Matrix-associated autologous chondrocyte transplantation/implantation (MACT/MACI) is a new operation procedure using a cell seeded collagen matrix for the treatment of localized full-thickness cartilage defects. A prospective clinical investigation was carried out in order to clarify whether this proves suitable and confirms objective and subjective(More)
BACKGROUND Radial extracorporeal shock wave therapy is an effective treatment for chronic plantar fasciitis that can be administered to outpatients without anesthesia but has not yet been evaluated in controlled trials. HYPOTHESIS There is no difference in effectiveness between radial extracorporeal shock wave therapy and placebo in the treatment of(More)
The Ligg. coracohumerale and coracoglenoidale are constant anatomical structures, represented in all the 34preparations investigated. The Lig. coracoglenoidale is a strong band of dense connective tissue, running from the Processus coracoideus to the Tuberculum supraglenoidale. In 27 specimens out of 34 it was the continuation of the M. pectoralis minor(More)
BACKGROUND The optimal treatment strategy following primary total hip or knee replacement remains unknown. The purpose of this study was to evaluate the effect of ergometer cycling after hip or knee replacement surgery on health-related quality of life and patient satisfaction. METHODS Three hundred and sixty-two patients were randomly assigned to either(More)
Hyaline articular cartilage is a specialised connective tissue with weight bearing and adsorbing functions. Injury or loss of which often leads to impaired joint function and severe pain. Since the self-renewing abilities of hyaline articular cartilage are limited, there is major interest in the development of bioengineered cartilaginous implants. A(More)
Twelve right cadaver shoulder joints were investigated after alcohol-formalin-glycerol fixation. The tendons of the "rotator cuff" were separated from the joint capsule. The capsulo-ligamentous structures: Lig. coracohumerale, Lig. coracoglenoidale and Ligg. glenohumeralia were dissected. In addition to the Ligg. glenohumerale superius, medium et inferius,(More)
The regenerative capacity of hyaline articular cartilage is limited. Thus, lesions of this tissue are a proarthrotic factor, and up to now the conservative treatment of cartilage lesions and arthrosis does not yield satisfying results. Therefore, autologous transplantation of articular chondrocytes is being investigated in a variety of different assays. The(More)
The triangular capsular space between the insertion tendons of the Mm. supraspinatus and subscapularis--the "rotator interval", can be divided into lateral, medio-superior and medio-inferior parts. The lateral part of the capsule is strengthened by the "Lig. semicirculare humeri" and the anterior fibres of the M. supraspinatus tendon. The Ligg.(More)
INTRODUCTION We studied the migration pattern, morphology and viability of cells suspended in five different fibrin glues. Besides this, the behaviour of chondrocytes seeded on porous matrices comprising different collagen types sealed with fibrin glue was investigated. MATERIAL AND METHODS In an experiment A, cell suspension (0.5x10(6) cells) was(More)
OBJECTIVE The aim of this study was to evaluate the regenerative potential of cell-laden and cell-free collagen matrices in comparison to microfracture treatment applied to full-thickness chondral defects in an ovine model. METHODS Animals (n = 30) were randomized into 5 treatment groups, and 7-mm full-cartilage-thickness defects were set at the trochlea(More)
