Intraoperative soft tissue tension and postoperative range of motion in posterior stabilized total knee arthroplasty.
Intraoperative soft tissue tension can significantly impact the range of motion following total knee arthroplasty (TKA). However, the level of impact remains unclear. The purpose of this study was to investigate the relationship between intraoperative soft tissue tension and postoperative range of motion. ⋯ We did not observe a correlation between intraoperative soft tissue tension adjusted from 80 to 160 N and 1-year postoperative range of motion in posterior stabilized TKA.

Valgus osteotomy in combination with dynamic hip screw fixation for fibrous dysplasia with shepherd's crook deformity.
The treatment of fibrous dysplasia with shepherd's crook deformity is a big challenge. The purpose of this study was to investigate the clinical effect of valgus osteotomy in combination with dynamic hip screw (DHS) fixation to treat fibrous dysplasia with shepherd's crook deformity. ⋯ Our results demonstrate that valgus osteotomy in combination with DHS internal fixation is an easy and effective method for the treatment of fibrous dysplasia with shepherd's crook deformity. It can restore the neck-shaft angle and re-establish the mechanical alignment of the femur to improve function.

Review Meta AnalysisVascularized fibular grafts in patients with avascular necrosis of femoral head: a systematic review and meta-analysis.
Vascularized fibular grafting (VFG) has been initiated to treat avascular necrosis of the femoral head (ANFH) since the late 1970s. There are a number of review articles updating the use of VFG to treat the ANFH. None of them applied statistical analysis for combining results from different studies to obtain a quantitative estimate of the overall effect and potential harm of VFG in comparison to other treatment. ⋯ VFG is a justified method that can prevent the ANFH from progressing to collapse, and that can retard or avoid hip replacement, especially in the hips of Steinberg stage I, II, and III.

Comparative StudyBiomechanical comparison of intramedullar versus extramedullar stabilization of intra-articular tibial plateau fractures.
Fractures of the proximal tibia occur very often and are a great challenge for trauma surgeons to stabilize. Although locked nails were developed to stabilize these fractures, this technique has not been sufficiently investigated. The purpose of this study was to biomechanically assess the stability of locked intramedullary nailing compared to locked plating. ⋯ Nailing of proximal tibia fractures leads to a stiffer implant-bone construct than plating. Since no adverse effects were found after nailing it seems to be a good alternative to plating for intra-articular proximal tibia fractures, especially in patients with soft tissue problems.

Outcome of Autologous Matrix Induced Chondrogenesis (AMIC) in cartilage knee surgery: data of the AMIC Registry.
Autologous Matrix-Induced Chondrogenesis (AMIC) is an innovative treatment for localized full-thickness cartilage defects combining the well-known microfracturing with collagen I/III scaffold. The purpose of this analysis was to evaluate the medium-term results of this enhanced microfracture technique for the treatment of chondral lesions of the knee. ⋯ Prognostic study, Level IV.
