OBJECTIVES The effect of cryotherapy on joint positioning presents conflicting debates as to whether individuals are at an increased risk of injury when returning to play or activity immediately following cryotherapy application at the knee. The aim of this study was to investigate whether a 20 min application of crushed ice at the knee immediately affects knee joint position sense during a sma...

INTRODUCTION Adrenomedullin is a potent vasodilatory and hypotensive peptide as well as an endogenous immunomodulatory factor with predominantly anti-inflammatory effects. The purpose of the present study was to evaluate the therapeutic effects of adrenomedullin in rabbits with antigen-induced arthritis, an experimental model of rheumatoid arthritis. METHODS Following the induction of arthrit...

The usefulness of forward dynamic simulations to studies of human motion is well known. Although the musculoskeletal models used in these studies are generic, the modeling of specific components, such as the knee joint, may vary. Our two objectives were (1) to investigate the effects of three commonly used knee models on forward dynamic simulation results, and (2) to study the sensitivity of si...

Background: The determinant role of different movements to strengthen the quadriceps on rate of knee joint co-contraction, hamstring to quadriceps muscle activity ratio and vastus medialis to vastus lateralis muscle activity ratio provides useful information for therapists, coaches and athletes about the role of each movement in the rehabilitation of patients with anterior cruc...

  Periarticular cyst and cystic soft tissue lesion around the knee are common. Synovial sarcoma is a rare and malignant soft tissue tumor accounting for approximately 5% of soft tissue sarcoma. A case is presented where a lesion adjacent to the joint line of the knee was diagnosed clinically and on imaging as a meniscal cyst. MRI signal was homogenous and no concomitant meniscal tears were seen...

SUM.MARY. S. Bruhn, A. Gol/hofer, and M. Gruber: Proprioception trainingfor prevention and rehabilitation of knee joint injuries. Eur. J. Sports Traumato!. reI. res. 23: 82-89, 2001. The purpose of this study was to evaluate the eJJects after 4-week proprioception training onjilnctionaI stability of the knee joint and on the interand intramuscular coordination. In order to estimate the coordina...

Objective: To assess the biomechanic effects of wearing a ateral wedge on the knee joint varus moment during gait in lders with and without knee osteoarthritis (OA). Design: Crossover design whereby subjects walked under 2 ifferent insole conditions: a 0° control wedge and a 6° lateral edge. Setting: A gait laboratory with 3-dimensional motion analsis and force platform equipment. Participants:...

OBJECTIVE To analyse sports activities of patients with hip or knee osteoarthritis (OA) over lifetime, preoperatively, and 5 years after arthroplasty. METHODS In a longitudinal four centre study, 809 consecutive patients with advanced OA of the hip (420) or the knee (389) joint under the age of 76 years who required total joint replacement were recruited. A completed questionnaire about sport...

To discuss the method and effect of total knee arthroplasty osteotomy and soft tissue release for serious knee joint space narrowing. Clinical data of 80 patients from October 2013 to December 2014 was selected with a retrospective method. All patients have undergone total knee arthroplasty. Then the X-rays plain film in weight loading was measured before and after operation and osteotomy was p...

Although the movement of the leg during swing phase is often compared to the unforced motion of a compound pendulum, the muscles of the leg are active during swing and presumably influence its motion. To examine the roles of muscles in determining swing phase knee flexion, we developed a muscle-actuated forward dynamic simulation of the swing phase of normal gait. Joint angles and angular veloc...
