INTRODUCTION Patellofemoral pain affects physically active and sedentary individuals, accounting for 11–17% of knee pain presentations to general practice 2 and 25– 40% of all knee problems seen in a sports injury clinic. 4 Patellofemoral pain is characterised by anterior knee pain associated with act...

BACKGROUND Patellofemoral pain is a very common musculoskeletal condition. In the last years, evidence regarding this disease increased exponentially. Although widely investigated, this problem still frustrates patients and clinicians for having an unfavorable prognosis. Some gaps still exist in the understanding and managing of patellofemoral pain. Numerous cross-sectional association studies ...

Background & Aims: The purpose of this study was to determine the immediate effect of patella support brace on co-contraction and electromyographic activity of selected lower limb muscles in females with patellofemoral pain syndrome during stance phase of gait. Methods: EMG activity of vastus lateralis, vastus medialis, rectus femoris, gastrocnemius, biceps femoris, semitendinosus, gluteus medi...

Patellofemoral pain is a common knee disorder with a multi-factorial etiology related to abnormal patellar tracking. Our hypothesis was that the pattern of three-dimensional rotation and translation of the patella induced by selective activation of individual quadriceps components would differ between subjects with patellofemoral pain and healthy subjects. Nine female subjects with patellofemor...

BACKGROUND Unrelieved postoperative pain may impair rehabilitation, delay recovery, and result in poor outcomes. Preventive multimodal analgesic techniques may improve long-term outcome after surgery. METHODS We randomized 200 consecutive patients to receive acetaminophen 1000 mg and either celecoxib 400 mg or placebo 1-2 h before anterior cruciate ligament surgery. All patients received intr...

Patellofemoral pain syndrome (PFPS) is a common ailment of the knee. Both open and closed kinetic chain exercises are effective in strengthening of the quadriceps muscle. It has been suggested that these exercises are used jointly in the management of PFPS, but no study to date has evaluated the effect of combined open and closed kinetic chain exercises on PFPS. The present randomized controlle...

BACKGROUND foot orthoses have been described as a possible intervention for individuals with patellofemoral joint pain. No study has attempted to quantify the perceived comfort and support of foot orthoses when used as an intervention for patellofemoral joint pain. METHODS a randomized case-control trial with crossover between contoured and flat orthoses was conducted on ten individuals with ...

Patellofemoral pain syndrome (PFPS) is a very common disorder of the knee. Due to multiple forces influencing the patellofemoral joint, clinical management of this ailment is particularly intricate. Patellofemoral pain syndrome has a multifactorial nature and multiple parameters have been proposed as potential risk factors, classified as intrinsic or extrinsic. Some of the intrinsic risk factor...
