The effectiveness of hydrotherapy on return to play in sports following hip arthroscopic surgery: a comparative study.

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.

The use of sand as an alternative surface for training, injury prevention and rehabilitation in English professional football and barriers to implementation: a cross-sectional survey of medical staff.

PURPOSE: The purpose of the present study was to investigate the use of sand as an alternative surface for training, injury prevention and rehabilitation interventions in English professional football. A Secondary aim was to explore the potential barriers to implementation. MATERIALS AND METHODS: All 92 teams from the male English professional football pyramid during the 2021-22 season were eligible to take part. A cross-sectional survey of the medical personnel (one per club) was conducted between June 2021 and December 2021 based on the RE-AIM framework. A total of 58 respondents (63% of all clubs) completed the survey. RESULTS AND CONCLUSIONS: Only 18 (31%) of the clubs surveyed used sand-based interventions across the last 3 seasons. Respondents felt sand-based interventions would be effective at improving physiological gains (median 4, interquartile range [IQR] 4-5) and as part of injury prevention and rehabilitation strategies (4, IQR 3-4) but were indifferent in relation to its potential to improve sporting performance (3, IQR 3-4). Barriers to implementation of sand-based interventions within wider football were a lack of facilities, lack of awareness of its potential benefits, lack of high-quality evidence and the surface not being specific to the sport. Medical staff also did not perceive that coaches' positively viewed sand interventions as a training or injury management strategy.

Effect of Sand on Knee Load During a Single-Leg Jump Task: Implications for Injury Prevention and Rehabilitation Programs.

Richardson, MC, Murphy, S, Macpherson, T, English, B, Spears, I, and Chesterton, P. Effect of sand on knee load during a single-leg jump task: implications for injury prevention and rehabilitation programs. J Strength Cond Res 34(11): 3164-3172, 2020-The purpose of the study was to determine potential differences in landing strategies and subsequent joint loads at the knee (knee abduction moment [KAM], anterior-posterior [AP] tibial translation, and total knee shear force) when jumping onto sand and firm ground from both a level surface and a 30-cm height. Firm ground would act as the control for the study. Seventeen subjects (age: 23.6 ± 3.7 years; body mass: 67.7 ± 10.3 kg; height: 168.5 ± 7.4 cm) performed 3 single-leg jumps on their dominant leg for each of the 4 conditions tested (ground level, sand level, ground height, and sand height). A repeated-measures design investigated the effect of sand on KAM, AP tibial translation, and total knee shear force. Data were analyzed using magnitude-based inferences and presented as percentage change with 90% confidence limits. Results indicated that sand had a clear beneficial effect on KAM, which was possibly moderate during a drop jump (30 cm) and possibly small from a level jump. Sand also had a possibly moderate beneficial effect on AP tibial translation from a level jump. The effect of sand on total knee shear force was unclear. These results suggest that sand may provide a safer alternative to firm ground when performing jump tasks commonly used in anterior cruciate ligament and patellofemoral joint injury prevention and rehabilitation programs. Sand may also allow for an accelerated rehabilitation program because jumping activities could potentially be implemented more safely at an earlier stage in the process.

Points & Pearls: Blunt cardiac injury: emergency department diagnosis and management

Blunt cardiac injury describes a range of cardiac injury patterns resulting from blunt force trauma to the chest. Due to the multitude of potential anatomical injuries blunt force trauma can cause, the clinical manifestations may range from simple ectopic beats to fulminant cardiac failure and death. Because there is no definitive, gold-standard diagnostic test for cardiac injury, the emergency clinician must utilize an enhanced index of suspicion in the clinical setting combined with an evidence-based diagnostic testing approach in order to arrive at the diagnosis. This review focuses on the clinical cues, diagnostic testing, and clinical manifestations of blunt cardiac injury as well as best-practice management strategies.

Nonoperative treatment and return to play after complete proximal adductor avulsion in high-performance athletes.

PURPOSE: To assess the outcome of nonoperative treatment after complete avulsion of the proximal adductor longus tendon in high-performance athletes. METHODS: Six consecutive athletes were included. Treatment was conservative following a strict rehabilitation plan. Following parameters were analysed: basic data, mechanism of injury, classification, tendon retraction, size of defect in MRI and return to play (RTP). RESULTS: Mean age at injury was 28 ± 5 (range 20-32) years. Overstretch (83 %) and kicking (50 %) were the most frequent injury mechanisms, and the dominant leg was involved in 83 %. Average retraction of the avulsed tendon amounted 21 ± 5 mm. Follow-up MRIs demonstrated a gradual reattachment of the tendon in all cases. All athletes returned to full sportive activity on preinjury level within 88.7 ± 12.8 (range 75-110) days with no functional deficiencies. Manual muscle strength was equal to the contralateral side. CONCLUSION: Nonoperative treatment with a healing phase and a strict rehabilitation plan results in a functional, efficient reattachment of the tendon and allows unrestricted RTP. Since these injuries are rare, present study may help sports physicians when dealing with this type of injuries in professional athletes. Return to sports can be expected at approximately 13 weeks after injury, but can take even longer. LEVEL OF EVIDENCE: Case series, Level IV.

Phases of rehabilitation.

Rehabilitation is easy to do badly and difficult to do well. Many people are involved in the process, and must act as a team to support the patient with good communication and teamwork. The whole process can be satisfying to all concerned when dealing with motivated and enthusiastic patients. Measuring the process is achievable and gives credibility and support to the initial hypothesis of the individual's rehabilitation program. Rehabilitation involves creativity using science and art, with the end result being the patient's return to a normal life or ability to excel within their sport.

Terminology and classification of muscle injuries in sport: the Munich consensus statement.

OBJECTIVE: To provide a clear terminology and classification of muscle injuries in order to facilitate effective communication among medical practitioners and development of systematic treatment strategies. METHODS: Thirty native English-speaking scientists and team doctors of national and first division professional sports teams were asked to complete a questionnaire on muscle injuries to evaluate the currently used terminology of athletic muscle injury. In addition, a consensus meeting of international sports medicine experts was established to develop practical and scientific definitions of muscle injuries as well as a new and comprehensive classification system. RESULTS: The response rate of the survey was 63%. The responses confirmed the marked variability in the use of the terminology relating to muscle injury, with the most obvious inconsistencies for the term strain. In the consensus meeting, practical and systematic terms were defined and established. In addition, a new comprehensive classification system was developed, which differentiates between four types: functional muscle disorders (type 1: overexertion-related and type 2: neuromuscular muscle disorders) describing disorders without macroscopic evidence of fibre tear and structural muscle injuries (type 3: partial tears and type 4: (sub)total tears/tendinous avulsions) with macroscopic evidence of fibre tear, that is, structural damage. Subclassifications are presented for each type. CONCLUSIONS: A consistent English terminology as well as a comprehensive classification system for athletic muscle injuries which is proven in the daily practice are presented. This will help to improve clarity of communication for diagnostic and therapeutic purposes and can serve as the basis for future comparative studies to address the continued lack of systematic information on muscle injuries in the literature. WHAT ARE THE NEW THINGS: Consensus definitions of the terminology which is used in the field of muscle injuries as well as a new comprehensive classification system which clearly defines types of athletic muscle injuries. LEVEL OF EVIDENCE: Expert opinion, Level V.

Hamstring muscle injuries in professional football: the correlation of MRI findings with return to play.

BACKGROUND: Hamstring injury is the single most common injury in professional football. MRI is commonly used to confirm the diagnosis and provide a prognosis of lay-off time. OBJECTIVE: To evaluate the use of MRI as a prognostic tool for lay-off after hamstring injuries in professional football players and to study the association between MRI findings and injury circumstances. METHODS: Prospective cohort study where 23 European professional teams, were followed between 2007 and 2011. Team medical staffs recorded individual player exposure and time-loss injuries. Radiological grading was performed using a modified Peetrons classification into four grades where grades 2 and 3 represent fibre disruption. RESULTS: In total, 516 hamstring injuries occurred and 58% of these were examined by MRI. Thirteen per cent were grade 0 injuries, 57% grade 1, 27% of grade 2 and 3% of grade 3. Grade 0 and 1 injuries accounted for 56% (2141/3830 days) of the total lay-off. The lay-off time differed between all four radiological grades of injury (8±3, 17±10, 22±11 and 73±60 days, p<0.0001). Eighty-three per cent of injuries affected the biceps femoris while 11% and 5% occurred to the semimembranosus and semitendinosus, respectively. Re-injuries (N=34/207) constituted 16% of injuries. All re-injuries occurred to the biceps femoris. CONCLUSION: MRI can be helpful in verifying the diagnosis of a hamstring injury and to prognosticate lay-off time. Radiological grading is associated with lay-off times after injury. Seventy per cent of hamstring injuries seen in professional football are of radiological grade 0 or 1, meaning no signs of fibre disruption on MRI, but still cause the majority of absence days.

Groin pain: clinical assessment and the role of MR imaging.

Groin pain is a common problem in the elite athlete and may lead to prolonged inactivity if inadequately treated. Groin pain, arising from injuries to the hip and pelvis, accounts for 5 to 6% of athletic injuries in adults and 10 to 24% of these injuries in children. Lower limb-dominated athletic activities such as football, rugby, ice hockey, running, and ballet are particularly at risk. Comprehensive evaluation of all the anatomical locations prone to injury including the hip joint, sacrum, ilium and proximal femora, pelvic tendon attachments, and pelvic musculature is required. Magnetic resonance (MR) imaging provides superb soft tissue contrast resolution, multiplanar capabilities, and a wide field of view to evaluate many potential causes of groin pain. Careful clinical examination allows the optimal use of MR imaging and MR arthrography to evaluate the articular, osseous, tendinous, and muscular structures, which may be the source of groin pain. Accurate diagnosis is essential for appropriate management and rehabilitation plans. This article reviews the role of clinical assessment in guiding diagnostic imaging and also describes the relevant MR imaging findings in athletes presenting with groin pain.

Imaging in the assessment and management of athletic pubalgia.

This article reviews the clinical, anatomical, and biomechanical basis of pubalgia and relates it to the potential imaging findings and subsequent management. Although the magnetic resonance imaging features typically seen in symptomatic athletes are emphasized, this condition remains a complex clinical problem, and treatment addressing the functional rehabilitation of the entire region is highlighted.

Blunt trauma of the anterior tibial artery in professional footballers.
