Abstract Background Whether vastus medialis obliquus atrophy exists in patients with patellofemoral pain syndrome and whether the amount of differs between lateralis muscles remain unknown. Materials From June 2016 to March 2019, 61 were retrospectively included study group, an age-, sex-, body mass index-matched cohort normal knees was randomly selected as control group. All enrolled subjects ...
INTRODUCTION Acute patellar dislocation is a common injury usually associated with a significant traumatic mechanism resulting in lateral displacement. Vertical axis rotation following dislocation is a rare variant of this type of injury and can prevent closed reduction in the acute setting. CASE PRESENTATION A 32-year old gentleman presented with an irreducible patella dislocation following ...
The Blackburne and Peel method of assessing the position of the patella was applied to 185 knees with Osgood--Schlatter disease in 125 patients. The normal index of 0.80 was confirmed in 73 control knees. The average index in the knees with Osgood--Schlatter disease measured 1.01 (patella alta) boys and 0.91 in girls. The value increased to 1.06 in boys with radiological evidence of loose ossic...
The purpose of this study was to compare the knee extensor mechanics in persons with and without patella alta. Thirteen subjects with patella alta and 14 subjects with normal patellar position participated in the study. Sagittal and axial MR images of the knee were acquired at 0 degrees , 20 degrees , 40 degrees , and 60 degrees of knee flexion. Measurements of actual moment arm, patellar ligam...
PURPOSE This study compared the results of rotating-platform high-flexion (RP-F) total knee arthroplasty with low contact stress (LCS) for clinical and radiographical assessment after a short-term period. MATERIALS AND METHODS 68 total knee arthroplasties using a RP-F and LCS system were analyzed retrospectively. Thirty-five of the 68 were osteoarthritic knees and were followed-up for more th...
Objective. To investigate the effect of patella taping on normal subjects. This was undertaken through the examination of isokinetic quadriceps strength and functional performance (hop distance), in an attempt to clarify the mechanism behind patella tapings reported success in the patellofemoral pain syndrome (PFPS) patient population. The aim of the study is to examine the effect of patella ta...
background: patellar mal tracking is responsible for pain and disability in patellofemoral pain syndrome (pfps). patellar kinesio taping may have different effects on short and long term usage. the aim of this study is to compare the effect of short term and long term patellar kinesio taping in patellar position on women with patellofemoral pain syndrome using magnetic resonance imaging (mri). ...
Congenital lateral dislocation of the patella is a rare condition caused by displacement of the extensor mechanism of the knee, which occurs before or shortly after birth (Malkin 1932). The patella is small and cannot be replaced in its normal position except by operation. This type of dislocation differs from recurrent or habitual dislocation of the patella, which occurs during childhood or ad...
BACKGROUND The shape of the patella has been considered to be a predisposing factor resulting in patellar instability, but the effects of abnormal patella position during its development are unclear. The present study evaluated patellar morphological changes after patella instability and evaluated the influence of patellar instability on the patella shape. METHODS Twenty rabbits that were 2 m...
