The book addresses a range of key topics and discusses emerging approaches that promise to offer effective alternatives to traditional treatments for injuries to bone, cartilage, muscles, ligaments, and tendons. It explains in detail how a variety of innovative products, including biomaterials, growth factors, and autogenous cells, together provide the basis for the regeneration of these musculoskeletal structures and how recent scientific progress has created unique opportunities to address pathological situations that until recently have been treated with unsatisfactory results. The authors are experts from across the world who come together to provide a truly global overview. It will be invaluable for all with an interest in this area of medicine, which has already attained huge popularity in Orthopaedics and Sports Medicine and has also attracted the attention of the lay public. In his youth he played sport at a national level. He performs scientific, surgical and educational activities at a national and international level. He holds various other positions within some of the most prestigious medical societies in the field of orthopedics, arthroscopy, sports medicine and scientific research. He has published hundreds of peer review articles and has been Editor on books and book chapters for various publishing houses. The O. Foundation promotes research into cartilage, joint aging and sports lesions through a network of collaborators from all over the world. John G. His clinical field of practice focuses on complex knee and shoulder injuries.

    The anatomical shape of the leg axis needs to be distinguished between an abduction adjustment with normal anatomical axis of the leg but with pathological positioning and genu valgum as pathology of the anatomic leg axis in its osseous form. This misalignment of the axis develops very early on. It should be noted that natural leg axis development in early childhood, from infancy bow-legged , temporarily changes into knock-knee; however, it is naturally corrected by school age.

    This correction of the natural axial alignment is missing in a subset of morbidly obese children An important consideration is that the knee-joint mechanical loading is much worse in genu valgum knock-knee position than in an abducted soft tissue related position of the lower extremities [Fig. A genu varum bow-leg is not commonly expected among children who are obese, though the incidence of this condition is on the rise in young children On the contrary, genu valgum as a predominant malalignment of the distal extremities is frequent in youth with morbid obesity A recent study showed that, besides static consequences, there are also dynamic implications of said malalignment in obesity.

    Thus, timely guided correction of angular deformity of the knee seems pivotal in order to avoid osteotomy or osteoarthritis later in life. If genu valgum is diagnosed, a minor intervention using temporary epiphysiodesis can help to affect growth positively. On the inner side of the knee depending on the location of the axis problem thigh or lower leg a plate and two screws or a staple are used to stop temporarily the growth of the epiphyseal plate and therefore, correct the leg axis.

    After achieving the correct leg axis position, the osteosynthesis material is removed and growth can continue as usual. Early correction of the axis should be avoided due to the residual risk of over-correction [Fig.

    Conservative therapies using orthotics may affect the leg aspect ratio in the early stages of life. At this time, however, the impact of such devices on further development of the leg axis and the mechanical load due to the adiposity is unknown. An effective prophylaxis is thus unlikely. However, the increased risk for premature arthrosis has to be checked through a three-dimensional load on the joints.

    The joint adjustment in the sagittal profile is, in addition to the frontal plane knock-knee , an especially decisive factor. This is a mechanical overloading particularly of the medial foot structure, which often ends up deformed. As the child grows, the mid foot is exposed to an increased loading stress due to the obesity. It is recommended that children with painful flat feet should participate mainly in non-weight-bearing activities such as swimming, cycling etc.

    Only after losing some weight, should weight-bearing activities, such as running be increased. It is still possible to strengthen the musculotendinous structures in growing children.

    As such, physiotherapy and insertion of a temporary orthotic may be useful to optimise the position of the foot during gait. If significant weight loss is not expected and if weight bearing physical activity is to be optimised, it may be necessary to prescribe custom orthotics for the adolescent. Children with diabetes mellitus especially require a large pressure distribution area to prevent early stage skin lesions from occurring.

    Such patients must be instructed from childhood on foot care to help prevent skin pressure problems in the long term. This is a small, low-risk procedure, which corrects the calcaneal valgus and the characteristic of pes abductus by inserting a subtalar implant or stops screw in the subtalar joint space.

    The most effective treatment occurs during the years before the growth finishes ages 10 , depending on the stage of development. At this age, there are no other realistic conditions for a conservative corrective therapy, such that an alternative method to correcting calcaneal valgus does not exist.

    The Dwyer osteotomy is however available as an alternative surgical procedure that can be performed once the patient has finished growing. As pes valgus also shares the same characteristics as pes abductus, this deformity has to be distinguished from the previously mentioned procedure. Pes abductus cannot be completely corrected by Arthrorisis. Alternatively, the calcaneal lengthening osteotomy Evans osteotomy is also available. However, the risks of this surgical procedure are much higher than in arthrorisis.

    Furthermore, this approach is only indicated once the patient has finished growing. Simultaneous assessment of the entire leg axis should not be neglected, as genu valgum may exacerbate the symptoms of pes valgus. Under these circumstances, an orthopaedic examination is recommended between the ages of 10 and 12, as at this age the simple and low-risk corrective surgery of both pes valgus and knee-knocks, with arthroereisis and temporary epiphysiodesis respectively, is not delayed.

    In general, hyperlordosis of the lumbar vertebrae is the cause for lumbar discomfort. As abdominal girth increases, so too does the risk of hyperlordosis of the lumbar vertebrae, as well as lumbar discomfort and symptomatology.

    Muscular imbalance between the abdominal muscles and autochthonous muscles should be considered. The anatomical relationship between an upright posture and dorsal positioning of the spine, which causes, along with an abdominal distension, according to the lever-arm-law, a permanent strain on muscles of the back, particularly in obesity.

    Active physiotherapy to build muscular balance and core stability are paramount. Long-term effects are symptomatic with ageing. If the effects of the spinal adjustment to the lower extremities is investigated further, it is obvious that hyperlordosis of the lumbar vertebrae causes a tilt in the pelvis with shortening of the ventral hip flexors [Fig. The resulting position, even if the knee flexion adjustment is only slight, is associated with an increased retropatellar load.

    This is supported by clinical observations of frequent retropatellar complaints in children who are obese from an early age. If the increased retropatellar pressure is combined with genu valgum and with patellar lateralisation tendencies, then the retropatellar contact zone of the articular surface is reduced significantly and overloading is inevitable.

    Due to obesity, not only is there mechanical straining but also adverse hormonal factors affecting cartilage.

    It is obvious that, apart from correct axial alignment, weight loss would also affect the joints positively. Treatment is focused on physiotherapy and only in very rare cases surgical intervention becomes necessary.

    Independent predictors of recurrent fracture occurrence include: previous fracture, body weight, low bone mass, higher body mass index and lower levels of physical activity.

    In all cases, optimal nutrition for bone development should be encouraged through consumption of foods and drinks rich in calcium and vitamin D. In some cases vitamin D supplementation may also be warranted. Outlook In summary given the multiple adverse effects of obesity on the developing musculoskeletal system, initial clinical assessment should screen for relevant orthopaedic history, the presence of pain; and the presence of gait or functional impairments.

    If assessment reveals difficulties with the musculoskeletal system an initial physiotherapy assessment is warranted. An orthopaedic examination should be sought at the beginning of adolescence so that there is time to proactively address bony complaints before growth has ceased. Special attention has to be paid to the leg axis, to the positioning of the feet and to the spinal column. Timely orthopaedic review is vital if potential arthroereisis to correct the pes valgus and a temporary epiphysiodesis to correct the leg axis are to be considered.

    These simple and low-risk procedures should be seen as an investment toward a less troubling orthopaedic future. Summary There are a number of orthopaedic conditions caused by childhood obesity, which are of particular importance. Leg axis and pes valgus foot deformities must be assessed by orthopaedic examination at the beginning of adolescence. This is the best time for examination as the musculoskeletal system can be corrected for the future through simple procedures such as temporary epiphysiodesis and arthroereisis.

    Spinal discomfort and the associated posture problems require physiotherapy. Physiotherapy forms the basis for symptom relieving actions, which are seen in an overall concept together with weight loss.
