Summary: Radiographic Signs Of Osteoarthritis

Osteoarthritis (OA) is the most common joint disorder. It occurs when cartilage begins to break down or be worn away and the bone rubs together. As a result bony spurs and inflammation of the joint(s) occurs. Surrounding ligaments and muscles may also weaken or stiffen. Major risk factors are: genetics, excess weight, joint injuries, jobs that involve more than an hour of joint stressing activities like kneeling, and sports that involve direct impact on the joints, twisting, or throwing. Bleeding disorders, disorders that blood supply near joints, and other types of arthritis can cause osteoarthritis. Symptoms typically begin while one is middle aged and almost everyone shows some symptoms of OA by age 70. This is important to note because OA is seemingly inevitable for everybody. OA is not curable and typically gets worse with time, but the symptoms can be managed. Strength in weight bearing joints, the hip, the knee, and the ankle, is particularly important for prevention. Also important are not overusing joints and maintaining a normal body weight.

Mean follow-up was 117 months. 86% are male. Average age of 26 years at surgery. 35 patients had partial meniscectomy (53% internal, 31% external, 16% bimeniscal). A significant improvement (p<0.001) between pre and postoperative parameters was demonstrated (pre-operative mean IKDC score 47 points; post-operative 94 points). 92% perform moderate demand activities, of which 40% returned to pre-injury activity levels without complaints. An increase in the time between rupture of the ACL and surgery was not associated with higher rates of meniscal lesions, osteoarthritis or lower IKDC scores. There was a correlation between clinical results and associated meniscal or chondral lesions. Clinically 6% had symptoms/signs of anterior instability (Lachman 2 A). Radiologically 25% had an anterior displacement of the tibia with an average distance of 3.9 mm [3.3-7.2]. 10% shown femoral tunnel enlargement (with a average of 1.8 mm) and 60% present with subchondral sclerosis in tibial plates. All patients with symptoms suggesting anterior instability shown anterior displacement of the tibia and sclerosis areas, yet only one has femoral tunnel

The magnitude of the problem is clear, as a high incidence of ACL injury, particularly in young athletes. Recent evidence suggests that more than half of athletes who undergo ACL surgery are unable to return to their preinjury level of function after ACLR surgery. Return to sports activities remains a very difficult topic. Thus the research regarding the rehabilitation process of athlete after

The purpose of this article is to compare the laxity and stiffness of the knee joint in male and female cadavers. Three different directions will be evaluated, anterior-posterior, internal-external, and varus-valgus. Females are at a two to eight times greater risk of an ACL injury than a male. This is due to the laxity in the joints. Females also have limited proprioception in the knee joint, which may attribute to some injuries. This study used a technique using cadaver knees to complete this study.

The anterior cruciate ligament (ACL) has limited range of motion, which leads to it being the most frequently injured ligament singularly (Ireland, 1999). This study was conducted to present the epidemiology on ACL injuries in female athletes (Ireland, 1999). Epidemiology is the part of science that focuses on the causes, effects, and patterns of disease and health conditions that occur in specific populations. The epidemiology in this article focuses on female athletes that have had a noncontact ACL injury playing either basketball or soccer (Ireland, 1999).

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

INCREASE IN TEARS Anterior cruciate ligament injuries are receiving a great deal of notice because of the incidence of injury that occurs not only in the athletic population but also in those individuals who are recreationally active (Russell, 2006). Each year in the United States there are approximately 250,000 ACL injuries. This is approximately 1 in 3,000 in the general population (Boden, 2000). Of these injuries, about 175,000 require reconstructive surgery. These surgeries had an estimated cost of over two billion dollars annually in the United States (Yu, 2007). These statistics alone make it obvious that this injury occurs very often. The ACL is one of the most commonly disrupted ligaments in the knee. While the prevalence of the injury has increased, so has the number of athletes in the world since ACL injury research first began. Women are now allowed to participate in sports and new sports are being participated in

In sport an ACL injury is the most frequently ruptured ligament of the knee (Johnson, 1983), it is described by Flynn 2005 as a serious, common and costly injury (Flynn, 2005). In many cases an ACL injury is the result of noncontact and studies done by Barrett et al 1972 and Beckett et al 1992 support this as they reported that 78% and 71% of ACL injured patients described noncontact mechanisms of injury such as landing with too much knee extension or change in direction (pivoting) (Barrett et al 1972 and Beckett et al 1992) and also can happen due to contact such dominant kicking leg, fall on the knee or even a forceful blow to the knee. Bjordal et al 1997, in their findings showed that 58% and 42% of ACL injuries were

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.

Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It occurs when the protective cartilage on the ends of your bones wears down over time. Most people don't know they have it because the aches, tenderness, stiffness dont feel like arthritis until x-rays prove it. Just like regular arthritis, it affects the skeletal system. This is because it causes the bones to wear and then become stiff.Primary osteoarthritis, osteoarthritis not resulting from injury or disease, is mostly a result of natural aging of the joint. With aging, the water content of the cartilage increases, and the protein makeup of cartilage degenerates. Eventually, cartilage begins to degenerate by flaking or forming tiny crevasses.Secondary

ACL tears are the most common type of knee injuries seen in athletes. The ACL is viewed as the most important ligament in the entire knee. To elaborate, it helps provide stability throughout the entire leg. Although the majority of these injuries result from contact sports, such as football, some result from non contact sports, such as tennis, as well. This injury can result from overstretching the anterior ligament or completely tearing it (Brown University, n.d.). According to Brown University (n.d.) in a study by the National Football League, 100% of football players suffering from ACL injuries, through a five year span, required some sort of surgery. In contrary, an ACL injury recovery time can be more accurately determined in comparison to concussions. In most instances an athlete’s recovery time can vary from six to nine months. Though knee injuries have more

OA is a musculoskeletal disease that causes chronic joint pain and reduced physical functioning (Laba, brien, Fransen, & jan, 2013). Osteoarthritis (OA) is a non-inflammatory disorder of synovial joints that results in loss of hyaline cartilage and remodeling of surrounding bone. OA is the single most common joint disease, with an estimated prevalence of 60% in men and 70% in women later in life after the age of 65 years, affecting an estimated 40 million people in the United States (Goodman & Fuller, 2009). Women are more commonly affected after the age of 55, almost everyone has some symptoms by the age of 70 (Tan, Zahara, Colburn & Hawkins, 2013, p.78). Osteoarthritis can be described radiological, clinical, or subjective.

ACL injuries used to be seen as career ending injuries 50 years ago, however, throughout the years with the advancement in technology aiding treatment and rehabilitation procedures. Yet they are still sever and take months to recover. This is because of the precise location of the ligament within the knee joint. Resulting in no blood clot formation within the joint as a consequence scar tissue will not form and the tissue will just be filled with uncontrolled blood leading to swelling an pain within the joint (ACL reconstruction Oxford university hospital, 2017) which is why it takes between 9 to 12 months for recovery. With an ACL injury, other injuries often follow, namely MCL injuries and meniscal lesions which in time would likely lead to the patient contracting osteoarthritis due to it being a degenerative disorder consequently resulting from the meniscal and

Most report of successful non-operative injury come from case series. One prospective cohort study of 100 consecutive patient with non-operative treatment ACL injuries found that 15 year follow up 68% had a symptomatic knee (Neuman et al 2008)58.
