Abstract:
The early loosening after total knee arthroplasty is one of the most serious complications. For the purpose of prevention against the complication, many researches were carried out in implant's quality, design and operative technique, etc. The mechanism of the loosening after arthroplasty is considered that micromotion makes a gap between implant and bone, the subsidence of implant and osteolysis around the implant. The authors found one case of the early isolated loosening of patellar component in a patient who had undergone primary total knee arthroplasty for osteoarthritis thirteen month ago. We tried to elucidate the mechanism of the early loosening by clinical and radiologic assessment of this case.
