An enormous economic impact can be observed for infected total knee arthroplasties (TKA). The aim of the present study was to evaluate whether a cost covering treatment TKA is feasible in German DRG System.Average costs were evaluated and compared with matched pair primary TKA. Data generated using health record hospitals' information system. Results regarding personnel material respect financial receipts.A 28 patients diagnosed an included. A significant increase average length stay, use...
Abstract Patellofemoral instability is a severe problem in young and active patients. This pathology influenced by ligamentous, bony, neuromuscular parameters. The reconstruction of the medial patellofemoral ligament (MPFL) evolved to primary procedure, but combined procedures were more frequently performed past years. However, additional operative are associated with increased morbidity no absolute indication can be identified literature. study intended clarify whether addressing only...
management of intrasubstance meniscal lesions is still controversial. Intrasubstance can lead to reduced sports activity and rupture. Physical therapy often not satisfactory. Therefore new treatment methods are requested. Platelet Rich Plasma (PRP) has the ability regenerate tissue; this was proved in several experimental studies. Whether percutaneous injections PRP effective unknown. We hypothesize that pain relief halt progression on MRI over 6 months patients with grade 2 lesions.ten...
Background: Anatomic features of the tibial plateau (ie, posterior slope and medial concavity) have been associated with an increased risk anterior cruciate ligament (ACL) injuries. However, it remains unclear whether these findings translate to ACL injuries sustained during recreational alpine skiing. Purpose: To investigate association in skiers between prominent morphological (slope sustaining injury a noncontact incident. Study Design: Case-control study; Level evidence, 3. Methods:...
Implant-associated infections are dangerous complications and may cause dramatic illness with hematogeneous spread of bacteria secondary infections. Since treatment these remains most challenging commonly requires implant removal, prevention is utmost importance. In the present work a titania-sol was equipped copper salt resulting after calcination in titania coating (TiO2) antibacterial properties combined good cytocompatibility. vitro tests as well tissue cells were carried out under...
Septic loosening of total hip and knee endoprostheses gains an increasing proportion revision arthroplasties. Operative revisions infected are mentally physically wearing for the patient, challenging surgeon a significant economic burden healthcare systems. In cases early infection within first three weeks after implantation one-stage with leaving implant in place is widely accepted. The recommendations management late infections vary by far. One-stage as well two-stage or multiple schedules...
By means of plasma polymerization, positively charged, nanometre-thin coatings can be applied to implant surfaces. The aim the present study was quantify adhesion human bone cells in vitro and evaluate ongrowth vivo, on titanium surfaces modified by polymer coatings. Different surface configurations were examined: alloy (Ti6Al4V) coated with plasma-polymerized allylamine (PPAAm) ethylenediamine (PPEDA) versus uncoated. Shear stress osteoblast-like MG-63 investigated using a spinning disc...
Objective . Implant‐associated infections remain serious complications in orthopaedic and trauma surgery. A main scientific focus has thus been drawn to the development of anti‐infective implant coatings. Animal models implant‐associated are considered helpful vivo testing new The aim present study was evaluate a novel animal model for generation tibial metaphysis rats. Materials Methods custom‐made conical made Ti6Al4V inserted bilaterally at medial proximal tibia 26 female Sprague‐Dawley...
New developments of antimicrobial implant surfaces doped with copper (Cu) ions may minimize the risk implant-associated infections. However, experimental evaluation Cu release is influenced by various test parameters. The aim our study was to evaluate characteristics in vitro according storage fluid and surface roughness. Plasma immersion ion implantation (Cu-PIII) pulsed magnetron sputtering process a titanium film (Ti-Cu) were applied alloy (Ti6Al4V) samples different finishing material...
ABSTRACT Implant osseointegration can currently only be assessed reliably post mortem. A novel method that relies on the principle of acoustic sound analysis was developed to enable examination longitudinal progress osseointegration. The is based a magnetic sphere inside hollow cylinder implant. By excitation using an external field, collision implant produces signal. Custom‐made titanium implants equipped thusly were inserted in each lateral femoral epicondyle 20 New Zealand White Rabbits....
Anteromedial knee injury with rupture of anterior cruciate ligament (ACL) and concomitant lesion medial collateral (MCL) is common in athletes. No standardized treatment concept can be found within the literature. This study presents results a new for MCL lesions patients ACL rupture. In this study, 67 recreational athletes were treated according to distinct concept. Patients classified six different types depending on grade presence anteromedial rotatory instability (AMRI). Final...
A common method to derive both qualitative and quantitative data evaluate osseointegration of implants is histomorphometry. The present study describes a new image reconstruction algorithm comparing the results bone-to-implant contact (BIC) evaluated by means µCT with histomorphometry data. Custom-made conical titanium alloyed (Ti6Al4V) were inserted in distal tibial bone female Sprague-Dawley rats. Different surface configurations examined: Ti6Al4V plasma-polymerized allylamine (PPAAm)...
Implant infection remains a feared complication after total hip replacement. A higher rate of is observed revision surgery. An additional threat for such patients arises from the fact that bacteria resistant to multitude antibiotics are encountered with increasing frequency in hospital setting. Among them enterobacteria producing extended spectrum β-lactamases (ESBL) second most frequent group multiresistant isolates. ESBLs enzymes which hydrolyse third and fourth generation cephalosporins...
Abstract Introduction The pathology of a mucoid degeneration the anterior cruciate ligament (MDACL) has been mentioned in several publications but due to its rare incidence it is not well-known pathology. Partial or complete resection ACL option choice after failed non-surgical treatment. However, success rate both surgical techniques and subsequent risk an instability known. purpose this study was compare clinical radiological outcome between partial patients with MDACL. Materials methods...
Abstract Nowadays total joint replacement is an indispensable component of modern medicine. The surfaces characteristics cementless prostheses may be altered to achieve accelerated and enduring bony integration. Classic surface coatings bear the risk loosening or flaking from implant body. This excluded by chemical conversion naturally existing TiO 2 layer into calcium titanate. aim this experimental animal study was investigate integration implants with a new titanate (Ca 4 Ti 3 O 10 )...
