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

<!-- wp:paragraph -->
<p>Partial medial knee replacement is a surgery to replace only the medial part of your damaged knee. It is also called unicompartmental knee replacement. 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, medial and patellofemoral compartments. The inside part of your knee is the medial compartment of the knee. It consists of a medial collateral ligament (MCL).&nbsp;</p>

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

<!-- wp:paragraph -->
<p>Aging and joint conditions such as osteoarthritis cause breakdown of the cartilage of your inner knee leading to pain and inflammation which may not respond to pain medications or non-surgical treatment and may need surgery. Damage to the medial side of your knee may also cause knee stiffness requiring surgery.&nbsp;</p>

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

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

<h2>Partial Medial 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 in the front and medial side of the knee and an arthroscope is inserted to view the surgical area.&nbsp;</li><li>The damaged cartilage at the medial portion of your knee is debrided. Some amount of bone may also be removed.&nbsp;</li><li>Metal components with a spacer in between are placed at the inner side of your knee to allow smooth gliding.&nbsp;</li><li>The incisions are closed and covered with a dressing.</li></ul>
