Assessing the measurement properties of PROMIS Computer Adaptive Tests, short forms and legacy patient reported outcome measures in patients undergoing total hip arthroplasty.

Background: The commonly used ('legacy') PROMs evaluating outcomes of total hip arthroplasty (THA), have several limitations regarding their measurement properties and interpretation of scores. One innovation in PROMs is the use of Computerized Adaptive Testing (CAT). The Patient-Reported Outcomes Measurement Information System (PROMIS) is a validated system of CATs.

The Hip Disability and Osteoarthritis Outcome Score-Physical Function Shortform Does Not Adequately Represent Physical Functioning in Patients Undergoing Total Hip Arthroplasty.

Objectives: A frequently used patient-reported outcome measure for assessing physical functioning in patients with hip problems is the 5-item Hip Disability and Osteoarthritis Outcome Score-Physical Function Shortform (HOOS-PS). Nevertheless, its content validity (whether this instrument adequately reflects the construct of physical functioning) is unknown. This study aimed to assess the content validity of the HOOS-PS.

Investigation of the efficacy and safety of ultrasoundstandardized autologous blood injection as treatment for lateral epicondylitis.

Background: There are various conservative treatment options for lateral epicondylitis (LE). The aim is to evaluate pain, daily functioning, and complications after ultrasound-standardized autologous blood injections in patients with LE.

Methods: For this prospective cohort study, consecutive patients (>18 years) diagnosed with LE were included.

Systematic review and meta-analysis of measurement properties of the Hip disability and Osteoarthritis Outcome Score - Physical Function Shortform (HOOS-PS) and the Knee Injury and Osteoarthritis Outcome Score - Physical Function Shortform (KOOS-PS).

Objective: The aim of this systematic review and meta-analysis was to evaluate all evidence on measurement properties of the Hip disability and Osteoarthritis Outcome Score - Physical function Shortform (HOOS-PS) and the Knee Injury and Osteoarthritis Outcome Score - Physical function Shortform (KOOS-PS).

Design: This study was conducted according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline for systematic reviews of PROMs. MEDLINE, EMBASE, The Cochrane Library, CINAHL and PsychINFO through February 2019 were searched.

Patient characteristics do not predict the change in physical functioning following arthroplasty measured by the HOOS-PS and KOOS-PS.

Predicting personalized outcome after arthroplasty improves shared decision-making. The aim of this paper was to determine predictors of functional outcome measured by the Hip disability and Osteoarthritis Outcome Score - Physical function Shortform (HOOS-PS) or Knee injury and Osteoarthritis Outcome Score - Physical function Shortform (KOOS-PS) in patients undergoing total hip (n = 79) or total knee arthroplasty (n = 90) respectively. Patients were assessed at baseline and following arthroplasty.
