Anterior Cruciate

Background: Anterior cruciate ligament (ACL) tears are common injuries; they are often associated with concomitant injuries to other structures in the knee, including bone bruises. While there is limited evidence that bone bruises are associated with slightly worse clinical outcomes, the implications of bone bruises for the articular cartilage and the risk of developing osteoarthritis (OA) in the knee are less clear. Recent studies suggest that the bone bruise pattern may be helpful in predicting the presence of meniscal ramp lesions. Evidence Acquisition: A literature review was performed in EMBASE using the keyword search phrase (acl OR (anterior AND cruciate AND ligament)) AND ((bone AND bruise) OR (bone AND contusion) OR (bone AND marrow AND edema) OR (bone AND marrow AND lesion) OR (subchondral AND edema)). Study Design: Clinical review. Level of Evidence: Level 4. Results: The literature search returned 93 articles of which 25 were ultimately included in this review. Most studies identified a high prevalence of bone bruises in the setting of acute ACL injury. Individual studies have found relationships between bone bruise volume and functional outcomes; however, these results were not supported by systematic review. Similarly, the literature has contradictory findings on the relationship between bone bruises and the progression of OA after ACL reconstruction. Investigations into concomitant injury found anterolateral ligament and meniscal ramp lesions to be associated with bone bruise presence on magnetic resonance imaging. Conclusion: Despite the ample literature identifying the prevalence of bone bruises in association with ACL injury, there is little evidence to correlate bone bruises to functional outcomes or progression of OA. Bone bruises may best be used as a marker for concomitant injury such as medial meniscal ramp lesions that are not always well visualized on magnetic resonance imaging. Further research is required to establish the longitudinal effects of bone bruises on ACL tear recovery. Strength of Recommendation Taxonomy: 2.

The MRI finding of bone marrow oedema, without fracture, following trauma to the scaphoid has been called a ‘bone bruise’. A similar injury is found in the knee, considered benign and managed conservatively. In the scaphoid, there is the concern that this lesion may lead to scaphoid non-union. This study addresses that concern. The clinical and radiological findings of 41 patients with a scaphoid bone bruise on MRI are described, an MRI classification system proposed and clinical outcomes investigated. Patients were immobilised for 6 weeks. At 3 months, 8 remained symptomatic and had repeat MRI. Four of these showed complete resolution of the bruise, the others improvement. At 6 months, 2 of the 8 complained of minor, intermittent discomfort but progressed to resolution of symptoms. This study suggests that the scaphoid bone bruise is a benign injury with predictable recovery and is unlikely to result in long-term morbidity in the form of non-union.

Abstract Introduction MRI is the gold standard for investigation of suspected scaphoid fractures, which can be missed on initial x-rays. This full cycle audit reports the impact of our new patient pathway, which changes repeat x-rays at 2 weeks to urgent limited sequence scaphoid MRI for those with normal initial x-rays, but clinical suspicion of fracture at initial clinic visit. Method A second cycle audited MRI requests for suspected scaphoid fractures at Southmead hospital following implementation of the new pathway in October 2020. We collected wait times from request to scan, and radiologist reports. Results were compared to our first cycle, 6-month time period. Results he results for 24 limited sequence MRIs via our new pathway were compared to 134 full wrist MRIs of the first cycle. Two scans (9.1%) were positive for scaphoid fracture versus 12% in the first cycle. 19 scans (86%) identified alternate pathology including sprain (6), bone bruise (5), non-scaphoid fractures (4) and degenerative change (3). 1 scan (4.5%) was reported as normal. 73% of MRIs were performed within 14 days, compared to 63% in previous cohort. Conclusions Our new pathway using limited sequence MRI identified similar rates of scaphoid fractures. Reduced time to MRI was observed compared to the previous cohort due to shorter scan durations and resulted in earlier diagnosis and fewer outpatient follow-up appointments. Our new pathway has benefits to patient experience and also reduces footfall in hospital, during a time of global Covid-19 pandemic, with no increase in costs.

Tibia Plateau

Aims and Objectives: Anterior cruciate ligament (ACL) ruptures are often concomitated by posterolateral bone bruise in the MRI. This is caused by a ventral subluxation of the tibia and impact of the femur in the posterolateral tibia plateau. In some cases, this impact causes a fracture of the posterolateral tibia plateau, the so-called Apple-Bite-Fracture. The increased posterior slope can cause additional instability and has to be considered as a risk factor for ACL failure. In this study we investigated the short term clinical outcomes of patients with this combined injury. Materials and Methods: Retrospective study of 14 patients (mean age 46 ± 12,3) (8 male, 6 female) with a mean follow up of 23,75 months. Different treatment strategies were analyzed. The clinical evaluation included visual analog score (VAS) increasing from 0-10 for Pain, IKDC Score, Rasmussen score as well as a clinical evaluation. Results: First analysis of the treatment options revealed a non-uniformed therapy strategy. In three patients the ACL tear was treated nonsurgical. In 11 patients the ACL tear was addressed surgical: six times the ACL was reconstructed with hamstring tendon graft, two times the ACL was sutured. Two patients treated with a non-reconstructive technique to promote healing (“healing response”). In one patient a tibial eminence fracture was fixated with a screw. The fracture of the posterolateral tibia plateau was in nine cases minimally invasive reduced and fixated with a screw osteosynthesis in jail technique. Two patients needed posterior buttress plate. Three times the large bone defect has been augmented with autologous bone graft from the pelvis. The postoperative clinical testing did not reveal any persisting knee instabilities. All patient had a non-limited ROM. No significant differences in ROM in comparison to the contralateral knee was seen. One patient reported persisting knee pain (VAS 3). All other patients reported no pain (VAS 0). Subjective IKDC score was 78,18 (71,3 - 83,9; ± 5,68). Clinical Rasmussen scores ranged from 27 to 30 (mean 27, ± 3,0). Rasmussen radiological results ranged from 16 to 18, mean 16,67 (± 1,15). Conclusion: Despite a very small patient number and leck of statistical power the new patient-spedific mini-metal implant seems to be a good options fort he treatment of middle-aged patients who already underwent frustane cartilage surgery. In these relatively rare caes early unicompartimental arthroplasty can be prevented. Further clinical studies with larger patient collectives have to prove the effectiveness of this new technique.

Objective: Traumatic injuries of os scaphoideum are serious, and might lead to two main grades of consequences (i.e. osteoarthrosis or avascular necrosis), if a fracture remains undiagnosed. Bone bruise may be the only pathological sign of pain which can last for week or month. Articles describe the importance of early MRI and hereby predict bone bruise with the help of fat suppression sequence; however, only a limited selection articles compares various fat suppression techniques. The purpose of this prospective study was to compare the short tau inversion recovery (STIR) and T2 fat saturation (FAT SAT) sequences, sectional directed along the scaphoid bone axis. In relation to background fat intensity suppression, this study sought the sequence that best evaluated posttraumatic bone marrow edema (bone bruise) on scaphoid injury musculoskeletal magnetic resonance imaging (MRI, 1.5 T extremity scanner).Materials and methods: Two hundred and fifty-one patients with relevant trauma and positive clinical test for scaphoid bone fractures, exceeding no more than 14 days, underwent MRI examinations. A fast STIR and T2 FAT SAT fast spin echo sequence (FSE) were obtained using a comparable parameter setting (scan time ca. 3 minutes). Three experienced readers (one radiographer and two radiologists) carried out the evaluation blinded to each other’s, based on a quantitative assessment of size (area) and image quality (image contrast, IC and contrast-to-noise ratio, CNR). The study period lasted March 2014-April 2015. Sixty patients met the inclusion criteria and were enrolled. This prospective study was ethically approved by the institutional review board.Results: There were no significant difference between the bone bruise areas (P=0.45, P=0.44 and P=0.83) or CNR (P=0.31, P=0.38 and P=0.17). However, image contrast showed significant difference in favour of T2 FAT SAT in all three readers’ reports (P<0.05, P<0.05 and P<0.05).Conclusions: The two sequences appear almost identical. An interchangeable usage of the two sequences was found being acceptable for the diagnosis if the protocol is composed appropriately (1.5T). However, the T2 FAT SAT provided a higher image contrast by specific settings (e.g. short TI = 125 ms) compared to STIR.

ZusammenfassungHandball zählt zu den beliebtesten Mannschaftssportarten in Deutschland. Bei Diagnostik und Therapie von Schulterverletzungen und Schulterbeschwerden muss zwischen der sportartspezifischen jahrelangen Adaptation und einer vermeintlichen Dekompensation zwingend unterschieden werden. Im Gegensatz zu reinen Wurfsportarten, wie z. B. Baseball oder Speerwerfen, werden im Handball wegen des gleichzeitigen Gegnerkontaktes die beabsichtigten Bewegungsabläufe durch erlaubte und unerlaubte Behinderungen oft plötzlich und ruckartig beeinflusst. Hierdurch können zusätzliche Verletzungen entstehen. Der Übergang einer physiologisch adaptierten Handballer-Schulter zu einer therapiebedürftigen pathologischen Werfer-Schulter ist meist fließend. Die Werfer-Schulter ist durch eine Leistungseinschränkung charakterisiert, die durch Schmerzen in der Schulter bei wiederholter sportartspezifischer Belastung hervorgerufen wird. Neben einer gründlichen klinischen Untersuchung ist, aufgrund der Tatsache, dass Veränderungen der Handballer-Schulter sich in der Muskultur, den Sehnen und im Knochen im Sinne von Überlastungsreaktionen (bone bruise) darstellen, das MRT die bevorzugte Untersuchungsmethode. Neben einer Sportkarenz und einer suffizienten Schmerztherapie sollte eine gezielte Physiotherapie erfolgen. Die Interpretation der MRT-Ergebnisse sollte immer mit den Symptomen und den klinischen Untersuchungsergebnissen abgeglichen werden. Indikationen zur Operation sind eine ausbleibende Besserung nach gezielter Schmerz- und Physiotherapie, strukturelle Schäden entsprechend der Symptome ohne Heilungschance bzw. mit höherer Gewissheit der Verbesserung der Beschwerden und Funktion durch eine Operation. Nach einer operativen Therapie spielt die anschließende Rehabilitation eine große Rolle. Eine Sportfähigkeit ist je nach Verletzung in bis zu 90 % wieder möglich.

Background: Bone bruise characteristics after anterior cruciate ligament (ACL) injury have been correlated with the level of joint derangement in adults. However, the literature lacks information about younger patients, whose higher ligamentous laxity may lead to different lesion patterns. Purpose: To investigate the prevalence, size, location, and role of bone bruise associated with ACL rupture in the pediatric population. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Knee magnetic resonance imaging scans (MRIs) of patients aged 8 to 16 years with ACL tears from 2010 to 2018 were selected from the institution database. Inclusion criteria were open or partially open physes, less than 90 days between trauma and MRI, and no history of injury or surgery. Presence, localization, and size of bone bruise were analyzed by 2 blinded researchers and scored with the Whole-Organ Magnetic Resonance Imaging Score (WORMS) bone bruise subscale. Ligamentous, cartilaginous, meniscal, and other lesions were documented. Results: Of the 78 pediatric patients selected from the database, 54 (69%) had bone bruise. The mean area of bone bruise was larger in males than in females (femur, 3.8 ± 2.8 vs 2.2 ± 1.4 cm2, respectively, P = .006; tibia, 2.6 ± 1.6 vs 1.5 ± 0.8 cm2, respectively, P = .007). The subregions most affected by bone bruise were the lateral posterior tibia and the lateral central femur (in 83% and 80% of the knees affected, respectively). A low correlation was found between age and bone bruise area (biggest areas r = 0.30, P = .03, and sum of areas r = 0.27, P = .04), but no correlation was found between age and WORMS (femur, r = −0.03, P = .85; tibia, r = −0.04, P = .76). The injuries most associated with bone bruise were 23 meniscal lesions (43%), 10 lesions of other ligaments (19.0%), 2 cartilage lesions (3.7%), and 2 patellar fractures (3.7%). Conclusion: The prevalence of bone bruises in pediatric patients with ACL tears is high, although it seems slightly lower than the prevalence documented in adults but with similar localization. The area and the distribution pattern of bone bruises are similar among different ages. The pediatric patients had a lower presence of cartilage and meniscal lesions compared with that reported in adults, which suggests a different effect of this trauma on the knee of pediatric patients.
