Clinicians base their diagnosis on observations, manual tests. medical imaging and the patients’ history. However, these are static assessments usually done while the knee is not in weight-bearing condition. Since symptoms chiefly manifest themselves when the knee is in movement, it is difficult to understand the origin of the problem.
Medical imaging is mainly used to confirm clinician’s diagnosis impressions; however radiographic conclusions don’t correlate well with the patient’s symptoms. Furthermore, they do not provide information allowing physicians to personalize the treatment plan to address the causes behind the symptoms.
Faced with the current clinical limitations, practitioners insist on the need for new tools to help guide the treatment plan. They become essential for better patient management and follow up.
Due to the influence of biomechanical changes on osteoarthritis (OA) progression, the type and the degree of abnormality should be included in the definition of OA since they may influence treatment outcome.
Biomechanics and kinematics contribute to the development of early osteoarthritis following joint injury or surgery and should be assessed.
Faulty joint mechanics is often the underlying cause of the development and progression of pathologies, such as in knee osteoarthritis.
Need to understand the adaptations and impacts of an injury on joint mechanics in order to implement a personalized treatment.
Need for an objective clinical measurement to adequately quantify the joint function.
Greater therapeutic attention to the important role of mechanical factors in OA etiopatholgenesis is required if we are to find ways of reducing the public health impact of this condition.
Need to produce a valid and precise assessment during the treatment phase.
