Background: Adductor dysfunction is a condition that can cause groin pain in competitive athletes, but the source of the pain has not been established and no specific interventions have been evaluated. We previously defined a magnetic resonance imaging protocol to visualize adductor enthesopathy. The aim of this study was to elucidate, in the context of adductor-related groin pain in the competitive athlete, the role of the adductor enthesis (origin), the relevance of adductor enthesopathy diagnosed with magnetic resonance imaging, and the efficacy of entheseal pubic cleft injections of local anesthetic and steroids.Methods: We reviewed the findings in a consecutive series of twenty-four competitive athletes who had presented to our sports medicine clinic with groin pain secondary to adductor longus dysfunction. Magnetic resonance imaging was performed to assess the adductor longus origin for the presence or absence of enthesopathy. Seven patients (Group 1) had no evidence of enthesopathy on magnetic resonance imaging, and seventeen patients (Group 2) had enthesopathy confirmed on magnetic resonance imaging. All patients were treated with a single pubic cleft injection of local anesthetic and steroid into the adductor enthesis. At one year after this treatment, the patients were assessed for recurrence of symptoms.Results: On clinical reassessment five minutes after the injection, all twenty-four athletes reported resolution of the groin pain. At one year, none of the seven patients in Group 1 had experienced a recurrence. Sixteen of the seventeen patients in Group 2 had a recurrence of the symptoms (p < 0.001) at a mean of five weeks (range, one to sixteen weeks) after the injection.Conclusions: A single entheseal pubic cleft injection can be expected to afford at least one year of relief of adductor-related groin pain in a competitive athlete with normal findings on a magnetic resonance imaging scan; however, it should be employed only as a diagnostic test or short-term treatment for a competitive athlete with evidence of enthesopathy on magnetic resonance imaging.

Purpose: Hamstring muscle strain injury is very common in sports involving high-speed running. Hamstring muscles originate from the ischial tuberosity and thus pelvic position may influence hamstring strain during different sports movements like sprinting, but this has only been evaluated by indirect methods. This study tested the hypothesis that a change in anterior pelvic tilt causes elongation of the overall hamstring complex and disproportionately elongates proximal relative to distal muscle regions., Methods: Seven fresh-frozen specimens (full lower limb with pelvis and lumbar spine) were used for this in vitro study. Specimens were dissected to enable visualization of the hamstring muscles and then fixed into a custom-made testing bench that allowed controlled movement of the pelvis over a fixed femur and tibia. Nine markers were inserted into the hamstring muscles to allow intra- and intermuscle difference measurements. Then, six different anterior pelvic angles were used to measure the difference in hamstring muscle lengthening through a three-dimensional reconstruction system based on stereoscopic machine vision technology., Results: An increase in anterior pelvic tilt produced a significant non-uniform increase in tissue elongation in all regions of the three hamstring muscles (semitendinosus, semimembranosus [SMB] and biceps femoris long head), which was greater in the proximal (>1 cm every 5°) compared to the distal region (≈0.4 cm every 5°). At the proximal hamstring region, SMB showed significantly greater length changes compared to conjoint tendons with nonstatistically significant elongation differences between muscles at the distal region., Conclusion: Considering the results of the study, the pelvis segment will likely play a fundamental role as a strain regulator of hamstring muscles. These results will have an impact on injury rehabilitation and prevention processes of hamstring injuries, as well as optimize future musculoskeletal models and avoid potential underestimation of the hamstring muscle-tendon complex lengthening during high-speed running., Level of Evidence: N/A., (© 2024 European Society of Sports Traumatology, Knee Surgery and Arthroscopy.)

Background: The postoperative management of femoroacetabular impingement (FAI) is variable with favourable surgical outcomes. Yet there is no evidence on the efficacy of hydrotherapy in athletes undergoing hip arthroscopy for FAI. The purpose of this study was to evaluate the role and the impact of hydrotherapy on return to sports following hip arthroscopy for symptomatic FAI., Methods: 2 cohorts of mixed level of athletes from various sports: a hydrotherapy group that followed land-based exercises in combination with hydrotherapy exercises and a control group that followed solely the same land-based exercises. Pre- and postoperative pain and hip-specific outcome scores were completed, and patient satisfaction was rated., Results: A total of 88 hip arthroscopies were included with a minimum of 2 years follow-up; the hydrotherapy group comprised of 36 hips and the control group, 52 hips. There was a significant improvement in time to return to previous performance (HR 1.91, 95% CI, 1.21-3.01; p  = 0.005) in the hydrotherapy group compared with the control. The hip-specific scores and patient satisfaction were considerably improved in the hydrotherapy group., Conclusions: The analysis of our data indicates that the incorporation of hydrotherapy into postoperative rehabilitation for hip arthroscopy for FAI accelerates the return of athletes to their pre-injury performance, since recovery time decreased significantly., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: The purpose of the study is to review the MRI findings in a cohort of athletes who sustained acute traumatic avulsions of the adductor longus fibrocartilaginous entheses, and to investigate related injuries namely the pyramidalis-anterior pubic ligament-adductor longus complex (PLAC). Associated muscle and soft tissue injuries were also assessed., Methods: The MRIs were reviewed for a partial or complete avulsion of the adductor longus fibrocartilage, as well as continuity or separation of the adductor longus from the pyramidalis. The presence of a concurrent partial pectineus tear was noted. Demographic data were analysed. Linear and logistic regression was used to examine associations between injuries., Results: The mean age was 32.5 (SD 10.9). The pyramidalis was absent in 3 of 145 patients. 85 of 145 athletes were professional and 52 competed in the football Premier League. 132 had complete avulsions and 13 partial. The adductor longus was in continuity with pyramidalis in 55 athletes, partially separated in seven and completely in 81 athletes. 48 athletes with a PLAC injury had a partial pectineus avulsion. Six types of PLAC injuries patterns were identified. Associated rectus abdominis injuries were rare and only occurred in five patients (3.5%)., Conclusion: The proximal adductor longus forms part of the PLAC and is rarely an isolated injury. The term PLAC injury is more appropriate term. MRI imaging should assess all the anatomical components of the PLAC post-injury, allowing recognition of the different patterns of injury., Level of Evidence: Level III., (© 2020. The Author(s).)

Groin pain is a common problem in athletes. The diagnosis can be difficult because of the complexity of the groin anatomy, the numerous clinical entities presenting with similar symptoms, the concurrence of those entities and the confusing terminology. Thus, a dilemma in diagnosis may arise leading to long-standing symptoms, disabling groin pain, mismanagement and therefore to poor treatment. Hereby, we present such a case of a recreational athlete complaining for excruciate pubic pain after being misdiagnosed and subsequently mistreated affecting her quality of life. We report on a new interesting finding, the focal osteopenia over the pubic parasymphyseal bone, together with administration of bisphosphonates for first time, as a treatment, for this condition in this body area. Our purpose is to shed light on the pathomechanism of groin pain labelled as osteitis pubis. We also outline the importance of thorough history and physical examination combined with appropriate advanced imaging., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Introduction: Pelvic apophyseal avulsion can limit young athletes' performance for months and may result in permanent disability. Nonoperative treatment is most commonly preferred, while surgical management with reduction and fixation is reserved for selected cases. Our aim was to evaluate outcomes of operative management of pelvic apophyseal avulsions in a series of adolescents and young adult athletes., Materials and Methods: Operative room registries and medical records were reviewed to identify patients who received surgical treatment for pelvic apophyseal avulsions who were younger than 24 years and with a minimum of 12 month follow-up., Results: Thirty-two patients (16.8 years ± 2.6) were identified. The most common avulsion sites were anterior inferior iliac spine (34.4%, N = 11) and ischial tuberosity (34.4%, N = 11). Other avulsions were five cases (15.6%) of the pubic apophysis, four cases (12.5%) of the anterior superior iliac spine apophysis and one case of the iliac crest apophysis. Seventeen cases (53.1%) underwent surgery early, i.e., during the first 3 months after the acute injury. Twenty-two cases (68.8%) involved reduction with internal fixation, and six cases (18.8%) involved resection of the fragment. Twenty-six athletes (81.3%, N = 26) reported good outcomes and were able to return to preinjury sports level. Six patients (18.8%) had moderate outcome and reported activity limitations during high-level sports. Large displacement (> 20 mm) or delayed (> 3 months) surgery was not associated with inferior outcomes (P = 0.690 and P = 0.392, respectively). Injury side (P = 0.61) or gender (P = 0.345) did not affect outcomes., Conclusions: Operative management of pelvic apophyseal avulsion results in return to the preinjury sports level in more than 80% of the cases. However, while both acute surgery for large displacement and delayed intervention for failed nonoperative treatment are generally successful in improving sports function in these cases, comparative studies are required to refine criteria for surgery., Level of Evidence: Case series, IV.

Purpose: Adductor longus injuries are complex. The conflict between views in the recent literature and various nineteenth-century anatomy books regarding symphyseal and perisymphyseal anatomy can lead to difficulties in MRI interpretation and treatment decisions. The aim of the study is to systematically investigate the pyramidalis muscle and its anatomical connections with adductor longus and rectus abdominis, to elucidate injury patterns occurring with adductor avulsions., Methods: A layered dissection of the soft tissues of the anterior symphyseal area was performed on seven fresh-frozen male cadavers. The dimensions of the pyramidalis muscle were measured and anatomical connections with adductor longus, rectus abdominis and aponeuroses examined., Results: The pyramidalis is the only abdominal muscle anterior to the pubic bone and was found bilaterally in all specimens. It arises from the pubic crest and anterior pubic ligament and attaches to the linea alba on the medial border. The proximal adductor longus attaches to the pubic crest and anterior pubic ligament. The anterior pubic ligament is also a fascial anchor point connecting the lower anterior abdominal aponeurosis and fascia lata. The rectus abdominis, however, is not attached to the adductor longus; its lateral tendon attaches to the cranial border of the pubis; and its slender internal tendon attaches inferiorly to the symphysis with fascia lata and gracilis., Conclusion: The study demonstrates a strong direct connection between the pyramidalis muscle and adductor longus tendon via the anterior pubic ligament, and it introduces the new anatomical concept of the pyramidalis-anterior pubic ligament-adductor longus complex (PLAC). Knowledge of these anatomical relationships should be employed to aid in image interpretation and treatment planning with proximal adductor avulsions. In particular, MRI imaging should be employed for all proximal adductor longus avulsions to assess the integrity of the PLAC.

Groin pain encompasses a number of conditions from the lower abdomen, inguinal region, proximal adductors, hip joint, upper anterior thigh and perineum. The complexity of the anatomy, the heterogeneous terminology and the overlapping symptoms of different conditions that may co-exist epitomise the challenges in diagnosis and treatment. Inguinal-related and adductor-related pain is the most common cause of groin pain and will be discussed in this article.

Groin pain is common in athletes. Yet, there is disagreement on aetiology, pathomechanics and terminology. A plethora of terms have been employed to explain inguinal-related groin pain in athletes. Recently, at the British Hernia Society in Manchester 2012, a consensus was reached to use the term inguinal disruption based on the pathophysiology while lately the Doha agreement in 2014 defined it as inguinal-related groin pain, a clinically based taxonomy. This review article emphasizes the anatomy, pathogenesis, standard clinical assessment and imaging, and highlights the treatment options for inguinal disruption.

Background: Heterogeneous taxonomy of groin injuries in athletes adds confusion to this complicated area., Aim: The 'Doha agreement meeting on terminology and definitions in groin pain in athletes' was convened to attempt to resolve this problem. Our aim was to agree on a standard terminology, along with accompanying definitions., Methods: A one-day agreement meeting was held on 4 November 2014. Twenty-four international experts from 14 different countries participated. Systematic reviews were performed to give an up-to-date synthesis of the current evidence on major topics concerning groin pain in athletes. All members participated in a Delphi questionnaire prior to the meeting., Results: Unanimous agreement was reached on the following terminology. The classification system has three major subheadings of groin pain in athletes: 1. Defined clinical entities for groin pain: Adductor-related, iliopsoas-related, inguinal-related and pubic-related groin pain. 2. Hip-related groin pain. 3. Other causes of groin pain in athletes. The definitions are included in this paper., Conclusions: The Doha agreement meeting on terminology and definitions in groin pain in athletes reached a consensus on a clinically based taxonomy using three major categories. These definitions and terminology are based on history and physical examination to categorise athletes, making it simple and suitable for both clinical practice and research., (Published by the BMJ Publishing Group Limited.

Background: Chronic adductor enthesopathy is a well-known cause of groin pain in athletes. Currently, percutaneous nonselective adductor tenotomies give mixed results and not always predictable outcomes., Hypothesis: A selective partial adductor longus release as treatment for recalcitrant chronic adductor longus enthesopathy provides excellent pain relief with a prompt and consistent return to preinjury levels of sport., Study Design: Case series; Level of evidence, 4., Methods: All athletes were assessed in a standard way for adductor dysfunction. They received radiographs and a specifically designed magnetic resonance imaging groin study protocol. Only professional athletes who received a selective partial adductor release were included. Pain and functional improvement were assessed with the visual analog scale (VAS) pain score and time to return to sport., Results: Forty-three professional athletes (39 soccer and 4 rugby) with chronic adductor-related groin pain were treated with a selective partial adductor release. The average follow-up time was 40.2 months (range, 25-72 months). Forty-two of 43 athletes returned to their preinjury level of sport after an average of  9.21 weeks (range, 4-24 weeks; SD, 4.68 weeks). The preoperative VAS score improved significantly (Wilcoxon signed-rank test, P < .001) from 5.76 ± 1.08 (range, 3-8) to 0.23 ± 0.61 (range, 0-3) postoperatively., Conclusion: A selective partial adductor longus release provides excellent pain relief for chronic adductor enthesopathy in professional athletes with a consistent high rate of return to the preinjury level of sport.

The management of Achilles tendon rupture is a much-debated subject. In recent years, there has been much interest in early postoperative mobilization. We present the results of our Achilles tendon repair technique and accelerated rehabilitation program. The technique we propose uses the strength of a 1-loop polydioxanone "suture frame" to enable restoration of the tendon length, immediate positioning of the foot in a near-plantigrade position, and an accelerated rehabilitation program. We followed up 15 cases of Achilles tendon rupture treated with this technique. The initial follow-up was a review of case notes and a telephone questionnaire. All patients were subsequently invited for a clinical follow-up visit, and 11 patients (68.75%) attended. No cases of infection or repeat rupture occurred. The return to work (mean 5.6 weeks) and return to sport (mean 4.8 months) were relatively rapid. Regarding overall satisfaction on a scale of 0 to 10, the median was 9 (range 8 to 10). Of the 11 patients who attended the clinical follow-up visit, the mean American Orthopaedic Foot and Ankle Surgery ankle-hindfoot score was 94.5 points (range 83 to 100). The Achilles rupture repair scores (including isokinetic muscle strength) were good or excellent in all but 1 patient, whose result was fair. Of the 11 patients, 10 reported complete satisfaction with their outcome. Our technique with accelerated rehabilitation is safe and effective in the management of acute Achilles tendon rupture. It facilitates an early return to work and recreational sports, with excellent overall patient satisfaction., (Copyright © 2012 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

We present a case of a high-level rugby player with severe groin pain following a partial rupture of his left adductor longus enthesis during a game. Conservative treatment proved unsuccessful and the athlete had persistent symptoms, affecting his quality of life and ability to play sports. Further assessments revealed a large bony spur/enthesophyte at adductor longus origin. The patient underwent a successful surgical resection of the active bone formation.

We report a rare case of late knee locking after an open knee injury in a polytrauma patient with a pelvic fracture and a contralateral femoral artery injury. Once the life and limb threatening injuries were addressed, debridement and washout of the knee wound was performed. X-rays and subsequent CT revealed only an undisplaced patella fracture. The patient presented 6 months later to a knee surgeon with recurrent locking. An arthroscopy was performed and a 10 mm plastic soft drink bottle cap was retrieved leading to the immediate resolution of symptoms without complications.Open knee injuries require thorough debridement washout and joint assessment. Late locking should raise the suspicion of an intra-articular loose or foreign body. Arthroscopy is an excellent first line tool in the diagnosis and late management of this unusual problem.

Metatarsal stress fractures are uncommon in the children. They usually occur in the distal part of the metatarsal and common in second and third metatarsals. Stress fracture in the proximal fourth metatarsal in a child is very rare. We report a stress fracture in the proximal fourth metatarsal in an 8-year-old boy, which was successfully treated with non-operative management.

Background: Adductor dysfunction can cause groin pain in athletes and may emanate from the adductor enthesis. Adductor enthesopathy may be visualized with magnetic resonance imaging and may be treated with entheseal pubic cleft injections. We have previously reported that pubic cleft injections can provide predictable pain relief at one year in competitive athletes who have no evidence of enthesopathy on magnetic resonance imaging and immediate relief only in patients with findings of enthesopathy on magnetic resonance imaging. In this follow-up study, we attempted to determine if the same holds true for recreational athletes., Methods: We reviewed a consecutive case series of twenty-eight recreational athletes who had presented to our sports medicine clinic with groin pain secondary to adductor longus dysfunction. A period of conservative treatment had failed for all of these athletes. The adductor longus origin was assessed with magnetic resonance imaging for the presence or absence of enthesopathy. All patients were treated with a single pubic cleft injection of a local anesthetic and corticosteroid into the adductor enthesis. The patients were assessed for recurrence of symptoms at one year after treatment., Results: On clinical reassessment five minutes after the injection, all twenty-eight athletes reported resolution of the groin pain. Fifteen patients (Group 1) had no evidence of enthesopathy on magnetic resonance imaging, and thirteen patients (Group 2) had findings of enthesopathy on magnetic resonance imaging. At one year after the injection, five of the fifteen patients in Group 1 had experienced a recurrence; these recurrences were noted at a mean of fourteen weeks (range, seven to twenty weeks) after the injection. Four of the thirteen patients in Group 2 had experienced a recurrence of the symptoms at one year, and these recurrences were noted at a mean of eight weeks (range, two to nineteen weeks) after the injection. Overall, nineteen (68%) of the twenty-eight athletes had a good result following the injection. Of the remaining nine athletes, two were treated successfully with repeat injection; therefore, overall, twenty-one (75%) of the twenty-eight athletes had a good result after entheseal pubic cleft injection., Conclusions: Most recreational athletes with adductor enthesopathy have pain relief at one year after entheseal pubic cleft injection, regardless of the findings on magnetic resonance imaging. There were similarities between this group of recreational athletes and the competitive athletes in our previous study, in that the adductor enthesis was the source of pain and entheseal pubic cleft injection was a valuable treatment option. The main difference was that, in this group of recreational athletes, magnetic resonance imaging evidence of adductor enthesopathy did not correlate with the outcome of the injection.

Objective: The purpose of this article is to define the relations of the symphysis pubis and capsular tissues to the adductor and rectus abdominis soft-tissue attachments on cadaver dissection and correlate with MRI of the anterior pelvis., Subjects and Methods: Seventeen cadavers (8 males and 9 females; mean age, 80 years) were dissected bilaterally. Rectus abdominis and adductor muscles were traced to the pubis and further attachments to the pubic symphysis were defined. Ten asymptomatic (mean age, 17; age range, 16.5-29 years) male athletes underwent 1.5-T MRI of the anterior pelvis with two surface microcoils (each 42 mm in diameter). An axial T2-weighted turbo spin-echo (TSE) sequence (TR/TE, 2,609/106; voxel size, 0.4 mm) was obtained. Axial and sagittal 3D T1-weighted fast-field echo (FFE) sequences (25/4.9; voxel size, 0.3 mm) were obtained. Sequences were repeated incorporating fat suppression and i.v. gadolinium. The relation of the symphysis pubis, disk, and capsular tissues to the insertions of the rectus abdominis, adductor muscles, and gracilis were independently evaluated by two experienced radiologists blinded to all clinical details., Results: In all 17 cadaver specimens, the adductor longus and rectus abdominis attached to the capsule and disk of the symphysis pubis, whereas the adductor brevis had an attachment to the capsule in seven specimens and the gracilis in one. All adductor tendons attached to the pubis. In all 10 athletes, the adductor longus and rectus abdominis bilaterally contributed to the capsular tissues and disk. This was only the case for the adductor brevis in four athletes. No other tendons involved the capsular tissues., Conclusion: Cadaver and MRI findings show an intimate relationship between the adductor longus; rectus abdominis; and symphyseal cartilage, disk, and capsular tissues.

Hamstring strains are common. They are usually treated conservatively, with good results. Thus far, the only subset of patients who have been considered for surgery are those with complete avulsions of the attachments. We describe a new clinical entity: partial rupture of the distal semitendinosus tendon; which has failed to settle with conservative treatment; and has been successfully treated by tenotomy.

Purpose: The aim of this review was to correlate the preoperative clinical diagnoses and the diagnostic arthroscopic findings in preadolescents with knee problems. We also studied the incidence of different types of knee pathology in this age group., Type of Study: Consecutive case series., Materials and Methods: Twenty-three preadolescents, 13 girls and 10 boys under the age of 13 years, presenting with mechanical knee problems underwent knee arthroscopy after clinical assessment., Results: Symptomatic plica synovialis was found to be the most frequent pathology (n = 8). This pathology was far more common in girls compared with boys. Anterior cruciate ligament injuries (n = 4) followed symptomatic plica synovialis in frequency. This was an isolated injury in all cases. The arthroscopic findings were negative in 4 patients., Conclusion: In 61% of preadolescent patients, the clinical diagnoses and arthroscopic findings were compatible and correct. The main error tended to be misdiagnosis of meniscal pathology (4 patients) and overdiagnosis (5 cases of negative arthroscopy).
