Do we really improve life quality after total knee arthroplasty in patients with Parkinson's disease?
The knee in Parkinson's disease (PD) patients is a problematic joint due to pain, stiffness and gait instability. The aim of this study is to evaluate the functional outcome and degree of pain relief achieved after total knee arthroplasty (TKA) in PD patients. ⋯ TKA successfully provided pain relief in PD patients. However, the functional outcome is related to disease progression and, therefore, variable. Perioperative complications are difficult to avoid and manage.

Higher revision rate for posterior cruciate-retaining than posterior-stabilized total knee arthroplasty for the treatment of valgus osteoarthritis.
Determining the point at which a valgus deformity requires a more invasive therapy-in this case PS TKA-is surgically challenging. Retaining the posterior cruciate ligament has both advantages and disadvantages. The aim was to evaluate the failure rate and clinical outcomes. ⋯ No difference in the clinical outcome between the CR and PS TKA patients was found. In the CR group, significantly more patients showed 'excellent' OKS than in the PS group. However, 8.0% of the patients in the CR group and none in the PS group underwent surgery due to instability. A higher rate of dissatisfied patients in the CR group is likely. In our clinic, we no longer perform CR TKA for valgus cases.

Radio-luno-triquetral bone-ligament transfer as an additional stabilizer in scapholunate-instability.
Reconstruction of the scapho-lunate (SL) ligament is still challenging. Many different techniques, such as capsulodesis, tendon graft and bone-ligament-bone graft have been described to stabilize reducible SL dissociation. If primary ligament repair alone is not possible, an additional stabilizer is needed to achieve scapho-lunate stability. A new local bone-ligament transfer using half of the radio-luno-triquetral ligament is performed. The direction of traction of the transposed ligament is very similar to the original ligament. Ideal tension can be attained by fixation of the bone block at the dorsal ridge of the scaphoid. The biomechanical stability of this bone-ligament transfer shall be examined biomechanically. ⋯ Level II, therapeutic investigating experimental study.

Does performing total joint arthroplasty in the afternoon or evening increase the risk of prosthetic joint infection?
Does performing total joint arthroplasty in the afternoon or evening increase the rate of early prosthetic joint infection and the likelihood of early prosthetic joint infection? ⋯ Performing total joint arthroplasty in the afternoon or in the evening, after aseptic cases does not increase the risk of subsequent of PJI.

Kaplan fibers (KF) have been described as connections between the iliotibial band and the distal femur. They are divided into two distinct structures, proximal (PKF) and distal (DKF) fibers, which may participate in the control of the rotatory knee stability. Their anatomical characteristics have not been investigated completely, in particular with respect to reconstruction procedures. The aim was to determine their anatomical characteristics and their morphological variation. ⋯ PKF and DKF are distinct and constant anatomical structures of the lateral compartment of the knee, whose anatomical characteristics and their tensioning in IR presume a function of controlling rotational knee stability.
