Introduction
Chronic knee pain is a common symptom in pathologies and conditions such as tibiofemoral and patellofemoral osteoarthritis (OA), anterior cruciate ligament (ACL) tears, and patellofemoral pain (PFP). These injuries are treated by physical therapists today more than ever before.
In the United States, OA is the most common joint-related disorder (Zhang and Jordan, 2010). This study also reported that OA specific to the knee occurred in 13% of women and 10% of males over the age of 60 years old in 2010. The prevalence of OA is likely to increase in the future with the aging of the American population (Zhang and Jordan, 2010). This increase in OA prevalence is likely to have a major economic impact as well; a 2011 study utilizing

Previous studies have shown that the PFP tends to be exacerbated during activities that require high knee extensor forces of the quadriceps muscle group, such as ascending and descending stairs, running, or squatting (Brechter & Powers, 2002). People with both OA in the knee and PFP have been shown to have lower knee extensor moments during level walking, and it has been theorized that this pattern is in an attempt to decrease the loading on the patellofemoral joint and therefore decrease pain (Kaufman, Hughes, Morrey, Morrey, & An, 2001; Brechter & Powers, 2002). People with previous ACL reconstructions tend to display this same pattern of decreased knee extensor moment, although in such cases it could be due to factors other than pain (Ernst, Saliba, Diduch, Hurwitz, & Ball, 2000).
A study by Messier et al in 1992 observed a shorter stride length during level walking in participants with osteoarthritis compared to a healthy population. On the contrary, Hewett, Myer, & Ford (2006) observed that a larger stride length with the knee at or near full extension was the cause of the majority of non-contact ACL injuries. Altering stride length may be a way of compensating for pain in existing conditions such as OA or cause acute trauma leading to injuries such as ACL tears. Further investigation of stride length was included in this study to observe if
1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1, 22) = 9.619, p = 0.005. Discuss each aspect of these results.
In this study, a randomized and concealed method supported by a computer was conducted prospectively for patients who showed signs of radiographic knee OA. In addition, without knowing further about the clinical status of participants, knee radiographs were assessed in the study of baseline and follow ups by an experienced surgeon. The baseline characteristics of subjects such as age and BMI were not significantly different. Criteria included were the radiographically confirmed as knee OA (a score ≥ 1 out of 4 on the K/L scale), ability to walk to the site, understand and make signature on the written consent of information form and report the data required. However, the research did not include the participants
These boots move the forces caused by a fall to the knee rather than the ankle or lower leg. The ACL injury usually occurs when the knee is forcefully twisted, or hyper-extended. Many patients recall hearing a loud pop when the ligament tears, and feel the knee give way. This injury has received a great deal of attention from orthopedic surgeons over the past 15 years and very successful operations to reconstruct the torn anterior cruciate ligament have been performed.
Osteoarthritis, or degenerative joint disease, is a form of arthritis characterized by the breakdown of cartilage within joints. Cartilage serves to provide cushion at the ends of bones, and when the cushion is not sufficient, as in osteoarthritis, the bones rub together. As a result, osteoarthritis sufferers are constantly plagued by stiff, swollen, and inflamed joints (http://www.arthritis.org/answers/diseasecenter/oa.asp). It is a relatively common condition, with an estimated 20 million American sufferers, most of whom are elderly (http://webmd.lycos.com/content/article/1668.50297). Traditional treatments include Tylenol, aspirin, or other non-steroidal anti-inflammatory drugs
Subjects: 50 participants with PFPS between 18 and 45 years of age, with patellofemoral pain Syndrome for more than 1 month, pain level ≥ 3 on a Numeric Pain Rating Scale (NPRS), pain during at least 2 activities, such as squatting, ascending, descending stairs, and/or running, Unilateral PFPS, and participants are not on pain medication.
The foremost cruciate ligament (ACL) gives security and quality to the knee by averting front interpretation of the tibia under the femur and inordinate pivot through the knee it essentially keeps the knee from turning the distance around. The ACL is harmed amid running ball games, skiing, or bouncing game, so this is discovered more in more youthful grown-ups. It is frequently joined by damage to the average security ligament (MCL) and the average meniscus and that is known as a blown knee when you tear every one of the three. These mix wounds are connected with a higher commonness of radiographic osteoarthritis at 10-15 years, yet these patients demonstrate no distinctions in capacity contrasted with those with an detached ACL damage. The patient with an ACL break usually report a sudden sharp torment and precariousness amid rotating or a fast alter of course, or on effect, for example, a fall or handle. They additionally have heard or felt a thump as the joint separates or a snap of the muscle. On the off chance that there is intra articular muscle harm, the patient will report swelling (because of haemarthrosis). They might likewise give lost extent or development because of the torment and a sentiment unsteadiness on the weight bearing knee. The GP will watch, inspect the knee, screen and upgrade on swelling and emission. The foremost drawer tests the adaptability of the front ligament, Lachman test and the turn shift test are most normally used to test the strength of the knee joint. The level of crack or vicinity of different wounds can be affirmed by X-ray. Different ways while inspecting the patient in the event that they give atypically or abnormal amounts of torment are bone wound, microfractures, post-corner harm and tibial level breaks. All patients with suspected ACL wounds ought to see a physiotherapist inside of the initial two
There have been many studies done to explain the higher rate of ACL injury in female athletes. The most convincing findings relate to knee kinematics and neuromuscular control. In a study of 20 subjects (10 male and 10 female) forces from jump tasks were recorded using 3-D videography and force plates. One conclusion from the study was that force on the ACL was greatest during the landing phase of a jump tasks. Females frequently showed more leg extension and valgus movements during the landing phase, which also puts more stress on the ACL (Chappel et all, 2002). A similar study found that internal rotation combined with valgus movement creates
Common lower extremity injuries for runners are iliotibial band syndrome, patellofemoral syndrome, patellar tendonitis, and plantar fasciitis. Iliotibial band syndrome occurs in runners who perform long distance training because of excessively bending and extending their knee (Grau, Maiwald, Krauss, Axmann, & Horstmann 2008). This will cause the distal iliotibial band to rub or brush against the lateral femoral condyle which will cause inflammation and swelling of the iliotibial band (Grau, et al., 2008). Patellofemoral pain syndrome or “runner’s knee” can cause excruciating anterior knee pain because of weak hip abductors, quadriceps, and external rotators (Petersen, Ellermann, Gösele-koppenburg, Best, Rembitzki, Brüggemann & Liebau, 2014). This will wear down, disrupt and ultimately damage the cartilage under the knee cap. Patellofemoral pain syndrome will cause imbalance and instability of the patella, hamstring
DOI: 3/14/2014. Patient is a 57-year-old female lead operator who sustained a work-related injury when she twisted her right knee as she stepped down off a chase cart. As per OMNI, the patient was diagnosed with chronic right knee pain status post anterior cruciate ligament repair, and significant degenerative joint disease of the knee. She is s status post right knee anterior cruciate ligament (ACL) reconstruction on 07/15/14.
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
Osteoarthritis is the most common joint disorder, and more than half of all Americans who are older than 65 have been diagnosed with osteoarthritis. However, recent US data has revealed knee osteoarthritis does not discriminate age, and there is growing evidence that osteoarthritis affects individuals at a young age. The annual cost of osteoarthritis due to treatment and loss of productivity in the US is estimated to be more than 65 billion dollars.1 With no cure currently available for osteoarthritis, current treatments focus on management of symptoms. The primary goals of therapy include improved joint function, pain relief, and increased joint stability. Although the exact cause of osteoarthritis is unknown, many risk factors have been identified including increased age, female gender, obesity, and trauma.2 Within these risk factors, the etiology of osteoarthritis has been divided into anatomy, body mass, and gender.
According to Goodman and Fuller (2009) Osteoarthritis is divided into 2 classifications: Primary and secondary. Primary OA is a disorder of unknown cause which in the cascade of joint degeneration it is believed to be a related defect in the articular cartilage. Secondary OA has a known cause, which may be trauma, infection, hemarthrosis, osteonecrosis, or some condition Primary Osteoarthritis (OA) is the most common joint disorder in the world and often affects the knee and hip joints (Rubak, Svendsen, Soballe, & Frost, 2013). For patients with primary hip OA, pain and disability are the most important indications for total hip replacement (THR) (Rubake et al., 2013, p.486) Primary symptoms of OA include joint pain, stiffness, and limitation of movement. Disease progression is usually slow but can
Anterior knee pain syndrome is clinical condition in adolescents and young adults characterized by diffuse pain in anterior aspect of the knee extending down the front of the leg. The most common cause of this pain is Chondromalacia patella. (2)
