Patellofemoral Pain SyndromePatellofemoral Osteoarthritis1 moreThe purpose of this study is to translate and culturally adapt the subscale of the Knee Injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF) into Turkish, and to determine the measurement properties of the Turkish version.
Pain Mechanisms in Young Adolescent Females With Longstanding Patellofemoral Pain
Patellofemoral Pain SyndromePainPatellofemoral pain (PFP) is a highly prevalent musculoskeletal condition in adult females, which is associated with decreased quality of life and physical activity levels. PFP is highly persistent, with up to 50% of adolescents reporting persistent pain at both one and two year follow-ups. Previous research has demonstrated altered pain sensitivity in in older individuals with chronic pain, however, less is known about this in conditions such as PFP, which is common in younger populations. Additionally it is unknown if these characteristics return to similar values as healthy controls, when symptoms resolve. The aim of this study will be to compare pain sensitivity in individuals with PFP, compared to those with a previous history of PFP who currently are pain-free, and a control group with no history of knee pain.
5 Year Follow-up of Adolescents With Knee Pain
Patellofemoral Pain SyndromeKnee PainThe prevalence of adolescent knee pain is 33%, and patellofemoral pain (PFP) is the most common diagnosis with a nontraumatic onset. The 5-year prognosis of adolescent PFP compared with other types of knee pain is unknown. In 2011, a cohort of 2200 adolescents aged 15 to 19 years answered an online questionnaire on musculoskeletal pain. Of these, 504 reported knee pain, and 153 of these were clinically diagnosed with PFP. Now, after 5 years, the 504 adolescents, as well as 252 randomly selected adolescents who did not report knee pain in 2011, will be contacted again to gain insights into their prognosis.
Step Rate Retraining to Reduce Injury and Disability (STRIDe)
Overuse InjuryLower Extremity Problem4 moreThis study will be the first project to evaluate the effectiveness of wearable technology (Garmin Forerunner35) while performing gait retraining in field on military members. The watch will provide real time feedback to the runner on their step rate while performing running sessions outside of the lab. This allows the runner to modify their step rate to meet a recommended step rate provided by the study team member. Aim 1: To demonstrate the utility of wearable sensors to modify running step rate through real time biofeedback. Aim 2: To determine whether altering step rate using real time biofeedback reduces lower extremity musculoskeletal injury reoccurrence within 1 year post training.
Efficiency of Patellar Taping in Treatment of Patellofemoral Pain Syndrome
Patellofemoral Pain SyndromePatellar 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.
Prevention of Injuries by an Exercise Program - a RCT
Patellofemoral Pain SyndromeExertional Lower Leg PainOveruse injuries are a major concern for physical active individuals. Study hypothesis is that an exercise programme based on known intrinsic risk factors can prevent overuse injuries in soldiers undergoing basic military training.
Joint Position Sense in Individuals With Anterior Knee Pain
Anterior Knee Pain SyndromeProprioceptive DisordersIntroduction Anterior knee pain (AKP) commonly affects physically active as well as sedentary individuals and the aetiology remains unknown. Altered joint position sense (JPS) impacts accurate motor action and knee joint stability. It is unclear whether people with AKP have altered JPS. The aim of this study was to investigate the JPS of individuals with AKP. Methods A descriptive cross-sectional design was used to measure JPS in twenty-five participants with unilateral or bilateral AKP. The Vicon 3D motion analysis system was used to assess JPS by means of active joint position sense testing during single leg squat and active knee extension in sitting. Target angles were self-determined based on each participant's capabilities. The absolute error (AE) was used as the main outcome measure. Impaired JPS was classified as an AE equal to or greater than five degrees.
Patellofemoral Pain After Unicondylar Knee Arthroplasty
Mobile-bearing Unicondylar Knee ArthroplastyUnicondylar knee arthroplasty (UKA) is a proven procedure in patients suffering from unicompartmental knee osteoarthritis. Two different types of UKA design are available - both with different pros and cons. The so-called 'mobile-bearing UKA' requires the removal of an additional amount of cartilage and bone close to the implantat. It is unclear whether this is of clinical relevance. We speculate that the amount of cartilage/bone removal is related to the clinical outcome of the UKA-surgery. In patients receiving a mobile-bearing UKA that amount of cartilage/bone removal is measured during the surgery. The clinical success of the procedure will be determined with certain knee questionnaires (Kujala & KOOS)preoperatively, 3 months postoperatively, 6 months postoperatively and 1 year postoperatively. Additionally, the so-called bone-remodelling around that area of resected cartilage and bone will be measured (SPECT-CT) postoperatively. The three variables (removed amount of cartilage/bone; clinical success with regard to the questionnaires; bone remodelling) are then analyzed with statistical methods to find out potential assoziations among them.
Bone Metabolic Activity in the Patellofemoral Joint in Patients With Unilateral PFP
Patellofemoral Pain SyndromeAnterior Knee Pain SyndromeThis study aims to examine whether individuals with unilateral patellofemoral pain (PFP) have increased subchondral bone remodelling and thus increased 18F Sodium Fluoride (18F-NaF) uptake in the painful knee compared to the opposite knee measured by simultaneous positron emission tomography and computed tomography (PET/CT) and to examine whether the increased uptake is associated with pain intensity, with patient-reported function and with pain localization. Furthermore we aim to investigate the effect of an acute patellofemoral loading bout on the bone remodelling.
Trial of Self-managed Approaches for Patellofemoral Pain Syndrome in Active Duty
Patellofemoral Pain SyndromeThe overall objective of this project is to compare the three home-managed treatment regimens for PFPS: neuromuscular electrical stimulation (NMES), transcutaneous electrical nerve stimulation (TENS), and NMES combined with TENS to a standard home exercise program (HEP). Each of the three treatment arms will be supplemented by HEP and compared to a group receiving standard HEP alone. The central hypothesis is that the combination of NMES with TENS will show significantly greater improvements in muscle strength, mobility, pain, daily activity and quality of life (QOL) than HEP alone. The investigators are examining: 1) whether the three treatment regimens are significantly more efficacious than standard HEP alone in improving lower extremity muscle strength, physical activity, mobility, pain, and quality of life; 2) lower extremity muscle strength, physical activity, mobility, pain, and quality of life differ significantly across the 4 time periods; 3) is there an interaction between treatment and time in relation to lower extremity muscle strength, physical activity, mobility, pain, and quality of life.
