What is it?<\/h3>

Knee osteoarthritis<\/strong> (also known as degenerative arthritis of the knee) is a chronic condition in which the cartilage of the knee joint gradually wears away, causing pain and restricted range of motion in the knee.<\/p>

What are the symptoms?<\/h3>
  • Knee pain<\/li>
  • Stiffness (especially in the morning or after rest)<\/li>
  • Swelling (Edema)<\/li>
  • Reduced movement<\/li>
  • Sound during movement (“crack”)<\/li><\/ul>

    What are the causes?<\/h3>
    • Age (more common in older individuals)<\/li>
    • Excess weight<\/li>
    • Previous injuries or surgeries to the knee<\/li>
    • Intense strain (e.g., sports or heavy labor)<\/li>
    • Heredity<\/li><\/ul>

      What is the treatment?<\/h3>

      Treatment is divided into conservative and surgical. Usually, conservative treatment of symptoms is initially attempted. However, if the desired result is not achieved, then surgical treatment is performed. <\/p>

      What is conservative treatment?<\/h3>
      • Weight loss<\/li>
      • Physiotherapy & exercises<\/li>
      • Painkillers \/ anti-inflammatories<\/li>
      • Knee injections: steroids, plasma (PRP), hyaluronic acid, stem cells<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

        \n\t\t\t\t\t\t\t\t\t

        What are the differences between the above injections?<\/h3>
        1. <\/u>Corticosteroid injections (cortisone)<\/u><\/li><\/ol>
          • How they work: They reduce inflammation within the joint and quickly relieve pain.<\/li>
          • Advantages: Suitable for pain “flare-ups” and quick relief.<\/li>
          • Disadvantages: The effect can last from a few weeks to several months. They do not contribute to cartilage regeneration. <\/li><\/ul>

            <\/u><\/p>

            1. <\/u>Hyaluronic acid injections<\/u><\/li><\/ol>
              • How they work: They “lubricate” the joint and improve smooth movement.<\/li>
              • Advantages: Long duration of action.<\/li>
              • Disadvantages: They do not work equally well for everyone and take a little longer to act (a few weeks). They do not contribute to cartilage regeneration. <\/li><\/ul>

                <\/u><\/p>

                1. <\/u>PRP<\/u> (Platelet-Rich Plasma) <\/u>or<\/u> Plasma<\/u><\/li><\/ol>
                  • How it works: We take blood, process it, and inject it into the knee, preserving the growth factors that will help in cartilage regeneration.<\/li>
                  • Advantages: Natural method of cartilage regeneration.<\/li>
                  • Disadvantages: Results vary from person to person.<\/li><\/ul>

                    <\/u><\/p>

                    1. Biological treatments (e.g., <\/u>stem cells<\/u>)<\/u><\/li><\/ol>
                      • How they work: The goal is tissue regeneration and cartilage repair.<\/li>
                      • Advantages: Recent research shows that they have better results in treating knee arthritis and contribute more to cartilage regeneration compared to PRP.<\/li><\/ul>
                        • Disadvantages: More expensive treatment.<\/li><\/ul>

                          What is the surgical treatment?<\/h3>
                          1. Knee Arthroscopy<\/u>:<\/li><\/ol>
                            • Joint debridement.<\/li>
                            • Attempted cartilage repair.<\/li>
                            • Treatment of concomitant meniscal tears (a common finding in knee osteoarthritis).<\/li><\/ul>
                              1. Knee Osteotomy<\/u>:<\/li><\/ol>
                                • Indicated for young patients and in cases where the knees are “bowed” or “knock-kneed”.<\/li>
                                • An attempt is made to straighten and offload the affected part of the knee.<\/li><\/ul>
                                  1. Unicompartmental Knee Replacement<\/u>:<\/li><\/ol>
                                    • Also known as Partial Knee Replacement.<\/li>
                                    • Indicated in cases where pain and arthritis are limited to the medial side of the knee.<\/li>
                                    • Involves the replacement of only the medial side of the knee with a metallic prosthesis.<\/li><\/ul>
                                      1. Total Knee Replacement<\/u>:<\/li><\/ol>
                                        • A timeless and widely adopted solution.<\/li>
                                        • Involves the complete replacement of the knee joint with metallic prostheses.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t <\/div>\r\n <\/div>\r\n \t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
