<h2>What is Partial Lateral Knee Replacement?</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Partial lateral knee replacement is a surgery to replace only the lateral part of your damaged knee. It is also called unicompartmental knee replacement.&nbsp;</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>The knee is one of the largest and complex joints in your body. The joint is connected to your thigh bones and bones of the lower leg by various ligaments. The knee joint is made of three compartments. The lateral, the medial and the patellofemoral compartment. The outside part of the knee is the lateral compartment. It consists of a Lateral Collateral Ligament (LCL).&nbsp;</p>

<h2>Indications for Partial Lateral Knee Replacement</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Lateral knee replacement is less common when compared to a medial and total knee replacement. Aging and joint conditions such as osteoarthritis cause breakdown of the cartilage leading to pain and inflammation which may not respond to pain medicine or non-surgical treatment and may require surgery. Lateral knee replacement is necessary when your knee bends outwards.&nbsp;</p>

<h2>Diagnosis</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Your doctor physically examines your knee by performing specific movements to assess the problem. The exact location and severity of the pain are essential to identify the type and extent of the damage. Your doctor will also take your medical history and may order an X-ray or CT-scan or MRI to confirm the diagnosis.&nbsp;</p>

<h2>Preparation for Surgery</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>Talk to your doctor about the medicines you are taking and those you should stop taking prior to the procedure. Inform your doctor if you are allergic to any medicines or anesthesia.&nbsp;</p>

<h2>Partial Lateral Knee Replacement Procedure</h2>
<!-- /wp:heading -->

<!-- wp:list -->
<ul><li>Surgery is performed under general anesthesia or spinal anesthesia. The surgical procedure involves the following steps:</li><li>You are positioned to lie on your back (supine position).&nbsp;</li><li>The surgery is usually performed by arthroscopy. An arthroscope is a narrow tube with a tiny video camera on one end. The structures inside the knee are visible to your surgeon on a monitor in the operating room.</li><li>A few small incisions are made at the lateral side of the knee and an arthroscope is inserted to view the surgical area.</li><li>The damaged cartilage at the lateral portion of your knee is debrided. Some amount of bone may also be removed.&nbsp;</li><li>Debridement of some part of the distal femoral portion may be involved.&nbsp;</li><li>Metal components with a spacer in between are replaced at the lateral side of your knee to allow smooth gliding.&nbsp;</li><li>The incisions are closed and covered with a bandage.&nbsp;</li></ul>
