Introduction: Patient oriented research (POR) invites patients to partner with researchers, clinicians, and other stakeholders, incorporating diverse perspectives to generate scientific evidence meaningful to all parties involved. We adopted a POR approach for this study evaluating the feasibility of conducting a randomized control trial of a novel tri-compartment offloader brace for knee osteoarthritis. We involved patients as partners to enhance study design, implementation and interpretation of key outcomes.

The Levitation tricompartment offloader (TCO) knee brace provides an assistive knee extension moment with the goal of unloading all three compartments of the knee and reducing pain for individuals with multicompartment knee osteoarthritis (OA). This study aimed to determine the effect of the TCO brace on sagittal plane knee moments, quadriceps muscle activity, and pain in individuals with multicompartment knee OA. Lower limb kinematics, kinetics, and electromyography data were collected during a chair rise and lower to determine differences between bracing conditions.

The levitation tricompartment offloader (TCO) brace is designed to unload all three knee compartments by reducing compressive forces caused by muscle contraction. This study aimed to determine the effect of the TCO on knee contact forces and quadriceps muscle activity in individuals with knee osteoarthritis. Lower limb kinematics, kinetics, and electromyography data were collected during a chair rise-and-lower task.

Purpose: Traditional knee osteoarthritis (OA) braces are usually indicated for a minority of patients with knee OA, as they are only suitable for those with unicompartmental disease affecting the tibiofemoral joint. A new assistive brace design is intended for use in a wider range of knee OA patients with heterogeneous symptoms characteristic of patellofemoral, tibiofemoral, or multicompartmental knee OA. The purpose of this case series was to explore whether the use of this novel "tricompartment offloader" (TCO) brace was associated with clinically relevant improvements in pain and function.

Simulation-based educational activities are happening in the clinical environment but are not all uniform in terms of their objectives, delivery, or outputs. While these activities all provide an opportunity for individual and team training, nuances in the location, timing, notification, and participants impact the potential outcomes of these sessions and objectives achieved. In light of this, there are actually many different types of simulation-based activity that occur in the clinical environment, which has previously all been grouped together as "in situ" simulation.

Background: The increasing burden of illness related to musculoskeletal diseases makes it essential that attention be paid to musculoskeletal education in medical schools. This case study examines the undergraduate musculoskeletal curriculum at one medical school.

Methods: A case study research methodology used quantitative and qualitative approaches to systematically examine the undergraduate musculoskeletal course at the University of Calgary (Alberta, Canada) Faculty of Medicine.

We present four cases of glomus tumors presenting as knee pain. All cases were treated by surgical excision of the tumor. All patients made an immediate recovery with return to full normal function.

The purpose of this study was to determine the diagnostic ability of magnetic resonance imaging (MRI) compared with a reference standard, arthroscopy, in patients presenting with shoulder pain consistent with the signs and symptoms of shoulder impingement. Fifty-eight patients in whom conservative management failed underwent standardized MRI with intravenous gadolinium enhancement and arthroscopic evaluation. The prevalence of supraspinatus tendon, long head of the biceps tendon, and acromioclavicular joint pathology in this population was high: 79.

Previous research has established a link between childhood sexual abuse and engaging in prostitution as an adult. The purpose of this study was to extend this literature by exploring whether being raped as an adult is associated with exchanging sex for money. Interviews with 102 rape survivors in a major metropolitan area revealed that 23.
