Collateral Ligament Injury Case Study
Male wrestler, from high school league, arrives at the PT clinic with an MD prescription for treatment. He was diagnosed with a grade II MCL knee sprain yesterday.
A medial collateral ligament (MCL) is known as common knee ligament injury, additional with low-grade sprains often going unreported. MCL sprain often occurs for an athletic population for both contact and non-contact sports athletes. There are two different parts to MCL; superficial MCL and deep MCL. There are no firm attachments or definable bursa between a superficial MCL and underlying deep MCL. A superficial MCL is the largest structure over medial aspect of the knee, which have one femoral and two tibial attachments. Femoral attachment of the superficial MCL is not located directly to the medial epicondyle, but is centered in a depression proximal and posterior. However, tibial attachments have two different attachment sites—distal and posterior. Tibial …show more content…
Takakura et al5 done a study on thirteen male rats’ MCL to reveal benefits of ultrasound. The MCL of one knee was exposed to LIPUS (1.5MHz, 30mW/cm2) every day for twenty minutes after the MCL surgery, while other knee was left unexposed. The rats were divided into two groups; one group of rats got killed after 12 days and other after 21 days. After 12 or 21 days, the rats were killed after their surgery to test ultimate load, stiffness, and energy absorption level of both treated and untreated MCL. According to Takakura et al,5 the rats that were treated were significantly superior in ultimate load, stiffness, and energy absorption, unlike the untreated MCL specimens. Additionally, the mean diameter of the fibrils was significantly larger in treated ligaments than untreated ligaments. But, there were no signs of significant differences in specimens obtained 21 days after the surgery due to quick natural healing

    Acl Tears Research Paper

    This article is explaining how bad ACL tears truly are and why they are difficult to heal. An acl cannot heal itself, thus making it difficult to try and heal it. Many times when someone tears their ACL, their MCL is also torn. But the ACL does not reknit itself after an injury while the MCL does. Harvard Medical School doctors researched on a better way to heal an acl tear and they learned that using blood clots is a good method. When an MCL is torn, blood clots are created automatically which will help heal the tissue, but this does not happen in ACLs. So these doctors tried to repair ACLs by doing the blood clot scaffolding. They tested these methods on pigs and it was successful. It took about twelve months for the pigs to be as…

    The Anterior Cruciate Ligament (Acl): Injuries and How to Prevent and Treat Them

    The Anterior Cruciate Ligament (ACL) is one of the two cruciate ligaments of the knee, the other being the Posterior Cruciate Ligament (PCL). These ligaments are the stabilizers of the knee. The ACL is a strip of fiber tissue, which is located deep inside the knee joint. It runs from the posterior side of the femur (thigh bone) to the anterior side of the tibia (shin bone) deep inside of the knee. The ligament is a broad, thick cord the size of a person 's index finger. It has long collagen strands woven together in a fashion that permits forces of up to 500 pounds to be exerted. The function of the ACL is to prevent the tibia from moving in front of the knee and femur. The ACL also prevents hyperextension (or extreme stretching of the knee backward) and helps to prevent rotation of the tibia.…

    Career Ending Injuries In John Grisham's 'Bleachers'

    Now this surgery is a very difficult and long process operation. Because there are three ligaments ruptured you have options on how they can be repaired. For the ACL, your options for the graft are the patellar tendon autograft, hamstring tendon autograft, quadriceps tendon autograft, and allografts. The reason these options are considered is because in the past doctors used to just sew the ACL back together, but didn’t have a high recovery rate. For the meniscus you have three options. Meniscectomy, which is the removal of the torn section of the meniscus, a suture repair of the torn section, or an implantation of a cadaver meniscus. The MCL is very unique, unless it is a very severe tear, the MCL will heal on its own once the torn ligaments are repaired. The knee will once again be stabilized after surgery and the MCL will begin to heal. This surgery is arthroscopic meaning that it is done using a small camera inserted into your joint area with a picture being presented on a screen to help surgeons see. The most crucial damage of the ligaments is the ACL and does require reconstructive…
