- BackgroundThere is conflicting evidence regarding the association between cam morphological changes and hip pain, and it remains unclear who with cam morphology will develop hip pain and who will not. This study aimed to investigate the correlation between cam morphology, hip pain, and activity level at a 5-year follow-up in young Alpine and Mogul skiers.MethodAll students (n = 76) at angstrom re Ski National Sports High School were invited and accepted participation in this prospective study at baseline. Magnetic resonance imaging (MRI) of both hips was conducted to evaluate the presence of cam morphology (alpha -angle >= 55 degrees) and its size alongside the reporting of hip pain, type, and frequency of training by the Back and hip questionnaire, at baseline. After 5 years, the skiers were invited to complete a shortened version of the same questionnaire.ResultsA total of 60 skiers (80%) completed the follow-up questionnaire, of which 53 had concomitant MRI data. Cam morphology was present in 25 skiers (47.2%, 39 hips). Hip pain at baseline and at follow-up was reported in 17 (28.3%) and 22 (36.7%) skiers, respectively. No correlations were found between the activity level, the frequency, and the size of cam morphology and hip pain, except for the right hip alpha -angle at 1 o'clock and hip pain in skiers with cam morphology at baseline (r(s) = 0.49; P = 0.03) and at follow-up (r(s) = 0.47; P = 0.04). A total of 73.3% skiers had retired, of which 48% reported this was due to injuries.ConclusionHip pain was not shown to be correlated, or had a low correlation, with activity level and the presence and size of cam morphology in young skiers on a 5-year follow-up. Based on these results, cam morphology or activity level did not affect hip pain to develop during 5 years of follow-up in young skiers. Furthermore, this study highlights that almost 75% of young elite skiers had retired from their elite career with almost 50% reporting that this was due to injuries sustained from skiing.

- The purpose was to investigate pre-operative symptoms and types of sport in competitive athletes undergoing arthroscopic treatment for femoroacetabular impingement syndrome (FAIS), and to compare between genders. Competitive athletes planned for arthroscopic treatment for FAIS were included prospectively in a hip arthroscopy registry. A total of 1548 athletes were identified and 919 were included. Sporting activity and patient-reported outcome measures (PROMs), including HSAS, iHOT-12, and HAGOS, were recorded, pre-operatively. The study comprised 738 male and 181 female athletes (median age 25; interquartile range 20-32 years) who had undergone arthroscopic treatment for FAIS. The most common sports type performed by males were football (48%) and ice hockey (19%) and in females, football (25%) and horseback riding (22%). Females reported a significantly longer duration of symptoms (median 36 vs 24 months) and lower pre-operative scores for the iHOT-12 and all the HAGOS subscales, except for physical activity. In conclusion, horseback riding and football are almost equally common in female athletes, while football is by far the most common in male athletes, who underwent arthroscopic treatment for FAIS. Females had a longer duration of symptoms and a higher degree of self-reported symptoms and dysfunction prior to the hip arthroscopy.

- Purpose: The aim was to investigate the rate of athletes still active at their pre-injury sports level two years after arthroscopic treatment for femoroacetabular impingement syndrome (FAIS), and examine this between different sports and gender, and its correlation to patient-reported outcome measures (PROMs). Method: High-level athletes planned for arthroscopic treatment for FAIS were included prospectively in a Swedish hip arthroscopy registry between 2011 and 2017, and 717 met the inclusion criteria. Self-reported sporting activity was recorded preoperatively. The subjects answered PROMs, including the HSAS, iHOT-12 and HAGOS pre- and postoperatively. Results: A total of 551 athletes (median age 26, interquartile range 20–34 years; 23% women) had completed follow-up PROMs, at mean 23.4 ± 7.2 months postoperatively. In total, 135 (24.5%) were active at their pre-injury level of sports at follow-up (RTSpre). Athletes ≤30 years at time of surgery (n = 366; median age 22 years) had higher rate of RTSpre (31.4%) compared with athletes > 30 years (n = 185; median age 40 years) (10.8%; p < 0.001). All athletes had improvements in iHOT-12 and HAGOS, two years postoperatively (p < 0.001), while RTSpre athletes reported significantly better PROMs, pre- and postoperatively, and had greater improvements two years postoperatively, compared with athletes not active at pre-injury level. Conclusion: Only 25% of all high-level athletes and 31% of athletes ≤30 years were still active at their pre-injury sports level two years after arthroscopic treatment for FAIS. Athletes still active had significantly and clinically greater improvement regarding hip symptoms, function and quality of life, as compared with athletes not active at pre-injury level, two years postoperatively. © 2020, The Author(s).

- Background: Current knowledge of the effect of changes in posture and the way cam morphology of the hip joint may affect hip range of motion (ROM) is limited. Purpose: To determine the effect of changes in pelvic tilt (PT) on hip ROM and with/without the presence of cam. Materials and methods: The hip ROM of 87 subjects (n=61 young elite skiers, n=26 nonathletes) was examined using a goniometer, in three different seated postures (flexed, neutral, and extended). The hips of the subjects were further subgrouped into cam and no-cam morphology, based on the magnetic resonance imaging findings in the hips. Results: There was a significant correlation between the hip ROM and the seated posture in both extended and flexed postures compared with the neutral posture. There was a significant decrease in internal hip rotation when the subjects sat with an extended posture with maximum anterior PT (p<0.0001). There was a significant increase in internal hip rotation when the subjects sat with a flexed posture with maximum posterior PT (p<0.001). External rotation was significantly decreased in an extended posture with maximum anterior PT (p<0.0001), but there was no difference in flexed posture with maximum posterior PT. The hips with cam morphology had reduced internal hip rotation in all three positions, but they responded to the changes in position in a similar manner to hips without cam morphology. Conclusion: Dynamic changes in PT significantly influence hip ROM in young people, independent of cam or no-cam morphology.

- RACOMIP is a population-based, randomized trial of the effectiveness and cost-effectiveness of different interventions aimed at increasing participation in a well-run cervical cancer screening program in western Sweden. In this article, we report results from one intervention, offering non-attendees a high-risk human papillomavirus (HPV) self-test. Comparison was made with standard screening invitation routine or standard routine plus a telephone call. Women (8,800), aged 30-62, were randomly selected among women without a registered Pap smear in the two latest screening rounds. These women were randomized 1:5:5 to one of three arms: 800 were offered a high-risk HPV self-test, 4,000 were randomized to a telephone call (reported previously) and 4,000 constituted a control group (standard screening invitation routine). Results were based on intention to treat analysis and cost-effectiveness was calculated as marginal cost per cancer case prevented. The endpoint was the frequency of testing. The total response rate in the self-testing arm was 24.5%, significantly higher than in the telephone arm (18%, RR 1.36, 95% CI 1.19-1.57) and the control group (10.6%, RR 2.33, 95% CI 2.00-2.71). All nine women who tested positive for high-risk HPV attended for a cervical smear and colposcopy. From the health-care sector perspective, the intervention will most likely lead to no additional cost. Offering a self-test for HPV as an alternative to Pap smears increases participation among long-term non-attendees. Offering various screening options can be a successful method for increasing participation in this group.
