It is the consequence of r<strong>epetitive stress on the patellar tendon<\/strong>. Repetitive stress on the tendon causes<strong> acute tendinitis<\/strong> in the early stages. <strong>Acute tendinitis<\/strong> is the pain caused by having done excessive exercise that we are not trained for. In this phase, <strong>tendinitis<\/strong> is usually fully reversible. It usually responds well to sports rest, local cold and taking oral anti-inflammatories.<\/p>\n<p>The problem comes when this injury becomes chronic. In this phase there is no acute inflammation, small <strong>tears<\/strong> are produced <strong>in the tendon<\/strong>. Faced with these tears, the body tries to repair them. Most of the time it does so with abnormal scar tissue that alters the correct structure of the tendon. This causes a vicious cycle, where pain continues to perpetuate, more abnormal repair and we start over.<\/p>\n<p>For this reason, in this phase, the patient does not usually respond to the previous treatment. There is no longer an inflammatory process, and in this case, rest only worsens the situation. And so we add a component of muscular atrophy due to the sports stop while the <strong>tendon injury<\/strong> persists. Therefore, when returning to activity after 2-3 weeks of inactivity, there is more muscle atrophy and the same (or more)<strong> abnormal reparative tendon injury<\/strong>. As tears multiply, they cause pain due to chronic inflammation and weakening of the tendon.<\/p>\n<p>The area that is most commonly affected in <strong>patellar tendinitis <\/strong>is the so-called lower pole of the patella. That is, the area where the <strong>patellar tendon<\/strong> \u201chooks\u201d to the patella. In fact, it affects this area more than the <strong>patellar tendon<\/strong> itself. For this reason, we technically call this condition <strong>patellar enthesitis<\/strong>.<\/p>\n<p>If you try to ignore the pain and persist with physical activity \u201cholding it\u201d, it can lead you to increase this vicious circle and make it increasingly difficult to solve the underlying problem.<\/p>\n<blockquote>\n<h4><em><strong><a href=\"http:\/\/www.barnaclinic.com\/profesionales\/91\/sergi\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-151 size-full\" title=\"Sergi Sastre\" src=\"http:\/\/www.barnaclinic.com\/blog\/traumatologia-deportiva\/wp-content\/uploads\/sites\/3\/sastre-sergi.png\" alt=\"Sergi Sastre - Condromalancia de r\u00f3tula\" width=\"90\" height=\"90\" \/><\/a><\/strong><\/em><\/h4>\n<h4>\u201cIf you try to ignore knee pain and persist with physical activity &#8216;holding it in&#8217;, it can make it increasingly difficult to fix patellar tendinitis\u201d<\/h4>\n<p><a href=\"https:\/\/www.barnaclinic.com\/en\/professionals\/91\/sergi\" target=\"_blank\" rel=\"noopener noreferrer\">Dr. Sergi Sastre<\/a>\u00a0\u2013 Traumatologist expert in Sports Medicine<\/p><\/blockquote>\n<h2>RISK FACTORS FOR PATELLAR TENDINITIS<\/h2>\n<p><strong>Several factors can contribute to the development of patellar tendinitis, <\/strong>including:<\/p>\n<ul>\n<li><strong><u>Specific physical activity<\/u><\/strong>: Running and jumping are the factors most commonly associated with <strong>patellar tendinitis<\/strong>. Sudden increases in the intensity or frequency with which you perform the activity also increase the <strong>stress on the tendon<\/strong>. Changing running shoes can also play a role. Poor training planning or overtraining can contribute to it. In fact, this factor is often the <strong>most common cause of patellar tendinitis<\/strong>.<\/li>\n<li><strong><u>Weak muscles in the legs<\/u><\/strong>: The weakness of the thigh muscle (quadriceps in particular) can increase the <strong>stress on the patellar tendon<\/strong>, causing the tendon to work \u201coverloaded\u201d.<\/li>\n<li><strong><u>Muscle imbalance<\/u><\/strong>: The imbalance between agonist and antagonist muscles (quadriceps and hamstrings) can cause that, if some leg muscles are much stronger than others, the stronger muscles pull with more intensity on the <strong>patellar tendon<\/strong>. This imbalance can be one of the <strong>causes of patellar tendinitis<\/strong>.<\/li>\n<li><strong><u>Chronic diseases<\/u><\/strong>: Some diseases interrupt blood flow to the knee, which weakens the tendon. Some diseases that could influence this are: <a href=\"https:\/\/www.clinicbarcelona.org\/en\/assistance\/diseases\/chronic-kidney-failure\" target=\"_blank\" rel=\"noopener noreferrer\">kidney failure<\/a>, <a href=\"https:\/\/www.barnaclinic.com\/en\/specialties\/28\/enfermedades-autoinmunes\" target=\"_blank\" rel=\"noopener noreferrer\">autoimmune diseases<\/a>, such as <a href=\"https:\/\/www.clinicbarcelona.org\/en\/assistance\/diseases\/lupus\" target=\"_blank\" rel=\"noopener noreferrer\">lupus<\/a> or <a href=\"https:\/\/www.clinicbarcelona.org\/en\/assistance\/diseases\/rheumatoid-arthritis\" target=\"_blank\" rel=\"noopener noreferrer\">rheumatoid arthritis<\/a>, and metabolic diseases such as diabetes. The latter factor is a less common <strong>cause of patellar tendinitis<\/strong>. What is proven is that <a href=\"https:\/\/www.barnaclinic.com\/en\/smoking\/\" target=\"_blank\" rel=\"noopener noreferrer\">smokers<\/a>, having an alteration in blood capillarity, have a worse repair and healing process, so in these patients the healing process is much more difficult.<\/li>\n<\/ul>\n<h2>PREVENTION OF PATELLAR TENDINITIS<\/h2>\n<p>To prevent the<strong> progression of patellar tendinitis <\/strong>and avoid chronifying the process, we can adopt these measures:<\/p>\n<h4>5 tips to prevent patellar tendinitis<\/h4>\n<ol>\n<li><strong><u>Do not play when you are in pain<\/u><\/strong>. As soon as you notice <strong>pain in your knee<\/strong> from exercising, ice the area and rest. Until you no longer have <strong>pain in your patella<\/strong> or knee, avoid activities that put <strong>stress on your patellar tendon<\/strong>. It would be about acting in the initial phases of <strong>tendinopathy<\/strong>, when it is more easily reversible.<\/li>\n<li><strong><u>Strengthen your muscles<\/u><\/strong>: Strong thigh muscles are better able to overcome the strain that <strong>patellar tendinitis <\/strong>can cause. Eccentric exercises are especially useful for tendon strengthening. They consist of lowering the leg very slowly after having extended the knee.<\/li>\n<li><strong><u>Improve your technique<\/u><\/strong>: To ensure that you use your body correctly, consider taking classes or getting professional instructions. Especially when you start a new sport or when you want to progress in a certain sport.<\/li>\n<li><strong><u>Plan your training and rest periods<\/u><\/strong>: Having a training plan, considering breaks, is essential to avoid overloading and overtraining.<\/li>\n<li><strong><u>Complement with specific exercises for muscle and tendon stretching<\/u><\/strong>: To avoid <strong>tendon injuries<\/strong> or <strong>muscle injuries<\/strong>, it is essential to carry out the stretching pattern. Introduce eccentric exercises.<\/li>\n<\/ol>\n<h2>TREATMENT OF PATELLAR TENDINITIS<\/h2>\n<h4>Initial stages of patellar tendinitis<\/h4>\n<p>As I have indicated previously, in the initial phases the <strong>treatment of patellar tendinitis<\/strong> is reduced to: <strong>resting<\/strong>, applying <strong>ice to the area<\/strong> to reduce pain and inflammation and the application of special <strong>elastic bandages<\/strong>. On a doctor\u2019s guide, <strong>certain anti-inflammatories can be taken<\/strong>.<\/p>\n<p><strong>Eccentric rehab exercises and massages<\/strong> may also be helpful. These exercises will help strengthen your knee, quadriceps and calf muscles.<\/p>\n<h4>Evolved phases of patellar tendinitis<\/h4>\n<p>For the <strong>treatment of patellar tendinitis<\/strong> in more advanced stages, certain physiotherapy techniques may be necessary. These exercises are aimed at \u201cdestroying\u201d the newly created anomalous tissue. This tissue that tries to heal the tendon injury does nothing more than perpetuate the injury.<\/p>\n<h4>Chronic phases that do not respond to treatment<\/h4>\n<p>If all these <strong>patellar tendinitis treatment<\/strong> techniques do not work,<a href=\"https:\/\/www.fcbarcelona.com\/en\/football\/first-team\/noticias\/2152235\/marc-ter-stegen-sometido-a-un-procedimiento-terapeutico-en-el-tendon-rotuliano\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"text-decoration: underline;\"> just like in the case of the FC Barcelona goalkeeper, Marc-Andr\u00e9 Ter Stegen<\/span><\/a>, surgery may be necessary. In these cases, a <strong>surgical intervention is performed to remove this abnormal tissue and promote the creation of tendon tissue with the correct characteristics<\/strong>. Currently, <a href=\"https:\/\/www.barnaclinic.com\/en\/professionals\/91\/sergi\" target=\"_blank\" rel=\"noopener noreferrer\">specialists dedicated<\/a> to <a href=\"https:\/\/www.barnaclinic.com\/en\/orthopaedic-trauma\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>sports traumatology<\/strong><\/a> perform <strong>patellar tendinitis surgery<\/strong> with a combination of <a href=\"https:\/\/www.barnaclinic.com\/blog\/traumatologia-deportiva\/en\/2020\/11\/09\/ansu-fatis-meniscus-injury\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>arthroscopy<\/strong><\/a> and ultrasound. This combination allows us to act precisely only on the abnormal tissue. In all cases, <strong>patellar tendinitis surgery<\/strong> must be complemented with a specific muscle strengthening program.<\/p>\n<hr \/>\n<div id=\"estoy-interesado\" class=\"destacat-site\">\n<h1 style=\"padding-left: 15px; padding-right: 15px;\" align=\"center\"><span style=\"color: white;\">WANT TO CONTACT DR.
