Most often, this involves the medial compartment, but it can also involve the lateral or patellofemoral compartment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike a total knee replacement, which replaces the entire knee, a partial knee replacement preserves the ligaments, healthy cartilage, and much of the natural anatomy. It better respects the biomechanics of the joint, promoting faster recovery and a joint sensation closer to that of the original knee.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Coulin offers this option whenever the conditions are right, as it is a modern, conservative and effective solution for treating localized osteoarthritis of the knee.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div style=\"max-width: 350px;\"><blockquote class=\"instagram-media\" data-instgrm-permalink=\"https:\/\/www.instagram.com\/reel\/DX1C7SBIAtI\/?utm_source=ig_embed&amp;utm_campaign=loading\" data-instgrm-version=\"14\" style=\" background:#FFF;

It is particularly indicated when the following conditions are present:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A&nbsp;<strong>localized osteoarthritis<\/strong>&nbsp;single compartment (internal, external or patellofemoral).<\/li>\n\n\n\n<li>A&nbsp;<strong>ligament stability<\/strong>&nbsp;preserved, in particular a <a href=\"https:\/\/sosgenougeneve.ch\/ligament-croise-anterieur-lca\/\" data-type=\"link\" data-id=\"https:\/\/sosgenougeneve.ch\/ligament-croise-anterieur-lca\/\" target=\"_blank\" rel=\"noopener\">anterior cruciate ligament (ACL)<\/a> intact.<\/li>\n\n\n\n<li>A&nbsp;<strong>satisfactory mobility<\/strong>&nbsp;of the joint.<\/li>\n\n\n\n<li>A&nbsp;<strong>correct knee alignment<\/strong>&nbsp;or easily correctable.<\/li>\n\n\n\n<li>Moderate to vigorous activity, without excessive overload.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This surgery can be suitable for both young patients, wishing to delay a total prosthesis, and older patients, seeking a rapid recovery and a quality functional return.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the advantages of a partial denture?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Compared to a total prosthesis, a unicompartmental prosthesis offers several advantages:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>An intervention&nbsp;<strong>less invasive<\/strong>, with a reduced incision.<\/li>\n\n\n\n<li>Preservation of healthy knee structures (ligaments, preserved cartilage).<\/li>\n\n\n\n<li>A&nbsp;<strong>faster recovery<\/strong>&nbsp;with an earlier return to autonomy.<\/li>\n\n\n\n<li>A more natural joint sensation, with a fluid gait and less apprehension.<\/li>\n\n\n\n<li>Less bleeding, post-operative pain and risk of complications.<\/li>\n\n\n\n<li>This intervention facilitates a possible future revision, as it leaves a large part of the joint intact.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thus, partial knee replacement makes it possible to combine effectiveness, safety and preservation of joint function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How does the procedure with Dr. Coulin take place ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Partial prosthesis placement is performed under local or general anesthesia. It is a minimally invasive surgery, using small incisions and maximizing tissue preservation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On average, the procedure lasts about an hour. The patient is up within a few hours and usually returns home within 48 hours.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Coulin uses modern surgical guidance techniques and, when necessary,&nbsp;<a href=\"https:\/\/coulinmedical.com\/en\/planification-3d-en-chirurgie\/\" data-type=\"post\" data-id=\"22979\">3D imaging-assisted planning<\/a>This precision guarantees optimal positioning of the implant, perfectly adapted to the morphology and biomechanics of each patient&#039;s knee.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the post-operative consequences ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The recovery after a partial knee replacement is generally simple and quick:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Weight bearing is permitted immediately after surgery.<\/li>\n\n\n\n<li>The gradual resumption of walking takes place in the following days.<\/li>\n\n\n\n<li>Rehabilitation begins very early, with a targeted program to regain mobility, strengthen muscles and retrain proprioception.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most patients return to an active life quickly, with a gradual return to sporting activities between 2 and 3 months, depending on the profile and individual motivation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What results can you expect ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In well-selected patients, partial dentures offer very satisfactory results:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A clear and lasting reduction in pain.<\/li>\n\n\n\n<li>A significant improvement in movement quality.<\/li>\n\n\n\n<li>A feeling closer to the natural knee than with a total prosthesis.<\/li>\n\n\n\n<li>A lifespan comparable to total prostheses, in the right indications.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Satisfaction rates are high and most patients regain smooth mobility, complete autonomy and good confidence in their joint.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A tailor-made approach, on a case-by-case basis<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The choice between a partial or a total prosthesis always depends on a complete assessment: analysis of symptoms, precise imaging and patient expectations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Coulin favors preserving natural structures whenever possible. However, he only recommends a partial denture when it provides a reliable, durable, and long-term solution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Do you suffer from localized osteoarthritis of the knee?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dr. Coulin will see you for a consultation in Geneva to assess your situation, analyze your examinations and determine if a partial prosthesis may be the ideal solution in your case.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to personalized care and cutting-edge surgical techniques, he will guide you towards a rapid, secure and lasting recovery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>When osteoarthritis only affects one compartment of the knee, the solution may be less invasive than a total knee replacement.<br \/>\nA partial knee replacement, also called a unicompartmental knee replacement, preserves a large part of the natural knee.
