PURPOSE The primary stability of 5 new knotless suture anchors was compared in healthy and osteopenic humeri by use of the following anchor systems: Opus Magnum 2 (ArthroCare, Austin, TX), PushLock (Arthrex, Naples, FL), SwiveLock (Arthrex), Kinsa RC (Smith & Nephew, London, England), and Versalok (DePuy Mitek, Raynham, MA). METHODS Twenty healthy and 20(More)
PURPOSE The purpose was to evaluate whether the knot security of sliding and nonsliding knots with different sutures is influenced by dry or wet conditions. METHODS We tested 5 suture materials, all of them US Pharmacopeia No. 2: PDS (polydioxanone) II (Ethicon, Somerville, NJ), Ethibond (Ethicon), and 3 ultrahigh-molecular weight polyethylene (UHMWPE)(More)
INTRODUCTION Rotator cuff tears are increasing with age. Does osteopenic bone have an influence on the pullout strength of suture anchors? MATERIALS AND METHODS SPIRALOK 5.0 mm (DePuy Mitek), Super Revo 5 mm and UltraSorb (both ConMed Linvatec) suture anchors were tested in six osteopenic and six healthy human cadaveric humeri. Incremental cyclic loading(More)
PURPOSE Excellent long-term results have been reported for implantation of unicompartmental knee arthroplasty (UKA). In many patients the desire for improvement in function often includes an aspiration to return to sports. The purpose of our study was to evaluate physical activities after medial Oxford-III (Biomet) UKA surgery. METHODS Patients' physical(More)
The aim of this study is the investigation of the clinical results after third generation autologous chondrocyte implantation in the knee in a follow-up over three years post-operation. Our primary focus is on the effects of this procedure on children and adolescent patients as there is a lack of knowledge regarding the clinical outcomes in(More)
PURPOSE Third generation autologous chondrocyte implantation (ACI) is an established treatment for full thickness cartilage defects in the knee joint. However, little is known about cases when revision surgery is needed. The aim of the present study is to investigate the complication rates and the main reasons for revision surgery after third generation(More)
The study, aiming to document the effect of continued support for mothers on frequency of exclusive breast feeding, was carried out by inclusion of breast feeding counselling in the context of well-baby care. One hundred and forty-six mothers who had been exposed to two educational sessions on breast feeding after delivery were given appointments to bring(More)
BACKGROUND Graft hypertrophy is the most common complication of periosteal autologous chondrocyte implantation (p-ACI). PURPOSE The aim of this prospective study was to analyze the development, the incidence rate, and the persistence of graft hypertrophy after matrix-based autologous chondrocyte implantation (mb-ACI) in the knee joint within a 2-year(More)
BACKGROUND Third-generation autologous chondrocyte implantation (ACI) is an established method for treatment of full-thickness cartilage defects in the knee joint. Subchondral bone marrow edema (BME) is frequently observed after ACI, with unknown pathogenesis and clinical relevance. PURPOSE To investigate the occurrence and clinical relevance of BME after(More)
PURPOSE Rotator cuff tears are challenging as the rate of re-ruptures remains high. Thus, new therapeutic strategies need to be developed. Tendon in situ regeneration (TSR) attempts to produce cell-scaffold constructs in vitro, which can produce tendinous tissue of high quality after replantation. Therefore, it is essential to find suitable scaffolds that(More)
