The authors present the case of an 81-year-old man who, despite an anatomically aligned total knee arthroplasty, continued to have knee pain. The patient's ipsilateral rigid flatfoot caused by an earlier partial pedal amputation resulted in a valgus moment during gait, thus creating clinical symptoms in the total knee arthroplasty. Because of the deformity and scarring within the flatfoot, this...

BACKGROUND Severe arthritis of the knee is a disabling condition, with over 50,000 knee replacements performed each year in the UK. Isolated patellofemoral joint arthritis occurs in over 10% of these patients with the treatment options being patellofemoral arthroplasty or total knee arthroplasty. Whilst many surgeons believe total knee arthroplasty is the 'gold standard' treatment for severe kn...

  In this report we describe a 78-year-old man whose total knee arthroplasty showed the symptoms of infection with brucella with radiographic signs of loosening 5 years after the index surgery. The patient was treated successfully after a 2-stage revision arthroplasty surgery along with using rifampicin and doxycycline for 8 weeks.

PURPOSE To compare clinical outcome of revision total knee arthroplasty (TKA) between the infected and non-infected groups. MATERIALS AND METHODS This study compared the clinical and radiographic results of 21 infected and 15 non-infected revision TKAs at a minimum 2-years follow-up. Clinical evaluations were assessed using the range of motion (ROM), Hospital for Special Surgery (HSS) score, ...

Of a consecutive series of 692 revision total knees at 3 centers, intraoperative cultures were unexpectedly found to be positive in 41 cases (5.9%). Of the 41, 29 (71%) cases had a single positive intraoperative culture and were determined to be a probable false positive based on absence of any other evidence of infection, of which 5 were treated with extended course of intravenous antibiotics ...

Stress fracture of the femoral neck is a rare complication of total knee arthroplasty. We report a case of femoral neck fracture following revision arthroplasty of the ipsilateral knee. Contributing factors may have been the patient's osteoporosis and a period of immobilisation before the revision arthroplasty. The patient was treated successfully with hemiarthroplasty of the hip. In patients w...

We have previously developed a radiographic technique, the oblique posterior condylar view, for assessment of the posterior aspect of the femoral condyles after total knee arthroplasty. The purpose of this study was to confirm the validity of this radiographic view based upon intra-operative findings at revision total knee arthroplasty. Lateral and oblique posterior condylar views were performe...

Consensus regarding femoral stem fixation options in revision total knee arthroplasty remains controversial. Tapered, modular, fluted titanium (TMFT) stems have an excellent track record in total hip arthroplasty for their ability to provide axial and rotational stability in situations of compromised host bone. We present 3 successfully treated cases in which the Food & Drug Administration gran...

BACKGROUND AND PURPOSE The long-term outcome of patellofemoral arthroplasty is related to progression of femorotibial osteoarthritis with need for conversion to total knee arthroplasty. We investigated whether prior patellofemoral arthroplasty compromises the results of total knee arthroplasty. METHODS 13 patients who had had 14 Richards type II patellofemoral arthroplasties converted to tota...
