STRESS-FRACTURE OF THE TIBIA AFTER TOTAL KNEE ARTHROPLASTY

We present a case of total knee arthroplasty in which the patient suff ered a transverse stress fracture of the tibia 2 weeks after replaceme nt without significant injury, Plain radiographs were obtained on even t presentation. Later radiographic examination showed the fracture and a periosteal reaction. The fracture healed after immobilising the lim b in a cast for 2 months. This case illustrates well an insufficiency fracture to the occurrence of stress risers in a weakened bone when su bjected to repetitive loading as a complication following total knee a rthroplasty.
