Groin injuries in women's premier league football in Norway: A two-season prospective cohort study describing clinical and imaging characteristics. Scand J Med Sci Sports 2024; 34:e14611. [PMID: 38534061 DOI: 10.1111/sms.14611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 12/13/2023] [Accepted: 03/13/2024] [Indexed: 03/28/2024]
Abstract
OBJECTIVE To describe the prevalence, incidence, and burden of groin injuries in the Norwegian women's premier football league and to describe their clinical and imaging characteristics. METHODS During the 2020 and 2021 seasons, players in the Norwegian women's premier league reported groin injuries weekly, using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems (OSTRC-H2). We calculated weekly prevalence, incidence, and burden of groin injuries. The team physical therapists classified the player-reported injuries based on the Doha classification system. Injuries with more than 3 days' time loss or reported in 2 consecutive weeks were eligible for magnetic resonance imaging (MRI). RESULTS On average, 3.9% (95% CI: 3.4-4.4) of players reported a groin injury at any time; of which 78% caused time loss. The incidence rate was 1.6 injuries/1000 h (95% CI: 1.3-2.0) and their burden was 11 days lost/1000 h. The physical therapists examined 67 of 124 player-reported groin injuries (53%). Adductor-related injury was most common (55%) followed by iliopsoas (15%) and rectus femoris-related (12%). Pubic-related injuries caused most time loss (median: 24 days, IQR: 5-133). In this study, 42 injuries were investigated with MRI; 8 (19%) showed no changes, 6 (14%) an acute musculotendinous lesion, and 32 (76%) a nonacute finding (e.g., central symphyseal disc protrusion, tendinopathies). CONCLUSION The incidence rate and burden of groin injuries were high. Adductor-related injuries were most common, but pubic-related injuries caused most time loss. Most MRI examinations demonstrated nonacute findings.

Abstract
BACKGROUND Controversies remain regarding the diagnosis, imaging, and treatment of acute adductor injuries in athletes. PURPOSE To investigate the diagnostic imaging, treatment, and prevention of acute adductor injuries based on the most recent and relevant scientific evidence. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS The PubMed and Web of Science databases were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify articles studying acute adductor injury in athletes. Inclusion criteria were original publication on acute adductor injury in amateur or professional athletes, level 1 to 4 evidence, mean patient age >15 years, and results presented as return-to-sport, pain, or functional outcomes. Quality assessment was performed with the CONSORT (Consolidated Standards of Reporting Trials) statement or the methodological index for non-randomized studies criteria. Articles were grouped as imaging, treatment, prevention focused, or mixed. RESULTS A total of 30 studies published between 2001 and 2021 were selected, involving 594 male patients with a mean age 26.2 years (range, 16-68 years). The most frequent sports were soccer (62%), basketball (14%), futsal (6%), American football (3%), and ice hockey and handball (2%). Risk factors for acute adductor injury were previous acute groin injury, adductor weakness compared with the uninjured side, any injury in the previous season, and reduced rotational hip range of motion. The frequency of complete adductor muscle tears on magnetic resonance imaging was 21% to 25%. For complete adductor tears, the average time to return to play was 8.9 weeks in patients treated nonoperatively and 14.2 weeks for patients treated surgically. Greater stump retraction was observed in individuals treated surgically. Partial acute adductor tears were treated nonoperatively with physical therapy in all studies in the present systematic review. The average time to return to play was 1 to 6.9 weeks depending on the injury grade. The efficacy of adductor strengthening on preventing acute adductor tears has controversial results in the literature. CONCLUSION Athletes with partial adductor injuries returned to play 1 to 7 weeks after injury with physical therapy treatment. Nonoperative or surgical treatment is an acceptable option for complete adductor longus tendon tear.

Abstract
Adductor-related groin pain is a common problem in sports. Evidence-based management of athletes with adductor strains, adductor ruptures, and long-standing adductor-related groin pain can be approached in a simple yet effective and individualized manner. In most cases, managing adductor-related pain in athletes should be based on specific exercises and loading strategies. In this article, I provide an overview of the different types of adductor injuries, from acute to overuse, including their underlying pathology, functional anatomy, diagnosis, prognosis, mechanisms, and risk factors. This information leads to optimal assessment and management of acute to long-standing adductor-related problems and includes primary, secondary, and tertiary prevention strategies that focus on exercise and load-based strategies. In addition, information on different options and contexts for exercise selection and execution for athletes, athletic trainers, and sports physical therapists in adductor injury rehabilitation is provided.

Abstract
Damage to the fascia can cause significant performance deficits in high-performance sports and recreational exercise and may contribute to the development of musculoskeletal disorders and persistent potential pain. The fascia is widely distributed from head to toe, encompassing muscles, bones, blood vessels, nerves, and internal organs and comprising various layers of different depths, indicating the complexity of its pathogenesis. It is a connective tissue composed of irregularly arranged collagen fibers, distinctly different from the regularly arranged collagen fibers found in tendons, ligaments, or periosteum, and mechanical changes in the fascia (stiffness or tension) can produce changes in its connective tissue that can cause pain. While these mechanical changes induce inflammation associated with mechanical loading, they are also affected by biochemical influences such as aging, sex hormones, and obesity. Therefore, this paper will review the current state of knowledge on the molecular level response to the mechanical properties of the fascia and its response to other physiological challenges, including mechanical changes, innervation, injury, and aging; imaging techniques available to study the fascial system; and therapeutic interventions targeting fascial tissue in sports medicine. This article aims to summarize contemporary views.

Pain provocation tests and clinical entities in male football players with longstanding groin pain are associated with pain intensity and disability. Musculoskelet Sci Pract 2023; 63:102719. [PMID: 36736197 DOI: 10.1016/j.msksp.2023.102719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 11/20/2022] [Accepted: 01/05/2023] [Indexed: 01/12/2023]
Abstract
BACKGROUND Clinical examination of male football players with longstanding groin pain can be considered difficult. Pain provocation tests are used to examine and classify longstanding groin pain into clinical entities as adductor-, iliopsoas-, inguinal-, and pubic-related. It is unknown if pain provocation tests and clinical entities are associated with pain intensity and disability. OBJECTIVES To investigate if the number of positive pain provocation tests and clinical entities are associated with pain intensity and disability, measured by the Copenhagen 5-Second Squeeze Test (5SST) and the Copenhagen Hip and Groin Outcome Score (HAGOS), respectively. DESIGN Cross-sectional. METHOD Forty male football players (age: mean 24 years [SD: 3.2]; height: mean 182 cm [SD: 5.7]; weight: mean 78 Kg [SD: 6.6]) with longstanding groin pain for a median of 8.5 months (IQR: 4-36) were included. The players underwent a bilateral groin examination with 33 pain provocation tests and were classified with clinical entities (0-7) based on the test findings. RESULTS The number of positive pain provocation tests (median 10, range 2-23) correlated with pain intensity (5SST: rs = 0.70 [95% CI: 0.50, 0.83]) and disability (HAGOS subscales Sport: rs =-0.62 [95% CI: -0.81, -0.36], Pain: rs = -0.38 [95% CI: -0.69, -0.06], Symptoms: rs = 0.52 [95% CI: -0.73, -0.24], ADL: rs = -0.48 [95% CI: -0.71, -0.18]). The number of clinical entities (median 3, range: 1-7) showed similar but weaker correlations to pain intensity and disability. CONCLUSIONS In male football players with longstanding groin pain, the number of positive pain provocation tests and clinical entities shows weak to strong correlations with pain intensity and disability. Consequently, when pain intensity and disability are severe, a higher number of pain provocation tests may be positive, and more clinical entities may be present.

Abstract
Objectives To evaluate the interexaminer reliability of abdominal palpation and resistance tests in athletes with longstanding groin pain, and to identify the prevalence of positive clinical tests in athletes classified with inguinal-related groin pain. Methods Male athletes (18-40 years) with longstanding groin pain were prospectively recruited between March 2019 and October 2020 at a sports medicine hospital. Two examiners performed history taking and standardised clinical examination (including abdominal palpation, scrotal invagination and abdominal resistance tests) blinded to each other's findings. Interexaminer reliability was calculated using Cohen's Kappa statistic (κ). Examiners classified groin pain using the Doha agreement meeting terminology. A differentiation was made between 'defined inguinal-related groin pain' (according to recommended definition criteria) and 'likely inguinal-related groin pain' (expert-based application of the Doha agreement classification when not all recommended criteria were present). Results Overall, 44 athletes were included (61 symptomatic sides). Interexaminer reliability of inguinal palpation pain provocation tests varied from fair to moderate (κ=0.35-0.49). Reliability of posterior wall structure palpation (firm/soft) was slight (κ=0.01), and posterior wall bulging (yes/no) fair (κ=0.29). Reliability for abdominal resistance tests varied from fair to substantial (κ=0.35-0.72). In athletes classified with defined inguinal-related groin pain, recognisable injury pain on palpation during scrotal invagination when athletes performed a Valsalva manoeuvre was the most prevalent positive palpation test (79%). Abdominal resistance tests were positive in 21%-49% of these cases. Conclusion The interexaminer reliability for clinical examination tests used to classify inguinal-related groin pain in athletes varies from slight to substantial. There is no single perfect clinical examination test. Trial registration number NCT03842826.

Abstract
BACKGROUND Complete avulsions of the adductor longus tendon are serious injuries, yet we have few data to inform clinical decisions on management. Previous studies are limited by a lack of detailed follow-up. PURPOSE To describe detailed clinical and imaging measures 1 year after complete proximal adductor longus avulsion injuries in athletes who received exercise-based treatment. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 16 adult male competitive athletes were included in this study <7 days after an acute adductor longus tendon avulsion injury. All athletes were advised to complete a supervised standardized criterion-based rehabilitation protocol. Standardized clinical examination, a modified Copenhagen Hip and Groin Outcome Score (HAGOS), the Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC-O), and detailed magnetic resonance imaging (MRI) assessment were performed after inclusion, on the day of completion of the treatment protocol (return to sport), and at 1-year follow-up after injury. RESULTS One player was lost to follow-up. Median return-to-sport time was 69 days (interquartile range [IQR], 62-84). One player had an early reinjury and performed an additional rehabilitation period. One-year follow-up was completed a median from 405 days (IQR, 372-540) after injury. The median HAGOS score was 100 for all subscales (IQRs from 85-100 to 100-100), and the median OSTRC-O score was 0 (IQR, 0-0). The median range of motion symmetry was 100% (IQR, 97%-130%) for the bent-knee fall-out test and 102% (IQR, 99%-105%) for the side-lying abduction test. Side-lying eccentric adduction strength symmetry was 92% ± 13% (mean ± SD), and median supine eccentric adduction strength symmetry was 93% (IQR, 89%-105%). MRI results at 1-year follow-up showed that from the original complete discontinuity in all cases, 10 athletes (71%) had partial tendon continuity, and 4 (29%) had complete tendon continuity. CONCLUSION Nonsurgically treated athletes with a complete acute adductor longus avulsion returned to sport in 2 to 3 months. At the 1-year follow-up after injury, athletes had high self-reported function, no performance limitations, normal adductor strength and range of motion, and signs of partial or full tendon continuity as shown on MRI. This indicates that the primary treatment for athletes with acute adductor longus tendon avulsions should be nonsurgical as the time to return to sport is short, there are good long-term results, and there is no risk of surgical complications.

Associations between clinical findings and MRI injury extent in male athletes with acute adductor injuries - A cross-sectional study. J Sci Med Sport 2020; 24:454-462. [PMID: 33334688 DOI: 10.1016/j.jsams.2020.11.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Revised: 11/02/2020] [Accepted: 11/04/2020] [Indexed: 12/26/2022]
Abstract
OBJECTIVES To investigate the association between clinical assessment and MRI measures of oedema and MRI grading in male athletes with acute adductor injuries. DESIGN Cross-sectional study. METHODS We included 81 consecutive athletes with acute adductor injuries. All athletes received a standardized clinical assessment and magnetic resonance imaging (MRI), blinded to clinical information. We analysed correlations between extent of palpation pain and extent of MRI oedema for the adductor longus. We compared the clinical assessment to MRI adductor injury grading (0-3) using ordinal regression. We analysed positive and negative predictive values (PPV/NPV) of a complete adductor longus avulsion. RESULTS Proximal-distal length of adductor longus palpation pain had fair correlation with MRI proximal-distal oedema length oedema (r=0.309, p=0.022). Cross-sectional surface area of palpation pain had poor correlation with corresponding cross-sectional MRI oedema area (r=0.173, p=0.208). The symptoms subscale of the Copenhagen Hip And Groin Outcome Score (HAGOS) for the period since injury (log odds ratio=0.97, p=0.021) and passive adductor stretch pain (log odds ratio=0.35, p=0.046) were associated with MRI injury grading. If there was a palpable defect, MRI always showed a complete avulsion (PPV=100%). Several tests had high negative predictive values: passive adductor stretch (100%), palpation pain at the adductor longus insertion (98%), and the FABER test (98%). CONCLUSIONS The extent of palpation pain does not indicate the extent of MRI oedema in acute adductor longus injuries. A worse modified HAGOS symptoms subscale score and passive adductor stretch pain indicate a higher MRI adductor injury grade. Clinical examination tests have high ability to detect or rule out a complete adductor longus avulsion on MRI.

Abstract
This statement summarises and appraises the evidence on diagnosis, prevention and treatment of the most common lower extremity muscle injuries in sport. We systematically searched electronic databases, and included studies based on the highest available evidence. Subsequently, we evaluated the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation framework, grading the quality of evidence from high to very low. Most clinical tests showed very low to low diagnostic effectiveness. For hamstring injury prevention, programmes that included the Nordic hamstring exercise resulted in a hamstring injury risk reduction when compared with usual care (medium to large effect size; moderate to high quality of evidence). For prevention of groin injuries, both the FIFA 11+programme and the Copenhagen adductor strengthening programme resulted in a groin injury risk reduction compared with usual care (medium effect size; low to moderate quality of evidence). For the treatment of hamstring injuries, lengthening hamstring exercises showed the fastest return to play with a lower reinjury rate compared with conventional hamstring exercises (large effect size; very low to low quality of evidence). Platelet-rich plasma had no effect on time to return-to-play and reinjury risk (trivial effect size; moderate quality of evidence) after a hamstring injury compared with placebo or rehabilitation. At this point, most outcomes for diagnosis, prevention and treatment were graded as very low to moderate quality of evidence, indicating that further high-quality research is likely to have an important impact on the confidence in the effect estimates.

BACKGROUND Time to return-to-sport (RTS) after acute adductor injuries varies among athletes, yet we know little about which factors determine this variance. PURPOSE To investigate the association between initial clinical and imaging examination findings and time to RTS in male athletes with acute adductor injuries. STUDY DESIGN Cohort study (Prognosis); Level of evidence, 2. METHODS Male adult athletes with an acute adductor injury were included within 7 days of injury. Standardized patient history and clinical and magnetic resonance imaging (MRI) examinations were conducted for all athletes. Athletes performed a supervised standardized criteria-based exercise treatment program. Three RTS milestones were defined: (1) clinically pain-free, (2) completed controlled sports training, and (3) first full team training. Univariate and multiple regression analyses were performed to determine the association between the specific candidate variables of the initial examinations and the RTS milestones. RESULTS We included 81 male adult athletes. The median duration for the 3 RTS milestones were 15 days (interquartile range, 12-28 days), 24 days (16-32 days), and 22 days (15-31 days), respectively. Clinical examination including patient history was able to explain 63%, 74%, and 68% of the variance in time to RTS. The strongest predictors for longer time to RTS were pain on palpation of the proximal adductor longus insertion or a palpable defect. The addition of MRI increased the explained variance with 7%, 0%, and 7%. The strongest MRI predictor was injury at the bone-tendon junction. Post hoc multiple regression analyses of players without the 2 most important clinical findings were able to explain 24% to 31% of the variance, with no added value of the MRI findings. CONCLUSION The strongest predictors of a longer time to RTS after acute adductor injury were palpation pain at the proximal adductor longus insertion, a palpable defect, and/or an injury at the bone-tendon junction on MRI. For athletes without any of these findings, even extensive clinical and MRI examination does not assist considerably in providing a more precise estimate of time to RTS.

[PMID: 32064292 PMCID: PMC6990618 DOI: 10.1177/2325967119897247] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Accepted: 11/24/2019] [Indexed: 11/17/2022] Open
Abstract
Background: Despite being one of the most common sports injuries, there are no criteria-based rehabilitation programs published for acute adductor injuries. Purpose: To evaluate return-to-sport (RTS) outcomes and reinjuries after criteria-based rehabilitation for athletes with acute adductor injuries. Study Design: Cohort study; Level of evidence, 2. Methods: Male adult athletes with an acute adductor injury underwent a supervised, standardized criteria-based exercise rehabilitation program. Magnetic resonance imaging (MRI) was used to grade the injury extent from 0 (negative finding) to 3 (complete tear/avulsion). There were 3 milestones used to evaluate the RTS continuum: (1) clinically pain-free, (2) completion of controlled sports training, and (3) return to full team training. Subsequent injuries were registered within the first year. Results: We included 81 athletes with an acute adductor injury (MRI grade 0: n = 14; grade 1: n = 20; grade 2: n = 30; grade 3: n = 17). Of these, 61 (75%) athletes achieved RTS milestone 1, 50 (62%) achieved RTS milestone 2, and 75 (93%) achieved RTS milestone 3. There were no statistical differences in the RTS duration between MRI grade 0, 1, and 2 at any RTS milestone; thus, these were grouped together as grade 0-2. The median time (interquartile range [IQR]) for athletes with grade 0-2 injuries to become clinically pain-free was 13 days (IQR, 11-21 days), to complete controlled sports training was 17 days (IQR, 15-27 days), and to return to full team training was 18 days (IQR, 14-27 days). For athletes with a grade 3 injury, median times were 55 days (IQR, 31-75 days), 68 days (IQR, 51-84 days), and 78 days (IQR, 68-98 days), respectively. The overall 1-year reinjury rate was 8%. Athletes who achieved RTS milestone 1 had a statistically significantly lower reinjury rate than athletes who did not (5% vs 21%, respectively; ϕ = –0.233; P = .048). Athletes who achieved RTS milestone 2 had a nonstatistically significantly lower reinjury rate than athletes who did not (6% vs 13%, respectively; ϕ = –0.107; P = .366). Conclusion: We analyzed the results of a criteria-based rehabilitation protocol for athletes with acute adductor injuries. Athletes with an MRI grade 0-2 adductor injury were clinically pain-free after approximately 2 weeks and returned to full team training after approximately 3 weeks. Most athletes with an MRI grade 3 adductor injury were pain-free and returned to full team training within 3 months. Meeting the clinically pain-free criteria resulted in fewer reinjuries compared with not meeting the criteria.

Abstract
Musculoskeletal conditions, such as hip pain are leading causes of pain and disability. Hip pain is the second most common cause of lower limb musculoskeletal pain, and is commonly seen in active individuals. Hip and groin pain may have intra-articular and extra-articular causes. Femoroacetabular impingement (FAI) syndrome and the associated pathologies are common intra-articular causes of hip and groin pain in active individuals. There are also a number of extra-articular causes of pain, which include musculotendinous conditions, extra-articular impingements and the clinical entities of groin pain described in the Doha agreement. This chapter will describe these, with a detailed focus on FAI syndrome. Specifically, it addresses: 1. What is and what causes FAI syndrome; 2. How do I diagnose FAI syndrome; and 3. What is the evidence-based approach to managing FAI syndrome?

Abstract
OBJECTIVE To determine the diagnostic reliability of magnetic resonance imaging (MRI) sequences in chronic groin pain (CGP) compared to surgery and try to propose a suitable MRI protocol. MATERIALS AND METHODS Forty-three consecutive patients with resistant clinical CGP underwent a pre-surgical pelvis MRI. Eight MRI sequences were acquired: axial fast spin-echo T1-weighted (FSE T1), coronal FSE T1, axial-oblique (in symphysis plane) proton density weighted with fat saturation (PDFS), coronal PDFS, sagittal PDFS, axial FSE T1 with fat saturation and gadolinium enhancement (FSGE), coronal FSE T1 FSGE and axial FSE T1 with Valsalva maneuver (VM). These sequences were reviewed for pubic symphysis assessment, adductor longus (AL) tendon and abdominal wall (AW) injuries. The same surgeon operated on all of these patients (26 AL and 49 AW). Sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative prospective value (NPV) and accuracy of each sequence and combinations for AL or AW injuries were calculated in comparison to surgical findings. RESULTS One hundred ninety-two sequences were obtained. Coronal T1 FSGE and axial T1 VM proved to be the most reliable sequences (accuracy: 91.67% in AL and 83.33% in AW). The best sequence combination was coronal T1, axial PDFS, sagittal PDFS and axial T1 VM (accuracy: 77.78%; Se: 100.00%, Sp: 69.23%, PPV: 55.56%, NPV: 100.00%). CONCLUSION MRI has 77.78% accuracy, 100.00% sensitivity, 69.23% specificity, 55.56% PPV and 100.00% NPV in evaluating CGP, with coronal T1-axial PDFS-sagittal PDFS-axial T1 VM as the optimal protocol in terms of diagnostic performance within a reasonable scan time. Diagnostic performance of MRI was examined in the evaluation of CGP using surgery as reference standard.

Abstract
Synopsis Groin pain is common in athletes who participate in multidirectional sports and has traditionally been considered a difficult problem to understand, diagnose, and manage. This may be due to sparse historical focus on this complex region in sports medicine. Until recently, there has been little agreement regarding terminology, definitions, and classification of groin pain in athletes. This has made clear communication between clinicians difficult, and the results of research difficult to interpret and implement into practice. However, during the past decade, the field has evolved rapidly, and an evidence-based understanding is now emerging. This clinical commentary discusses the clinical examination (subjective history, screening, physical examination); imaging; testing of impairments, function, and performance; and management of athletes with groin pain in an evidence-based framework.

Abstract
Background: Although iliopsoas disorder is one of the most frequent causes of groin pain in athletes, little is known about its prevalence and clinical impact. Methods: We retrospectively reviewed the cases of 638 consecutive athletes who had groin pain. Each athlete was assessed with magnetic resonance imaging (MRI). First, we identified the prevalence of changes in signal intensity in the iliopsoas. Then we classified the changes in signal intensity in the iliopsoas, as visualized on short tau inversion recovery MRI, into 2 types: the muscle-strain type (characterized by a massive high-signal area in the muscle belly, with a clear border) and the peritendinitis type (characterized by a long and thin high-signal area extending proximally along the iliopsoas tendon from the lesser trochanter, without a clear border). Finally, we compared the time to return to play for the athletes who had these signal intensity changes. Results: Changes in signal intensity in the iliopsoas were detected in 134 (21.0%) of the 638 athletes. According to our MRI classification, 66 athletes had peritendinitis changes and 68 had muscle-strain changes. The time from the onset of groin pain to return to play was significantly shorter for the patients with muscle-strain changes on MRI than for those with peritendinitis changes (8.6 ± 8.3 versus 20.1 ± 13.9 weeks, respectively; p < 0.0001). Conclusions: Changes in MRI signal intensity in the iliopsoas were observed in 21.0% of 638 athletes who had groin pain. Distinguishing between muscle-strain changes and peritendinitis changes could help to determine the time to return to play.

Abstract
Acute adductor injuries account for the majority of acute groin injuries; however, little is known about specific injury characteristics, which could be important for the understanding of etiology and management of these injuries. The study aim was to describe acute adductor injuries in athletes using magnetic resonance imaging (MRI). Male athletes with acute groin pain and an MRI confirmed acute adductor muscle injury were prospectively included. MRI was performed within 7 days of injury using a standardized protocol and a reliable assessment approach. 156 athletes presented with acute groin pain of which 71 athletes were included, median age 27 years (range 18-37). There were 46 isolated muscle injuries and 25 athletes with multiple adductor injuries. In total, 111 acute adductor muscle injuries were recorded; 62 adductor longus, 18 adductor brevis, 17 pectineus, 9 obturator externus, 4 gracilis, and 1 adductor magnus injury. Adductor longus injuries occurred at three main injury locations; proximal insertion (26%), intramuscular musculo-tendinous junction (MTJ) of the proximal tendon (26%) and the MTJ of the distal tendon (37%). Intramuscular tendon injury was seen in one case. At the proximal insertion, 12 of 16 injuries were complete avulsions. This study shows that acute adductor injuries generally occur in isolation from other muscle groups. Adductor longus is the most frequently injured muscle in isolation and in combination with other adductor muscle injuries. Three characteristic adductor longus injury locations were observed on MRI, with avulsion injuries accounting for three-quarters of injuries at the proximal insertion, and intramuscular tendon injury was uncommon.
