Abstract
Background Knee osteoarthritis (OA) is common amongst retired male professional footballers. There is limited understanding with respect to the interplay between imaging findings, clinical presentation and patient-reported outcome measures (PROMs) in retired professional footballers with knee OA. Objectives This pilot study aimed to evaluate the extent of radiological and clinical knee OA in a cohort of retired male professional footballers, and to explore the relationship between these findings and knee-related PROMs. Methods Fifteen retired male professional footballers underwent knee radiographs and were surveyed on their history of clinical OA, severe knee injury and previous knee surgery. The Knee Injury and Osteoarthritis Outcome Score Physical Function Short Form (KOOS-PS) and the Patient-Reported Outcomes Measurement Information System Global Health (PROMIS-GH) were used to assess health outcomes, such as level of function and pain. Results Radiological knee OA was diagnosed in six out of 15 participants. Seven of the participants had a clinical diagnosis of knee OA. Evidence of clinical and radiological OA was present amongst four participants. Radiological knee OA and clinical OA was significantly associated with a history of severe knee injury and previous knee surgery. Low correlations (ρ<-0.40) were found between knee OA severity and knee-related PROMs. Moderate correlation (ρ=-0.65) was found between clinical knee OA and KOOS-SP. Conclusion Clinical knee OA correlates with PROMs amongst retired professional footballers but radiological OA does not. Further studies are required to understand the relationship between imaging findings, clinical presentation and PROMs amongst retired professional footballers with knee OA.

Abstract
PURPOSE A thorough understanding of the arthroscopic anatomy is important to recognise pathological conditions. Although some ankle ligaments have been described as intra-articular structures, no studies have assessed the full visibility of these structures. The purpose of this study was to assess arthroscopic visibility of medial and lateral ankle collateral ligaments. METHODS Arthroscopy was performed in 20 fresh frozen ankles. The arthroscope was introduced through the anteromedial portal and the anterior compartment was explored in ankle dorsiflexion without distraction. Intra-articular structures were tagged using a suture-passer introduced percutaneously and they were listed in a table according to the surgeon's identification. After the arthroscopic procedure, the ankles were dissected to identify the suture-tagged structures. RESULTS According to the suture-tagged structures, 100% correlation was found between arthroscopy and dissection. In the anterior compartment, the superior fascicle of the anterior talofibular ligament, the distal fascicle of the anterior tibiofibular ligament and the anterior tibiotalar ligament on the medial side were observed. The deep fascicle of the posterior tibiofibular ligament and the intermalleolar ligament were tagged at the posterior compartment. CONCLUSION Ankle dorsiflexion and non-distraction arthroscopic technique allows full visualisation of the medial and lateral ankle collateral ligaments: the superior fascicle of the anterior talofibular ligament, the distal fascicle of the anterior tibiofibular ligament and the anterior tibiotalar ligament. When using distraction, posterior structures as the deep fascicle of the posterior tibiofibular ligament and the intermalleolar ligament can be observed with anterior arthroscopy.

Abstract
PURPOSE To assess the effectiveness of cadaveric ankle arthroscopy courses in reducing iatrogenic injuries. METHODS A total of 60 novice surgeons enrolled in a basic cadaveric ankle arthroscopy course were divided into two groups. Group A (n = 32) was lectured on portal placement and use of the arthroscope, whereas group B (n = 28) was in addition lectured on specific portal-related complications. Following the performance of anterior ankle arthroscopy and hindfoot endoscopy, the specimens were dissected and carefully assessed for detection of any iatrogenic injuries. RESULTS The rate of injury to the superficial peroneal nerve (SPN) was reduced from 25 to 3.6%, in group A compared with B (p = 0.033). Injuries to the peroneus tertius or extensor digitorum longus, the flexor hallucis longus and the tibial nerve or the Achilles tendon were also reduced in group B. Overall, the number of uninjured specimens was 50% (n = 30) and higher in group B (57%) than group A (44%). Lesions to the plantaris tendon, the sural nerve or the posterior tibial artery were more common in group B, however, without reaching statistical significance. Overall, 25 (13.9%) anatomic structures were injured in anterior arthroscopy compared to 18 (5%) in hindfoot endoscopy, out of a potential total of 180 and 360, respectively (p = 0.001). CONCLUSION Dedicated lectures on portal-related complications have proven useful in reducing the risk of injury to the SPN, the commonest iatrogenic injury encountered in ankle arthroscopy. Hindfoot endoscopy is significantly safer than anterior ankle arthroscopy in terms of injury to anatomical structures.

Abstract
PURPOSE Despite the increased use of ankle dorsiflexion without distraction, no reports have specifically addressed the arthroscopic anatomy of the ankle in this position. The purpose of this study was to describe the normal arthroscopic anatomy of the ankle joint, when using the ankle dorsiflexion and the dynamic distraction technique, and to propose an arthroscopic examination system for the anterior ankle compartment. METHODS Ankle arthroscopy was performed in 20 fresh frozen specimens. Arthroscopic examination was performed with the arthroscope introduced through the anteromedial portal. The anterior compartment was examined in ankle dorsiflexion without distraction. The compartment was examined in four steps: (1) lateral area including the lateral gutter; (2) the central area of the anterior tibial rim; (3) the medial area including the medial gutter; (4) the talar neck. Next, distraction was applied to visualise the anterior compartment again and to examine the central and posterior ankle compartments. RESULTS Anatomic intra-articular structures were visualised in all specimens. Four intra-articular fat pads, one anteromedial, two syndesmotic and another posteromedial, were constantly observed. A description of the normal arthroscopic anatomy of the ankle using the ankle dorsiflexion and the dynamic distraction technique is detailed for the anterior, central and posterior compartments. CONCLUSION The ankle arthroscopic procedure without distraction allows constant visualisation of the ATFL's superior fascicle on the floor of the lateral gutter, the ATiFL's distal fascicle laterally and the most anterior margin of the deltoid ligament in the medial gutter (anterior tibiotalar ligament). However, ankle distraction is required to observe the central and posterior compartments, but it does not provide optimal visualisation of the anterior ankle compartment structures.

Abstract
BACKGROUND Accurate assessment of articular involvement of the posterior malleolar fracture fragments in ankle fractures is essential, as this is the leading argument for internal fixation. The purpose of this study is to assess diagnostic accuracy of measurements on plain lateral radiographs. METHODS Quantification of three-dimensional computed tomography (Q-3D-CT) was used as a reference standard for true articular involvement (mm(2)) of posterior malleolar fractures. One-hundred Orthopaedic Trauma surgeons were willing to review 31 trimalleolar ankle fractures to estimate size of posterior malleolus and answer: (1) what is the involved articular surface of the posterior malleolar fracture as a percentage of the tibial plafond? and (2) would you fix the posterior malleolus? RESULTS The average posterior malleolar fragment involved 13.5% (SD 10.8) of the tibial plafond articular surface, as quantified using Q-3D-CT. The average involvement of articular surface of the posterior malleolar fragment, as estimated by 100 observers on plain radiographs was 24.4% (SD 10.0). The factor 1.8 overestimation of articular involvement was statistically significant (p<0.001). Diagnostic accuracy of measurements on plain lateral radiographs was 22%. Interobserver agreement (ICC) was 0.61. Agreement on operative fixation, showed an ICC of 0.54 (Haraguchi type I=0.76, Haraguchi type II=0.40, Haraguchi type III=0.25). CONCLUSIONS Diagnostic accuracy of measurements on plain lateral radiographs to assess articular involvement of posterior malleolar fractures is poor. There is a tendency to misjudge posteromedial involvement (Haraguchi type II).

Abstract
OBJECTIVE The objective of this study was to determine the prevalence of symptoms related to mental disorders (distress, anxiety/depression, sleep disturbance, adverse alcohol behaviour, adverse smoking behaviour, adverse nutrition behaviour) among retired professional footballers, and to explore their associations with stressors i.e. determinants such as severe injury, surgery, life events and career dissatisfaction. METHOD Cross--sectional analyses were conducted on baseline questionnaires from an ongoing prospective cohort study among retired male professional footballers. Based on validated questionnaires to assess both stressors and symptoms related to mental disorders, an electronic questionnaire was set up and distributed by players' unions in 11 countries across three continents. RESULTS Prevalence of symptoms related to mental disorders among 219 retired professional footballers ranged from 11% for adverse smoking behaviour and 18% for distress, to 35% for anxiety/depression and 65% for adverse nutrition behaviour. Especially life events that occurred in the previous six months was positively associated with distress (OR=1.3; 95%CI 1.0--1.6), anxiety/depression (OR=1.6; 95%CI 1.2--2.1), sleeping disturbance (OR=1.3; 95%CI 1.1--1.7) and adverse nutrition behaviour (OR=1.4; 95%CI 1.0--1.8). CONCLUSIONS A high prevalence of symptoms related to mental disorders was found among retired professional footballers, confirming a previous study in a similar study population. Relationships were established between symptoms of mental disorders and severe injuries, recently occurred life events, and career dissatisfaction.

Abstract
BACKGROUND Since simulators offer important advantages, they are increasingly used in medical education and medical skills training that require physical actions. A wide variety of simulators have become commercially available. It is of high importance that evidence is provided that training on these simulators can actually improve clinical performance on live patients. Therefore, the aim of this review is to determine the availability of different types of simulators and the evidence of their validation, to offer insight regarding which simulators are suitable to use in the clinical setting as a training modality. SUMMARY Four hundred and thirty-three commercially available simulators were found, from which 405 (94%) were physical models. One hundred and thirty validation studies evaluated 35 (8%) commercially available medical simulators for levels of validity ranging from face to predictive validity. Solely simulators that are used for surgical skills training were validated for the highest validity level (predictive validity). Twenty-four (37%) simulators that give objective feedback had been validated. Studies that tested more powerful levels of validity (concurrent and predictive validity) were methodologically stronger than studies that tested more elementary levels of validity (face, content, and construct validity). CONCLUSION Ninety-three point five percent of the commercially available simulators are not known to be tested for validity. Although the importance of (a high level of) validation depends on the difficulty level of skills training and possible consequences when skills are insufficient, it is advisable for medical professionals, trainees, medical educators, and companies who manufacture medical simulators to critically judge the available medical simulators for proper validation. This way adequate, safe, and affordable medical psychomotor skills training can be achieved.

Abstract
PURPOSE Systematically search and analyse the results of surgical and non-surgical treatments for insertional Achilles tendinopathy. METHODS A structured systematic review of the literature was performed to identify surgical and non-surgical therapeutic studies reporting on ten or more adults with insertional Achilles tendinopathy. MEDLINE, CINAHL, EMBASE (Classic) and the Cochrane database of controlled trials (1945-March 2011) were searched. The Coleman methodology score was used to assess the quality of included articles, and these were analysed with an emphasis on change in pain score, patient satisfaction and complication rate. RESULTS Of 451 reviewed abstracts, 14 trials met our inclusion criteria evaluating 452 procedures in 433 patients. Five surgical techniques were evaluated; all had a good patient satisfaction (avg. 89 %). The complication ratio differed substantially between techniques. Two studies analysed injections showing significant decrease in visual analogue scale (VAS). Eccentric exercises showed a significant decrease in VAS, but a large group of patients was unsatisfied. Extracorporeal shockwave therapy (ESWT) was superior to both wait-and-see and an eccentric training regime. One study evaluated laser CO(2), TECAR and cryoultrasound, all with significant decrease in VAS. CONCLUSIONS Despite differences in outcome and complication ratio, the patient satisfaction is high in all surgical studies. It is not possible to draw conclusions regarding the best surgical treatment for insertional Achilles tendinopathy. ESWT seems effective in patients with non-calcified insertional Achilles tendinopathy. Although both eccentric exercises resulted in a decrease in VAS score, full range of motion eccentric exercises shows a low patient satisfaction compared to floor level exercises and other conservative treatment modalities.

Abstract
BACKGROUND Patellofemoral pain syndrome is a frequently reported condition in active adults. A wide variety of conservative treatment strategies have been described. As yet, no optimal strategy has been identified. Application of orthotic devices e.g. knee braces, knee straps, forms of taping of the knee, active training devices, knee sleeves and in-shoe orthotics to support the foot have been advocated to treat this condition. OBJECTIVES To assess the effectiveness of foot and knee orthotics for treatment of patellofemoral pain syndrome. SEARCH STRATEGY We searched the Cochrane Musculoskeletal Injuries Group specialised register (December 2001), the Cochrane Controlled Trials register (Issue 2, 2000), MEDLINE (January 1966 to March 2000; EMBASE (January 1988 to March 2000); CINAHL (January 1982 to March 2000) and PEDro (up to March 2000). Relevant orthotic companies were contacted. SELECTION CRITERIA All randomised and quasi-randomised trials comparing the effectiveness of knee or foot orthotics for treatment of patellofemoral pain syndrome were selected. Trials describing the use of orthotic devices in conjunction with operative treatment were excluded. DATA COLLECTION AND ANALYSIS Three reviewers independently assessed methodological quality of the identified trials by use of a modified version of the Cochrane Musculoskeletal Injuries Group assessment tool, consisting 11 items. Two reviewers extracted data without blinding. Trialists were contacted to obtain missing data. MAIN RESULTS Five trials involving 362 participants were included in this review. Five other trials await possible inclusion if further information can be obtained and one awaits further assessment. Due to clinical heterogeneity, we refrained from statistical pooling and conducted analysis by grading the strength of scientific evidence. The level of obtained research-based evidence was graded as limited as all trials were of low methodological quality. This limited research-based evidence showed the Protonics orthosis at six week follow-up was significantly more effective for decrease in pain (weighted mean difference (WMD) between groups 3.2; 95% confidence interval (CI) 2.8 to 3.6), functional improvement on the Kujala score (WMD 45.6; 95% CI 43.4 to 47.7) and change in patellofemoral congruence angle (WMD 17.2; 95% CI 14.1 to 20.3) when compared to no treatment. A comprehensive programme including tape application was significantly superior to a monitored exercise programme without tape application for decrease in worst pain (WMD 1.6; 95% CI 0.4 to 2.8) and usual pain (WMD 1.2; 95% CI 0.2 to 2.1), and clinical change and functional improvement questionnaire scores (WMD 10, 95% CI 2.07 to 17.93) at four weeks follow-up. The trials reported statistically significant differences in patient satisfaction after applied therapy (WMD 3.3; 95% CI 0.5 to 6.1) in favour of the McConnell regimen compared with the Coumans bandage at six weeks follow-up. REVIEWER'S CONCLUSIONS The evidence from randomised controlled trials is currently too limited to draw definitive conclusions about the use of knee and foot orthotics for the treatment of patellofemoral pain. Future high quality trials in this field are warranted.

Abstract
OBJECTIVE To provide a clear overview of the literature on the relationship between increased lateral ankle ligament damage and anterior talocrural-joint laxity. DESIGN A systematic review of the literature. BACKGROUND Diagnostic methods for inversion injuries of the ankle have remained controversial throughout the years. An instrumented test for anterior talocrural-joint laxity could be a diagnostic tool for evaluation of anterior lateral ankle ligament function. METHODS An advanced electronic database search using MEDLINE and EMBASE was performed to find studies describing the correlation between lateral ankle ligament damage and talocrural-joint laxity. Two reviewers assessed the methodological quality for each study and agreement was noted. Two reviewers extracted all relevant data with respect to methodology, motion constraints and laxity measurement. RESULTS The quality assessment resulted in 5 studies being scored as high quality and 5 as low quality. Different test devices were used to apply the load and measure the displacement. All in vitro tests applied a load to the calcaneus and subsequently measured the translation of the talus and/or calcaneus relative to the tibial dome. Rotation in the transversal and frontal plane was restricted in 8 tests. After analysis of the results presented by nine different studies, the mean value of anterior talocrural-joint laxity with intact ligaments is 4.2 mm. After sectioning of the anterior talofibular ligament, the mean anterior laxity value is 6.5 mm. The mean anterior laxity value after sectioning of the calcaneofibular ligament increases to 8.4 mm. The mean anterior laxity value with the foot in dorsal flexion (3.1 mm) is less than the mean value with the foot in neutral position (4.5 mm) or in plantar flexion (4.7 mm). The applied load and the anterior laxity values between the different studies vary greatly. CONCLUSIONS Each ligament section results in significantly increased talocrural-joint laxity. Talocrural-joint laxity can be used as a measure for damage to the anterior talofibular ligament and/or the calcaneofibular ligament. From this review, it is neither possible to give universal recommendations about the optimal flexion angle for testing talocrural-joint laxity as a measure for lateral ankle ligament function, nor to recommend the ideal load for performing the test. RELEVANCE The development of an instrumented test as a diagnostic tool for anterior talocrural-joint laxity in the clinical setting is near at hand and practicable.

Abstract
The variation of practice with respect to the treatment of the acutely sprained ankle suggests a lack of evidence-based management strategies for this problem. The objective of this review was to assess the effectiveness of the various methods of immobilisation for acute ankle sprain. An electronic database search was conducted using MEDLINE, EMBASE, BIOSIS, CINAHL, Cochrane Controlled Trial Register and Current Contents. Randomised and quasi-randomised clinical trials describing skeletally mature individuals with an acute ankle sprain and comparing immobilisation for the treatment of injuries to the lateral ligament complex of the ankle were evaluated for inclusion. Two reviewers independently assessed the validity of included trials and extracted relevant data on the treatment outcome. Where appropriate, results of comparable studies were pooled. Individual and pooled statistics are reported as relative risks (RR) for dichotomous outcomes and weighted mean differences (WMD) for continuous outcome measures with 95% confidence intervals (95% CI). Heterogeneity between trials was tested using a standard chi-square test. A total of 22 studies met the inclusion criteria. Statistically significant differences were found for six outcome measures, all in favour of functional treatment compared with immobilisation: return to sports (RR: 1.85; 95% CI: 1.2 to 2.8), (WMD: 4.57 days; 95% CI: 1.5 to 7.6), return to work (WMD: 7.12 days; 95% CI: 5.6 to 8.7), persistent swelling (RR: 1.44; 95% CI: 1.1 to 2.0), objective instability by stress X-ray (WMD: 2.48; 95% CI: 1.3 to 3.6), range of motion (RR: 1.64; 95% CI: 1.1 to 2.6) and patient satisfaction (RR: 6.50; 95% CI: 1.8 to 24) . None of the other results were significantly in favour of immobilisation. Sensitivity analysis showed that a non-concealed treatment allocation did not influence the statistical significance of the overall results. Based on our results, functional treatment currently seems a more appropriate treatment and should be encouraged. Concerning effectiveness, immobilisation, if necessary, should be restricted to certain patients and for short time periods.

Abstract
We report the results of 238 consecutive patients who underwent in total 261 acromioplasties because of chronic rotator cuff impingement. The procedure was performed either in conventional open technique (80) or arthroscopically (181). Two years (1-10) after the operation 68% of the patients treated with the open technique had an excellent or good result compared 82% of the patients treated arthroscopically by an experienced arthroscopic surgeon. Compared to the open technique, the arthroscopic procedure had a statistically significant superior result concerning outcome, operating time and hospital stay. Arthroscopic procedures performed by less experienced surgeons had inferior results.

Abstract
BACKGROUND Although high tibial osteotomy has been proved effective for the treatment of painful osteoarthritis of the medial compartment of the knee, the role of proximal tibial varus osteotomy for the treatment of painful osteoarthritis of the lateral compartment still remains controversial. METHODS From 1974 to 1993, we performed proximal tibial varus osteotomy for the treatment of osteoarthritis of the lateral compartment of the knee in thirty-six consecutive patients. The procedure consisted of a proximal lateral opening-wedge varus osteotomy of the tibia with use of corticocancellous bone grafts from the iliac crest. The valgus deformity was posttraumatic in twenty-three patients, followed a lateral meniscectomy in five, was due to overcorrection of a varus deformity in four, and was idiopathic in four. The preoperative valgus deformity averaged 11.6 degrees (range, 4 degrees to 22 degrees ). RESULTS At a mean of eleven years (range, five to twenty-one years) after the operation, the clinical results for thirty-four of the thirty-six patients were analyzed. None of the patients had severe progression of the osteoarthritis after the osteotomy, and none had a meaningful loss in the range of motion of the knee joint. A superficial wound infection developed in one patient, and another patient had thrombophlebitis. Three patients (9%) had a transient palsy of the peroneal nerve. According to the system of Insall et al., the mean knee score was 84 points (range, 54 to 99 points). According to the knee score described by Lysholm and Gillquist, the subjective result was excellent in nine patients (26%), good in twenty-one (62%), fair in three (9%), and poor in one (3%). CONCLUSIONS We concluded that when the indications outlined in this study are followed and our opening-wedge technique is used, a proximal lateral opening-wedge varus osteotomy of the tibia is a good alternative for the treatment of isolated osteoarthritis of the lateral compartment of the knee. High accuracy in preoperative planning, based on a slight overcorrection, is important to prevent failure.

Abstract
There is increasing evidence that cytogenetically invisible chromosome rearrangements are an important cause of genetic disease. Clues to the chromosomal location of these rearrangements may be provided by a specific clinical diagnosis, which can then be investigated by targeted FISH or molecular studies. However, the phenotypic features of some microdeletion syndromes are difficult to recognise, particularly in infants. In addition, the presence of other chromosome aneuploidy may mask the typical clinical features. In the present study, the presence of tubers on cranial magnetic resonance imaging (MRI) of a 5-week-old infant prompted an investigation, by FISH, with probes from the tuberous sclerosis gene, TSC2. This and further FISH deletion mapping studies revealed a submicroscopic deletion encompassing the entire TSC2 gene and the adjacent PKD1 gene on one chromosome 16, confirming a del(16)(p13.3). Because of the large number of abnormal phenotypic features in this infant, we performed a 12-colour FISH assay (M-TEL) to screen for subtelomeric rearrangements involving the del(16p). The M-TEL assay revealed a cryptic der(16)t(16;19)(p13.3;p13.3). Further FISH with 19p and 19q subtelomeric probes demonstrated that this was derived from a balanced maternal t(16;19)(p13.3;p13.3). Importantly, 24-colour painting by multiplex FISH (M-FISH) failed to detect the translocation in either the infant or his mother. Based on our FISH mapping studies, we estimate the size of the trisomic region from 19p13.3 to be approximately 2 Mb, and the region of monosomy for 16p13.3 as 2.25 Mb. This case adds to the growing literature which indicates that many apparent chromosomal deletions are unbalanced translocations. The M-TEL assay provides a sensitive alternative to M-FISH for the detection of these subtle telomeric rearrangements.
