Filter by:The patellofemoral pain syndrome (PFPS) is defined as a painful complaint in the anterior aspect of the knee, although peripatellar pain and / or retropatellar are also common. In general, conservative treatment is the initial option of choice for patients with PFPS, however, the lack of a specific causal factor makes it difficult to choose the best treatment so early. This way, the purpose of this study is investigate the effects of the quadriceps femoris strengthening versus hamstring stretching in patients with pattellofemoral pain.
The purpose of this study is to determined if a lower back treatment would change the hip and knee muscle activities in people with and without anterior knee pain. The investigators hypothesized that the lower back treatment may change the hip and knee muscle activities in people with anterior knee pain but not in people without anterior knee pain.
Patellar subluxation is a common disorder that may cause patellofemoral pain syndrome. The efficiency of patellar taping in the treatment of patellofemoral pain syndrome has been reported good outcomes in most patients. However, some studies reported less effective in patients with higher body mass index, larger lateral patellofemoral angle, and smaller Q angle. The investigators hypothesized that femoral internal rotation is a negative factor to the patellar taping. The investigators enroll consecutive 100 patients with anterior knee pain and radiographic evidence of patellar subluxation. The investigators determine femoral rotation via physical examination. The visual analogue scale was evaluate to compare the result between the those with and without femoral internal rotation.
Self-reported, unspecific knee pain is highly prevalent among adolescents. A large proportion of the unspecific knee pain can be attributed to Patellofemoral Pain Syndrome (PFPS). There are a number of treatment options for PFPS. Physical therapy has been advocated as one of the cornerstones in rehabilitation of patients with PFPS. Twenty-five years ago, McConnell proposed a multimodal approach that combined several treatment options. The regimen included retraining of the vastus medialis oblique muscle through functional weight bearing activities. This exercise is combined with patellar taping, patellar mobilization, and stretching to improve patellar tracking, reduce pain, and enhance vastus medialis oblique muscle activation. Short term results (<12 months) indicates that multimodal physiotherapy is more effective than placebo treatment. While treatment for PFPS may be successful for the short-term, long-term results are less promising. A recent review covering the long term prognosis for patients diagnosed with PFPS, reported that only 1/3 of those diagnosed with PFPS and treated conservatively were pain free 12 months after diagnosis. Further ¼ stopped participating in sports because of knee pain. Predictors of long term outcome (>52weeks) indicate that a long symptom duration, higher age and greater severity at baseline are associated to poorer outcome after treatment. These prognostic factors suggest that an early initiation of treatment might lead to a better long-term prognosis. The purpose of this study is to examine the short and long-term effectiveness of multi-modal physiotherapy compared to standard wait-and-see treatment applied at a very early state of disease among adolescents. The investigators hypothesized a significantly larger proportion of completely recovered patients at three-month follow-up in the interventions group compared to the control group.
The purpose of this study is to determine if interventions applied at a distant site, lumbopelvic region (manipulation and TENS), have a similar effect as interventions applied locally at the knee (TENS) on quadriceps force output and activation as well as reports of pain during common exercises in individuals with PFPS.
Patellofemoral pain syndrome (PFPS) is the most common running injury and is believed to be associated with higher than normal knee joint loading. Footwear has been developed that may decrease these knee loads in healthy subjects, but their effects on patients with PFPS are unknown. In this study, we aim to test the effects of such footwear on patients with PFPS. We hypothesize that patients who receive the footwear intervention will show a decrease in knee joint loading, and consequently will show improvements in subjective levels of perceived knee pain over a period of six weeks compared to a control condition.
With this study two different therapeutic exercise regimens will be compared in patients with anterior knee pain (patellofemoral pain syndrome, PFPS).
Background: - Patellofemoral pain syndrome is one of the most common knee problems. It is characterized by pain in the front of the knee that is aggravated by deep knee flexion, prolonged sitting, and repetitive movement. The most widely accepted theory regarding the source of this pain is that a force imbalance around the knee puts extra stress on the area, leading to pain. - Researchers are interested in learning more about the muscle groups around the knee to better understand the causes of knee pain. Objectives: - To obtain more information on how muscles, tendons, and bones work together to cause motion in the knee, both in the normal state and after immobilizing certain muscles around the knee. Eligibility: - Healthy individuals between the ages of 18 and 55, who have no current or chronic muscle, bone, or joint problems and who have no implants or other problems that would prevent them from receiving a magnetic resonance imaging (MRI) scan. Design: - This protocol will be carried out over two visits, both of which will involve using standard MRI sequences to look at the knee at rest and in motion. - The first part will examine the knee under its natural state, with a standard MRI scan of the knee both at rest and in motion. - The second part will involve temporarily reducing the force producing capabilities of one of the extensor muscles in the knee. To do so, study doctors will inject lidocaine into the muscle, which will temporarily (for approximately 2 hours) block the force producing capacity of this muscle, and then perform the MRI scan....
The first purpose was to compare the difference between leg press exercise(LPE) and additional hip abductor and external rotator muscle strength training to leg press exercise(LPE+HAE) in muscle strength, hip kinematics during step down, pain severity and function for patients diagnosed with patellofemoral pain syndrome. The second one was to discover the relationship between the change in muscle strength performance and the difference of hip joint kinematics post treatment.
Anterior knee pain has been an enigmatic problem for orthopedic surgeons. Recent studies, as well as the clinical observation of the principle investigator have suggested that arthroscopic resection of the infrapatellar plica (IPP), a vestigial remnant from embryonic development of no known clinical or biological significance, may eliminate this pain. The mechanism whereby this pain is related to the IPP is unclear. This study will document the mechanical behavior of the IPP, its kinematics, as recorded on video among a group of subjects who are undergoing arthroscopy. Radiographic visualization of the observed behavior will be obtained by injection of contrast material, and then fluoroscopic recording of a standard series of motions. The plica will then be resected to avoid any possibility of residual symptoms related to its presence. Further fluoroscopy of the knee without plical attachment, will allow the kinematic behavior to be assessed. The procedure will then be terminated.
