Ishii Y, et al. – In this assessment, the experts intended to analyze whether factors such as level of activity, quadriceps strength, body weight (BW), gender, age, and prosthetic design affect proximal tibial bone mineral density (BMD) after total knee arthroplasty (TKA). They concluded that BW was the most impactful factor on the proximal tibial BMD after mid– to long–term follow–up TKA. Therefore, the management of BW in TKA patients, probably contributes to the prevention of decline of tibial BMD.
