Knee pain caused by osteoarthritis, rheumatoid arthritis, or severe injury can significantly impact mobility and quality of life. When medications, physiotherapy, and lifestyle modifications no longer provide relief, knee replacement becomes a highly effective treatment option. This blog explains the knee replacement procedure, different types of implants, and how modern technologies—like those used at XLO – Ortho Life Systems Pvt. Ltd.—enhance surgical outcomes.

What Is Knee Replacement?

Knee replacement, also known as knee replacement surgery or full knee replacement, is a surgical procedure in which damaged cartilage and bone are removed and replaced with artificial components called knee implants.

This procedure is performed to relieve pain, correct deformity, and restore function to the knee joint.

Types of Knee Replacement Surgery

Total Knee Replacement (TKR) –

1. In a total knee replacement, all three compartments of the knee—medial, lateral, and patellofemoral—are replaced with total knee replacement implants.
2. This is the most common and the most successful knee replacement surgery procedure.

Partial Knee Replacement

• Only the damaged portion of the knee is replaced. This option is recommended when arthritis affects a single compartment.

Knee Replacement Procedure – Step by Step

A standard knee replacement procedure includes the following steps:

1. 1. Pre-Operative Assessment
      • Physical examination
      • X-rays and MRI
      • Evaluation of medical conditions
      • Selecting the best knee replacement implant based on patient anatomy
   2. Anesthesia
      • General or spinal anesthesia is given for a painless surgical experience.
   3. Surgical Steps
      • Making an incision at the front of the knee
      • Removing damaged cartilage and bone
      • Preparing the joint surfaces
      • Placing the total knee replacement implants
      • Testing range of motion
      • Closing the incision

Total Knee Replacement Implants – Materials & Design

The success of a total knee replacement surgery depends largely on the implant quality.

1. 1. Common Materials Used
      • Cobalt-chromium alloys
      • Titanium alloys
      • Polyethylene insert
      • Oxidized zirconium (advanced wear-resistant material)
   2. Implant Designs Offered by XLO
      At xlo.in, we manufacture premium orthopaedic solutions including:
      • Fixed-bearing knee implants
      • Mobile-bearing knee implants
      • Cruciate retaining (CR) and posterior stabilized (PS) designs
      • High-flex implants for enhanced bending capability
   3. These are engineered for:
      • Long-term durability
      • Smooth joint movement
      • High biocompatibility
      • Reduced wear and tear

Choosing the Best Knee Replacement Implant

1. 1. • Age
      • Level of activity
      • Bone quality
      • Type of knee deformity
      • Surgeon’s preference

Benefits of Total Knee Replacement

1. 1. • Significant reduction in pain
      • Improved mobility
      • Correction of deformity
      • Long-lasting results (15–25 years depending on usage)
      • Enhanced quality of life
