Clinical Scenario: Chronic ankle instability (CAI) is characterized by the residual symptoms and feelings of instability that persist after an acute ankle sprain. Current literature has identified several neuromuscular impairments associated with CAI that may negatively impact sagittal plane knee kinematics during dynamic activities. This has led researchers to begin examining sagittal plane knee kinematics during jump landing tasks. Understanding changes in movement patterns at the knee may assist clinicians in designing rehabilitation plans that target both the ankle and more proximal joints, such as the knee. Clinical Question: What is the evidence to support the notion that patients with CAI have decreased sagittal plane knee flexion angle at initial contact during a jump-landing task compared to healthy individuals? Summary of Key Findings: The literature was systematically searched for level 4 evidence or higher. The search yielded two case-control studies which met the inclusion criteria. Based on limited evidence, there are mixed results for whether sagittal plane knee kinematic at initial contact differ between those with and without CAI. Clinical Bottom Line: There is weak evidence to support changes in sagittal plane knee kinematics at initial contact during a jump landing in individuals with CAI compared to healthy controls. Strength of Recommendation: In accordance with the Centre for Evidence-Based Medicine, a grade of C for level 4 evidence is recommended due to variable findings.

Context: Although taping has been proven effective in reducing ankle sprain events in individuals with chronic ankle instability, insight into the precise working mechanism remains limited. Objectives: To evaluate whether the use of taping changes ankle joint kinematics during a sagittal and frontal plane landing task in subjects with chronic ankle instability. Design: Repeated measure design. Setting: Laboratory setting. Participants: A total of 28 participants with chronic ankle instability performed a forward and side jump landing task in a nontaped and taped condition. The taping procedure consisted of a double “figure of 6” and a medial heel lock. Main Outcome Measures: 3D ankle joint kinematics was registered. Statistical parametric mapping was used to assess taping effect on mean ankle joint angles and angular velocity over the landing phase. Results: For both the forward and side jump, a less plantar flexed and a less inverted position of the ankle joint were found in the preparatory phase till around touchdown (TD) in the taped condition (P < .05). In addition, for both jump landing protocols, a decreased dorsiflexion angular velocity was found after TD (P < .05). During the side jump protocol, a brief period of increased inversion angular velocity was registered after TD (P < .05). Conclusions: Taping is capable of altering ankle joint kinematics prior to TD, placing the ankle joint in a less vulnerable position at TD.

Injury Causation

Lateral ankle sprains (LASs) are a common injury sustained by individuals who participate in recreational physical activities and sports. After an LAS, a large proportion of individuals develop long-term symptoms, which contribute to the development of chronic ankle instability (CAI). Due to the prevalence of LASs and the propensity to develop CAI, collective efforts toward reducing the risk of sustaining these injuries should be a priority of the sports medicine and sports physiotherapy communities. The comprehensive injury-causation model was developed to illustrate the interaction of internal and external risk factors in the occurrence of the inciting injury. The ability to mitigate injury risk is contingent on a comprehensive understanding of risk factors for injury. The objective of this current concepts review is to use the comprehensive injury-causation model as a framework to illustrate the risk factors for LAS and CAI based on the literature.
