- Recently, as the elderly population increases, the incidence of total knee arthroplasty has increased, with a concomitant increase in the frequency of periprosthetic fractures. To determine the treatment plan for fractures, the treatment method should be determined by the patient's age, osteoporosis, fixation status of the implant, and type of fracture. In recent years, operative treatment with reduction and stable fixation, rather than non-operative treatment, was used to promote early joint movement and gait. On the other hand, it is necessary to select an appropriate operative method to reduce complications of surgery, such as nonunion and infection, and expect a good prognosis. In this review, periprosthetic fractures were divided into femur, tibia, and patella fractures, and their causes, risk factors, classification, and treatment are discussed.

The study examined the fusion site and characteristics of the subtalar arthrodesis after intraarticular calcaneal fractures using computed tomography. MATERIALS AND METHODS The clinical results and computed tomographic analysis of the fusion site were reviewed in 18 patients who were followed-up for a minimum of six months after undergoing subtalar arthrodesis due to traumatic arthritis caused by an intra-articular calcaneal fracture from December 2012 to April 2017. RESULTS An evaluation of clinical results after subtalar arthrodesis revealed statistically significant improvements. In all cases, arthritis was found in the injured articular surface, which was displaced superolaterally from the initial primary fracture line of the calcaneus. Six months after arthrodesis, the subtalar fusion rate was 80.0% (16/20). Of these, 14 cases had a cannulated screw inserted in the uninjured site that is medial to the primary fracture line. Joint fusion was observed on the uninjured articular surface in 17 cases (85.0%). CONCLUSION Joint fusion was initially achieved at the uninjured posterior facet after subtalar arthrodesis due to traumatic arthritis caused by a displaced intra-articular calcaneal fracture. This suggests that meticulous surgical techniques and cannulated screw positioning at the uninjured site will promote joint fusion.
