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 ...

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.

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...

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...

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...

Open AccessSurgically modifiable factors measured by computer-navigation together with patient-specific factors predict knee society score after total knee arthroplasty
The purpose was to investigate whether patient-specific factors (PSF) and surgically modifiable factors (SMF), measured by means of a computer-assisted navigation system, can predict the Knee Society Scores (K...

Regional differences in temperature course after knee arthroplasty
During wound healing after surgery, physiological inflammation leads to an increase in soft tissue perfusion. This is reflected by a characteristic temperature course in the skin. Although local surgical trau...

The reversed gap technique produces anatomical alignment with less midflexion instability in total knee arthroplasty: a prospective randomized trial
No surgical technique is capable of controlling the stability of the joint in midflexion. The purpose of the present study was to present and evaluate a surgical technique that aims to reduce the need for soft...

The C-reactive protein level after total knee arthroplasty is gender specific
Laboratory diagnostics are part of the routine before and after operations. In all specialist surgical disciplines, including orthopaedic surgery, the acute-phase protein CRP is used to detect inflammatory pro...

Patient-specific and intra-operatively modifiable factors assessed by computer navigation predict maximal knee flexion one year after TKA
There are multiple factors affecting maximal knee flexion (MKF) after total knee arthroplasty (TKA). The aim of the study was to investigate whether patient-specific factors (PSF) and surgically modifiable fac...

Good clinical and radiological results of total knee arthroplasty using varus valgus constrained or rotating hinge implants in ligamentous laxity
The optimal degree of constraint of a total knee arthroplasty for treatment of knee osteoarthritis with ligamentous laxity is under debate. While varus valgus constrained knees require a minimum level of ligam...

Effect of additional distal femoral resection on flexion deformity in posterior-stabilized total knee arthroplasty
Flexion deformity after total knee arthroplasty (TKA) is associated with poor function and dissatisfaction and should, therefore, be avoided. In the case of preoperative flexion deformity, an increased distal ...

Salvage-Optionen bei persistierendem Infekt nach Knietotalendoprothese
Die persistierende periprothetische Infektion stellt bis heute die Endoprothetik vor viele Probleme. Laut Endoprothesenregister Deutschland (EPRD) 2020 mussten 14,5 % der Knieprothesen wegen einer Infektion re...
