Abstract
AIM To compare right ventricular (RV) volumetry using state-of-the-art three-dimensional (3D) transthoracic echocardiography (3DE) and cardiac magnetic resonance imaging (CMR) near-simultaneously in a clinical setting. MATERIALS AND METHODS Forty-seven consecutive patients received comprehensive echocardiography including 3DE within 30 minutes of CMR. RV volumetry was performed offline with semi-automated 3D endocardial border tracing as well as manual delineation of the compacted myocardium in short-axis views by CMR. RESULTS Forty-two examinations (89%) could be analysed offline by 3D RV reconstruction. Mean RV volumes assessed by CMR and 3DE were 215±63 and 127±42 ml for end-diastole (RV-EDV), as well as 110±43 and 62±27 ml for end-systole (RV-ESV). RV-EDV, RV-ESV, and RV stroke volume measured by 3DE were significantly lower than RV volumetry by CMR. Mean bias were -88, -48, and -41 ml, respectively. Mean RV ejection fraction (-EF) showed a non-significant deviation of +2% between 3DE and CMR and the correlation coefficient was r=0.58 for RV-EF. CONCLUSION RV-EF can be assessed reliably using transthoracic 3DE in patients with good image quality; however, absolute RV volumes measured by 3DE show a systematic deviation to CMR volumetry that has been previously neglected and requires careful interpretation regarding anatomical cardiac imaging.

Abstract
Background: Osteochondral lesions (OCL) of the ankle are a common cause of ankle pain. Although the precise pathophysiology has not been fully elucidated, it can be assumed that a variety of factors are responsible, mainly including traumatic events such as ankle sprains. Advances in arthroscopy and imaging techniques, in particular magnetic resonance imaging (MRI), have improved the possibilities for the diagnosis of OCLs of the ankle. Moreover, these technologies aim at developing new classification systems and modern treatment strategies. Material and Methods: This article is a review of the literature. Recommendations of the group "Clinical Tissue Regeneration" of the German Society of Orthopaedics and Traumatology (DGOU) for the treatment of OCLs of the ankle are presented. The review gives a concise overview on the results of clinical studies and discusses advantages and disadvantages of different treatment strategies. Results: Non-operative treatment shows good results for selected indications in children and adolescents, especially in early stages of osteochondritis dissecans (OCD). However, surgical treatment is usually indicated in OCLs in adolescents and adults, depending on the size and location of the lesion. Various arthroscopic and open procedures are frequently employed, including reattachment of the fragment, local debridement of the lesion with fragment removal and curettage of the lesion, bone marrow-stimulation by microfracture or microdrilling (antegrade or retrograde), and autologous matrix-induced chondrogenesis (AMIC®) - with or without reconstruction of a subchondral bone defect or cyst by autologous cancellous bone grafting. Isolated subchondral cysts with an intact cartilage surface can be treated by retrograde drilling and possibly additional retrograde bone grafting. For larger defects or as salvage procedure, osteochondral cylinder transplantation (OATS® or Mosaicplasty®) or matrix-induced autologous chondrocyte transplantation (MACT) are recommended. Transplantation of so-called (osteochondral) mega grafts, such as autologous bone grafts or allografts, are used for very large osteochondral defects that cannot be reconstructed otherwise. Implantation of the so-called "small metal implants" - such as HemiCAP Talus® - is reserved for selected cases after failed primary reconstruction. Corrective osteotomies are indicated in accompanying axial malalignments. Conclusions: There are several different treatment strategies for OCLs, but clinical studies are rare and evidence is limited. Therefore, interventional studies, e.g. randomised controlled trials (RCTs), but also observational studies, e.g. based on data of the Cartilage Registry of the German Society of Orthopaedics and Traumatology (www.knorpelregister-dgou.de), are needed and are recommended by the authors.

Abstract
BACKGROUND Autologous chondrocyte implantation (ACI) is an established and well-accepted procedure for the treatment of localised full-thickness cartilage defects of the knee. METHODS The present review of the working group "Clinical Tissue Regeneration" of the German Society of Orthopaedics and Trauma (DGOU) describes the biology and function of healthy articular cartilage, the present state of knowledge concerning therapeutic consequences of primary cartilage lesions and the suitable indication for ACI. RESULTS Based on best available scientific evidence, an indication for ACI is given for symptomatic cartilage defects starting from defect sizes of more than three to four square centimetres; in the case of young and active sports patients at 2.5cm(2), while advanced degenerative joint disease needs to be considered as the most important contraindication. CONCLUSION The present review gives a concise overview on important scientific background and the results of clinical studies and discusses the advantages and disadvantages of ACI. LEVEL OF EVIDENCE Non-systematic Review.

Abstract
A patient with spondylosis deformans of the cervical spine with no neurological deficits developed rapidly progressive tetraparesis 1 day after a whiplash injury due to a car accident (rear end collision), although initially there were no clinical symptoms. Surgical decompression and spondylodesis led to relief of the neurological deficits. This case demonstrates that even a low grade whiplash injury (grade 1) can cause severe neurological symptoms later and that a degenerative disease of the spine is a predisposing factor.

Abstract
OBJECTIVE The aim of this study was to perform a macroscopic, spectroscopic and biochemical/histological examination of the defect margins of grade IIIb cartilage lesions in the patella, the medial femoral condyle, the corresponding articular surface and the remaining cartilage surfaces of the knee joint. Our null hypothesis was that there would be no difference in characteristics between the cartilage surrounding the defect, the corresponding articular surface and the remaining articular surfaces of the knee joint on the one hand and the cartilage within the defect on the other. METHOD The study included ten patients treated for focal cartilage lesions (ICRS classification grade IIIb) by autologous cartilage transplantation (ACT). All patients underwent a preoperative magnetic resonance imaging scan (1, 5 T). The articular cartilage lesions were classified pursuant to the recommendations of the International Cartilage Repair Society (ICRS). During the arthroscopic procedure, spectroscopic examinations were performed to measure the degree of cartilage degeneration in a total of 14 defined areas including the defect itself and the region of the defect margins. Biopsies for a histological and biochemical examination (collagen II, glycosaminoglycan, DNA) were taken from the centre of the defect and the defect margins that seemed to be intact on macroscopic examination. RESULTS All knee joints had focal grade IIIb cartilage lesions with an intact margin and an intact corresponding articular surface. The readings obtained on spectroscopic examination both in the defect, the apparently intact margins, the corresponding articular surface and all other examined areas of the knee suggested that severe degenerative changes had already occurred in the cartilage. The histological and biochemical examinations of the residual cartilage in the centre of the defect and the apparently intact margins revealed no significant differences. CONCLUSIONS Focal cartilage lesions frequently occur in the main weight-bearing zones of the patella and the medial femoral condyle. If they are the result of degenerative changes in the knee joint, the residual cartilage in the defect does not differ from the cartilage of the defect margins, the corresponding articular surface and the other cartilage surfaces. This leads to the conclusion that focal cartilage defects seen in degenerative joint damage are only one aspect of general joint degeneration.

Abstract
BACKGROUND Non-destructive techniques for the detection and classification of pathological changes of cartilage in the early stages of osteoarthritis are required for arthroscopic and open surgery of joints. Biochemical and histological changes in cartilage with different degrees of destruction were analysed and correlated to changes in the spectroscopic characteristics of cartilage. PATIENTS, MATERIAL AND METHODS 24 patients (n = 25 knees) with severely destructed knee joints received total knee replacement. The cartilage of the resected joints was classified according to the ICRS system. Defined cartilage specimens were investigated spectroscopically employing NIRS (near-infrared spectroscopy). In the following the cartilage specimens were harvested to determine the content of proteoglycan (GAG) and hydroxyproline (HP) as an essential part of collagen. Histological evaluation of the Mankin score and Otte score was performed using haematoxylin/eosin and safranin-O staining. Spearman's rank correlation coefficient was used to characterise links between the parameters investigated. RESULTS We found significant correlations between spectroscopic, histological and biochemical characteristics. NIRS corresponded to the content of GAG (ρ = 0.58) and HP (ρ = 0.59), as well as to the Mankin (ρ = 0.55) and Otte (ρ = 0.5) scores. Furthermore, the ICRS classification correlated with histological evaluation (Mankin score ρ = 0.725 and Otte score ρ = 0.736), as to be expected. CONCLUSION Characteristic cartilage changes in different degrees of osteoarthritis can be detected and evaluated by the spectroscopic method NIRS as a non-destructive technique. However, the quality of this technical evaluation cannot compete with biochemical and histological analysis.

Abstract
Autologous chondrocyte transplantation/implantation (ACT/ACI) is an established and recognised procedure for the treatment of localised full-thickness cartilage defects of the knee. The present review of the working group "Clinical Tissue Regeneration" of the German Society of Orthopaedics and Traumatology (DGOU) describes the biology and function of healthy articular cartilage, the present state of knowledge concerning potential consequences of primary cartilage lesions and the suitable indication for ACI. Based on current evidence, an indication for ACI is given for symptomatic cartilage defects starting from defect sizes of more than 3-4 cm2; in the case of young and active sports patients at 2.5 cm2. Advanced degenerative joint disease is the single most important contraindication. The review gives a concise overview on important scientific background, the results of clinical studies and discusses advantages and disadvantages of ACI.

Abstract
We attempted to characterise the biological quality and regenerative potential of chondrocytes in osteochondritis dissecans (OCD). Dissected fragments from ten patients with OCD of the knee (mean age 27.8 years (16 to 49)) were harvested at arthroscopy. A sample of cartilage from the intercondylar notch was taken from the same joint and from the notch of ten patients with a traumatic cartilage defect (mean age 31.6 years (19 to 52)). Chondrocytes were extracted and subsequently cultured. Collagen types 1, 2, and 10 mRNA were quantified by polymerase chain reaction. Compared with the notch chondrocytes, cells from the dissecate expressed similar levels of collagen types 1 and 2 mRNA. The level of collagen type 10 message was 50 times lower after cell culture, indicating a loss of hypertrophic cells or genes. The high viability, retained capacity to differentiate and metabolic activity of the extracted cells suggests preservation of the intrinsic repair capability of these dissecates. Molecular analysis indicated a phenotypic modulation of the expanded dissecate chondrocytes towards a normal phenotype. Our findings suggest that cartilage taken from the dissecate can be reasonably used as a cell source for chondrocyte implantation procedures.

Abstract
AIM In cerebral palsy children with bilateral hip dislocation, a new therapeutic concept was established that treated the less affected hip conservatively and the more affected hip simultaneously with an adductor tenotomy. The current study assessed whether the clinical and radiological outcome was equal to that of established bilateral surgical treatments. We also examined whether this approach leads to an adequate motor function improvement of the affected children. METHOD In 41 children with cerebral palsy and bilateral hip dislocation, a prospective study assessed the hip abduction, migration percentage (MP) and the motor function (Rancho los Amigos scale). Depending on the pretherapeutic status, all patients were grouped into 3 abduction and 3 MP groups. The less affected hip was treated with a hip abduction splint whereas the more affected hip of the same child was simultaneously treated with a subcutaneous adductor tenotomy. All patients were assessed annually for 4 years. RESULTS The hip abduction of the conservatively treated hips was pretherapeutically 41.8 +/- 2.6 degrees and improved significantly after 1 year. Patients with a pretherapeutic hip abduction < or = 20 degrees showed the most improvement. After 4 years, a significant deterioration of abduction was avoided in 49%. The pretherapeutic MP of the conservatively treated hips was 31.6 +/- 3.4% and was significantly but only slightly improved. The 4 year MP was significantly improved and the largest improvement was observed when the pretherapeutic MP was larger than 50%. A significant MP improvement after 4 years was achieved in 54%. After 4 years, 34% had undergone a motor function improvement. In 7% a motor function deterioration was observed. Posttherapeutically, the conservatively treated hips showed abduction and MP values that were comparable to those of surgically treated hip joints. CONCLUSION In cerebral palsy children with bilateral hip dislocation, the conservative treatment of the less affected hip is suitable to achieve clinical and radiological results that are equal to the surgical treatment of the more affected hip. The concept of a combined conservative and surgical treatment of bilateral hip dislocation leads to an adequate motor function improvement that is comparable to established bilateral treatments.

Abstract
The case presented is that of a 23-year-old man suffering from osteochonditis dissecans (OCD) of the medial femoral condyle, in whom a free piece of cartilage had separated off and there was a large osteochondral defect despite numerous operations. After refixation of the fragment failed, an autologous chondrocyte transplantation (ACT) was performed using the sandwich technique. Three years after the operation the patient is very satisfied with the result. The radiological findings show stable repair of the bony and cartilaginous defect area. This case report shows that ACT is a valid method for the treatment of large osteochondral defects even after several previous failed operations. The low donor site morbidity is an important advantage over other methods, such as transplantation of osteochondral plugs.

Abstract
AIM The current study assessed the clinical and radiological outcome and motor function improvement after subcutaneous adductor tenotomy in children with cerebral palsy (ICP). It was also analysed if groups with different preoperative hip functions and radiological hip migrations differed in their final clinical, radiological and motor function outcome. METHOD A prospective study of 91 children with infantile cerebral palsy (ICP, mean age 4.9 years, range: 1.1 - 15.8) with 141 hip dislocations or subluxations analysed preoperatively the hip abduction and radiologically the migration percentage (MP). Depending on the preoperative status, all patients were grouped into 3 abduction and 3 MP groups. Additionally, the motor function was classified according to the Rancho los Amigos scale. A subcutaneous adductor tenotomy was performed mono- or bilaterally and all patients were treated for 4 - 6 weeks with a hip abduction splint. Patients were assessed annually for 4 years; clinical and radiological results and the motor function were analysed according to their preoperative status. RESULTS The mean hip abduction was preoperatively 30.3 +/- 1.2 degrees and was significantly improved to 50.3 +/- 1.3 degrees 1 year and to 43.3 +/- 2.2 degrees 4 years post surgery. The preoperative mean MP was preoperatively 42.3 +/- 1.3 % and was significantly improved to 34.6 % 1 year and to 31.9 % 4 years post surgery. After 4 years, 41 % had undergone a motor function improvement and 52 % no change in motor function. After 4 years, patients with a hip abduction <or= 20 degrees showed the most improvement; other abduction groups also improved significantly but to a lesser extent. The 4-year MP was significantly and to a relatively large extent improved in the groups with a preoperative MP between 25 % and 50 % and above 50 %. With a preoperative MP <or= 25 %, there was a significant but only slight improvement. The motor function was improved when the preoperative hip abduction was most restricted and the preoperative MP was high. CONCLUSION The subcutaneous adductor tenotomy in hip dislocation and subluxation of children with cerebral palsy is a safe procedure that can treat and prevent hip dislocation/subluxation in 76 % of the cases. In appropriately selected patients, the number of individuals that are "freely walking" and "walking with aid" can be doubled. MP and hip abduction are both predictors of therapy outcome.

Abstract
BACKGROUND The incidence of degenerative changes and osteoarthritis is lower in the ankle than in the knee joints. This cannot be explained exclusively with differences in anatomy and biomechanical properties of these two synovial joints. Previous studies have indicated distinct differences in the biochemical composition of the extracellular matrix of articular cartilage from knee and ankle joints. The aim of this study was to identify potential metabolic differences between knee and ankle joint chondrocytes using isolated cells to distinguish the secondary effects of the resident extracellular matrix from the primary matrix-independent effects of cellular differentiation. METHOD Isolated knee and ankle chondrocytes from the same human donor were cultured in alginate beads and subsequently exposed to a three-day pulse of the catabolic cytokine interleukin-1 (IL-1) as a model of an inflammatory episode. The metabolism of proteoglycans (PG's) was analyzed as expressed changes in 35S-sulfate incorporation into glycosaminoglycans (GAG's). RESULTS The presence of IL-1 induced an inhibition of PG synthesis in knee and ankle articular chondrocytes. The 50% inhibitory concentration (IC50) of IL-1 was about 5 times lower for knee than for ankle chondrocytes. CONCLUSION Ankle chondrocytes are more resistant to IL-1 induced inhibition of PG synthesis than chondrocytes from the knee.

Abstract
Diffraction enhanced imaging (DEI) uses refraction of x-rays at edges, which allows pronounced visualization of material borders and rejects scattering which often obscures edges and blurs images. Here, the first evidence is presented that, using DEI, a destruction-free evaluation of the quality of integration of metal implants into bone is possible. Experiments were performed in rabbits and sheep with model implants to investigate the option for DEI as a tool in implant research. The results obtained from DEI were compared to conventional histology obtained from the specimens. DE images allow the identification of the quality of ingrowth of bone into the hydroxyapatite layer of the implant. Incomplete integration of the implant with a remaining gap of less than 0.3 mm caused the presence of a highly refractive edge at the implant/bone border. In contrast, implants with bone fully grown onto the surface did not display a refractive signal. Therefore, the refractive signal could be utilized to diagnose implant healing and/or loosening.

Abstract
Solitary fibrous tumors (SFT) of extremities, especially the thighs are very rare. Despite SFTs are generally benign, well-circumscribed soft tissue tumors new cases should be presented and followed up carefully to monitor their biological behavior. In general for tumor classification a biopsy is state of the art. Histological including immunohistochemical patterns for SFTs are defined. MRI and ultrasound are not sufficient for differential diagnosis. Once property identified and defined by size and location, resection with intact tumor capsule may result in full recovery of the patient. Reviewing the literature there are no validated reasons for a wider resection. The current patient was a 41-year-old male. Four years after an arthroscopy of the left knee the patient has been suffering an ongoing swelling of the lateral thigh. Because MRI scan data suggested a synovial sarcoma a biopsy was performed. The tumor was classified as a benign SFT. The diagnosis based on histological findings and the presence of the positive immunohistochemical markers Vimentin, CD34, and CD99. The complete tumor resection with intact capsule was achieved in a final operation. Clinical and in MRI after 54-month outcome period there were no local recurrences.

Abstract
A patient with degenerative stenosis of the lumbar spinal canal developed paraparesis of both legs following a stable L4 burst fracture. However, neither the stenosis nor the fracture have caused a significant narrowing of the spinal canal. Surgical decompression and dorsal stabilization has led to relief of the neurological deficit. This case demonstrates that even a stable burst fracture may cause paraparesis and that a degenerative spinal canal stenosis is a predisposing factor.

Abstract
Noradrenaline and dopamine content, K+-stimulated release of 3H-noradrenaline, 3H-noradrenaline high-affinity uptake, 3H-prazosin and 3H-rauwolscine binding to alpha 1- and alpha 2-adrenoreceptors, respectively, were studied in isolated visual structures (visual cortex, superior colliculus, lateral geniculate nucleus) of three-month-old rats monocularly deprived by unilateral eyelid closure at postnatal day 11. Monocular deprivation resulted in a number of changes in comparison with normal littermates, mainly in the lateral geniculate nucleus, both ipsilateral and contralateral to the closed eye. K+-stimulated release of noradrenaline and high-affinity noradrenaline uptake were significantly increased, 3H-rauwolscine binding to alpha 2-adrenergic receptor sites was decreased in the contralateral and ipsilateral lateral geniculate nucleus. 3H-Prazosin binding to alpha 1-adrenergic receptors as well as the levels or noradrenaline and dopamine in the lateral geniculate nucleus were unaffected by monocular deprivation. The data support the suggestion that the lateral geniculate nucleus plays a key role in modulating visual information processing and that the lack of an adequate visual input within the first weeks of life interferes mainly with the development of the noradrenergic system at the level of the lateral geniculate nucleus.

Abstract
The density of [3H]dihydroalprenolol binding to beta-adrenergic receptors in the visual structures (visual cortex, superior colliculus and lateral geniculate nucleus) of rats raised under a normal 12 hr light-dark cycle was compared to those of rats visually deprived at different postnatal ages. Unilateral eyelid suture from postnatal days 10 or 16 to 3 months resulted in an increased [3H]dihydroalprenolol bilateral binding in the lateral geniculate nucleus compared to control animals. Monocular deprivation from postnatal days 25, 40, 60 and 90 had no effect on the density of [3H]dihydroalprenolol binding. After re-opening of the eyelid, which was sutured on postnatal day 10, at postnatal day 25 no changes in beta-adrenergic receptor binding in the lateral geniculate nucleus of the adult animal could be detected. After re-opening of the sutured eyelid on day 90, followed by examination of the adrenoceptor density 4 weeks later, the [3H]dihydroalprenolol binding in both lateral geniculate nuclei remained elevated as was also found in corresponding regions of monocular deprived animals. Binocular visual deprivation from postnatal day 10 until the age of 3 months had no effect on [3H]dihydroalprenolol binding in the visual centres in comparison to corresponding control animals. The data suggest that there exists a critical period for the ontogenetic development of beta-adrenergic receptors binding in the visual system of rats during which permanent alterations of receptor binding can be induced by monocular but not binocular visual deprivation.
