Jong Ra et al.’s (2014) study measured the ceiling effects of the Lysholm score and the IKDC subjective score when utilized for evaluating functional outcomes post-ACL reconstruction and compared their concurrent validity by assessing the correlation of each score with a one-leg hop test. This was a retrospective study, consisting of 134 participants who underwent an ACL reconstruction between May 2007 and April 2011. The authors of this study set up the inclusion criteria as an ACL rupture with or without a meniscus tear and participation in the 6 and 12-month evaluation. The study sample consisted of 134 participants, including 111 males and 23 females with an average age of 27.2 years who underwent ACL reconstruction with a single-bundle hamstring autograft. A subgroup evaluation was done for subjects who were not athletically active but only participated in recreational sports and had a pre-injury Tegner score of 6 or less. The recreational sports subgroup consisted of 100 subjects with an average age of 28.6 years and an average Tegner score of 5.1. …show more content…
The participants then completed the functional evaluation by completing three one-leg hop tests on each limb. The longest distance was recorded and calculated as the percentage of the performance of the ACL reconstructed leg over the uninvolved leg, the scores were calculated as the limb symmetric index (LSI). The authors of this study defined the ceiling effect as the percent of participants who received the maximum score of 100 points. The Spearman correlation coefficient was used to examine the correlation between both scales and the limb symmetric index and was interpreted as r > 0.5 which indicated a strong association. The Kolmogorov-Smirnov test was then used to examine the distribution
Breaking News! Breaking News! During the second preseason game Green Bay Packers WR Jordy Nelson tore his anterior cruciate ligament ACL. While he was actively running his routes during the game the ball was thrown his way as he planted his foot - the pop was heard like a gunshot as his knee pulled one way and the rest of his leg the other. We got more Packers injuries as we now hear that Sam Shields Packers CB has a bad concussion and is likely out for the season. Sam was tackling a player and instead of hitting the ground normally he hit his head on the ground and that caused his brain to shake inside his skull.
It has been shown, patients that have experienced an ACL tear will have clear radiographic signs of osteoarthritis.1 These signs appear in 10-20 years after the incident whether they had reconstruction surgery or opted out of surgery.1 In the article, Meniscus treatment and age associated with narrower radiographic joint space width 2-3 years after ACL reconstruction: data from the MOON onsite cohort, the authors goal was to find out whether radiographs of the metatarsophalangeal view would notice differences in the width of the joint space between an ACL reconstructed knee and the contralateral control knee within 2-3 years.1 Secondly, they wanted to indicate risk factors for early signs of post-traumatic osteoarthritis through an analysis
The ACL (anterior cruciate ligament) is one of four ligaments to connect the thigh bone to the shin bone. The ACL stabilize the knee, controls excessive movement, and limits joint mobility. The ACL is primarily for the forward motion when walking, running, and jumping. Without the ACL the thighbone would constantly dislocate from the shin bone.
Thus obtaining on proposed rehabilitation program in accordance with the scientific foundations in order to achieve the desired benefit which represents in enhancing the functional efficiency of athletes after ACL surgery for return to their preinjury state and participate in their sports activities.
Studies have also shown that women in particular, unfortunately have a disadvantage in life when compared to male counterparts, and that is one pertaining to their higher risk for ACL injury. Due to a neuromuscular imbalance that is concomitant with overactive quadriceps strength compared to hamstring strength, females tend to place more stress on the ACL. Accordingly, this increases the pressure on the ACL leading to a higher prevalence of injury that will arise more on the female spectrum than that of the male (Myer et al., 2009). Furthermore, this is important to be aware of for female athletes and for the Physical Therapists who treat them in efforts to provide educational information regarding the relationship of stronger hamstrings correlating to a lesser chance of ACL injury. Personally, I have worked with athletic females in the past as a personal trainer and while I was not strengthening hamstrings with the direct objective to prevent an ACL injury, I was cognizant of the notion that a balanced quadriceps and hamstring ratio was necessary to avoid lower extremity injuries as a
The purpose of ACL reconstruction is to restore function by repairing normal movements, replicate knee anatomy, and to protect the knee for a long duration. More specifically, the dimensions, orientation, and insertion sites of the ACL must be restored. To ensure this, future consideration for improvement of ACL reconstruction surgery is vital.
In the final analysis, ACL tears are more commonly found in females because of the anatomical structure of women, improper body mechanics, and the differences in female’s circulating hormones. The human female structure has many differences to the male structure, such as muscle stiffness, stronger quadriceps than hamstrings, a wider pelvis bone, and smaller intercondylar notches. These differences in male and female structure can lead to why ACL tears are more frequent in females. Another reason as to why females are more prone to knee ligament tears is because of of the improper body mechanics performed by women. During sports, contact or noncontact studies show that women perform cutting movements that are more erect rather than a crouched
If you’re an athlete then you should know what an “ACL tear” is. ACL means “Anterior Cruciate Ligament.” Believe it or not, those tears often happen to pre-teens. ACL tears can be really bad, but it depends on how bad you tear it.
With an ever increasing number of people becoming involved with athletic activities, there is an increasing number of injuries occurring which can be devastating for the individual. Most of the injuries that affect athletes occur in one of four structures in the human body: bones, muscles, tendons, or ligaments. Because ligaments attach bone to bone and play a major part in providing stability for joints, the major stabilizing ligament in the knee, the anterior cruciate ligament (ACL), assists in performing everyday actions of the human body including sitting, standing, walking, running, dancing, and participating in other sports. The injury that specifically affects this ligament is very serious and always
Being an athlete and playing sports is fun, until you tear your ACL. Tearing your ACL is one of the most painful injuries for athletes. ACL injuries normally occur in non-contact activities like soccer, basketball, volleyball, skiing, and gymnastics. Not only do they occur in non-contact activities, but they also occur when you suffer a blow to the knee. Common symptoms of ACL injuries include a popping sensation, immediate pain, swelling, limping, stiffness, and feeling of the knee giving away.
The second is to validate the consequences of ACL reconstruction on the body. There is a current opinion that ACL surgery will surely repair an ACL rupture, when in fact, the proof is quite the adverse65. The surgical process from ACL reconstruction has many variable and their success power to very dependent in the patient. Even after the successful surgery the possibilities from the second ACL tear in an athlete inside 24 months from coming back to sport get up to five times that compare healthy athlete65. Finally if the athletes suffer from a positive surgery do not to hold a second ACL injury she or he still involve high risk from developing degenerative osteoarthritis in the knee
This essay deals with the current treatments, rehabilitation procedures and onsets following anterior cruciate ligament (ACL) injuries. Within this essay, there will be information including the causes, characteristics, and symptoms of ACL injuries. Throughout the United States, there are estimated to be 200,000 ACL injuries per year with 100,000 of those injuries being treated through ACL reconstruction (Evans, Shaginaw, & Bartolozz, 2014). With a satisfactory ACL reconstruction outcome between 75%-97%. From the 10%-15% failure rate of ACL reconstruction, the primary fault is due to technical mistakes at 70% (Samitier, Marcano, Alentorn-Geli, Cugot, Former, & Moser,
The anterior cruciate ligament is a stabilizing force within the knee joint. The ACL prevents hyperextension as well as limiting excessive tibial rotation and valgus/varus stresses of the knee joint. Athletes are expected to perform maneuvers that put excessive force on their knees. An ACL tear is a common injury among athletes resulting in the need for surgical intervention. After surgery and physical therapy, the goal usually included to return to sports at their prior level of competition while trying to prevent reinjury. What criteria do clinicians use to determine when the athlete is ready? Several studies were reviewed to answer this question. The results included several variables that could predispose an athlete to reinjury, several
The Functional Movement Screening was done by a certified athletic trainer for all participants. Y balance test and BESS was performed by the author. The FMS composite score ranges from 0 to 21. Y balance test composite score is calculated by summing the reach distance and normalizing to limb length by dividing the sum to three times the limb length and finally multiplying into 100. BESS error scores are summed together to give the final score.
This randomized study included Twenty-six patients with an acute ACL injury or ruptures of ACL grafts. To be involved in the study patients had to have a unilateral ACL injury, be free of other ligament or meniscal damage that would requiring surgical repair, and pass an examination designed to identify patients who would had the potential to return to a high-level physical activity with nonoperative treatments. Patients also have regular participation in some level I activities (eg, soccer, footbof all, basketball) or some level II activities (eg, racquet sports, skiing, construction work). Patients were randomly assigned to either a group that received the standard
