Cross-cultural adaptation and validation of the Arabic version of the Western Ontario Shoulder Instability Index (WOSI-Arabic).

Background: One of the self-assessment tools used in shoulder instability to evaluate patient's quality of life is the Western Ontario Shoulder Instability (WOSI) Index. It is a valid and reliable disease-specific tool that has been translated into many languages. The aim of this study is to cross-culturally adapt the Western Ontario Shoulder Instability (WOSI) Index into Arabic and assess its psychometric properties in patients diagnosed with shoulder instability in order to help surgeons and physical therapists assess patients following an intervention.

Cross-cultural adaptation and measurement properties of an Italian version of the Western Ontario Shoulder Instability Index (WOSI).

Study Design: Clinical measurement study.

Objectives: To translate and cross-culturally adapt the Western Ontario Shoulder Instability Index (WOSI) into Italian, and to evaluate its measurement properties in patients with shoulder instability secondary to a first-time traumatic anterior dislocation.

Background: The WOSI was developed for English-speaking patients.

Cemented versus uncemented fixation of humeral components in total shoulder arthroplasty for osteoarthritis of the shoulder: a prospective, randomized, double-blind clinical trial-A JOINTs Canada Project.

Background: Although cemented humeral fixation is recognized as the standard of care in total shoulder arthroplasty (TSA), uncemented fixation has the potential to provide stable fixation, decrease operative time, and simplify potential revision procedures. This prospective, randomized, double-blind clinical trial compared cemented and uncemented humeral fixation in TSA for primary shoulder osteoarthritis.

Methods: Patients with primary shoulder osteoarthritis requiring replacement were screened for eligibility.

A randomized trial of arthroscopic surgery for osteoarthritis of the knee.

Background: The efficacy of arthroscopic surgery for the treatment of osteoarthritis of the knee is unknown.

Methods: We conducted a single-center, randomized, controlled trial of arthroscopic surgery in patients with moderate-to-severe osteoarthritis of the knee. Patients were randomly assigned to surgical lavage and arthroscopic débridement together with optimized physical and medical therapy or to treatment with physical and medical therapy alone.
