Patient-specific factors influencing the traction forces in hip arthroscopy.
The application of traction in hip arthroscopy is associated with peri-operative complications. Within a therapeutic case series, patient-related factors correlating with high-traction forces during hip arthroscopy and occurring complications should be identified. ⋯ The study revealed several patient-specific risk factors correlating with high-traction forces during hip arthroscopy. With view to potential complications, these patient groups require special attention during surgical treatment as well as in future studies.

Clinical and radiologic outcomes of arthroscopic suture bridge repair for the greater tuberosity fractures of the proximal humerus.
To report the clinical and radiological outcomes of arthroscopic suture bridge repair for the GT fractures of the shoulder joint. ⋯ Arthroscopic suture bridge repair was useful for the treatment of displaced GT fractures with or without comminution and the management of the combined lesions. At the final follow-up, meaningful remodeling of the GT fracture and satisfactory clinical outcomes could be achieved.

Treatment of digital pyogenic flexor tenosynovitis: single open debridement, irrigation, and primary wound closure followed by antibiotic therapy.
Digital pyogenic flexor tenosynovitis requires fast, aggressive treatment. Although this infection occurs frequently, treatment consensus is lacking. ⋯ A single open debridement with irrigation and primary wound closure followed by 10 days of antibiotic treatment resolved uncomplicated pyogenic flexor tenosynovitis. After 2 and a half years, the treatment yielded high patient satisfaction with neither functional nor subjective impairment of the affected finger.

Does a positioning rod or a patient-specific guide result in more natural femoral flexion in the concept of kinematically aligned total knee arthroplasty?
Flexion of the femoral component in 5° increments downsizes the femoral component, decreases the proximal reach and surface area of the trochlea, delays the engagement of the patella during flexion, and is associated with a higher risk of patellar-femoral instability after kinematically aligned TKA. The present study evaluated flexion of the femoral component after use of two kinematic alignment instrumentation systems. We determined whether a distal cutting block attached to a positioning rod inserted perpendicular to the distal femoral joint line in the axial plane and 8-10 cm into the distal femur anterior and posterior to the distal cortex of the femur in the sagittal plane or a femoral patient-specific cutting guide sets the femoral component in more natural flexion. ⋯ Because a distal cutting block attached to a positioning rod sets the femoral component in 5° less flexion and with less variability than a femoral patient-specific cutting guide, we prefer this instrumentation system when performing kinematically aligned TKA to reduce the risk of patellar-femoral instability. Each surgeon should determine the repeatability of setting the flexion of the femoral component with this instrumentation system.
