Massive metallosis after revision of a fractured ceramic head onto a metal head
We report a case in which metallosis occurred due to a ceramic head fracture after revision of a total hip prosthesis. In the primary revision, after retrieval of the head fragments, the firmly incorporated s...

Acute arterial occlusion after total knee arthroplasty
The duration of the ischemic time in total knee arthroplasty is currently considered to be an important predictor for the development of arterial thrombosis. In the following, we describe two patients with thr...

Two-stage operative strategy without local antibiotic treatment for infected hip arthroplasty: clinical and radiological outcome
Two-stage revision hip surgery with insertion of local antibiotic carriers is the therapy of choice for infected hip arthroplasty. The disadvantages are the incalculable pharmacokinetics of the antibiotic, wit...

Rotation of the femoral component in total knee arthroplasty—a refresher
Malrotation of the femoral component is a common cause of therapy-resistant pain after total knee arthroplasty. There is no consensus about the best technique to intraoperatively determine the correct femoral ...

Varus malalignment has no influence on clinical outcome in midterm follow-up after total knee replacement
Varus malalignment after total knee replacement is mentioned to be a major risk factor for postoperative pain and functional impairments. This wide spread opinion is based on the historical data derived from i...

The gap technique does not rotate the femur parallel to the epicondylar axis
In the analysis of painful total knee replacements, the surgical epicondylar axis (SEA) has become established as a standard in the diagnosis of femoral component rotation. It remains unclear whether the gap t...

Article
Differences in muscle trauma quantifiable in the laboratory between the minimally invasive anterolateral and transgluteal approach
In Europe the minimized transgluteal (TG) and anterolateral (AL) approaches are increasingly preferred in hip arthroplasty (THA).

Article
Kinematic analysis of the flexion axis for correct femoral component placement
This study evaluates a new method for intraoperative determination of femoral component rotation by a navigation system (flexion axis, FA) driven by joint stability over the range of motion.

Toxicity of antiseptics against chondrocytes: What is best for the cartilage in septic joint surgery?
In septic joint surgery, the most frequently used antiseptics are polyhexanide, hydrogen peroxide and taurolidine. The aim of this study was to examine the effects of these antiseptics on viability of human ch...

Thromboembolism prophylaxis with dabigatran leads to lower perioperative blood loss than with dalteparin in primary knee arthroplasty
Low-molecular-weight heparins (LMWH) are commonly used in thrombosis prophylaxis after total knee arthroplasty. In contrast to LMWH, dabigatran etexilate is an oral and direct acting anticoagulant. The hypothe...

Article
Pre-operative frontal plane malalignment predicts the extension gap asymmetry in knee osteoarthritis
In contrast to bone cuts, soft-tissue releases cannot be planned sufficiently prior to total knee arthroplasty (TKA). Intra-operative evaluation of the extension gap after tibial or femoral resection may resul...

Article
How much of the PCL is really preserved during the tibial cut?
There are two different techniques for retaining the posterior cruciate ligament (PCL) in total knee arthroplasty. The attachment of the PCL can be spared during resection of the tibial plateau, so that a smal...

Article
Increased flexion position of the femoral component reduces the flexion gap in total knee arthroplasty
The symmetry and equality of the flexion and extension gap are essential for successful endoprosthetic knee arthroplasty. Cruciate ligament sparing endoprosthetic designs are implanted with a measured resectio...

Article
The sex specificity of hip-joint muscles offers an explanation for better results in men after total hip arthroplasty
Choosing a surgical approach for total hip arthroplasty (THA) has a patient-specific impact on peri-operative muscle damage as well as postoperative functional outcome. Women and aged patients increasingly ben...

Article
Increased BMP expression in arthrofibrosis after TKA
Because of the multiple possible aetiologies of painful total knee arthroplasty (TKA), the diagnosis and treatment of such patients are challenging. In a considerable number of patients, an intraarticular path...

Osteoarthritis synovial fluid activates pro-inflammatory cytokines in primary human chondrocytes
Two of the most common joint diseases are rheumatoid arthritis (RA) and osteoarthritis (OA). Cartilage degradation and erosions are important pathogenetic mechanisms in both joint diseases and have presently g...

Evaluation of sonicate fluid cultures in comparison to histological analysis of the periprosthetic membrane for the detection of periprosthetic joint infection
The aim of this prospective study was to evaluate the diagnostic efficacy of sonicate fluid cultures (SFC) and the histological analysis of the periprosthetic membrane (PM) for the detection of periprosthetic ...

Human osteoblast damage after antiseptic treatment
Antiseptics are powerful medical agents used for wound treatment and decontamination and have a high potential for defeating joint infections in septic surgery. Both chlorhexidine and polyhexanide are frequent...

Knee Arthrodesis
Today, permanent fusion of the knee joint – knee arthrodesis – is primarily performed as a leg-sparing salvage procedure in the case of persistent joint infection after total knee arthroplasty. Persistent infe...

Intramedullary control of distal femoral resection results in precise coronal alignment in TKA
There is still a relevant rate of outliers in coronal alignment >3° when the conventional technique is used, potentially accompanied by a poorer long-term clinical outcome and a reduced longevity of the implan...
