BACKGROUND: Outcomes assessment after the treatment of shoulder disorders has involved the use of various condition-specific outcome instruments. The purpose of this study was to determine the psychometric properties of the American Shoulder and Elbow Surgeons subjective shoulder scale in patients with shoulder instability, rotator cuff disease, and glenohumeral arthritis.

METHODS: Test-retest reliability, internal consistency, content validity, criterion validity, construct validity, ...

BACKGROUND: A child who has an acutely irritable hip can pose a diagnostic challenge. The purposes of this study were to determine the diagnostic value of presenting variables for differentiating between septic arthritis and transient synovitis of the hip in children and to develop an evidence-based clinical prediction algorithm for this differentiation.

METHODS: We retrospectively reviewed the cases of children who were evaluated at a major tertiary-care children's hospital between 1979 ...

BACKGROUND: The Lysholm knee scale is a condition-specific outcome measure that was originally designed to assess ligament injuries of the knee. The purpose of this study was to determine the psychometric properties of the Lysholm knee scale for various chondral disorders of the knee.

METHODS: Test-retest reliability, internal consistency, content validity, criterion validity, construct validity, and responsiveness to change were determined for the Lysholm knee scale within subsets of an ...

BACKGROUND: The challenge of cost-efficiency is maintaining the quality of medical care while reducing costs and eliminating unnecessary practices. The purpose of this investigation was to evaluate the cost and effectiveness of routine pathological examination of surgical specimens from patients undergoing primary total hip or knee replacement for the treatment of osteoarthritis.

METHODS: Effectiveness was assessed by comparing clinical and pathological diagnoses associated with 1,234 ...

BACKGROUND: In 1982, the Lysholm score was first published as a physician-administered score in the American Journal of Sports Medicine. The Tegner activity scale was published in 1985.

HYPOTHESIS: The Lysholm and Tegner scores are valid as patient-administered scores and responsive at early time points after treatment of anterior cruciate ligament tears.

STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 1.

METHODS: All patients were treated for an anterior cruciate ligament ...

OBJECTIVE: To estimate the incidence proportion (IP) and incidence rate (IR) for ACL injury in athletes.

DESIGN: Systematic review with meta-analysis DATA SOURCES: The PubMed, CINAHL and SPORTDiscus electronic databases were searched from inception to 20 January 2017.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies were included if they reported total number of participants/population by sex, total number of ACL injuries by sex and total person-time by sex.

RESULTS: Fifty-eight ...

Twenty-four patients had reconstruction of the distal aspect of the radius with use of an osteoarticular allograft, between 1974 and 1992, after excision of a giant-cell tumor (twenty patients), a desmoplastic fibroma (two patients), a chondrosarcoma (one patient), or an angiosarcoma (one patient). Nine giant-cell tumors were recurrent lesions, and eleven were extracompartmental primary lesions that had extended through the cortex or subchondral bone. The average age of the patients was ...

INTRODUCTION: Arthrofibrosis is a known complication after anterior cruciate ligament (ACL) reconstruction. ACL reconstruction is being performed with increased frequency in the pediatric population. The purpose of this study was to determine the prevalence of arthrofibrosis in children and adolescents and to identify risk factors for arthrofibrosis.

METHODS: The study design was a retrospective case series. Medical records for 1016 consecutive ACL reconstructions in patients aged 7 to ...

BACKGROUND: A torn meniscus is one of the most common indications for knee surgery. The purpose of this study was to determine the psychometric properties of the Lysholm knee score and the Tegner activity scale when used for patients with a meniscal injury of the knee.

METHODS: Test-retest reliability, content validity, criterion validity, construct validity, and responsiveness to change were determined for the Lysholm score and the Tegner activity scale. Test-retest reliability was ...

BACKGROUND: Closed reduction and percutaneous pin fixation is the treatment of choice for completely displaced (type-III) extension supracondylar fractures of the humerus in children, although controversy persists regarding the optimal pin-fixation technique. The purpose of this study was to compare the efficacy of lateral entry pin fixation with that of medial and lateral entry pin fixation for the operative treatment of completely displaced extension supracondylar fractures of the ...

There has been a decrease in the overall injury rate and the rate of lower extremity injuries for alpine skiing, with a resultant increase in the ratio of upper extremity to lower extremity injuries. Upper extremity injuries account for 20 to 35% of all injuries during alpine skiing and nearly 50% of all injuries during snowboarding. The most common upper extremity injuries during skiing are sprain of the thumb metacarpal-phalangeal joint ulnar collateral ligament, and the most common in ...

BACKGROUND: The differentiation between septic arthritis and transient synovitis of the hip in children can be difficult. The purpose of the present study was to validate a previously published clinical prediction rule for this differentiation in a new patient population.

METHODS: We prospectively studied children who presented to a major children's hospital between 1997 and 2002 with an acutely irritable hip. As in the previous study, diagnoses of septic arthritis (fifty-one patients) ...

BACKGROUND: The International Knee Documentation Committee (IKDC) Subjective Knee Form is a knee-specific measure of symptoms, function, and sports activity. A modified IKDC Subjective Knee Form (pedi-IKDC) has been developed for use in children and adolescents. The purpose of this study was to determine the psychometric characteristics of the pedi-IKDC in children and adolescents with knee disorders.

HYPOTHESIS: The pedi-IKDC is a reliable, valid, and responsive patient-administered ...

PURPOSE: The purpose of this study was to develop a self-administered evaluative tool to measure health-related quality of life in young, active patients with hip disorders.

METHODS: This outcome measure was developed for active patients (aged 18 to 60 years, Tegner activity level ≥ 4) presenting with a variety of symptomatic hip conditions. This multicenter study recruited patients from international hip arthroscopy and arthroplasty surgeon practices. The outcome was created using a ...
