Biomechanics in Orthopaedics

In clinical orthopaedics, an approach based on biomechanical knowledge is a prerequisite. Studies on load distribution, gait analysis and implants have been extensively published aiming to aid clinicians in the processes of decision making and evaluation of treatments prior to using them in clinical practice. However, despite powerful scientific methods, the relevance of biomechanical studies with clinical orthopaedics, the adaptability and tolerance of living tissue, and the impact of these studies for clinical practice is debatable. Indeed, these studies may have limited clinical relevance unless they account for important parameters such as biological behaviour, tissue tolerance and adaptability. This article summarizes the history of biomechanics in orthopaedics, and discusses the clinical relevance of biomechanical studies in orthopaedic and trauma surgery.
