The sports most at risk are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>football,<\/li>\n\n\n\n<li>skiing,<\/li>\n\n\n\n<li>basketball,<\/li>\n\n\n\n<li>rugby,<\/li>\n\n\n\n<li>handball.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These sports involve pivoting, jumping, landing, and sudden acceleration, all of which put a lot of strain on the knee. Injury can result from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>with a sudden twisting movement,<\/li>\n\n\n\n<li>unexpected braking or change of direction,<\/li>\n\n\n\n<li>from a fall,<\/li>\n\n\n\n<li>or direct contact on the knee.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Certain factors increase the risk of ACL rupture:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>a lack of physical preparation,<\/li>\n\n\n\n<li>muscle fatigue,<\/li>\n\n\n\n<li>an imbalance between quadriceps and hamstrings,<\/li>\n\n\n\n<li>or an inappropriate technique during sporting movements.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the symptoms of an ACL tear?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A rupture of the <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<\/a>&nbsp;often manifests itself through a brutal and striking feeling:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>a cracking or tearing sensation at the time of trauma,<\/li>\n\n\n\n<li>immediate acute pain,<\/li>\n\n\n\n<li>rapid swelling of the knee (hemarthrosis),<\/li>\n\n\n\n<li>instability, giving the impression that the knee \u201cgives way\u201d, particularly on uneven ground or during rotations.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These symptoms should lead to a specialist consultation in order to confirm the diagnosis and avoid complications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Prevention of ACL tears<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">ACL injury prevention relies on targeted physical preparation. Dr. Coulin recommends:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A&nbsp;<strong>muscle strengthening<\/strong>&nbsp;quadriceps, hamstrings, glutes and core muscles,<\/li>\n\n\n\n<li>a work of&nbsp;<strong>proprioception<\/strong>&nbsp;and movement perception, to improve coordination and responsiveness,<\/li>\n\n\n\n<li>a suitable warm-up before any effort,<\/li>\n\n\n\n<li>and one&nbsp;<strong>gradual recovery<\/strong>&nbsp;after an injury to prevent recurrence.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specific prevention programs already exist in certain sports clubs, significantly reducing the risks of ACL tears.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to diagnose an ACL tear?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The diagnosis is based on several stages:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Clinical examination: the specialist assesses knee stability using specific tests (Lachman, pivot shift\u2026).<\/li>\n\n\n\n<li>MRI of the knee: it allows direct visualization of the anterior cruciate ligament and detection of any associated lesions (meniscus, cartilage).<\/li>\n\n\n\n<li>X-ray: useful to rule out a fracture or associated bone injury.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A rapid and accurate diagnosis allows the most appropriate treatment to be implemented.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the possible treatments for a ruptured anterior cruciate ligament?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The choice of treatment depends on the patient&#039;s age, activity level and expectations.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Conservative treatment<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In sedentary or non-athletic patients, ACL tears can sometimes be managed without surgery. Treatment includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>intensive rehabilitation,<\/li>\n\n\n\n<li>muscle strengthening,<\/li>\n\n\n\n<li>adaptation of activities to limit stress on the knee.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>ACL Surgery<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In young people, athletes, or in cases of persistent instability, anterior cruciate ligament (ACL) reconstruction is recommended. The operation involves replacing the torn ACL with a tendon graft, most often taken from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the patellar tendon,<\/li>\n\n\n\n<li>the hamstrings,<\/li>\n\n\n\n<li>or sometimes the quadriceps tendon.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The intervention is carried out under&nbsp;<a href=\"https:\/\/coulinmedical.com\/en\/arthroscopie-une-chirurgie-mini-invasive\/\" data-type=\"post\" data-id=\"22837\">arthroscopy<\/a>, with small incisions and equipment adapted to the patient&#039;s morphology.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the after-effects after ACL surgery?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Rehabilitation is a key step to success. It begins quickly after surgery and has several goals:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>restore knee mobility,<\/li>\n\n\n\n<li>strengthen the muscles,<\/li>\n\n\n\n<li>retrain proprioception,<\/li>\n\n\n\n<li>regain a smooth gait.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The resumption of sport is happening gradually, between&nbsp;<strong>6 and 12 months<\/strong>, depending on the discipline practiced and the patient&#039;s progress.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Expert and personalized support in Geneva<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A ruptured anterior cruciate ligament should never be ignored, as it exposes the patient to risks of meniscal tears or early-onset osteoarthritis. Dr. Coulin takes a comprehensive approach: accurate diagnosis, appropriate treatment (conservative or surgical), and individualized rehabilitation follow-up.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Do you think you may have torn your ACL?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">THE <a href=\"https:\/\/coulinmedical.com\/en\/dr-coulin-chirurgien-orthopedique\/\" data-type=\"page\" data-id=\"15841\">Dr. Coulin<\/a> We welcome you to Geneva to make a clear diagnosis and build, with you, a tailor-made treatment plan \u2014 whether it is to regain the stability needed for sport, work or simply a comfortable daily life.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>A cracking sound, a sudden pain, a feeling of the knee giving way?
