BACKGROUND Bone microarchitecture is a significant determinant of bone strength. So far, the assessment of bone microarchitecture has required bone biopsies, limiting its utilization in clinical practice to one single skeletal site. With the advance of high-resolution imaging techniques, non-invasive in vivo measurement of bone microarchitecture has recently become possible. This provides an op...

Previous research indicates that both the extent and timing of muscular activation at the knee can be influenced by muscle activity state, joint angle, weight-bearing status and trunk position. However, little research to date has evaluated protective neuromuscular response times and activation patterns to an imposed perturbation with the knee joint in a functional, weight-bearing stance. Hence...

background: autogenous osteochondral grafting of articular defect in weight-bearing surface of large joints has proven to be a proper biomechanical and physiological solution for localized full-thickness defects. objective: to study the gross and histopathological results of mosaicplasty in an animal model (sheep’s medial femoral condyle), evaluating the factors of defect and graft size, assess...

QUESTION What is the feasibility and effectiveness of a novel weight-bearing strengthening program compared with that of a traditional non-weight-bearing strengthening program for older inpatients undergoing rehabilitation? DESIGN Randomised, controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis. PARTICIPANTS Eighty-eight inpatients (11% loss to foll...

Tibial fracture is the most common long bone fracture. Because of the superficial location of the tibia, surgery is usually required for the treatment of fractures to achieve union. The goal of this study was to evaluate the effect of decortication on the faster union of fractures treated with compression plates. In this clinical trial, conducted from 2009 to 2013, 42 patients were randomly ass...

BACKGROUND A study was conducted to determine the reliability and minimal detectable change for a new composite measure of the vertical and medial-lateral mobility of the midfoot called the foot mobility magnitude. METHODS Three hundred and forty-five healthy participants volunteered to take part in the study. The change in dorsal arch height between weight bearing and non-weight bearing as w...

Biofeedback devices are increasingly used to train orthopedic patients to comply with partial weight-bearing instructions for an injured or postoperative extremity. In a previous study, the authors showed that biofeedback was effective in training young participants. However, because many partial weight-bearing orthopedic patients are of advanced age, the current study was designed to test the ...

Knee range of motion was determined in 60 patients to assess the effect of weight bearing on maximal knee flexion. Three patient subgroups were investigated: patients with normal knees, patients implanted with posterior cruciate-retaining (PCR) total knee arthroplasty (TKA), and patients implanted with posterior cruciate-substituting (PS) TKA. Maximal knee flexion was determined using videofluo...

BACKGROUND AND PURPOSE There is no consensus on the best rehabilitation regime after uncemented total hip arthroplasty. Theoretically, bone ingrowth into the implant should benefit from initial partial weight bearing. We investigated whether the degree of postoperative weight bearing influences the periprosthetic bone mineral density (BMD) and/or the stability of the CLS stem. PATIENTS AND ME...

STUDY DESIGN Measurements, descriptive. OBJECTIVES To describe a weight-bearing method to assess bilateral hip abductor and external rotator muscle performance. BACKGROUND The hip abductors and external rotators are important in maintaining lower extremity alignment during weight-bearing tasks. As such, there is a need for a method to assess hip muscle performance in weight bearing. METHO...
