Introduction
Preoperative imaging for arthroplasty includes radiographs CT and MRI to assess bone stock alignment and soft tissue status and to plan implant selection and positioning. Postoperative imaging evaluates implant position fixation and complications such as loosening infection and periprosthetic fracture. Advanced imaging techniques address metal artifact and provide diagnostic clarity.
Preoperative Assessment
Weight bearing radiographs and CT based templating inform alignment and component sizing for joint replacement. MRI assesses soft tissue and cartilage when indicated for complex cases. 3D planning and navigation tools enhance surgical precision.
Postoperative Imaging
Plain radiographs are first line for routine follow up while CT and MRI with metal artifact reduction are used for suspected complications. Nuclear medicine and PET CT can help evaluate infection and loosening in equivocal cases. Standardized reporting of implant position and signs of failure supports clinical management.
Imaging Innovations
Low artifact sequences and photon counting CT improve visualization around metallic implants. 3D printing and virtual planning assist complex reconstructions and revision surgeries. Multidisciplinary collaboration between radiology and orthopedics optimizes patient outcomes.
