It results from the progressive degeneration of the knee components, especially the <strong>articular cartilage<\/strong>. It typically affects people over 50\u201360 years old but can occasionally appear in younger individuals.<\/p>\n\n\n\n<p>As cartilage deteriorates, it loses its smooth surface and thins, leading to <strong>bone-on-bone contact<\/strong>, which causes pain during movement. Osteoarthritis progresses slowly, and symptoms worsen over time.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"gb-text\">Post-Traumatic Knee Arthritis<\/h3>\n\n\n\n<p>This form occurs after <strong>injury<\/strong>, <strong>fracture<\/strong>, or <strong>tears<\/strong> of the meniscus or ligaments, which lead to joint instability and further cartilage damage, potentially resulting in arthritis over time.<\/p>\n\n\n\n<h3 class=\"gb-text\">Rheumatoid Arthritis<\/h3>\n\n\n\n<p>Rheumatoid arthritis is a <strong>chronic autoimmune disease<\/strong> that affects multiple joints, including the knees.

However, there are treatments aimed at reducing or even eliminating pain and improving the range of motion.<\/p>\n\n\n\n<h3 class=\"gb-text\">Conservative Treatment<\/h3>\n\n\n\n<p>In the early stages of knee arthritis, and depending on the symptoms, conservative approaches may help manage the condition.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Activity modification:<\/strong> Avoid activities that trigger symptoms, such as going up and down stairs. Incorporate exercises into daily life that strengthen the muscles supporting the knee while maintaining or improving mobility. Swimming is an excellent low-impact exercise.<\/li>\n\n\n\n<li><strong>Physical therapy:<\/strong> Physiotherapy combined with muscle-strengthening exercises around the knee can reduce pain and preserve joint function.<\/li>\n\n\n\n<li><strong>Medication:<\/strong> Painkillers and non-steroidal anti-inflammatory drugs (NSAIDs) may help relieve symptoms in the early stages.<\/li>\n\n\n\n<li><strong>Injections:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Local injections of <strong>hyaluronic acid<\/strong> or <strong>cortisone<\/strong> can help.<\/li>\n\n\n\n<li>More advanced and promising biological therapies include:\n<ul class=\"wp-block-list\">\n<li><strong>Platelet-Rich Plasma (PRP) injections<\/strong><\/li>\n\n\n\n<li><strong>Stem Cell (STEM CELLS) therapy<\/strong><br>These options may reduce symptoms and slow disease progression.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p>According to the latest international guidelines by <strong>ESSKA (European Society for Sports Traumatology, Knee Surgery and Arthroscopy)<\/strong>, for early to moderate knee osteoarthritis, intra-articular <strong>PRP injections<\/strong> are considered more effective than hyaluronic acid or cortisone injections.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Dietary Supplements:<\/strong><br>Supplements containing elements found in healthy cartilage \u2014 such as <strong>glucosamine<\/strong>, <strong>chondroitin<\/strong>, <strong>collagen<\/strong>, and <strong>hyaluronic acid<\/strong> \u2014 are available on the market. The idea is that by supplying these building blocks, the body may slow down arthritis progression. While some patients report reduced pain, scientific studies have not conclusively confirmed their effectiveness, likely due to poor absorption or breakdown of these substances in the body.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"gb-text\">Surgical Treatment<\/h3>\n\n\n\n<p><strong>Surgical Treatment<\/strong><\/p>\n\n\n\n<p>When conservative treatments fail and the patient&#8217;s quality of life is significantly impacted, surgery may be recommended.<\/p>\n\n\n\n<div class=\"cta-area\">\n<div class=\"inner-container\">\n<div class=\"gb-element-e4981c7c grid-wrapper\">\n<div>\n<p>Get the Help You Need Today!<\/p>\n<\/div>\n\n\n\n<div>\n<a class=\"gb-text gb-text-b524decb gb-button\" href=\"\/en\/contact\/\">CONTACT US<\/a>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"gb-text\">Arthroscopy<\/h2>\n\n\n\n<p>For early-stage arthritis, particularly when symptoms have appeared suddenly and MRI shows meniscus tears or loose bodies, arthroscopy may be an option. It is mainly recommended for younger patients.<\/p>\n\n\n\n<h2 class=\"gb-text\">Osteotomies<\/h2>\n\n\n\n<p>In younger individuals with arthritis affecting only one compartment of the knee, an <strong>osteotomy<\/strong> can be performed. This procedure shifts the load from the damaged area to the healthy compartment by altering the knee\u2019s mechanical axis.
