“…In plantar flexion, the contact area of the ankle joint decreases by greater than 40% with corresponding increases in peak stresses . This may partially explain the high incidence of ankle OA in retired ballet dancers and early subclinical disease in a cohort of active professional dancers . During eversion and inversion, contact area also decreases, and peak stresses increase .…”

The diagnosis of ankle osteoarthritis (OA) is increasing as a result of advancements in non-invasive imaging modalities such as magnetic resonance imaging, improved arthroscopic surgical technology and heightened awareness among clinicians. Unlike OA of the knee, primary or age-related ankle OA is rare, with the majority of ankle OA classified as post-traumatic (PTOA). Ankle trauma, more specifically ankle sprain, is the single most common athletic injury, and no effective therapies are available to prevent or slow progression of PTOA. Despite the high incidence of ankle trauma and OA, ankle-related OA research is sparse, with the majority of clinical and basic studies pertaining to the knee joint. Fundamental differences exist between joints including their structure and molecular composition, response to trauma, susceptibility to OA, clinical manifestations of disease, and response to treatment. Considerable evidence suggests that research findings from knee should not be extrapolated to the ankle, however few ankle-specific preclinical models of PTOA are currently available. The objective of this article is to review the current state of ankle OA investigation, highlighting important differences between the ankle and knee that may limit the extent to which research findings from knee models are applicable to the ankle joint. Considerations for the development of new ankle-specific, clinically relevant animal models are discussed.

“…Maximal ankle plantar flexion and "over-pointed" foot may also accelerate the progression of hallux valgus and exacerbate the symptoms [7,30]. Furthermore, signs of osteoar thritis in the first metatarsophalangeal joint were found to be associated with hallux rigidus and hallux valgus in the general population and among professional elite ballet dancers [3,31]. Hallux valgus poses significant functional limita tions, such as foot pain, formation of painful bun ions on the medial border of the first MP joint, immobility, and poor balance [27,30,38], Surgi cal correction is the most invasive treatment option in the general population and in juveniles, with more than 100 different techniques being described in the literature [24,29].…”

The Association between Hallux Valgus and Proximal Joint Alignment in Young Female Dancers

Very little is known about the relationship between proximal joint alignment and hallux valgus among young dancers. This study sought to determine the extent to which spinal and lower extremity alignments are involved in hallux valgus, and to identify predicting variables for its development in young dancers. A group of 1336 young female dancers aged 8-16 years, and 226 control participants of the same age cohort were screened for the presence of hallux valgus, body physique characteristics, joint range of motion, and anatomical anomalies. Hallux valgus was common in the 2 young female populations studied. Among the dancers, 40.0% had bilateral hallux valgus and 7.3% unilateral. Among the controls, 32.3% had bilateral and 1.8% unilateral hallux valgus (χ2=8.27, df=1, p=0.004). Following logistic regression analysis, age (OR=1.028, 95% CI=0.968-1.091), genu varum (OR=1.514; CI=1.139-2.013) and scoliosis (OR=2.089; CI=1.113-3.921) were found to be significant predicting factors for hallux valgus in the dancer group, whereas in the control group, the predicting factors were age (OR=0.911, 95% CI=0.801-1.036) and ankle plantar flexion range of motion (OR=0.972; CI=0.951-0.992). In conclusion, it was found that spinal deformity, lower extremity alignment, and joint range of motion are strongly related to hallux valgus.
