Cruciate ligament

Common leg injuries are some of the most inhibiting and destructive injuries that can occur. Countless studies have been conducted to reveal if there is a way to possibly prevent these occurrences. Symptoms often develop from everyday usage, overuse, or an injury. Leg injuries are most likely to occur from sports activities. Most of these leg injuries in children and teens occur from playing sports or falls. The risk for these types of injuires increase during contact sports and high-speed…

The summer of my junior year of high school I had the opportunity to shadow a variety of medical professionals. One of these was an orthopedic surgeon, and during the time I spent watching his surgeries, I got the chance to witness two Total Knee Arthroscopies (TKAs). For my biomedical product, I chose to research a total knee prosthesis. This prosthetic has an old and very diverse history that centers mostly around the 1970s, but today has become a multibillion dollar industry with millions of…

Don’t Tear it Female athletes on average are 3.5 times riskier for non-contact Anterior Cruciate Ligament injuries compared to males (Ireland). The Anterior Cruciate Ligament (ACL) in the knee is likely to tear if a person lands wrong on it, which can be heard or felt by a pop or snap. The Anterior Cruciate Ligament is one of four ligaments that attach the femur, tibia and fibula. There are many sports that an ACL tear is more likely to occur in, such as, basketball, soccer and skiing. People…

Grade one sprains happen when the ligament is slightly damaged. The ligament has been slightly stretched and there will be pain, but is still able to help keep the knee stable. Grade two spains stretches the ligament to the point it becomes loose and this is often referred to a s a partial tear. Grade three sprain is the type that most people typically hear about. This sprain is a complete tear of the ligament, it has been split into two pieces and the knee is unstable at…

towards this injury. The reason for this is because girls are more susceptible to knee injuries (Quinn Sports Medicine). The structures damaged through this injury are the most necessary part of the knee. One ligament that is injured through this process is the anterior cruciate ligament, or otherwise known as the ACL. This part of the unhappy triad is to be considered the most serious of the structures damaged. This is because the ACL provides stability to the entire knee. It can also be very…

connected through ligaments, our knees have four main ligaments. Two of the ligaments in our knee is the medial collateral ligament (MCL), this ligament prevents valgus (force from the outside of the knee, forcing the knee inward) stress to the knee and lateral collateral ligament(LCL), this ligament prevents varus (force from the inside of the knee,forcing the knee outward) stress to the knee. Another ligament in the knee is the posterior cruciate ligament (PCL), this ligament prevents…

patellofemoral joint. Internal instability of the knee refers to the damage of a variety of structures within the knee, including meniscal cartilage tears and loose bodies. Higher knee joint laxity may be an indication of an increased risk of anterior cruciate ligament (ACL) injuries. The patient will present with soreness and instability of the knee during an activity. The knee examination should comprise an assessment of the posture and also the lower extremity alignment. The alignment at the…

includes muscles, joints, ligaments, and bones. Exercise science is the study of human movement and how the body responds and adapts to physical activity, health, exercise, and sports. Often times people who are in need of this type of rehab are athletes, people who are constantly working out, and the elderly. Athletes being the most common who seek rehab. When it comes to injuries there’s an enormous list of things that can occur, such as the tearing of ligaments, broken bones,…

Imagine what it would be like to be told you would never be able to partake in the sport you loved again. If athletes with torn anterior cruciate ligaments do not follow a strict rehabilitation plan, that could be the case for them. In most scenarios, a tear in the anterior cruciate ligament is highly repairable; however, if the steps in the rehabilitation process are not followed closely and carefully, it could easily lead to further injury and a longer recovery process. An athlete never…

as a shock absorber when pressure is applied across the knee. If the meniscus was taken away, the knee would experience 50% more stress pressure. The second function of the meniscus is to stabilize the anterior cruciate ligament. The most common injuries to the anterior cruciate ligament are acute injuries to the medial meniscus. Acute twisting injuries are the most common caused from sports-related incidents. Scenarios of incidents that are common involved one foot staying on the ground…
