It occurs where the knee connects with the lower thigh bone or femur. <strong>Runner\u2019s knee is <\/strong><strong><em>not<\/em><\/strong><strong> the result of tissue damage<\/strong>.<\/p>\n\n\n\n<p>When you bend or straighten your knees, the kneecap or patella slides back and forth inside a grove at the top of the femur. This is called the patellar groove.<\/p>\n\n\n\n<p><strong>Runner\u2019s knee occurs when your kneecap moves off to the side<\/strong> when you run or exercise instead of remaining in its grove.<\/p>\n\n\n\n<p>It\u2019s important to remember that <strong>this isn\u2019t just one condition<\/strong>, but a broad term used to describe knee pain after running. Conditions that may contribute to runner\u2019s knee include patellofemoral malalignment, iliotibial band syndrome, chondromalacia patella, and anterior knee pain syndrome.<\/p>\n\n\n\n<p>Also, despite its name, <strong>it\u2019s not only runners who can have it<\/strong>. But it commonly develops in runners as a result of the constant strain put on the kneecap and nearby structures, and especially as a result of overtraining or certain gaits.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"patellofemoral-pain-syndrome-vs-patellar-tendonitis\"><\/span>Patellofemoral Pain Syndrome vs Patellar Tendonitis<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Unlike runner\u2019s knee, patellar tendonitis causes pain under the kneecap, where the patellar tendon meets the bone of the shin. It may occur as a result of strain on the tendon and tends to get better with rest.<\/p>\n\n\n\n<p>As a runner, you may develop either or both conditions. But knowing the difference between them is important as it will help you treat the pain accordingly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"causes-of-runners-knee\"><\/span>Causes of Runner&#8217;s Knee<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21292488\/\" target=\"_blank\" rel=\"noreferrer noopener\">Research<\/a> indicates that mature female runners between the age of 40 and 60 have more internal rotation in the knee and higher movement inside out of the hindfoot compared to female runners aged 18 to 24.
