- Description: The risk of post-traumatic osteoarthritis (PTOA) substantially increases following joint injury. Research efforts should focus on investigating the efficacy of preventative strategies in high quality randomized controlled trials (RCT). The objective of these OARSI RCT recommendations is to inform the design, conduct and analytical approaches to RCTs evaluating the preventative effect of joint injury prevention strategies. Recommendations regarding the design, conduct, and reporting of RCTs evaluating injury prevention interventions were established based on the consensus of nine researchers internationally with expertise in epidemiology, injury prevention and/or osteoarthritis (OA). Input and resultant consensus was established through teleconference, face to face and email correspondence over a 1 year period. Recommendations for injury prevention RCTs include context specific considerations regarding the research question, research design, study participants, randomization, baseline characteristics, intervention, outcome measurement, analysis, implementation, cost evaluation, reporting and future considerations including the impact on development of PTOA. Methodological recommendations for injury prevention RCTs are critical to informing evidence-based practice and policy decisions in health care, public health and the community. Recommendations regarding the interpretation and conduct of injury prevention RCTs will inform the highest level of evidence in the field. These recommendations will facilitate between study comparisons to inform best practice in injury prevention that will have the greatest public health impact.

- Description: Background: Patient-reported outcomes (PROs) are considered the gold standard when evaluating outcomes in a surgical population. While the psychometric properties of some PROs have been tested, the properties of newer PROs in patients undergoing hip arthroscopic surgery remain somewhat unknown. Purpose: To evaluate the reliability, validity, responsiveness, and interpretability of 5 PROs (Copenhagen Hip and Groin Outcome Score [HAGOS], Hip Disability and Osteoarthritis Outcome Score [HOOS], Hip Outcome Score [HOS], International Hip Outcome Tool [iHOT-33], and Modified Harris Hip Score [MHHS]) in a population undergoing hip arthroscopic surgery and also to provide a recommendation of the best PROs in patients undergoing hip arthroscopic surgery. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Study participants were adults (mean age, 37 ± 11 years) who had undergone hip arthroscopic surgery 12 to 24 months previously and pain-free, healthy age-matched controls (mean age, 35 ± 11 years). Baseline characteristics including age, height, weight, waist girth, physical activity, and occupation were collected for both groups. The hip arthroscopic surgery group completed the 5 PRO questionnaires on 3 occasions, while the healthy control group completed the PRO questionnaires on 1 occasion. The reliability (test-retest reliability [intraclass correlation coefficient, or ICC] and minimal detectable change [MDC]), validity (construct validity, ability to detect a difference between groups, acceptability including floor and ceiling effects), responsiveness, and interpretability (minimal important change [MIC]) of each measure were calculated. Results: The test-retest reliability of PROs was excellent (ICC, 0.91-0.97), with an MDC of<20%. The HOOS, HAGOS, and iHOT- 33 had acceptable content validity. All PROs demonstrated construct validity and were able to detect a difference between the hip arthroscopic surgery and control groups. No measures demonstrated a floor effect; however, the MHHS and subscales relating to activities of daily living of the HOOS, HOS, and HAGOS demonstrated a ceiling effect. The HOOS, iHOT-33, and MHHS demonstrated adequate responsiveness, and the MIC for all measures was<11 points of a possible 100 points. Conclusion: The PROs of the HOOS and iHOT-33 demonstrate psychometric properties that may enable researchers and clinicians to use them with confidence in a population undergoing hip arthroscopic surgery. The psychometric properties of the MHHS, HOS, and some subscales of the HAGOS are reduced, and these PROs may be less valuable in this group. © 2013 The Author(s).

- Description: Background/aim: To recommend Patient-Reported Outcome (PRO) questionnaires to measure hip and groin disability in young-aged to middle-aged adults. Methods: A systematic review was performed in June 2014. The methodological quality of the studies included was determined using the COnsensus-based Standards for the selection of health Measurement INstruments list (COSMIN) together with standardised evaluations of measurement properties of each PRO. Results: Twenty studies were included. Nine different questionnaires for patients with hip disability, and one for hip and groin disability, were identified. Hip And Groin Outcome Score (HAGOS), Hip Outcome Score (HOS), International Hip Outcome Tool-12 (IHOT-12) and IHOT-33 were the most thoroughly investigated PROs and studies including these PROs reported key aspects of the COSMIN checklist. HAGOS and IHOT-12 were based on studies with the least ratings of poor study methodology (23% and 31%, respectively), whereas IHOT-33 and HOS had a somewhat larger distribution (46%). These PROs all contain adequate measurement qualities for content validity (except HOS), test-retest reliability, construct validity, responsiveness and interpretability. No information or poor quality rating on methodological aspects made it impossible to fully evaluate the remaining PROs at present. Conclusions: HAGOS, HOS, IHOT-12 and IHOT-33 can be recommended for assessment of young-aged to middle-aged adults with pain related to the hip joint, undergoing non-surgical treatment or hip arthroscopy. At present, HAGOS is the only PRO also aimed for young-aged to middle-aged adults presenting with groin pain and is recommended for use in this population.
