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.

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.

Analysis of carpal kinematics after radiolunate and radioscapholunate arthrodesis shows good preservation of midcarpal joint congruity and motion. However, no biomechanical data exist on carpal kinematics after radiolunate arthrodesis in the wrist. Purpose of this study was to examine the individual motion of scaphoid, capitate and triquetrum after simulated radiolunate arthrodesis. ⋯ The presented data conform with the good clinical results obtained after radiolunate arthrodesis in the rheumatoid wrist and furthermore, encourage its use in the posttraumatic wrist.

Repair of retropatellar cartilage defects in the knee with microfracture and a cell-free polymer-based implant.
To analyze magnetic resonance imaging (MRI) at 3T and the clinical outcome in a short-term pilot study after treatment of retropatellar cartilage defects with microfracturing and subsequent covering with the cell-free chondrotissue(®) polyglycolic acid-hyaluronan implant. ⋯ IV, case series.

Randomized Controlled Trial Multicenter StudyTopical and intravenous tranexamic acid reduce blood loss compared to routine hemostasis in total knee arthroplasty: a multicenter, randomized, controlled trial.
Tranexamic acid (TXA) is becoming widely used in orthopedic surgery to reduce blood loss and transfusion requirements, but consensus is lacking regarding the optimal route and dose of administration. The aim of this study was to compare the efficacy and safety of topical and intravenous routes of TXA with routine hemostasis in patients undergoing primary total knee arthroplasty (TKA). ⋯ I.
