Randomized Controlled TrialCan local infiltration analgesia increase satisfaction in postoperative short-term pain control in total knee arthroplasty?
One of the major challenges to total knee arthroplasty (TKA) is optimal pain control. Effective analgesia is capital in fast-track surgery programs to allow patient's early functional outcomes. ⋯ LIA is a safe adjuvant to FNB to reduce perioperative pain during the first 36 h after TKA. Its effects wean with time, but do cover the first crucial hours of rehabilitation in a fast-track program. LIA seems don't modify postoperative course nor patient's satisfaction at short-term follow-up. The final impact of LIA on surgical outcome is still to be determined.

Multicenter StudyProposal of new classification of femoral trochanteric fracture by three-dimensional computed tomography and relationship to usual plain X-ray classification.
Classification of femoral trochanteric fractures is usually based on plain X-ray findings using the Evans, Jensen, or AO/OTA classification. However, complications such as nonunion and cut out of the lag screw or blade are seen even in stable fracture. This may be due to the difficulty of exact diagnosis of fracture pattern in plain X-ray. Computed tomography (CT) may provide more information about the fracture pattern, but such data are scarce. In the present study, it was performed to propose a classification system for femoral trochanteric fractures using three-dimensional CT (3D-CT) and investigate the relationship between this classification and conventional plain X-ray classification. ⋯ It is difficult to evaluate fracture patterns involving the greater trochanter, especially large oblique fragments including the lesser trochanter, using plain X-rays. The 3D-CT shows the fracture line very clearly, making it easy to classify the fracture pattern.

Subtalar arthroscopy and fluoroscopy in percutaneous fixation of intra-articular calcaneal fractures.
Percutaneous fixation of intra-articular calcaneal fractures is traditionally assisted only by intraoperative fluoroscopy. Previous studies have demonstrated that the additional use of subtalar arthroscopy in anatomical reduction of the posterior calcaneal facet of the subtalar joint for less complex calcaneal fractures yielded positive results up to 2-year follow-up. This study aims to investigate long-term outcomes of these patients using similar evaluation parameters. We hypothesized that this novel technique with dual-imaging can provide sustainable, long-term benefits with good functional outcomes and significant restoration of the Bohler's angle. ⋯ Subtalar arthroscopy with intraoperative fluoroscopy in anatomical reduction of the posterior calcaneal facet of the subtalar joint is most useful in Sanders type II, AO-OTA 83-C2 fractures with excellent functional outcomes and good preservation of the corrected Bohler's angle on long-term follow-up.

The relationship between radiological alignment of united distal radius fractures and functional and patient-perceived outcomes in elderly patients.
The purpose of this study was to investigate the relationship between radiological alignment and functional outcomes including strength, range of motion (ROM), and disabilities of the arm, shoulder, and hand (DASH) and patient-rated wrist evaluation (PRWE) scores in elderly patients with united distal radius fractures. ⋯ This study suggests that minor deformities of the distal radius following distal radius fractures treated with either operative or nonoperative treatment are unlikely to be clinically relevant and have no impact on patient perceived outcomes for elderly patients.

A new technique for arthroscopic reduction and fixation of displaced tibial intercondylar eminence fractures, using suture anchor and EndoButton system.
The study aims to describe a less invasive technique for displaced tibial intercondylar eminence fractures, using only one bone tunnel with suture anchor and EndoButton system. ⋯ The study demonstrated that the procedure is safe and effective, which can be another option for tibial intercondylar eminence fractures.
