BACKGROUND Patellar stabilizing braces are used to alleviate pain and prevent subluxation/dislocation by having biomechanical effects in terms of improved patellar tracking. The purpose of this study is to analyze the effects of the dynamic patellar realignment brace, Patella Pro (Otto Bock GmbH, Duderstadt, Germany), on disease determinants in subjects with patellofemoral instability using upr...

CASE REPORT We present a case of a 57 year old female whose patella became locked above a femoral osteophyte. She attended A & E at the Royal Victoria Hospital, Belfast. She had been pushing a chair forward under a table with her left knee when she felt a 'pop' inside it followed by severe pain. She was unable to bend or weightbear on the knee. Her left knee was previously asymptomatic with no ...

Levels of lead in bone serve as a dosimeter for cumulative exposure to lead; moreover, lead in bone may serve as an internal source of circulating lead many years after environmental exposure has ceased. The authors measured lead in blood and used a K-x-ray fluorescence instrument to measure lead in the tibia (cortical) and patella (trabecular) bones in a cross-sectional survey of 719 middle-ag...

Abstract A 75-year-old man presented to our emergency department with a bleeding wound 19 days following primary hinged left total knee replacement, performed elsewhere, for lateral tibiofemoral osteoarthritis. Examination revealed held in fixed flexion of 30°, partial dehiscence the wound, implant exposure and visible patella. Radiographs an abnormally raised joint line vertical appearance pat...

We report a case of 29 yr old male patient with right sided transverse patella fracture in grade Iamb open wound as per Gustillo Anderson classification due to road traffic accident. As it was an we wanted early intervention for better recovery patients ROM around knee without any morbidity. utilized novel technique which reinforced the patellar tendons by tying Krakow and distal pole tied supe...

BACKGROUND According to the literature, closing and opening wedge high tibial valgus osteotomies can raise or lower the patella, and diffèrent methods of patella height measurement show similarly conflicting results. Clarification of this was thought to be important because there is much literature describing morbidity secondary to patella alta or patella infera (baja). Effects on tibial slope ...

Abstract The McKibben pneumatic actuator (MPA) is a soft used for performing various practical functions in robots. Particularly, many dynamic robots have been realized using MPAs. However, there trade-off between torque generated by MPA and the range of motion joint. In this study, we focus on jumping leg-type robot use an elliptical pulley whose moment arm changes depending robot’s posture. T...

Introduction: In a recent survey on 25,124 knee arthroscopies, cartilage lesions were found most frequently within the patella (36%) and the medial femoral condyle (34%). However, there is a clear topographical difference in cartilage surface and cartilage thickness between these two anatomical sites. Furthermore, when looking at biochemical and biomechanical properties, this regional variation...
