– See: – Removal of Cemented Femoral Stems: – Removal of Press Fit Stems: – Discussion: – stem considerations: – calcar replacment: bone loss at the lower limit of the lesser trochanter may requires a 30-mm calcar replacement; – length: stems that are longer than 175 mm long … Read more
– Discusssion: – remove 1-2mm of bone using the intramedullary guide. – be aware of the preoperative flexion stability and ROM in choosing posterior slope; – for example, if the knee was unstable in flexion preoperatively, 0 degrees posterior slope may help reduce some of the flexion gap; … Read more
– Discussion: – quick femoral bone cuts by eye: – usually the femoral bone under the prosthesis will be soft, and will impact when the femoral trial is applied; – therefore, there is no need for time consuming bone cuts, when “eyed cuts” are just as good; – the main issue … Read more
