6. Doctor on the sidelines.

Effectively managing on-field emergencies is the most important role of the doctor on the sidelines. Pre-event preparation is essential and should include a formulated plan for dealing with emergencies and access to emergency equipment such as a stretcher and a bag and mask. Game day injuries should be assessed by adhering as closely as possible to a normal clinical consultation, with a proper history and examination being performed for all injuries. The athlete with an on-field head injury should be treated as having a concomitant cervical spine injury until proven otherwise. Athletes with any symptoms after head injury should be comprehensively and continuously assessed. Return-to-play decisions are made by balancing the risk of injury recurrence, the potential severity of injury recurrence and the benefits of returning to the field (which are higher at elite than amateur level). There is currently a shortage of doctors willing to cover sports events in Australia, which is partially explained by inadequate remuneration, inadequate facilities provided at venues, inadequate training opportunities in sports medicine, and fear of the medicolegal consequences in taking on the role as a team doctor.

5. Recent advances in sports medicine.

New research has changed our perception and management of common injuries. Magnetic resonance imaging and arthroscopy of the hip have shown that labral injuries, chondral injuries, rim lesions, synovitis and tears of the ligament teres are common causes of hip, groin and low-back pain. Hip arthroscopy is used both as a diagnostic and therapeutic tool; it has been shown to be of benefit in recent traumatic labral injury, but disappointing in the management of chronic hip pain (which may be associated with degenerative change, and chondral lesions of the acetabulum). The McConnell multimodal physiotherapy regimen is effective in treating patellofemoral pain. Anterior cruciate ligament rupture is three to five times more common in women, but neuromuscular training appears to decrease its incidence. Patellar tendon and hamstring grafts appear to be equally effective in anterior cruciate ligament reconstruction. Articular cartilage defects remain a significant problem, and the efficacy of treatments such as autologous chondrocyte implantation is still unclear.

Stress fractures: pathophysiology, epidemiology, and risk factors.

A stress fracture represents the inability of the skeleton to withstand repetitive bouts of mechanical loading, which results in structural fatigue and resultant signs and symptoms of localized pain and tenderness. To prevent stress fractures, an appreciation of their risk factors is required. These are typically grouped into extrinsic and intrinsic risk factors. Extrinsic risk factors for stress fractures are those in the environment or external to the individual, including the type of activity and factors involving training, equipment, and the environment. Intrinsic risk factors for stress fractures refer to characteristics within the individual, including skeletal, muscle, joint, and biomechanical factors, as well as physical fitness and gender. This article discusses these extrinsic and intrinsic risk factors, as well as the pathophysiology and epidemiology of stress fractures.

3. Is exercise good for you?

Physical activity can significantly reduce the risk of cardiovascular disease, diabetes, some forms of cancer, osteoporosis, obesity, falls and fractures, and some mental health problems. While the benefits of physical activity are clear, there is a slightly increased risk of sudden death while exercising (compared with while sedentary), especially in untrained people undertaking unaccustomed vigorous activity. Routine exercise testing yields a significant number of false-positive results, and has not been shown to prevent exercise-related acute cardiac events. There is no convincing evidence that exercise is itself associated with osteoarthritis, but significant joint injury which occurs during sport is associated with an increased risk of subsequent development of osteoarthritis.

Delayed- and non-union following opening wedge high tibial osteotomy: surgeons' results from 182 completed cases.

Opening wedge high tibial osteotomy (OWHTO) is a recently described procedure for medial compartment arthritis of the knee in the active, younger population. Despite having a number of advantages over the traditional closing wedge high tibial osteotomy (CWHTO) a potential complication of OWHTO is a high rate of delayed- and non-union. This study reports the occurrence of delayed- and non-union following OWHTO for medial compartment arthritis of the knee. Questionnaires were sent to all current members of the Australian Knee Society (n=45), a special interest group of the Australian Orthopaedic Group. Surgeons were asked primarily to indicate how many OWHTOs they had performed, and how many of these had progressed to union, delayed-union and non-union. All 45 questionnaires were returned, with 21 surgeons (47%) performing OWHTOs. A total of 188 OWHTO cases were reported, of which 182 were complete. Of these complete cases 167 (91.8%) were classed as united, 12 (6.6%) delay-united and 3 (1.6%) non-united. The results of this study demonstrate that the rate of delayed- and non-union following OWHTO for medial compartment arthritis of the knee is relatively low and comparable to that reported for traditional CWHTO.
