Abstract

Stresses and strains are major factors influencing growth, remodeling and repair of musculoskeletal tissues. Therefore, knowledge of forces and deformation within bones and joints is critical to gain insight into the complex behavior of these tissues during development, aging, and response to injury and disease. Sensors have been used in vivo to measure strains in bone, intraarticular cartilage contact pressures, and forces in the spine, shoulder, hip, and knee. Implantable sensors have a high impact on several clinical applications, including fracture fixation, spine fixation, and joint arthroplasty. This review summarizes the developments in strain-measurement-based implantable sensor technology for musculoskeletal research.

Highlights

  • Biomechanics plays a major role in orthopedic injury, disease, and treatment

  • This review summarizes the developments in strain measurementbased implantable sensor technology for musculoskeletal research in general, with a special emphasis on the knee joint

  • Implantable sensors in the hip joint Forces acting on implanted femoral components were measured in vivo by Rydell as early as 1966 [12]

Summary

Introduction

Biomechanics plays a major role in orthopedic injury, disease, and treatment. The form and function of the musculoskeletal system is primarily mechanical in nature, supporting and protecting the rest of the body, and facilitating movement and locomotion. Implantable sensors in the hip joint Forces acting on implanted femoral components were measured in vivo by Rydell as early as 1966 [12].
