This literature review is to examine just how females are more susceptible to knee injuries, especially having to do with the anterior cruciate ligament. Knee injuries are always prevalent in injuries. Through studies and research, it has been discovered that these types of knee injuries occur more frequently in females, especially an anterior cruciate ligament injury. In order to understand some of the biological reasons as to why the ACL is more commonly injured in females, one must take an in-depth look at the knee anatomy.
The knee joint is the largest joint in the body, along with one of the most easily injured. The four main components of the knee are the bones, cartilage, ligaments, and tendons. The three bones that make up the knee joint are the femur, tibia, and patella. The two types of cartilage are the meniscus and the articular cartilage. The articular cartilage covers the ends of the femur and tibia, along with the back of the patella. This type of cartilage helps the knee glide smoothly across all the bones as you bend or straighten your leg. The meniscus is made of two pieces. One is shaped like a “C”. The other piece is shaped like an “O.” These two pieces act as shock absorbers between the femur and tibia. The meniscus is tough and made to help cushion and keep the joint stable. Another major part of the knee joint anatomy is the ligaments. Ligaments are how bones are connected to other bones. There are four main ligaments found in the knee. The four ligaments are divided into two types called the collateral and cruciate ligaments. The collateral ligaments are found on the inside and outside of the knee. The medial collateral ligament, or MCL, is found on the inside. The lateral collateral ligament, or LCL, is f...

...males. When a patellar tendon graft was used, the success rates between males and females were about the same. If a female athlete tears their ACL while they still plan to return to play, it is harder for them to return to play. The recovery time for a male is five to six months post-surgery. For a female, recovery time from an ACL tear is six to seven months.
So it has been concluded and agreed upon that females are at much more of risk for knee injuries, especially that of an anterior cruciate ligament injury. So the question is, can we prevent this from happening and how? I would have to say that in my opinion, ACL injuries cannot be stopped whether male or female. Many of the factors that contribute to biological reasons that cannot be helped. There are some preventative measures that can be taken. Although there is no universally accepted ACL prevention program.
The knee joint is formed by the articulation of the distal end of the femur and the proximal end of the tibia. The fibula is only involved to the extent that it serves as an attachment site for connective tissue. In this paper, the anatomy of the joint will be discussed.
The incidence and prevalence rate of anterior cruciate ligament (ACL) injuries in female athletes continues to increase over time (Prodromos, Han, Rogowski, Joyce, & Shi, 2007). With the growing rate in the amount of young women participating in sports, data has shown that the rate of ACL injury increases linearly with this participation ("The Relationship Between Static Posture and ACL Injury in Female Athletes," 1996). This epidemic of ACL injuries in female athletes, young or old, continues to be problematic in the athletic world. This problem not only affects the athlete themselves, but also the coaches and the sports medicine community.
Tearing the ACL is now considered an epidemic in the United States over 100,000 recorded incidences are reported each year (Moeller). While such a finding may be good for orthopedic doctors and surgeons, this is not good for millions of athletes’ competing these days in high intensity sports. This is especially a problem for female athletes who are two to four times more likely to tear their ACL than men (Moeller). This is one of the biggest mysteries about ACL tears is the difference between the number of injuries seen in women and men. Women tend to tear there ACL far more frequently then men. While not everyone agrees that gender itself is the source of the problem, evidence is growing that females are learning too late that participating in sports can also become the first step to ruining an active lifestyle.
The most common knee injury in sports is damage to the anterior cruciate ligament (ACL) through tears or sprains. “They occur in high demand sports that involve planting and cutting, jumping with a poor landing, and stopping immediately or changing directions” (University of Colorado Hospital). The ACL is a ligament that runs diagonally in the middle of the knee and found at the front of the patellar bone. Its function involves controlling the back and forth motion of the knee, preventing the tibia from sliding out in front of the femur, and providing rational stability to the knee. Interestingly, women are more prone to ACL injuries than men. The occurrence is four to six times greater in female athletes.
Al Toon, father of Saints receiver Nick Toon, was forced to leave professional football after sustaining nine concussions in eight years of professional football. Football is one of the most dangerous games. As the years go on, more and more rules are being written to prevent the danger, but danger is the nature of the game. Most of these rules are for the protection of the players, but there are times when injuries can be a good thing. The Philadelphia Eagles were 3-5 to start the year, but Michael Vick was injured and the backup quarterback led the team to be 10-6, win the division, and almost beat the New Orleans Saints in the playoffs. "About 1.7 million Americans suffer a traumatic brain injury (TBI) every year, about three-quarters of them mild TBIs, or concussions" (Clemmitt). Traumatic Brain Injuries are used as the main form of evidence in Richard Cohen's claim that the end of the NFL is near, and quite frankly, his argument is pretty solid.
In November of 2010, I was playing basketball in the fifth game of my senior season. It was just like any other game. However, I would soon find out otherwise. It was late in the game; I drove into the lane and got fouled hard. I was knocked so off-balance that I speared the floor with my knee. As soon as my knee hit the floor I heard a “snap” that I will never forget for the rest of my life. Little did I know at the time, that would be the last shot of my high school basketball career. Not long after my injury, I consulted a doctor. After getting an x-ray and an MRI, the doctor informed me that I had completely torn my ACL and would need to have surgery. An ACL tear can be a very devastating injury. The anterior cruciate ligament (ACL) is one of the four major ligaments within the knee. The ACL is one of the most commonly injured ligaments, injured by an estimated 200,000 patients each year. Of the 200,000 annual ACL injuries, surgery is performed in approximately 100,000 cases. There are many types of reconstructive surgery on the ACL. However, there is an alternative to surgery in the form of physical therapy.
It can mean losing the chance to get that scholarship for young athletes, and it can also mean the end of those million dollar paychecks for those who have gone professional. A torn ACL can result in numerous surgeries, months of vigorous exercise and rehabilitation, and a sufficient amount of pain. It requires complete patience, as pushing too hard can result in further, more painful injuries. Even after all that, an athlete is not guaranteed he or she will ever be able to play sports again. The anterior cruciate ligament is the reason that the knee only has one pattern of movement.
A 16-year-old, female high school soccer player, Lindsey Robinson, tore her anterior cruciate ligament (ACL) during a soccer game. Interestingly, she was not the only one in her team who injured her ACL, but several of her teammates have torn the same ligament as well during the soccer season. Lephart (2002) found that women involved in physical activity are more susceptible to acquiring the ACL injuries than men who are involved in the same physical activity (as cited in Ogden, 2002). According to “ACL Injury Prevention” (2004), the numbers of female ACL ruptures have increased for the past ten years. Over 1.4 million women have suffered from the ACL rupture, which is twice the rate of the previous decade.
Sports Medicine is a medical field that specializes with physical fitness, treatment and prevention of injuries related to sports and exercise. It was introduced around the early Greek and Roman era when the first modern Olympic Games took place. The Greek felt they could do something to help heal and prevent injuries that the athletes were receiving. Now in sports medicine, certain injuries can only be assessed and treated by specific physicians. These physicians can include physical therapists, athletic trainers, and strength and conditioning coaches. Although sports physicians are most commonly seen by athletes after they are hurt so they can be treated, there are some physicians that are seen before an injury occurs so that they can learn how to prevent injuries.
Injuries to the Anterior Cruciate Ligament (ACL) are one of the most frequent and devastating knee injuries that occur during sporting activities, accounting for one fifth of all sport related knee injuries ¹ ². Injury estimates have been reported in current literature to be between 1.5% - 1.7% per year within a healthy athletic population ³ ⁴. However, incidence rates for ACL injury prove difficult to access as not all individuals with ACL injuries seek medical attention ⁵. Current trends show a direct correlation between the rising incidence of ACL injury and increased sporting participation ⁶. In spite of increasing incidence rates, ACL injuries remain fairly uncommonly in relation to the amount of individuals participating in sporting activities ⁷ ⁸. Nevertheless, they still prove to be a frequent source of disability for those individuals affected ⁷ ⁸. Individuals affected with ACL injury may suffer from a number of adverse effects including dynamic knee instability, altered movement patterns, reduced functional performance and debilitating pain ⁷⁻¹⁰.
Amanda was in her sophomore year of soccer season when she heard the pop of her knee that cut her season short. The next thing she knew she was at the doctor’s who told her she had an ACL tear, and wasn’t sure if she could play again. From there it was boiled down to two options. One to re-strengthen her knee through rehabilitation, physical therapy and bracing, or to undergo an ACL reconstruction surgery. Although it is costly and some may consider it frivolous, those who have encountered ACL tears should receive the reconstruction surgery instead of attending rehabilitation for the damage to their knee, because it dramatically lessens the chances of meniscal injuries and osteoarthritis occurring later and allows the patient to return back to their sport or physical activity with better knee mobility and less pain in a timely manner.
The word patella comes from the great latin language meaning shallow pan or shallow dish. The description of that word could not be more correct, it was meant in reference to balance of food but in anatomy’s case a balance of the body. The patella is a small bone located in front of the knee joint where the thigh bone (femur) and shinbone (tibia) meet. It protects the knee and connects the muscles in the front of the thigh to the tibia. The patella is one of two sesamoid bones found in the body, roughly triangular shaped in size. It’s thick consistency allows for the articulation of the femur, which in turn allows for body support and balance. The patella has multiple body functions with the primary being knee extension. The patella is essential for basic body functions including locomotion;
The majority of ACL injuries suffered during athletic participation are of the noncontact variety. Three main noncontact mechanisms have been identified planting and cutting, straight-knee landing and one-step stop landing with the knee hyperextended. Pivoting and sudden deceleration are also common mechanisms of noncontact ACL injury. Basketball, soccer, and volleyball consistently produce some of the highest ACL injury rates across various age groups. Other activities with a high rate of injury are gymnastics, martial arts, and running. In most sports, injuries occur more often in games than in practice. Many injuries have occurred during the first 30 minutes of play. One-reason physicians are seeing more ACL injuries in female patients that more women play sports, and they play more intensely. But as they continued to do more studies, they are finding that women's higher rate of ACL is probably due ...
ACL injury is quite prevalent in the United States. About every 1 in 3,000 people suffer from an ACL injury in their lifetime, and approximately 95,000 new incidences of ACL injury occur each year. The largest amount of these injuries occurs during sports which involve twisting, cutting, jumping and deceleration. The mechanisms that can cause an ACL injury are excessive valgus (outside of knee) stress, forced hyperextension, or forced external rotation of the femur on the a fixed tibia (Evans, 2001). Many associate the tearing of the ACL with a large impact or collision, however 80% of all ACL injuries are non-contact injuries. This statistic shows that ACL injuries are mostly caused by the individual themselves as opposed to an opponent or other person. The exact mechanism of noncontact ACL tears consists of poor knee positioning (e.g. landing with an extended knee) and a strong, unopposed quad contraction (Murray, 2013).
In order to understand how the menisci can be injured, you must understand the basic anatomy of the menisci and why they are important. The menisci are two oval (semilunar) fibrocartilages that deepen the articular facets of the tibia and cushion any stresses placed on the knee joint. They enhance the total stability of the knee, assist in the control of normal knee motion, and provide shock absorption against compression forces between the tibia and the femur (Booher, 2000). Articular cartilage covers the ends of the bones that make up the joint. The articular cartilage surface is a tough, very slick material that allows the surfaces to slide against one another without damage to either surface. This ability of the meniscus to spread out the force on the joint surfaces as we walk is important because it protects the articular cartilage from excessive forces occurring in any one area on the joint surface, leading to degeneration over time (Sutton, 1999).
