The outcome of arthroscopic repair of acetabular labral tears using the iHOT-33.

BACKGROUND: The purpose of this study was to determine patient reported outcome measures (PROMS) after arthroscopic repair of an isolated labral tear using the validated International Hip Outcome Tool (iHOT-33). The iHOT-33 specifically measures (1) symptoms and functional limitations, (2) sport and recreation limitations, (3) job related concerns and social and (4) emotional and lifestyle concerns. METHODS: A retrospective review was performed on 45 procedures in 43 patients between September 2012 and September 2015. Two patients had bilateral isolated labral tears. Patients were excluded if they were younger than 18 years, had prior ipsilateral hip surgery and had radiological or arthroscopic evidence of femoroacetabular impingement (FAI), hip dysplasia or other bony dysmorphism. RESULTS: Of the 43 patients undergoing arthroscopy there were 29 right and 16 left hips repaired. There were 34 females and 9 males. The mean age at surgery was 37.4 years (range 19-63 years) with a mean follow up of 1.7 years (range 1.0-2.6 years). At follow up the mean total iHOT-33 score improved from 34.1 to 67.3 (p < 0.02). The mean improvement was 33.2 (p = < 0.02). Significant improvements were described in all 4 iHOT-33 sub sections. CONCLUSION: The study showed statistically significant favourable outcomes in selected patients with short follow-up for patients that underwent hip arthroscopy for an isolated labral tear using the validated iHOT-33. LEVEL OF EVIDENCE: IV, retrospective non-randomised study.

Prevalence and Trends of Patient-Reported Outcome Measures Used in Hip Arthroscopy.

The aim of this review was to determine the prevalence of patient-reported outcome measures concerning outcomes of arthroscopic hip surgery. The PubMed database was comprehensively reviewed in March 2016 using the key terms "hip" and "arthroscopy." A total of 192 eligible studies were identified. The most commonly used patient-reported outcome measures were the modified Harris Hip score (61%) and the Non-arthritic Hip Score (27%). Seventy-one percent of total patient-reported outcome measures articles were published between 2011 and 2015. The modified Harris Hip score, Nonarthritic Hip Score, and Hip Outcome Score remain the most commonly used patient-reported outcome measures in studies concerning outcomes of hip arthroscopy, and this has increased in the past 5 years.

PROMsBase: Web-based repository portal for patient-reported outcome measures in orthopaedics.

Patient-reported outcome measures lead to better communication and decision-making between clinicians and patients. Applying a web-based repository system for data collection was previously suggested, but such system is not available. This article introduces the development and implementation of a new web-based application, PROMsBase, in orthopaedics clinical practice. PROMsBase was developed using a web interface, allows access using both desktop and mobile devices. Between 2013 and 2016, a total of 3192 pre-surgery questionnaires were collected. In total, 238 patients completed their post-surgery questionnaire online from home. PROMsBase was well embedded into routine practice without disrupting clinical workflow and overloading clinicians' and researchers' workload. Tablets were not more useful and only 37 per cent of the patients completed the questionnaire online. PROMsBase provided a platform to easily collect and store data in clinical practice. If properly integrated, this could promote better care and communication between providers and patients.

Identification of a Patient Acceptable Symptomatic State Score for the International Hip Outcome Tool in People Undergoing Hip Arthroscopy.

PURPOSE: To determine a Patient Acceptable Symptomatic State (PASS) score for the 33-item International Hip Outcome Tool (iHOT-33) in people undergoing hip arthroscopy for primary diagnoses of femoroacetabular impingement syndrome, acetabular labral tears, and/or ligamentum teres pathology. METHODS: Consecutive participants underwent hip arthroscopy by a single surgeon between August 2011 and May 2016. Participants were included if they were between ages 18 and 60 years and underwent hip arthroscopy for femoroacetabular impingement syndrome, acetabular labral tears, or ligamentum teres pathology. Participants were excluded if they did not speak sufficient English to complete the iHOT-33, had evidence of hip dysplasia, had less than 2 mm of joint space on anteroposterior radiograph, or underwent subsequent total hip replacement surgery. Participants completed the iHOT-33 preoperatively and at a minimum of 1 to a maximum of 5 years postoperatively. Participants were also asked to answer yes or no to the external anchor question of "Taking into account all the activities you do during your daily life, your level of pain and also your functional impairment, are you satisfied with your current state following your surgery?" A receiver operating characteristic (ROC) curve was used to identify the PASS score. Multiple logistic regression was performed to determine if patient factors, primary preoperative diagnosis, or intraoperative findings predicted achievement of the PASS score. RESULTS: A total of 117 participants undergoing hip arthroscopy were included: 72 women (61.1%) and 45 men (38.5%) with mean age of 36.81 years (18-59). Forty-two (35.9%) had cam morphology, 18 (15.4%) had pincer morphology, 78 (67.2%) had labral tears, and 97 (82.9%) had ligamentum teres tears. Mean time to final follow-up was 2.25 years (range, 1-5). The PASS score at a mean of 2.25 years postoperatively was 58 as determined by the cutoff threshold on the ROC curve with the lowest difference between sensitivity and specificity (area under the ROC curve 0.88; P < .01; 95% confidence interval [CI], 0.81-0.95). No factors were predictors of achievement of the PASS score in this study (P > .05), including age (odds ratio [OR], 0.71; 95% CI, 0.32-1.56), sex (OR, 1.02; 95%, CI 0.98-1.06), preoperative iHOT-33 score (OR, 1.002; 95% CI, 0.98-1.03), primary preoperative diagnosis (OR, 0.86; 95% CI, 0.53-1.40), cam morphology (OR, 1.19; 95% CI, 0.54-2.64), Pincer morphology (OR, 0.50; 95%, CI 0.18-1.38), acetabular labral tears (OR, 1.93; 95% CI, 0.88-4.26), Outerbridge grade 3-4 chondral damage (OR, 0.97; 95% CI, 0.42-2.25), and ligamentum teres pathology (OR, 0.95; 95% CI, 0.35-2.61). CONCLUSIONS: This study reports a PASS score of 58 for the iHOT-33 at 2 years following hip arthroscopy. The PASS score will assist in assessing response to hip arthroscopy in research and clinical settings. LEVEL OF EVIDENCE: Level II, retrospective prognostic study.

Outcomes of arthroscopic debridement of isolated Ligamentum Teres tears using the iHOT-33.

BACKGROUND: Tears of the Ligamentum Teres are a common cause of groin pain. Tears of the ligament frequently co-exist alongside other bony or labral intra-articular hip lesions, which are also treated at the time of arthroscopy. For this reason, it is often difficult to assess the effect that debridement alone has on improving patient pain and function. This study aims to assess the short-term outcomes of arthroscopic debridement of isolated Ligamentum Teres tears using a validated patient-reported outcome score - the International Hip Outcome Tool (iHOT-33). METHODS: A retrospective review was performed of 35 patients (37 hips) who had an isolated Ligamentum Teres tear treated with arthroscopic radiofrequency debridement between September 2012 and September 2015. Patients with concomitant intra-articular hip pathology (femoroacetabular impingement, labral lesions, hip dysplasia) were excluded from the study. All patients completed the iHOT-33 questionnaire pre-operatively and post-operatively. The mean age was 37.7 years (range 16-67 years) and patients were followed up for a mean period of 17.7 months (range 6-42 months). Thirty-one patients were female and 4 were male. RESULTS: Thirty-seven isolated partial tears were managed with arthroscopic radiofrequency debridement. At follow up, the mean iHOT-33 score improved from 26.9 pre-operatively to 48.0 post-operatively, representing a mean improvement of 21.1 (p < 0.001). The minimum clinically important difference of the iHOT-33 is 6.1 points. Significant improvements were noted in all four sub-sections of the iHOT-33. CONCLUSION: Arthroscopic radiofrequency debridement of isolated Ligamentum Teres tears provides short-term benefit in the majority of patients, including significant improvement in sporting function.
