60 years of age and older. Younger patients who have had knee replacements may overuse their prosthetic knee, shortening its lifespan and causing it to wear out more quickly.

Knee Replacement Surgery Preparation

Following are the preparatory steps for the surgery:

    • Thorough physical examination to confirm the need for surgery
    • Imaging tests including knee X-ray, magnetic resonance imaging (MRI), and/or computed tomography (CT) scan to further evaluate the knee condition and to decide the type of surgery to be undertaken
    • Other tests including complete blood analysis, urinalysis, an ECG (to evaluate the health of your heart), oral examination
    • Tell your doctor about all of the over-the-counter medications and supplements you currently take or have taken in the past.
    • Prior to your procedure, you will be asked to cease taking specific drugs or supplements. Since some medications may impede the healing process following surgery like NSAIDS
    • Your orthopedic surgeon will give you instructions on when to stop eating and drinking the day before surgery. For most patients, the 12-hour period before surgery involves no food or liquids.

Knee Replacement Surgery Procedure

Surgeons often replace just the damaged portion of the knee if only one portion is affected. The thigh and shin bone ends are reshaped, and the joint is completely resurfaced, if the knee joint is severely damaged and complete replacement of the joint is necessary. These bones are composed of hard tubes with soft centers. The soft middle region of the bones receives the ends of the artificial components.

Tissue bands called ligaments aid in keeping joints together. The surgeon might select implants with connectable components if the knee's ligaments are insufficiently strong to hold the joint together on their own. Following are the steps involved in the surgery:

  • You will receive either a general anesthetic, which creates a sedative-like state, or a spinal block, which numbs the lower body
  • Your surgeon may also inject numbing medication in the vicinity of nerves or in and around the joint to lessen pain after surgery
  • The surgeon will make an incision over the knee
  • Damaged cartilage and bone is removed
  • Prosthetic knee joint is placed carefully
  • A plastic spacer is inserted to recreate the smooth cushion of the cartilage that was removed
  • Patella (kneecap) is reshaped to fit the prosthetic knee joint
  • Sutures will be place to close the incisions and area will be sterilized

Post-Procedure Care for Knee Replacement Surgery

  • You will spend a few hours in a recovery area following surgery till your anesthesia effects gets over
  • Your blood pressure, pulse, level of alertness, pain or comfort, and medication requirements will all be observed by medical care team
  • To help prevent fluid from entering your lungs, you will be asked to blow into a device, cough, or take deep breaths.
  • The duration of your stay following surgery is determined by your individual requirements.
  • Your anesthesiologist will ensure that your anesthesia wears off properly and that there are no postoperative complications before you get discharged.v

Recovery After Knee Replacement Surgery

    • The recovery period following knee surgery usually lasts between six and twelve months, but it can sometimes take longer.
    • Most people can resume driving in 4-6 weeks, depending on their unique circumstances; people who have had surgery on their left knee may be able to resume driving sooner. Make sure you can bend your knee enough to operate the pedal.
    • When taking medication that could affect your ability to drive, avoid driving and always check with your doctor if plan driving
    • Returning to work usually takes three to six weeks, though this time frame may change depending on the type of work you do. If you work from home, you might be able to return in ten days, but if you have a labor-intensive job, it might take three months or longer.
    • To avoid blood clots during the flight, think about donning compression stockings, stretching frequently, and performing foot exercises.
    • Walk as soon as you can, at first with the aid of assistive aids.
    • After around 12 weeks, progressively raise your activity levels, including low-impact activities like swimming.
    • After knee replacement, there is a higher risk of infection for the first two years. Before invasive procedures like dental work, antibiotics might be required.
