High tibial osteotomy is technically demanding. Risks include injury to the popliteal neurovascular bundle. The present goal was to further define this risk. ⋯ To perform a safe osteotomy, the knee should be positioned in 90 degrees of flexion with the saw angled less than 30 degrees from the coronal plane. A protective device deep to the popliteus may protect against popliteal injury.

Ankle sprain is a common injury in athletic populations that results in significant time lost to injury. ⋯ Higher mean height and weight in men, increased BMI in men, greater physical conditioning in men, and athlete exposure to selected sports were all risk factors for ankle sprain.

Low back pain is a significant problem not only for the adult, but also during youth. However, the relationship between low back pain during youth and the duration or types of competitive sports has not been clarified. ⋯ Excessive exposure to competitive sports activities during youth was associated with low back pain and symptoms in the lower extremities, with the severity varying with the sport. To reduce low back pain in youth, factors that may be causing low back pain, such as sport-specific postures and motions, need to be investigated.

Increase in expression of substance P (SP) and calcitonin gene-related peptide (CGRP) has been reported in clinical samples of tendinopathy. ⋯ There was increased expression of SP and CGRP after collagenase-induced tendon injury, and their expression was positively associated with double-stance duration. Clinical Relevance Substance P and CGRP might be involved in the pathogenesis and origin of pain of tendinopathy and could be the targets for future intervention.

Comparative Study
Skill level-specific differences in snowboarding-related injuries.
Snowboarding-related injuries have been associated with specific snowboarding skill levels, but differences in specific skill level have not been identified. ⋯ Prevalence of injury type, injury location, mechanism of injury, and percentage of protective gear use varied according to skill level, and the severity of the injury increased with increase in skill level. On the basis of our observations, we believe that snowboarding injury prevention strategies should be formulated according to skill level.
