Removal and successful re-implantation of a customized interpositional knee device following an early postoperative infection: A case report
We report the first case of early postoperative infection after a medial hemiarthroplasty of the knee with a customized ConforMIS iForma™ interpositional device. The infection was treated successfully by revis...

Open AccessThe association between Femoral Tilt and im**ement-free range-of-motion in total hip arthroplasty
There is a complex interaction among acetabular component position and antetorsion of the femoral stem in determining the maximum, im**ement-free prosthetic range-of-motion (ROM) in total hip arthroplasty (T...

Irradiation in the treatment of arthrofibrosis after total knee arthroplasty: a preliminary trial
Postoperative arthrofibrosis after primary and revision total knee arthroplasty is a severe complication for the affected patient. Several risk factors have been identified for this diagnosis. We present a ser...

Regulation of gene expression in articular cells is influenced by biomechanical loading
Biomechanical stimulation enhances cell proliferation, cell differentiation and production of extracellular matrix. To what extent the gene expression of three articular cell types is affected by a defined bio...

Chemical synovectomy with sodium morrhuate in the treatment of symptomatic recurrent knee joint effusion
The aim of this study was to assess the efficacy and safety of intra-articular sodium morrhuate injections in the treatment of recurrent knee joint effusions. Ninety-eight knees of 92 patients (f = 59, m = 33) wi...

Comparing navigation-based in vivo knee kinematics pre- and postoperatively between a cruciate-retaining and a cruciate-substituting implant
Individual physiological knee kinematics are highly variable in normal knees and are altered following cruciate-substituting (PS) and cruciate-retaining (CR) total knee arthroplasty (TKA). We wanted to know wh...

Assessing patient-oriented results after revision total knee arthroplasty
Revision total knee arthroplasties (TKA) have been performed with increasing frequency over the last 25 years.

Accuracy of bony landmarks for restoring the natural joint line in revision knee surgery: an MRI study
Restoring the joint line (JL) improves clinical and functional outcome in total knee arthroplasty (TKA). Therefore, anatomical landmarks to approximate the JL have been published. So far, the natural deviation...

Predicting knee rotation by the projection overlap of the proximal fibula and tibia in long-leg radiographs
Rotation of the lower limbs in long-leg radiographs has a significant impact on imaging the mechanical femorotibial angle, the femoral anatomic mechanical angle, the mechanical lateral distal femoral angle (mL...

Pinless navigation in total knee arthroplasty: Navigation reduced by the maximum?
Restoring a neutral mechanical axis in total knee arthroplasty (TKA) (within ±3° of varus/valgus) is associated with superior functional outcome and reduced early implant failure. Using conventional alignment ...

Article
No difference between standard and high flexion cruciate retaining total knee arthroplasty: a prospective randomised controlled study
The purpose of this prospective, randomised, double-blind study was to test the hypotheses that patients with high-flexion total knee arthroplasty (TKA) have (1) a wider/greater range of motion (ROM) post-ope...

Open AccessCurrent therapeutic strategies of heterotopic ossification – a survey amongst orthopaedic and trauma departments in Germany
Heterotopic ossification (HO) is a complication after tissue trauma, fracture and surgery (i.e. total hip arthroplasty). Prophylaxis is the most effective therapy. If HO formations become symptomatic and limit...

Changes in sagittal component alignment alters patellar kinematics in TKA: an in vitro study
Patellar maltracking due to incorrect component alignment is considered as a main reason for anterior knee pain after total knee arthroplasty (TKA). In contrast to coronal and axial component placement, the in...

Article
Comparative clinical study of the prophylaxis of heterotopic ossifications after total hip arthroplasty using etoricoxib or diclofenac
This study investigated whether etoricoxib (COX-II blocker) has a superior efficacy of preventing heterotopic ossification (HO) after total hip arthroplasty (THA) compared to diclofenac (non-selective NSAID).

Decreased femoral periprosthetic bone mineral density: a comparative study using DXA in patients after cementless total hip arthroplasty with osteonecrosis of the femoral head versus primary osteoarthritis
Trabecular properties in osteonecrosis of the femoral head (ONFH) are altered for bone volume and structure in the femoral head and proximal femoral canal. We analysed the periprosthetic bone mineral density (...

Appropriate sagittal femoral component alignment cannot be ensured by intramedullary alignment rods
The intraoperative sagittal cutting block alignment when intramedullary alignment rods are used was investigated. Its absolute orthogonal orientation in relation to the mechanical femoral axis should be analy...

Article
Significant influence of rotational limb alignment parameters on patellar kinematics: an in vitro study
Component malrotation has a major impact on patellar kinematics in total knee arthroplasty. The influence of natural rotational limb alignment on patellar kinematics is unclear so far. Based on recent clinical...

Current standard rules of combined anteversion prevent prosthetic im**ement but ignore osseous contact in total hip arthroplasty
In this prospective study of 135 patients undergoing cementless total hip arthroplasty (THA) we asked whether six current definitions of combined anteversion prevent im**ement and increase postoperative pati...

Clinical, radiological and survivorship results after ten years comparing navigated and conventional total knee arthroplasty: a matched-pair analysis
Our aim was to compare the long-term outcome between navigated and conventional total knee arthroplasty (TKA), which is currently not known.
