Long-term sequelae of septic arthritis after tibial plateau fracture fixation: does timing matter?
Septic arthritis following surgical treatment of a tibial plateau fracture is a rare complication, but it does occur, and the impact on long-term function is relatively unknown. The purpose of this study was to determine the long-term sequelae of septic arthritis among patients treated with internal fixation for a tibial plateau fracture and to determine the effect of timing (early or late infection) on the rate of such sequela. ⋯ III.

Do hip-abduction braces work?-A biomechanical evaluation of a commercially available hip brace.
Dislocations of the hip joint are a common and clinically relevant complication following total hip arthroplasty (THA). Hip-abduction braces are currently used following operative or non-operative treatment of THA dislocations to prevent re-dislocations. However, the clinical and biomechanical effectiveness of such braces is still controversial. ⋯ This study has demonstrated that hip-abduction braces reduce hip range of motion. However, we also found that to achieve a flexion limitation of the hip to 90°, the hip brace should be set at a 70° hip flexion limitation.

Additional coracoclavicular augmentation reduces revision rates in the treatment of lateral clavicle fractures as compared to angle-stable plate osteosynthesis alone.
There is no uniform approach to the management of lateral clavicle fractures. Recent studies have investigated additive coracoclavicular (CC) augmentation as a treatment option; however, it is unclear whether it is superior to conventional locking plate osteosynthesis. ⋯ Additive CC augmentation in combination with locking plate osteosynthesis seems to improve the vertical stability and reduces the revision rate in patients with a lateral clavicle fracture. Furthermore, an arthroscopy-assisted procedure allows for an intraoperative detection and single-step treatment of accompanying intraarticular pathologies.

Impact of femoro-tibial size combinations and TKA design on kinematics.
The variability in patients' femoral and tibial anatomy requires to use different tibia component sizes with the same femoral component size. These size combinations are allowed by manufacturers, but the clinical impact remains unclear. Therefore, the goals of our study were to investigate whether combining different sizes has an impact on the kinematics for two well-established knee systems and to compare these systems' kinematics to the native kinematics. ⋯ TKA systems designed with a constant tibio-femoral congruency among size combinations should enable to combine different sizes without having substantial impact on the kinematics. The rotational pattern was preserved by both TKA systems, while the rollback could only be maintained by the PS design.
