Patient-reported outcome assessment after total joint replacement: comparison of questionnaire completion times on paper and tablet computer.
Patient-reported outcome (PRO) assessment is becoming increasingly important after joint replacement surgery. However, PRO data collection, questionnaire handling, and data processing are time consuming and costly process. The aim of our study was to evaluate the efficiency of PRO assessment using tablet computers compared with traditional paper questionnaires in a total hip or knee arthroplasty (THR or TKR) population. ⋯ Electronic PRO data collection can substantially decrease time, logistics, and effort associated with questionnaire completion in daily clinical practice. It is also acceptable for use in an older arthroplasty population.

Randomized Controlled TrialEarly functional outcome of two different orthotic concepts in ankle sprains: a randomized controlled trial.
Purpose of the study was the evaluation of the early functional outcome of patients with an acute ankle sprain treated either with a semirigid, variable, phase-adapted modular ankle orthosis or an invariable orthotic reference device. ⋯ Differences between the two intervention groups were marginal and very small but significant and--regarding Cohen's effect sizes--effective. Especially relating to functional performance, this might be a careful indication that a more effective strategy for promoting a protected, rapid recovery to physical activity after ankle sprains might be achieved by applying a phase-adapted ankle orthosis. Especially in athletic patients, phase-adapted orthosis should be further investigated and considered to ensure fully protected ligament healing as well as to regain early functional recovery.

Titanium-nickel shape memory alloy (Ti-Ni SMA) is characterized by shape-memory effect, super-elasticity, excellent fatigue behavior, corrosion resistance, acceptable biocompatibility and high damping capacity. ⋯ The Ti-Ni SMA-claw fixator produced good osteosynthesis effect by continuous recovery stress with relatively simple and minimally invasive handling process, which can be introduced as an alternative to traditional tension band technique for treatment of patellar transverse fracture.

Cast-treated distal radius fractures: a prospective cohort study of radiological outcomes and their association with impaired calcaneal bone mineral density.
We hypothesized that treating distal radius fractures with cast only or closed reduction and cast is associated with high malunion risk and that the risk is higher in patients with low bone mineral density (BMD). ⋯ Closed reduction and cast is not an effective treatment for distal radius fractures if radiological graphic outcomes are considered. There is a higher risk of malunion involving dorsal and radial tilt in patients with osteoporosis. Calcaneal BMD measurement may have some benefit in predicting the risk of severe malunion.

The size of tibial footprint of anterior cruciate ligament and association with physical characteristics in Asian females.
The tibial footprint is important for preoperative planning of operative technique and graft selection. Knowledge of tibial footprint in Asians is scant including the relationship between tibial footprint and physical characteristics. The aim of this study was to identify the size of the anterior cruciate ligament (ACL) tibial footprint and the proportion of size <14 mm, and to evaluate the association of tibial footprint with physical characteristics in Asian females. ⋯ Tibial footprint size shows a large variation with a high proportion of <14 mm length. Tibial length can help predict the ACL tibial footprint in the preoperative planning of ACL reconstruction.
